Introduction
Product information
We recommend using genuine MercedesBenz parts as well as conversion parts and
accessories explicitly approved by us for your
vehicle model.
We have tested these parts to determine their
reliability, safety and special suitability for
Mercedes-Benz vehicles. Despite ongoing
market research, Mercedes-Benz is unable to
assess other parts. We cannot therefore be
held responsible for them, even if in individual
cases an official approval or authorization by
governmental or other agencies should exist.
The use of non-approved parts could affect
your vehicle's operating safety. MercedesBenz therefore recommends that you use
genuine Mercedes-Benz parts, conversion
parts and accessories that have been
approved for the type of vehicle. Genuine
Mercedes-Benz parts, approved conversion
parts and accessories are available from any
authorized Mercedes-Benz Center. In
addition, you will receive advice about
permissible technical modifications, and the
parts will be professionally installed.

Operating safety
Safety notes
G Warning

Work improperly carried out on electronic
components and associated software could
cause them to cease functioning. Because the
vehicle's electronic components are
interconnected, any modifications made may
produce an undesired effect on other
systems. Electronic malfunctions could
seriously impair the operating safety of your
vehicle.
Contact an authorized Mercedes-Benz Center
for repairs or modifications to electronic
components.
Other improper work or modifications on the
vehicle could also have a negative impact on
the operating safety of the vehicle.
Some safety systems only function when the
engine is running. You should therefore never
turn off the engine while driving.

G Warning

Heavy blows against the vehicle underbody or
tires/wheels may cause serious damage and
impair the operating safety of your vehicle.
Such blows can be caused, for example, by
running over an obstacle, road debris or a
pothole. If you feel a sudden significant
vibration or ride disturbance, or you suspect
that damage to your vehicle has occurred:

and optional equipment of your vehicle
which was available at the time of
purchase. Country-specific differences are
possible. Bear in mind that your vehicle
may not feature all functions described
here. This also refers to safety-related
systems and functions.

Occupant safety
Overview of occupant safety
In this section you will learn the most
important facts about the restraint system
components of the vehicle.
The restraint systems are:
RSeat

belts
restraint systems
RLATCH-type (ISOFIX) child seat anchors
Additional protection is provided by:
RChild

RSRS

(Supplemental Restraint System)
head restraints
RPRE-SAFE®
RAir bag system components with:
- PASSENGER air bag OFF indicator lamp
- USA only: front passenger seat with
Occupant Classification System (OCS)
- Canada only: front passenger seat with
BabySmart™ air bag deactivation system
The different air bag systems work
independently of each other. The protective
functions of the systems work in conjunction
with each other. Not all air bags are deployed
in an accident.
RNECK-PRO

G Warning

Modifications to or work improperly
conducted on restraint system components
or their wiring, as well as tampering with
interconnected electronic systems, can lead

to the restraint systems no longer functioning
as intended.
Air bags or Emergency Tensioning Devices
(ETDs), for example, could deploy
inadvertently or fail to deploy in accidents
although the deceleration threshold for air
bag deployment is exceeded. Therefore,
never modify the restraint systems. Do not
tamper with electronic components or their
software.

i See "Children in the vehicle"
(Y page 58) for more information on
infants and children traveling with you in
the vehicle and restraints for infants and
children.

SRS (Supplemental Restraint System)
Introduction
SRS reduces the risk of occupants coming
into contact with the vehicle's interior in the
event of an accident. It can also reduce the
effect of the forces to which occupants are
subjected during an accident.
SRS consists of:
Rthe

6 SRS warning lamp
bags
Rair bag control unit (with crash sensors)
Rbelt tensioners
Rbelt force limiters
Rair

SRS warning lamps
SRS functions are checked regularly when
you switch on the ignition and when the
engine is running. Therefore, malfunctions
can be detected in good time.
The 6 SRS warning lamp in the instrument
cluster lights up when the ignition is switched
on. It goes out no later than a few seconds
after the engine is started.
The SRS components are in operational
readiness when the 6 SRS warning lamp
is not lit while the engine is running.

2010-05-20T13:33:46+02:00 - Seite 37
Version: 3.0.3.6

Occupant safety
G Warning

The SRS self-check has detected a
malfunction if the 6 SRS warning lamp:
Rdoes

not come on at all
to go out approximately 4 seconds
after the engine was started
Rcomes on after the engine was started or
while driving
For your safety, Mercedes-Benz strongly
recommends that you have the system
checked as soon as possible at an authorized
Mercedes-Benz Center. Otherwise the SRS
may not be activated when it is needed in an
accident, which could result in serious or fatal
injury. The SRS might also deploy
unexpectedly and unnecessarily which could
also result in injury.
In addition, improper work on the SRS creates
a risk of rendering the SRS inoperative or
causing unintended air bag deployment. Work
on the SRS must therefore only be performed
by qualified technicians. Contact an
authorized Mercedes-Benz Center.
If it is necessary to modify an air bag system
to accommodate a person with disabilities,

Safety guidelines for seat belts,
Emergency Tensioning Devices (ETDs)
and air bags
G Warning

RDamaged seat belts or seat belts that have

been subjected to stress in an accident
must be replaced. Their anchoring points
must also be checked. Only use seat belts
installed or supplied by an authorized
Mercedes-Benz Center.
RAir bags and pyrotechnic Emergency
Tensioning Devices (ETDs) contain
perchlorate material, which may require
special handling and regard for the

environment. Check your national disposal
guidelines. California residents, see
www.dtsc.ca.gov/HazardousWaste/
Perchlorate/index.cfm.
RAir bags and ETDs are designed to function
on a one-time-only basis. An air bag or ETD
that has deployed must be replaced. PRESAFE® has electrically operated reversible
belt tensioners in addition to the
pyrotechnic ETDs.
RDo not pass seat belts over sharp edges.
They could tear.
RDo not make any modification that could
change the effectiveness of the seat belts.
RDo not bleach or dye seat belts as this may
severely weaken them. In a crash they may
not be able to provide adequate protection.
RNo modifications of any kind may be made
to any components or wiring of the SRS.
RDo not change or remove any component
or part of the SRS.
RDo not install additional trim material, seat
covers, badges, etc. to the:
- padded steering wheel boss
- knee bag covers
- front-passenger air bag cover
- outer side of front seat bolsters
- side trim next to the rear seat backrest
- roof lining trim
RDo not install additional electrical/
electronic equipment on or near SRS
components and wiring.
RKeep area between air bags and occupants
free of objects (e.g. packages, purses,
umbrellas, etc.).
RDo not hang items such as coat hangers
from the coat hooks or handles over the
door. These items may be thrown around in
the vehicle and cause head and other
injuries when the window curtain air bag is
deployed.
RAir bag system components will be hot after
an air bag has inflated. Do not touch them.

place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.
RImproper repair work on the SRS creates a
risk of rendering the SRS inoperative or
causing unintended air bag deployment.
Work on the SRS must therefore only be
performed by qualified technicians.
Contact an authorized Mercedes-Benz
Center.
RFor your protection and the protection of
others, when scrapping the air bag unit or
ETD, our safety instructions must be
followed. These instructions are available
from any authorized Mercedes-Benz
Center.
RGiven the considerable deployment speed,
required inflation volume, and the material
of the air bags, there is the possibility of
abrasions or other, potentially more serious
injuries resulting from air bag deployment.

If you sell your vehicle, Mercedes-Benz
strongly recommends that you inform the
subsequent owner that the vehicle is
equipped with SRS. Also refer them to the
applicable section in the Operator's Manual.

Air bags
Important safety notes
G Warning

Air bags are designed to reduce the incidence
of injuries and fatalities in certain situations:
Rfrontal

impacts (driver's and frontpassenger front air bags and driver's knee
bag)
Rside impacts (side impact air bags, window
curtain air bags and pelvis air bags)
Rrollover (window curtain air bags)
However, no system available today can
completely eliminate injuries and fatalities.

When the air bags are deployed, a small
amount of powder is released. The powder
generally does not constitute a health hazard
and does not indicate that there is a fire in the
vehicle. In order to prevent potential
breathing difficulties, you should leave the
vehicle as soon as it is safe to do so. If you
have any breathing difficulty but cannot get
out of the vehicle after the air bag inflates,
then get fresh air by opening a window or
door.

G Warning

To reduce the risk of injuries during front air
bag inflation, the driver and front-passenger
must always be seated correctly and have
their seat belts fastened accordingly.
For maximum protection in the event of a
collision, you must always be in the normal
seat position with your back against the
backrest. Fasten your seat belt and make sure
that it is correctly positioned on your body.
Since the air bag inflates with considerable
speed and force, a proper seating position
and correct positioning of the hands on the
steering wheel will help to keep you at a safe
distance from the air bag. Occupants who are
not wearing their seat belt, are not seated
properly or are too close to the air bag can be
seriously injured or killed by an air bag as it
inflates with great force instantaneously:
RSit with the seat belt properly fastened in a

position that is as upright as possible with
your back against the seat backrest.
RMove the driver's seat as far back as
possible, still permitting proper operation
of vehicle controls. The distance from the
center of the driver's chest to the center of
the air bag cover on the steering wheel
must be at least 10 inches(25 cm) or more.
You should be able to accomplish this by
adjusting the seat and steering wheel. If
you have any difficulties, please contact an
authorized Mercedes-Benz Center.
RDo not lean your head or chest close to the
steering wheel or dashboard.

hold the steering wheel by the rim.
Placing hands and arms inside the rim can
increase the risk and potential severity of
hand/arm injury when the driver front air
bag inflates.
RAdjust the front-passenger seat as far back
as possible from the dashboard when the
seat is occupied.
ROccupants, especially children, should
never place their bodies or lean their heads
in the area of the door where the side
impact air bag inflates. This could result in
serious injuries or death should the side
impact air bag be deployed. Always sit as
upright as possible, wear the seat belt
properly and use an appropriately sized
child restraint, infant restraint or booster
seat recommended for the size and weight
of the child.
RCanada only: children under 12 years may
only sit in the front-passenger seat if they
are seated in a child restraint system which
is compatible with BabySmart™ and
approved by Mercedes-Benz. If the child
restraint system is installed properly, the
front-passenger front air bag is deactivated
in conjunction with the BabySmart™
system installed in the vehicle. Otherwise,
the child could be struck by the air bag
when it inflates in a crash. This could lead
to serious or fatal injuries.
Failure to follow these instructions can result
in severe injuries to you or other occupants.
If you sell your vehicle, it is important that you
make the buyer aware of this safety
information. Be sure to give the buyer this
Operator's Manual.

G Warning

Accident research shows that the safest place
for children in an automobile is in a rear seat.
A side impact air bag related injury may occur
if occupants, especially children, are not
properly seated or restrained when next to a
side impact air bag which needs to deploy
rapidly in a side impact in order to do its job.

To help avoid the possibility of injury, please
follow these guidelines:
(1)

(2)

Always sit as upright as possible
and use the seat belts properly.
Make sure that children 12 years
old and under use an appropriately
sized child restraint, infant
restraint, or booster seat
recommended for the size and
weight of the child.
Always wear seat belts properly.

Safety

ROnly

39

The air bags are only deployed if the airbag
control unit detects the need for deployment.
Only in the event of such a situation will they
provide their supplemental protection.
The driver and passenger should always wear
their seat belts. Otherwise, it is not possible
for the air bags to provide their supplemental
protection.
In the event of other types of impacts and
impacts below air bag deployment
thresholds, air bags will not deploy. The driver
and passengers will then be protected to the
extent possible by a properly fastened seat
belt. A properly fastened seat belt is also
needed to provide the best possible
protection in a rollover.
Air bags offer supplemental protection but
are not a substitute for seat belts. All vehicle
occupants must fasten their seat belts
regardless of whether your vehicle is
equipped with airbags or not.
It is important for your safety and that of your
passenger to have deployed air bags replaced
and to have any malfunctioning air bags
repaired. This will help to make sure the air
bags continue to perform their protective
function for the vehicle occupants in the
event of a crash.

G Warning

According to accident statistics, children are
safer when properly restrained on the rear
seats than on the front-passenger seat. Thus,
we strongly recommend that children be
placed in the rear seats whenever possible.
Regardless of seating position, children 12
years old and under must be seated and
properly secured in an appropriate infant
restraint, toddler restraint, or booster seat
recommended for the size and weight of the
child.
The infant or child restraint must be properly
secured with the vehicle's seat belt, the seat
belt and Top Tether strap, or lower anchors
and Top Tether strap, fully in accordance with
the child seat manufacturer's instructions.

Occupant safety
Occupants, especially children, should always
sit as upright as possible, wear the seat belt
properly and use an appropriately sized infant
restraint, toddler restraint, or booster seat
recommended for the size and weight of the
child.
Children can be killed or seriously injured by
an inflating air bag. Note the following
important information when circumstances
require you to place a child in the frontpassenger seat:
RYour

vehicle is equipped with air bag
technology designed to deactivate the
front-passenger front air bag in your vehicle
when the system senses the weight of a
typical 12-month-old child or less along
with the weight of a standard appropriate
child restraint on the front-passenger seat.
RA child in a rear-facing child restraint on the
front-passenger seat will be seriously
injured or even killed if the front-passenger
front air bag inflates in a collision which
could occur under some circumstances,
even with the air bag technology installed
in your vehicle. The only means to eliminate
this risk completely is never to place a child
in a rear-facing child restraint in the frontpassenger seat. We therefore strongly
recommend that you always place a child
in a rear-facing child restraint on the rear
seat.
RIf you install a rear-facing child restraint on
the front-passenger seat, make sure the
45 indicator lamp is illuminated,
indicating that the front-passenger front air
bag is deactivated. Should the 45
indicator lamp not illuminate or go out while
the restraint is installed, please check
installation. Periodically check the
45 indicator lamp while driving to
make sure that the 45 indicator
lamp is illuminated. If the 45
indicator lamp goes out or remains out, do
not transport a child on the front-passenger
seat until the system has been repaired.

A child in a rear-facing child restraint on the
front-passenger seat will be seriously
injured or even killed if the front-passenger
front air bag inflates.
RIf you place a child in a forward-facing child
restraint on the front-passenger seat:
- move the seat as far back as possible
- use the proper child restraint
recommended for the age, size and
weight of the child
- secure child restraint with the vehicle's
seat belt according to the child seat
manufacturer's instructions
RFor children larger than the typical 12month-old child, the front-passenger front
air bag may or may not be activated.

Deployment of the driver front air bag does
not mean that the front-passenger front air
bag should also have deployed.
OCS may have determined:
Rthat

the seat was unoccupied or occupied
by a weight of up to or less than that of a
typical 12-month-old child seated in a
standard child restraint
Rthat the seat was occupied by a small
individual (e.g. a young teenager or a small
adult) or a child who weighs more than a
typical 12-month-old child in a standard
child restraint system
These are examples of when OCS deactivates
the front-passenger front air bag. The air bag
is deactivated despite the impact fulfilling the
criteria for deploying the driver's front air bag.

The BabySmart™ system is standard
equipment in Canada.

G Warning

According to accident statistics, children are
safer when properly restrained on the rear
seats than on the front-passenger seat. For
this reason, Mercedes-Benz strongly advises
that you always secure children in the rear
seats. Regardless of seating position, children
12 years old and under must be seated and
properly secured in an appropriately sized
child restraint system or booster seat
recommended for the size and weight of the
child.
Secure the infant restraint system or child
restraint system, using:
Rthe

vehicle's seat belt
seat belt and a Top Tether belt
Rthe LATCH-type (ISOFIX) child seat mount
and a Top Tether belt
The child restraint system must be installed
and secured correctly, observing the
manufacturer's installation instructions.
Occupants, especially children, should always
sit as upright as possible, wear the seat belt
properly and use an appropriately sized infant
restraint, toddler restraint, or booster seat
recommended for the size and weight of the
child.
Children can be killed or seriously injured by
an inflating air bag. Observe the following
important information if it is necessary to
carry a child on the front-passenger seat:
Rthe

RChildren under 12 years may only sit in the

front-passenger seat if they are seated in a
child restraint system which is compatible
with BabySmart™ and approved by
Mercedes-Benz. If the child restraint
system is installed properly, the front-

passenger front air bag is deactivated in
conjunction with the BabySmart™ system.
Otherwise, the child could be struck by the
air bag when it inflates in a crash. This could
lead to serious or fatal injury.
RA child in a rear-facing child restraint on the
front-passenger seat will be seriously
injured or even killed if the front-passenger
front air bag inflates in a collision which
could occur under some circumstances,
even with the air bag technology installed
in your vehicle. The only means to eliminate
this risk completely is never to place a child
in a rear-facing child restraint in the frontpassenger seat. We therefore strongly
recommend that you always place a child
in a rear-facing child restraint on the rear
seat.
RIf it is necessary to install a BabySmart™compatible rear-facing child restraint
system on the front-passenger seat, make
sure the 45 indicator lamp is
illuminated. This indicates that the frontpassenger front air bag is deactivated. If the
45 indicator lamp does not light up
or goes out when the child restraint system
is installed, check the anchorages of the
restraint system. Periodically check the
45 indicator lamp while driving to
make sure the 45 is illuminated. If
the 45 indicator lamp goes out or
remains out, do not transport a child on the
front-passenger seat until the system has
been repaired.

G Warning

The BabySmart™ air bag disabling system
ONLY works with specially adapted child
restraint systems. It does not work with child
restraint systems that are not compatible with
BabySmart™.
Never place anything between the seat
cushion and the child restraint system (e.g. a
cushion), as this reduces the effectiveness of
the BabySmart™ air bag deactivation system.
The underside of the child restraint system
must lie against the seat cushion of the frontpassenger seat. In the event of an accident,
an incorrectly installed child restraint system
could injure the child instead of offering
protection.
Observe the manufacturer's instructions
when installing special child restraint
systems.

G Warning

When using a BabySmart™-compatible child
restraint system on the front-passenger seat,
the front-passenger front air bag is only
disabled if the 45 indicator lamp is
illuminated.

G Warning

The PRE-SAFE® system reduces the impact of
an accident on vehicle occupants, as long as

Although your vehicle is equipped with a PRESAFE® system, the possibility of injury in the
event of an accident cannot be ruled out. You
should therefore always drive carefully and
adapt your driving style to the prevailing road,
weather and traffic conditions.

footwell or behind the seats when resetting
the seats. There is a risk that the seats
and/or the objects could be damaged.
More information about belt adjustment, a
convenience function integrated into PRE-

SAFE®, can be found in the "Belt adjustment"
section (Y page 56).

NECK-PRO head restraints
The NECK-PRO head restraints increase
protection for the driver's and frontpassenger's head and neck. In the event of a
rear collision of a certain severity, the NECKPRO head restraints on the driver's and frontpassenger seats are moved forwards and
upwards. This provides better head support.

G Warning

Do not secure any objects (e.g. coat hangers)
on the NECK-PRO head restraints. Otherwise,
the NECK-PRO head restraints may not
function properly, or in the event of a rear-end
collision may not be able offer the level of
protection they are designed to provide.

G Warning

Only use seat covers/head restraint covers
that have been tested and approved by
Mercedes-Benz for your model.
Using seat covers and head restraint covers
other than those recommended may cause a
malfunction when NECK-PRO head restraints
are triggered or front side impact air bags/
pelvis air bags may be prevented from
deploying.
Contact an authorized Mercedes-Benz Center
for availability.

If the NECK-PRO head restraints have been
triggered in an accident, you must reset the
NECK-PRO head restraints on the driver's and
front-passenger seat (Y page 53).
Otherwise, the additional protection will not
be available in the event of another rear-end
collision. You can recognize that NECK-PRO
head restraints have been triggered by the
fact that they have moved forwards and can
no longer be adjusted.

Occupant safety

For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint so that it is as close
to the head as possible and the center of the
head restraint supports the back of the head
at eye level. This will reduce the potential for
injury to the head and neck in the event of an
accident or similar situation.

restraints
G Warning

For safety reasons, have the NECK-PRO head
restraints checked at an authorized
Mercedes-Benz Center after a rear-end
collision.

G Warning

When pushing back the NECK-PRO head
restraint cushion, make sure your fingers do
not become caught between the head
restraint cushion and the cover. Failure to
observe this could result in injuries.

i Resetting the NECK-PRO head restraints
requires a lot of strength. If you have
difficulty resetting the NECK-PRO head
restraints, have this work carried out at a
qualified specialist workshop, e.g. an
authorized Mercedes-Benz Center.

Example: Sedan

X Repeat this procedure for the second
NECK-PRO head restraint.

Seat belts
Important safety notes
The use of seat belts and infant and child
restraint systems is required by law in all 50
states, the District of Columbia, the U.S.
territories and all Canadian provinces.
Even where this is not the case, all vehicle
occupants should have their seat belts
fastened when the vehicle is in motion.

i See "Children in the vehicle"
(Y page 58) for more information on
infants and children traveling with you in
the vehicle and restraints for infants and
children.

G Warning!

Always fasten your seat belt before driving off.
Always make sure all of your passengers are
properly restrained. You and your passengers
should always wear seat belts.
Failure to wear and properly fasten and
position your seat belt greatly increases your
risk of injuries and their likely severity in an
accident.
If you are ever in an accident, your injuries can
be considerably more severe without your
seat belt properly buckled. Without your seat
belt buckled, you are much more likely to hit
the interior of the vehicle or be ejected from
it. You can be seriously injured or killed.

Version: 3.0.3.6

G Warning

Never ride in a moving vehicle with the seat
backrest in an excessively reclined position as
this can be dangerous. You could slide under
the seat belt in a collision. If you slide under
it, the seat belt would apply force at the
abdomen or neck. That could cause serious
or even fatal injuries. The seat backrest and
seat belt provide the best restraint when the
wearer is in a position that is as upright as
possible and the seat belt is properly
positioned on the body.

G Warning

Never let more people ride in the vehicle than
there are seat belts available. Make sure
everyone riding in the vehicle is correctly
restrained with a separate seat belt. Never
use a seat belt for more than one person at a
time.

G Warning

Damaged seat belts or seat belts that have
been subjected to stress in an accident must
be replaced and their anchoring points must
also be checked.
Only use seat belts which have been approved
by Mercedes-Benz.
Do not make any modifications to the seat
belts. This can lead to unintended activation
of the ETDs or to their failure to activate when
necessary.
Do not bleach or dye seat belts as this may
severely weaken them. In a crash they may
not be able to provide adequate protection.
Have all work carried out only by qualified
technicians. Contact an authorized
Mercedes-Benz Center.

Correct use of the seat belt
G Warning

USE SEAT BELTS PROPERLY
RSeat

belts can only work when used
properly. Never wear seat belts in any other
way than as described in this section, as
that could result in serious injuries in the
event of an accident.
REach occupant should wear their seat belt
at all times, because seat belts help reduce
the likelihood of and potential severity of
injuries in accidents, including rollovers.
The integrated restraint system includes
SRS (driver front air bag, driver's side knee
bag, front-passenger front air bag, side
impact air bags, pelvis air bags, window
curtain air bags for the side windows),
Emergency Tensioning Devices, seat belt
force limiters, and front seat knee bolsters.
The system is designed to enhance the
protection offered to properly belted
occupants in certain frontal (front air bags,
driver's side knee bag and ETDs) and side
(side impact air bags, window curtain air
bags, and ETDs) impacts which exceed
preset deployment thresholds and in
certain rollovers (window curtain air bags
and ETDs).
RNever wear the shoulder belt under your
arm, across your neck or off your shoulder.
In a frontal crash, your body would move
too far forward. That would increase the
chance of head and neck injuries. The seat
belt would also apply too much force to the
ribs or abdomen, which could severely
injure internal organs such as your liver or
spleen.
Adjust the seat belt so that the shoulder
section is located as close as possible to
the middle of the shoulder. It should not
touch the neck. Never pass the shoulder
portion of the seat belt under your arm. For
this purpose, you can adjust the height of
the seat belt outlet.

RNever wear seat belts over rigid or
breakable objects in or on your clothing,
such as eyeglasses, pens, keys etc., as
these might cause injuries.
RMake sure the seat belt is always fitted
snugly. Take special care of this when
wearing loose clothing.
RNever use a seat belt for more than one
person at a time. Do not fasten a seat belt
around a person and another person or
other objects at the same time.
RSeat belts should not be worn twisted. In a
crash, you would not have the full width of
the seat belt to distribute impact forces.
The twisted seat belt against your body
could cause injuries.
RPregnant women should also always use a
lap-shoulder belt. The lap belt portion
should be positioned as low as possible on
the hips to avoid any possible pressure on
the abdomen.
RPlace the seat backrest in a position that is
as upright as possible.
RCheck your seat belt during travel to make
sure it is properly positioned.
RNever place your feet on the instrument
panel, dashboard, or on the seat. Always
keep both feet on the floor in front of the
seat.
RWhen using a seat belt to secure infant
restraints, toddler restraints, or children in
booster seats, always follow the child seat
manufacturer's instructions.

G Warning

Do not pass seat belts over sharp edges. They
could tear.
Do not allow the seat belt to get caught in the
door or in the seat adjustment mechanism.
This could damage the seat belt.

55

Never attempt to make modifications to seat
belts. This could impair the effectiveness of
the seat belts.

Fastening seat belts
G Warning

According to accident statistics, children are
safer when properly restrained on the rear
seats than on the front-passenger seat. Thus,
we strongly recommend that children be
placed in the rear seat whenever possible.
Regardless of seating position, children 12
years old and under must be seated and
properly secured in an appropriately sized
child restraint system or booster seat
recommended for the size and weight of the
child. For additional information, see the
"Children in the vehicle" section.
A child's risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and/
or the child is not properly secured in the child
restraint.

G Warning

Canada only: children 12 years old and under
may ride on the front seat if a BabySmart™
compatible child restraint system is installed
on the front-passenger seat. Use only
Mercedes-Benz approved BabySmart™
compatible child restraint systems. A
BabySmart™ compatible child restraint
system will deactivate the front-passenger
front air bag when installed correctly. The
front-passenger front air bag will not be
deactivated if the child restraint systems that
are installed are not BabySmart™ compatible
or if BabySmart™ compatible child restraint
systems are not installed correctly. If the
front-passenger front air bag is deployed in a
collision, the child will be struck by the air bag.
If this happens, serious or fatal injury will
result.

Seat belt force limiters, when activated, are
employed to help reduce the force exerted by
the seat belts on occupants during a crash.
The front belt force limiters are synchronized
with the front air bags, which take on a part
of the deceleration force. Thus, the force
exerted on the occupant is distributed over a
greater area.

Important safety notes
G Warning

Observe "Important safety notes"
(Y page 58).

We recommend all infants and children be
properly restrained using the child restraint
systems at all times while the vehicle is in
motion.
The use of infant or child restraints is required
by law in all 50 states, the District of

Columbia, the U.S. territories and all
Canadian provinces.
Infants and small children should always be
seated in an infant or child seat restraint
system appropriate for the size and weight of
the child. They must be properly secured in
accordance with the manufacturer's
installation instructions for the infant or child
seat restraint system. All infant and child seat
restraint systems must comply with the US
Federal Motor Vehicle Safety Standards 213
and 225 and Canadian Motor Vehicle Safety
Standards 213 and 210.2.
A statement by the child restraint
manufacturer of compliance with these
standards can be found on the instruction
label on the restraint system. You will also
find the statement in the instruction manual
provided with the child restraint system.
When using an infant restraint system, child
restraint system or booster seat, make sure
to carefully read and follow all manufacturer's
instructions for installation and use.
Please read the warning labels affixed to the
interior of the vehicle or to the infant restraint
or child restraint system.

G Warning

Accident statistics show that children
secured in the rear seats are safer than
children secured in the front-passenger seat.
For this reason, we strongly advise that you
always secure children in the rear seats.
Regardless of the seat position, children
under 12 years must be secured correctly in
a suitable infant or child restraint system or
booster seat suitable for the size and weight
of the child.
The infant or child restraint system must be
correctly secured using the vehicle's seat
belt, the seat belt and Top Tether belt or the
lower anchorages and the Top Tether belt in
complete accordance with the child seat
manufacturer's instructions.
Occupants, in particular children, must sit as

Children can be seriously or even fatally
injured by an air bag deploying. Observe the
following important information if it is
absolutely necessary to carry a child on the
front-passenger seat:
RUSA

only: Your vehicle is equipped with air
bag technology that is designed to
deactivate the front-passenger front air
bag, when the system on the frontpassenger seat detects the weight of a
typical 12-month old child in a standard
child restraint.
RUSA only: For children that weigh more
than a typical 12-month old child, the frontpassenger front air bag can be activated or
deactivated. Always make sure that the
45 indicator lamp is illuminated
indicating that the front-passenger front air
bag is deactivated.
RCanada only: Children 12 years old and
under may ride on the front seat if a
BabySmart™ compatible child restraint
system is installed on the front-passenger
seat. Use only Mercedes-Benz approved
BabySmart™ compatible child restraint
systems. A BabySmart™ compatible child
restraint system will deactivate the frontpassenger front air bag when installed
correctly. The front-passenger front air bag
will not be deactivated if the child restraint
systems that are installed are not
BabySmart™ compatible or if BabySmart™
compatible child restraint systems are not
installed correctly. If the front-passenger
front air bag is deployed in a collision, the
child could be struck by the air bag. This
could lead to serious or fatal injury.
RA child in a rear-facing child restraint on the
front-passenger seat will be seriously
injured or even killed if the front-passenger
front air bag inflates in a collision which
could occur under some circumstances,
even with the air bag technology installed
in your vehicle. The only way to completely

rule out this risk is by making sure you
never place a child in a rearward-facing
child restraint system on the frontpassenger seat. For this reason, we
strongly advise that you always carry
children in a rearward-facing child restraint
system on a rear seat.
RIf you must install a rear-facing child
restraint on the front-passenger seat
because circumstances require you to do
so, make sure the 45 indicator lamp
is illuminated, indicating that the frontpassenger front air bag is deactivated. If the
45 indicator lamp does not light up
or goes out when the child restraint system
is installed, check the anchorages of the
restraint system. Check the 45
indicator lamp regularly while driving to
ensure that the 45 indicator lamp is
illuminated. If the 45 indicator lamp
goes out or remains out, you may only carry
a child on the front-passenger seat once
the system has been repaired.
A child in a rear-facing child restraint on the
front-passenger seat will be seriously
injured or even killed if the front-passenger
front air bag inflates.
Rwhen securing a child in a child restraint
system on the front-passenger seat, you
must:
- move the front-passenger seat as far
back as possible
- use a child restraint system that is
suitable for the age, size and weight of
the child
- observe the manufacturer's installation
instructions in order to install and secure
the child restraint system correctly.

Overview of driving safety systems
In this section, you will find information about
the following driving safety systems:
RABS (Anti-lock Braking System)
RBAS (Brake Assist System)
RBAS PLUS (Brake Assist System Plus*)
RESP® (Electronic Stability Program)
REBD (Electronic Brake-power Distribution)
RADAPTIVE BRAKE
RPRE-SAFE® Brake (vehicles with
DISTRONIC PLUS)

Important safety notes
G Warning

The following factors increase the risk of
accidents:
RExcessive

speed, especially in turns
and slippery road surfaces
RFollowing another vehicle too closely
The driving safety systems described in this
section cannot reduce these risks or prevent
the natural laws of physics from acting on the
vehicle. They cannot increase braking or
steering efficiency beyond that afforded by
the condition of the vehicle brakes and tires
or the traction afforded.
RWet

Only a safe, attentive, and skillful driver can
prevent accidents.
The capabilities of a vehicle equipped with the
driving safety systems described in this
section must never be exploited in a reckless
or dangerous manner which could jeopardize
the user's safety or the safety of others.
Always adjust your driving style to the
prevailing road and weather conditions and
keep a safe distance to other road users and
objects on the street.
If a driving system malfunctions, other driving
safety systems may also switch off. Observe
indicator and warning lamps that may come
on as well as messages in the multifunction
display that may appear.

i In wintry driving conditions, always use
winter tires (M+S tires) and if necessary,
snow chains. Only in this way will the
driving safety systems described in this
section work as effectively as possible.

ABS (Anti-lock Braking System)
Important safety notes
G Warning

Observe "Important safety notes"
(Y page 65).

G Warning

Do not pump the brake pedal. Use firm, steady
brake pedal pressure instead. Pumping the
brake pedal defeats the purpose of the ABS
and significantly reduces braking
effectiveness.

ABS regulates brake pressure in such a way
that the wheels do not lock when you brake.
This allows you to continue steering the
vehicle when braking.
ABS works from a speed of about
5 mph (8 km/h) upwards, regardless of roadsurface conditions. ABS works on slippery
surfaces, even when you only brake gently.

Braking
If ABS intervenes when braking, you will feel
a pulsing in the brake pedal.
X If ABS intervenes: continue to depress the
brake pedal with force until the braking
situation is over.
X To make a full brake application:
depress the brake pedal with full force.

G Warning

If the ABS malfunctions, other driving systems
such as the BAS or the ESP® are also switched
off. Observe indicator and warning lamps that
may come on as well as messages in the
multifunction display that may appear.
If the ABS malfunctions, the wheels may lock
during hard braking, reducing the steering
capability and extending the braking distance.

The pulsating brake pedal can be an
indication of hazardous road conditions and
functions as a reminder to take extra care
while driving.

BAS (Brake Assist)
G Warning

Observe "Important safety notes"
(Y page 65).

BAS operates in emergency braking
situations. If you depress the brake pedal
quickly, BAS automatically boosts the braking
force, thus shortening the stopping distance.
X Keep the brake pedal firmly depressed until
the emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will function as usual once you
release the brake pedal. BAS is deactivated.

G Warning

If the BAS malfunctions, the brake system still
functions, but without the additional brake
boost available that the BAS would normally
provide in an emergency braking maneuver.
Therefore, the braking distance may increase.

BAS PLUS (Brake Assist PLUS)
G Warning

Observe "Important safety notes"
(Y page 65).

At speeds above approximately
20 mph (30 km/h), BAS PLUS assists you
when braking in hazardous situations and
uses the radar sensor system to evaluate the
traffic conditions.

G Warning!

BAS PLUS is a convenience system designed
to assist the driver during vehicle operation.
The responsibility for the vehicle speed and
the distance to the vehicle ahead, including
most importantly brake operation to assure
safe stopping distance, always remains with
the driver.
Always pay attention to traffic conditions
even while BAS PLUS is switched on.
Otherwise, you may not be able to recognize
dangerous situations until it is too late and
could cause an accident. Personal or fatal
injury to you or others may be the result.

i This equipment has been approved by the
FCC as a "Vehicular Radar System". The
radar sensor system is intended for use in
an automotive radar system only. Removal,
tampering, or altering of the device will void
any warranties, and is not permitted by the
FCC. Do not tamper with the device in any
way.
Any unauthorized modification to this
device could void the user's authority to
operate the equipment.

Version: 3.0.3.6

Driving safety systems
BAS PLUS can detect obstacles that are in the
path of your vehicle for an extended period of
time. Should you approach a detected
obstacle quickly, BAS PLUS calculates the
braking force necessary to avoid a rear-end
collision. Should you additionally apply the
brakes, BAS PLUS will automatically increase
the braking force to a level suitable for the
traffic conditions.
If BAS PLUS demands particularly high
braking force, PRE-SAFE® is activated
simultaneously.
X Keep the brake pedal depressed until the
emergency braking situation is over.
ABS prevents the wheels from locking.
The brakes will work normally again when:
release the brake pedal
obstacle is detected in front of your
vehicle
Rthere is no longer any danger of a rear-end
collision
BAS PLUS is then deactivated.
At speeds up to approximately
40 mph (70 km/h), BAS PLUS can also detect
stationary obstacles, for example, stopped or
parked vehicles.
For BAS PLUS to assist you when driving, the
radar sensor system must be switched on and
operational. You can check this by activating
DISTRONIC PLUS (Y page 179) or via the
"radar sensor" function in the on-board
computer(Y page 232).

PLUS will not react to persons, animals, and
approaching traffic or cross-traffic.
BAS PLUS may not detect narrow vehicles
driving in front of you, such as motorcycles
and vehicles driving offset from your vehicle
center.

Following a collision or accident-related
damage to the front end of the vehicle, have
the configuration and operation of the radar
sensors checked at an authorized MercedesBenz Center.
If BAS PLUS is not available due to a
malfunction in the radar sensor system, the
brake system remains available with full
brake boosting effect and BAS.

Important safety notes
G Warning

Observe "Important safety notes"
(Y page 65).

If ESP® detects that the vehicle is deviating
from the direction desired by the driver, one
or more wheels are braked to stabilize the
vehicle. If necessary, the engine output is also
modified to keep the vehicle on the desired
course within physical limits. ESP® assists
the driver when pulling away on wet or
slippery roads. ESP® can also stabilize the
vehicle during braking.
If ESP® intervenes, the ä warning lamp

Never switch off the ESP when you see the
ESP warning lamp ä flashing in the
instrument cluster. In this case proceed as
follows:
RWhen

driving off, apply as little throttle as
possible.
RWhile driving, ease up on the accelerator
pedal.
RAdapt your speed and driving style to the
prevailing road conditions.
Failure to observe these guidelines could
cause the vehicle to skid. The ESP cannot
prevent accidents resulting from excessive
speed.

! Vehicles without 4MATIC: switch the
ignition off when:
Rthe parking brake is being tested using a

dynamometer
Rthe vehicle is being towed with the front/

rear axle raised
Application of the brakes by ESP® may
otherwise destroy the brake system.

! Vehicles with 4MATIC: switch off the
ignition when the parking brake is being
tested on a brake dynamometer.
Application of the brakes by ESP® may
otherwise destroy the brake system.

i Only use wheels with the recommended
tire sizes. Only then will ESP® function
properly.

ETS/4ETS (Electronic Traction System)
G Warning

Observe "Important safety notes"
(Y page 65).

Traction control is part of ESP®.
Traction control brakes the drive wheels
individually if they spin. This enables you to
pull away and accelerate on slippery surfaces,
for example if the road surface is slippery on

one side. On vehicles with 4MATIC, more
drive torque is also transferred to the wheel
or wheels with traction.
Traction control remains active if you
deactivate ESP®.

Deactivating/activating ESP® (except
AMG vehicles)
G Warning!

The ESP should not be switched off during
normal driving other than in the
circumstances described below. Disabling
the system will reduce vehicle stability in
driving maneuvers.
Do not switch off the ESP when a spare wheel
is mounted.

ESP® is activated automatically when the
engine is running.
It may be best to deactivate ESP® in the
following situations:
Rwhen

PRE-SAFE® Brake (vehicles with
DISTRONIC PLUS)
PRE-SAFE® Brake can help you to minimize
the risk of a frontal collision with a vehicle
ahead or reduce the effects of such a
collision.
This function warns you from a speed of
approximately 20 mph (30 km/h) when you
are rapidly approaching a vehicle in front. An
intermittent warning tone sounds and the
· distance warning lamp lights up in the
instrument cluster.
Due to the nature of the system, particularly
complicated driving conditions may cause the
system to display an unnecessary warning.
At speeds of above approximately
20 mph (30 km/h), if the driver and

indicate that the PRE-SAFE® Brake will not be
capable of slowing the vehicle sufficiently to
maintain the preset following distance, which
creates a danger of a collision.
Immediately brake your vehicle to increase
the distance between your vehicle and the
vehicle driving in front of you. The warning
sound is intended as a final caution that you
have not interceded with your own braking
inputs to avoid a potentially dangerous
situation. Do not wait for the operation of the
warning signal to intercede with your own
braking, as that will result in potentially
dangerous emergency braking which will not
always result in an impact being avoided.
Tailgating increases the risk of an accident.

G Warning!

The PRE-SAFE® Brake is a convenience
system designed to assist the driver during
vehicle operation. The responsibility for the
vehicle speed and the distance to the vehicle
ahead, including most importantly brake
operation to assure safe stopping distance,
always remains with the driver.
Always pay attention to traffic conditions
even while the PRE-SAFE® Brake is switched
on. Otherwise, you may not be able to
recognize dangerous situations until it is too
late and could cause an accident resulting in
personal or fatal injury to you or others.

With the help of the radar sensor system,
PRE-SAFE® Brake can detect obstacles that
are in front of your vehicle for an extended
period of time. If you approach an obstacle
and PRE-SAFE® Brake detects a risk of a
collision, the system will initially alert you
both visually and acoustically. If you do not
brake or steer, the vehicle will at first
automatically brake slightly. In the event of
an increased risk of a collision, PRE-SAFE® is
activated (Y page 51). If the risk of collision
remains and you do not brake, take evasive
action or accelerate significantly, the vehicle
may perform automatic emergency braking.

G Warning!

The PRE-SAFE® Brake will only respond with
brake assistance if it has clearly detected an
object. Detection can be impeded by:
Rdirty

or covered sensors
or heavy rain
Rdisturbance from other radar sources
Rstrong radar reflection such as in parking
garages
Rsnowfall

The PRE-SAFE® Brake uses radar signals that
are not reflected well by narrow objects and
absorptive materials. For this reason the PRESAFE® Brake will not react to persons,
animals, and approaching traffic or crosstraffic.
The PRE-SAFE® Brake may not detect narrow
vehicles driving in front of you, such as

G Warning

Depending on the vehicle speed, PRE-SAFE®
Brake brakes your vehicle with a maximum of
13 ft/s2 (4 m/s2) before a possible hard stop.
This corresponds to about 40 % of the
maximum deceleration ability of your vehicle.
The driver must apply the brakes additionally
in order to prevent a collision. The self-acting
hard stop will be initiated when the imminent
danger of a collision exists, e.g. when an
evasive maneuver cannot avoid an accident.

In order to maintain the appropriate distance
to the vehicle in front and thus prevent a
collision, you must apply the brakes yourself.
At speeds up to approximately
40 mph (70 km/h), PRE-SAFE® Brake can
also detect stationary obstacles, for example
stopped or parked vehicles.

Important safety notes
When leaving the vehicle, always remove the
SmartKey from the starter switch. Always
take the SmartKey with you and lock the
vehicle. Do not leave children unattended in
the vehicle, even if they are secured in a child
restraint system, or with access to an
unlocked vehicle. A child's unsupervised
access to a vehicle could result in an accident
and/or serious personal injury. The children
could
Rinjure

themselves on parts of the vehicle
seriously or fatally injured through
excessive exposure to extreme heat or cold
Rinjure themselves or cause an accident with
vehicle equipment that can be operated
even if the SmartKey is removed from the
starter switch or removed from the vehicle,
such as seat adjustment, steering wheel
adjustment, or the memory function
If children open a door, they could injure other
persons or get out of the vehicle and injure
themselves or be injured by following traffic.
Do not expose the child restraint system to
direct sunlight. The child restraint system's
metal parts, for example, could become very
hot, and the child could be burned by these
parts.

Important safety notes
G Warning

In order to avoid possible loss of vehicle
control, all seat, head restraint, steering
wheel and rear view mirror adjustments, as
well as fastening of seat belts, must be done
before setting the vehicle in motion.

G Warning

Do not adjust the driver's seat while driving.
Adjusting the seat while driving could cause
the driver to lose control of the vehicle.
Never travel in a moving vehicle with the seat
backrest in an excessively reclined position as
this can be dangerous. You could slide under
the seat belt in a collision. If you slide under
it, the seat belt would apply force at the
abdomen or neck. This could cause serious or
fatal injuries. The seat backrest and seat belts
provide the best restraint when the wearer is
in a position that is as upright as possible and
seat belts are properly positioned on the
body.

G Warning

Your seat belt must be adjusted so that you
can correctly fasten your seat belt.
Observe the following points:
Radjust the seat backrest until your arms are

slightly angled when holding the steering
wheel.
Radjust the seat to a comfortable seating
position that still allows you to reach the
accelerator/brake pedal safely. The
position should be as far back as possible
with the driver still able to operate the
controls properly.
Radjust the head restraint so that it is as
close to the head as possible and the center

103

of the head restraint supports the back of
the head at eye level.
Rnever place hands under the seat or near
any moving parts while a seat is being
adjusted.
Failure to do so could result in an accident
and/or serious personal injury.

G Warning

The electrically adjustable seats can be
operated at any time. Therefore, do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. A child's
unsupervised access to a vehicle could result
in an accident and/or serious personal injury.

G Warning!

According to accident statistics, children are
safer when properly restrained in the rear
seating positions than in the front seating
position. Thus, we strongly recommend that
children be placed in the rear seats whenever
possible. Regardless of seating position,
children 12 years old and under must be
seated and properly secured in an
appropriately sized infant restraint, toddler
restraint, or booster seat recommended for
the size and weight of the child. For additional
information, see "Children in the vehicle".
A child's risk of serious or fatal injuries is
significantly increased if the child restraints
are not properly secured in the vehicle and/
or the child is not properly secured in the child
restraint.

G Warning

For your protection, drive only with properly
positioned head restraints.
Adjust the head restraint so that it is as close
to the head as possible and the center of the
head restraint supports the back of the head
at eye level. This will reduce the potential for
injury to the head and neck in the event of an
accident or similar situation.

Important safety notes
For reasons of safety, Mercedes-Benz
recommends that you drive with the lights
switched on even during the daytime. In some
countries, operation of the headlamps varies
due to legal requirements and self-imposed
obligations. In these countries, the daytime
running lamps are automatically switched on
when the engine is started.

Notes on driving abroad
Converting to symmetrical low beam
when driving abroad: switch the headlamps
to symmetrical low beam in countries in
which traffic drives on the opposite side of the
road to the country where the vehicle is
registered. This prevents oncoming traffic
from being dazzled. Symmetrical lights do not
illuminate as large an area of the edge of the
road.
Have the headlamps converted at a qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center, as close to the border
as possible before driving in these countries.
Converting to asymmetrical low beam
after returning: have the headlamps
converted back to asymmetrical low beam at
a qualified specialist workshop, e.g. an
authorized Mercedes-Benz Center, as soon as
possible after crossing the border when
returning.

Important safety notes
Xenon bulbs
If your vehicle is equipped with Xenon bulbs,
you can recognize this by the following: the
cone of light from the Xenon bulbs moves
from the top to the bottom and back again
when you start the engine. For this to be
observed, the lights must be switched on
before starting the engine.

G Warning!

Xenon bulbs carry a high voltage. You could
get an electric shock and be seriously or even
fatally injured if you touch the electric
contacts on Xenon bulbs. Therefore, never
remove the cover from Xenon bulbs.
Do not change Xenon bulbs yourself, but have
them replaced at a qualified specialist
workshop which has the necessary specialist
knowledge and tools to carry out the work
required.
Mercedes-Benz recommends that you use an
authorized Mercedes-Benz Center for this
purpose. In particular, work relevant to safety
or on safety-related systems must be carried
out at a qualified specialist workshop.

Bulbs and lamps are an important aspect of
vehicle safety. You must therefore make sure
that these function correctly at all times.
Have the headlamp setting checked regularly.

Other bulbs
Crash-responsive emergency lighting
If the interior lighting is set to automatic, the
interior lighting is activated automatically if
the vehicle is involved in an accident.
X To switch off the crash-responsive
emergency lighting: press the hazard
warning lamp button.
or
X Lock and then unlock the vehicle using the
key.

G Warning!

Bulbs and lamps can be very hot. You should
therefore allow them to cool down before you
change them. Otherwise, you could be burned
if you touch them.
Keep bulbs out of the reach of children.
Otherwise, they could damage the bulbs, for
example, and injure themselves.

G Warning!

Wiper blades are components that are subject
to wear and tear. Replace the wiper blades
twice a year, preferably in the spring and fall.
Otherwise the windows will not be wiped
properly. As a result, you may not be able to
observe surrounding traffic conditions and
could cause an accident.

! Do not operate the windshield wipers
when the windshield is dry, as this could
damage the wiper blades. Moreover, dust
that has collected on the windshield/rear
window can scratch the glass if wiping
takes place when the windshield/rear
window is dry.
If it is necessary to switch on the windshield
wipers in dry weather conditions, always
use washer fluid when operating the
windshield wipers.

G Warning

Severe conditions (e.g. strong air pollution)
may require replacement of the filter before
its scheduled replacement interval. A clogged
filter will reduce the air volume to the interior
and the windows could fog up, impairing
visibility and endangering you and others.
Have a clogged filter replaced as soon as
possible at an authorized Mercedes-Benz
Center.

i Ventilate the vehicle for a brief period
during warm weather, e.g. using the
convenience opening feature (Y page 93).
This will speed up the cooling process and
the desired vehicle interior temperature
will be reached more quickly.

i The integrated filter can filter out most
particles of dust and completely filters out
pollen. A clogged filter reduces the amount
of air supplied to the vehicle interior. For
this reason, you should always observe the
interval for replacing the filter, which is
specified in the Service Booklet. As it
depends on environmental conditions, e.g.
heavy air pollution, the interval may be
shorter than stated in the Service Booklet.

i It is possible that the "residual heat"
function may be activated automatically an
hour after the SmartKey is removed. The
vehicle is then ventilated for 30 minutes to
dry the air-conditioning system.

G Warning

Follow the recommended settings for heating
and cooling given on the following pages.
Otherwise, the windows could fog up,
impairing visibility and endangering you and
others.

Dual-zone automatic climate control/3-zone
automatic climate control controls the
temperature and the humidity of the vehicle
interior and filters out undesirable
substances from the air.
Dual-zone automatic climate control/3-zone

The cooling with air dehumidification function
is only available when the engine is running.
The air inside the vehicle is cooled and
dehumidified according to the temperature
selected.

G Warning

If you switch off the cooling function, the
vehicle will not be cooled when weather
conditions are warm. The windows can fog up
more quickly. Window fogging may impair
visibility and endanger you and others.

Condensation may drip from the underside of
the vehicle when automatic climate control is
in cooling mode. This is normal and not a sign
that there is a malfunction.

i The cooling with air dehumidification
function uses refrigerant R134a. This
coolant does not contain
chlorofluorocarbons, and therefore does
not damage the ozone layer.

and optional equipment of your vehicle
which was available at the time of
purchase. Country-specific differences are
possible. Bear in mind that your vehicle
may not feature all functions described
here. This also refers to safety-related
systems and functions.

Notes on breaking-in a new vehicle
The first 1000 miles (1500 km)
The more you look after the engine when it is
new, the happier you will be with its
performance in the future.
RDrive

at varying vehicle speeds and engine
speeds for the first 1000 miles (1500 km)
for this reason.
RAvoid overstraining the vehicle during this
period, e.g. driving at full throttle.
RChange gear in good time, at the latest
when the tachometer needle is 2/3 of the
way to the red area in the tachometer
display.
RIf possible, do not depress the accelerator
pedal past the point of resistance
(kickdown).
ROnly select shift ranges 3, 2 or 1 when
driving slowly, e.g. in mountainous terrain.
After 1000 miles (1500 km) you may
gradually bring the vehicle up to full road and
engine speeds.
Additional breaking-in notes for AMG
vehicles:
RFor

the first 1000 miles (1500 km), do not
exceed a speed of 85 mph (140 km/h).
ROnly allow the engine to briefly reach a
maximum engine speed of 4500 rpm.
RShift gears in good time.

i Also observe these breaking-in notes
when the vehicle's engine or axle gear have
been replaced.

i Always observe the respective limit
speeds.

AMG vehicles with rear axle locking
differential
Your vehicle is equipped with a self-locking
differential on the rear axle. Change the oil
after a breaking-in period of
2000 miles(3000 km) to improve protection
of the rear axle differential. This oil change
extends the service life of the differential.
Have the oil change carried out at a qualified
specialist workshop. Mercedes-Benz
recommends that you use an authorized
Mercedes-Benz Center for this purpose.

Driving
Important safety notes
G Warning

Make sure absolutely no objects are
obstructing the pedals' range of movement.
Keep the driver's footwell clear of all
obstacles. If there are any floormats or
carpets in the footwell, make sure the pedals
still have sufficient clearance.
During sudden driving or braking maneuvers
the objects could get caught between the
pedals. You could then no longer brake or
accelerate. This could lead to accidents and
injury.

G Warning

On slippery road surfaces, never downshift in
order to obtain braking action. This could
result in drive wheel slip and reduced vehicle
control. Your vehicle's ABS will not prevent
this type of loss of control.

2010-05-20T13:33:46+02:00 - Seite 149

Driving
G Warning

It is dangerous to shift the automatic
transmission out of parking position P or
neutral position N if the engine speed is
higher than idle speed. If your foot is not firmly
on the brake pedal, the vehicle could
accelerate quickly forward or in reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and when
your right foot is firmly on the brake pedal.

! Warm up the engine quickly. Do not use
the engine's full performance until it has
reached operating temperature.
Only shift the automatic transmission to
the desired drive position when the vehicle
is stationary.
Where possible, avoid spinning the drive
wheels when pulling away on slippery
roads. You could otherwise damage the
drive train.

! AMG vehicles: at low engine oil
temperatures (below 68 ‡ (+20 †), the
maximum engine speed is restricted in
order to protect the engine. To protect the
engine and maintain smooth engine
operation, avoid driving at full throttle when
the engine is cold.

Refueling
Important safety notes
G Warning!

Gasoline and diesel fuels are highly flammable
and poisonous. They burn violently and can
cause serious injury.
Never allow sparks, flames or smoking
materials near gasoline or diesel fuel!
Turn off the engine before refueling.
Whenever you are around gasoline or diesel
fuel, avoid inhaling fumes and any skin or
clothing contact. Extinguish all smoking
materials.
Direct skin contact with fuels and the
inhalation of fuel vapors are damaging your
health.

G Warning

Overfilling of the fuel tank may create
pressure in the system which could cause a
gas discharge. This could cause the gasoline
to spray back out when removing the fuel
pump nozzle, which could cause personal
injury.

Refueling
G Warning!

Do not fill diesel tanks with gasoline. Do not
mix diesel fuel with gasoline. Otherwise the
fuel system and engine could be damaged. In
addition, the vehicle could catch fire.

! Do not use gasoline to refuel vehicles with
a diesel engine. Do not use diesel to refuel
vehicles with a gasoline engine. Even small
amounts of the wrong fuel result in damage
to the fuel system and engine.

! Do not switch on the ignition if you
accidentally refuel with the wrong fuel.
Otherwise, the fuel will enter the fuel lines.
Notify a qualified specialist workshop and
have the fuel tank and fuel lines drained
completely.

Gasoline
Fuel grade
! You should only refuel with unleaded
premium-grade gasoline as this avoids
damaging the catalytic converter.
If engine running problems are apparent,
have the cause checked immediately and
repaired. Excess unburned fuel can
otherwise enter the catalytic converter,
leading to overheating and possibly
causing a fire.

i Only refuel with unleaded premium-grade
gasoline with a specified minimum octane
number of 91 (average value of 96 RON/
86 MON).
Usually you will find information about the
fuel grade on the pump. If you cannot find
the label on the gasoline pump, ask the gas
station staff.
You can find further information under
"Fuel" (Y page 388), by consulting an
authorized Mercedes-Benz Center or
visiting http://www.mbusa.com (USA
only).

Diesel
Fuel grade
! Only refuel with ULTRA-LOW SULFUR
DIESEL FUEL (ULSD, 15 ppm SULFUR
MAXIMUM). Using other diesel fuels could
result in increased wear and damage to the
engine and/or exhaust system.
Never refuel with marine diesel or heating
oil.
Do not mix these fuels with diesel fuels and
do not use any special additives, as this
may result in damage.

! Use a filter when adding fuel from a fuel
can. Otherwise, the fuel lines and/or the
fuel injection system could be blocked by
particles from the fuel can.

i Refuel only with ULTRA-LOW SULFUR
HIGHWAY DIESEL FUEL (ULSD, 15 ppm
SULFUR MAXIMUM).
Usually you will find information about the
fuel grade on the pump. If you cannot find

Low outside temperatures
! Do not use gasoline to refuel vehicles with
a diesel engine. Never mix diesel with
gasoline or kerosene, as this may result in
damage to the engine or fuel system.
Diesel fuel with improved cold flow properties
is available during the winter months. Further
information on fuel properties can be
obtained from oil companies, e.g. at filling

To save fuel, observe the following notes:
X

Driving and parking

2010-05-20T13:33:46+02:00 - Seite 172
Version: 3.0.3.6

Keep tires at the recommended inflation
pressures.
X Remove unnecessary cargo.
X Remove the roof rack when not in use.
X Maintain a low engine speed until the
engine is warm.
X Avoid frequent acceleration and
deceleration.
X Have all maintenance work performed at
the service intervals specified in the
Service Booklet or indicated by the service
interval indicator.
Fuel consumption is also increased by driving
in cold weather, in stop-and-go traffic, on
short trips and in mountainous areas.

Drinking and driving
G Warning

Drinking and driving and/or taking drugs and
driving are very dangerous combinations.
Even a small amount of alcohol or drugs can
affect your reflexes, perceptions and
judgment.
The possibility of a serious or even fatal
accident are greatly increased when you drink
or take drugs and drive.
Do not drink or take drugs and drive or allow
anyone to drive who has been drinking or
taking drugs.

Pedals
G Warning

Make sure absolutely no objects are
obstructing the pedals' range of movement.
Keep the driver's footwell clear of all
obstacles. If there are any floormats or
carpets in the footwell, make sure that the
pedals still have sufficient clearance.
During sudden driving or braking maneuvers,
the objects could get caught between the
pedals. You could then no longer brake or

accelerate. This could lead to accidents and
injury.

Coasting with the engine switched off
G Warning!

There is no power assistance for the steering
and the brake when the engine is not running.
Steering and braking requires significantly
more effort and you could lose control of the
vehicle and cause an accident as a result.
Do not turn off the engine while the vehicle is
in motion.

Exhaust check
G Warning

Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon
monoxide (CO), and inhaling it can cause
unconsciousness and possible death.
Do not run the engine in confined areas (such
as a garage) which are not properly ventilated.
If you think that exhaust gas fumes are
entering the vehicle while driving, have the
cause determined and corrected
immediately. If you must drive under these
conditions, drive only with at least one
window fully open at all times.

Certain engine systems are designed to keep
the level of poisonous components in exhaust
fumes within legal limits.
These systems only work optimally if they are
maintained exactly in accordance with the
manufacturer's specifications. For this
reason, all work on the engine must be carried
out by qualified and authorized MercedesBenz technicians.
The engine settings must not be changed in
any circumstances. Furthermore, all specific
service work must be carried out at regular
intervals and in accordance with the
Mercedes-Benz service requirements. Details
can be found in the Service Booklet.

Driving tips
Engine oil
! Vehicles with a diesel particle filter:
If the vehicle is mostly driven for short
distances, it is possible that malfunctions
may occur during the automatic cleaning of
the diesel particle filter. This can lead to
engine damage. Therefore, if you frequently
drive short distances, make sure to drive
on highways or inter-urban roads for 20
minutes at least every 310 miles (500 km).

Brakes
Important safety notes
G Warning

On slippery road surfaces, never downshift in
order to obtain braking action. This could
result in drive wheel slip and reduced vehicle
control. Your vehicle's ABS will not prevent
this type of loss of control.

G Warning

Make sure that you do not endanger other
road users when you apply the brakes.

Downhill gradients
! On long and steep gradients, you must
reduce the cargo on the brakes by shifting
to a lower gear in good time. This allows
you to take advantage of engine braking
and helps you to avoid overheating the
brakes and wearing them out excessively.
When you take advantage of engine
braking, a drive wheel may not turn for
some time, e.g. on a slippery road surface.
This could cause damage to the drive train.
Such damage is not covered by the
Mercedes-Benz warranty.

173

Heavy and light loads
G Warning

Depressing the brake pedal constantly results
in excessive and premature wear to the brake
pads.
It may also cause the brakes to overheat,
seriously impairing their effectiveness. It may
then not be possible to stop the vehicle in
sufficient time to avoid an accident.

If the brakes have been subjected to a heavy
cargo, do not stop the vehicle immediately,
but drive on for a short while. This allows the
airflow to cool the brakes more quickly.

Wet roads
G Warning

After driving in heavy rain for some time
without applying the brakes or through water
deep enough to wet brake components, the
first braking action may be somewhat
reduced. You have to depress the brake pedal
more firmly. Maintain a safe distance from
vehicles in front.

After driving on a wet road or having the
vehicle washed, brake firmly while paying
attention to the traffic conditions. This will
warm up the brake discs, thereby drying them
more quickly and protecting them against
corrosion.

Limited braking performance on salt
treated roads
G Warning

The layer of salt on the brake discs and the
brake pads/linings may cause a delay in the
braking effect, resulting in a significantly
longer braking distance, which could lead to
an accident.
To avoid this danger, you should:
Roccasionally brake carefully, without
putting other road users at risk, when you
are driving on salted roads. This helps to

trip and immediately after commencing a
new trip, so that salt residues are removed
from the brake discs.

Servicing the brakes
! If the red brake warning lamp lights up in
the instrument cluster and you hear a
warning tone while the engine is running,
the brake fluid level may be too low.
Observe additional warning messages in
the multifunction display.
The brake fluid level may be too low due to
brake pad wear or leaking brake lines.
Have the brake system checked
immediately. This work should be carried
out at an authorized Mercedes-Benz
Center.
All checks and maintenance work on the
brake system must be carried out at a
qualified specialist workshop. This work
should be carried out at an authorized
Mercedes-Benz Center.
Only install brake pads and use brake fluid
recommended by Mercedes-Benz.

G Warning

If other than recommended brake pads are
installed, or other than recommended brake
fluid is used, the braking properties of the
vehicle can be degraded to an extent that safe
braking is substantially impaired. This could
result in an accident.

! Vehicles with 4MATIC: a function or

performance test may only be carried out
on a two-axle dynamometer. If you are
planning to have the vehicle tested on such
a dynamometer, contact an authorized
Mercedes-Benz Center to obtain further

information first. Otherwise, the drive train
or the brake system may suffer damage.

! Vehicles with 4MATIC: as the ESP®

system operates automatically, the engine
and the ignition must be switched off
(SmartKey in position 0 or 1 in the ignition
lock or Start/Stop button in position 0 or
1) while the parking brake is being tested

Driving tips
G Warning

New vehicle brake pads and discs, and
replacement brake pads and discs may take
several hundred miles of driving until they
provide optimum braking efficiency. Until that
time, you may need to use increased brake
pedal pressure while braking. Please be aware
of this and adjust your driving and braking
accordingly during this break-in period.
Excessive high-demand braking will cause
correspondingly high brake wear. Please be
attentive to the brake warning lamp in the
instrument cluster and brake condition
messages in the multifunction display.
Especially for high performance driving, it is
important to maintain and have the brake
system checked regularly.

The wear of individual components of the
brake system, such as the brake pads/linings
or brake discs, depends on the individual
driving style and operating conditions.

Driving on wet roads
Hydroplaning
If water has accumulated to a certain depth
on the road surface, there is a danger of
hydroplaning occurring, even if:

Driving on flooded roads
! Do not drive through flooded areas.
Check the depth of any water before driving
through it. Drive slowly through standing
water. Otherwise, water may enter the
vehicle interior or the engine compartment.

This can damage the electronic
components in the engine or the automatic
transmission. Water can also be drawn in
by the engine's air suction nozzles and this
can cause engine damage.

Winter driving
General information
Have your vehicle winterproofed at a qualified
specialist workshop, e.g. at an authorized
Mercedes-Benz Center, at the onset of
winter.
Observe the notes in the "Winter operation"
section (Y page 176).

i Vehicles with a diesel engine: do not
cover the radiator, e.g. with a protective
cover. The measuring function of the
Onboard Diagnosis System may otherwise
provide inaccurate values. Some of these
values are required by law and must
therefore always be accurate.

Winter tires
At temperatures below 45 ‡(+7 †), use
winter tires or all-season tires. Both types of
tire are identified by the M+S marking.
Only winter tires also bearing the i
snowflake symbol next to the M+S marking
provide the best possible grip in wintry road
conditions. Only these tires will allow driving
safety systems such as ABS and ESP® to
function optimally in winter, as these tires
have been designed specifically for driving on
snow.
Use M+S tires of the same make and tread on
all wheels to maintain safe handling
characteristics.

G Warning

M+S tires with a tread depth of less than 1/6
inch (4 mm) must be replaced. They are no
longer suitable for winter operation.

G Warning!

The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the
freezing point do not guarantee that the road
surface is free of ice. The road may still be icy,
especially in wooded areas or on bridges.

G Warning

On slippery road surfaces, never downshift in
order to obtain braking action. This could
result in drive wheel slip and reduced vehicle
control. Your vehicle's ABS will not prevent
this type of loss of control.

You should drive particularly carefully on
slippery road surfaces. Avoid sudden
acceleration, steering and braking
maneuvers. Do not use cruise control or
DISTRONIC PLUS.

Cruise control
Important safety notes
Cruise control maintains a constant road
speed for you. It brakes automatically in order
to avoid exceeding the set speed. On long and
steep downhill gradients, especially if the
vehicle is laden, you must select shift range
1, 2 or 3 in good time. By doing so, you will
make use of the braking effect of the engine,
which relieves the load on the brake system
and prevents the brakes from overheating
and wearing too quickly.
Use cruise control only if road and traffic
conditions make it appropriate to maintain a
steady speed for a prolonged period. You can
store any road speed above 20 mph
(30 km/h).

G Warning

The cruise control is a convenience system
designed to assist the driver during vehicle
operation. The driver is and must always
remain responsible for the vehicle's speed
and for safe brake operation.
Only use the cruise control if the road, traffic,
and weather conditions make it advisable to
travel at a constant speed.
RThe use of the cruise control can be
dangerous on winding roads or in heavy
traffic because conditions do not allow safe
driving at a constant speed.
RThe use of the cruise control can be
dangerous on slippery roads. Rapid
changes in tire traction can result in wheel
spin and loss of control.
RDeactivate the cruise control when driving
in fog.
The "Resume" function should only be
operated if the driver is fully aware of the
previously set speed and wishes to resume
this particular preset speed.

DISTRONIC PLUS
Important safety notes
DISTRONIC PLUS regulates the vehicle's
speed and automatically helps you maintain
the distance to the vehicle detected in front.
It brakes automatically in order to avoid
exceeding the set speed.
On long and steep downhill gradients,
especially if the vehicle is laden, you must
select shift range 1, 2 or 3 in good time. By
doing so, you will make use of the braking
effect of the engine, which relieves the load
on the brake system and prevents the brakes
from overheating and wearing too quickly.
If a slower-moving vehicle is detected in front,
DISTRONIC PLUS causes your vehicle to
brake and maintain a preset distance to the
vehicle in front.

G Warning!

Deactivating cruise control

The DISTRONIC PLUS requires familiarity with
its operational characteristics. We strongly
recommend that you review the following
information carefully before operating the
system.

There are several ways to deactivate cruise

The DISTRONIC PLUS is a convenience
system. Its speed adjustment reduction
capability is intended to make cruise control
more effective and usable when traffic speeds
vary. It is not however, intended to, nor does
it, replace the need for extreme care.
The responsibility for the vehicle's speed,
distance to the preceding vehicle and, most
importantly, brake operation to ensure a safe
stopping distance, always remains with the
driver.
The DISTRONIC PLUS cannot take street and
traffic conditions into account.

Driving systems
If you want DISTRONIC PLUS to assist you,
the radar sensor system must be activated
(Y page 232) and operational.
If there is no vehicle in front, DISTRONIC
PLUS operates in the same way as cruise
control in the speed range between
20 mph (Canada: 30 km/h) and
120 mph (Canada: 200 km/h). If there is a
vehicle in front, DISTRONIC PLUS is
operational in the speed range between
0 mph (Canada: 0 km/h) and
120 mph (Canada: 200 km/h).
Do not use DISTRONIC PLUS while driving on
roads with steep gradients.
As DISTRONIC PLUS emits radar waves, it can
simulate radar detectors used by police
authorities. You can refer to the applicable
section in the Operator's Manual if there are
any questions concerning this.

It is the driver's responsibility at all times to
be attentive to the road, weather and traffic
conditions. Additionally, the driver must
provide the steering, braking and other driving
inputs necessary to remain in control of the
vehicle.
High-frequency sources such as toll stations,
speed measuring systems etc. can cause the
DISTRONIC PLUS system to temporarily
cease functioning.

i USA only:

Use of the DISTRONIC PLUS can be
dangerous on slippery roads. Rapid changes
in tire traction can result in wheel spin and
loss of control.
The DISTRONIC PLUS does not function in
adverse sight and distance conditions. Do not
use the DISTRONIC PLUS during conditions of
fog, heavy rain, snow or sleet.

This device has been approved by the FCC
as a “Vehicular Radar System”. The radar
sensor is intended for use in an automotive
radar system only. Removing, tampering
with, or altering the device will void any
warranties, and is not permitted by the
FCC. Do not tamper with, alter, or use in
any non-approved way.
Any unauthorized modification to this
device could void the user’s authority to
operate the equipment.

G Warning!

The DISTRONIC PLUS adaptive cruise control
is not a substitute for active driving
involvement. It does not react to pedestrians
or on stationary objects, nor does it recognize
or predict the curvature and lane layout or the
movement of preceding vehicles. The
DISTRONIC PLUS can only apply a maximum
of 40% of the vehicle's braking power.
The DISTRONIC PLUS may not detect narrow
vehicles possibly driving in front of you, such
as motorcycles and vehicles driving in an
offset formation.

G Warning!

The DISTRONIC PLUS cannot take road and
traffic conditions into account. Only use the
DISTRONIC PLUS if the road, weather and
traffic conditions make it advisable to travel
at a constant speed.

G Warning!

G Warning!

The DISTRONIC PLUS cannot take weather
conditions into account. Switch off the
DISTRONIC PLUS or do not switch it on if:
Rroads

are slippery or covered with snow or
ice. The wheels could lose traction while

could skid.
Rthe DISTRONIC PLUS system sensor covers
are dirty or visibility is diminished due to

you and/or others could be injured.

G Warning!

The "Resume" function should only be
operated if the driver is fully aware of the
previously set speed and wishes to resume
this particular preset speed.

G Warning

Your undivided attention to street and traffic
conditions is necessary at all times whether
DISTRONIC PLUS is active or not.
The use of DISTRONIC PLUS can be
dangerous on winding roads or in heavy traffic
because conditions do not allow safe driving
at a constant speed.
DISTRONIC PLUS does not react to stationary
objects on the road (for example, a vehicle
stopped in traffic or an abandoned vehicle).
DISTRONIC PLUS likewise does not react to
oncoming vehicles.
Deactivate DISTRONIC PLUS:
Rwhen

changing to the right lane, if the
vehicles in the left lane are driving slower
Rwhen driving into a filter lane or an
expressway exit
Rin complex driving situations, for example
at roadworks on an expressway
In these situations DISTRONIC PLUS will

DISTRONIC PLUS is intended only for
maintaining a set speed and a set distance
from the objects moving in front of the
vehicle.

distance, which creates a danger of a
collision.
Immediately brake the vehicle to increase
your distance to the preceding vehicle. The
warning sound is intended as a final caution
in which you should intercede with your own
braking inputs to avoid a potentially
dangerous situation. Do not wait for the
operation of the warning signal to intercede
with your own braking. This will result in
potentially dangerous emergency braking
which will not always result in an impact being
avoided.
Tailgating increases the risk of an accident.

G Warning

DISTRONIC PLUS brakes your vehicle with a
maximum deceleration of 13 ft/s(4 m/s2).
This corresponds to approximately 40% of
your vehicle's maximum possible braking
power.
You must apply the brakes yourself to avoid a
collision. DISTRONIC PLUS brakes the vehicle
to restore the set distance to the vehicle in
front or to restore the set speed.

G Warning!

If you do not receive visual or acoustic
warning signals during a critical traffic
situation, DISTRONIC PLUS has either not
recognized the collision risk, has been
deactivated or is malfunctioning.
Remember, whether or not DISTRONIC PLUS
is operating, it is ultimately always the drivers
responsibility to apply the brakes in order to
control the vehicle and avoid a collision.

G Warning!

An intermittent warning sounds and the

Tips for driving with DISTRONIC PLUS
Important safety guidelines
The following contains descriptions of certain
road and traffic conditions in which you must
be particularly attentive. In such situations,

G Warning!

The DISTRONIC PLUS works to maintain the
speed selected by the driver unless a moving
obstacle proceeding directly ahead of it in the
same travel direction is detected (e.g.
following another vehicle ahead of you at your
set distance).
This means that:

The ability of DISTRONIC PLUS to detect
vehicles when cornering is limited. Your
vehicle may brake unexpectedly or late.
Vehicles traveling on a different line

RYour vehicle can pass another vehicle after

you have changed lanes.
in a sharp turn or if the preceding
vehicle is in a sharp turn, the DISTRONIC
PLUS could lose sight of the preceding
vehicle. Your vehicle could then accelerate
to the previously selected speed.
The DISTRONIC PLUS regulates only the
distance between your vehicle and those

Parking Guidance
Important safety notes
Parking Guidance is an electronic parking aid
with ultrasound. Ultrasound is used to
measure the road on both sides of the vehicle.
A suitable parking space is indicated by the
parking symbol. You receive steering
instructions when parking. You may also use
PARKTRONIC (Y page 194).

display parking spaces that are not suitable
for parking, for example:
Rno-parking

and exits
Parking Guidance detects and measures
potential parking spaces while driving past.
Changes to the parking space after this point
are not taken into account, for example if the
vehicle in front of or behind the parking space
changes position or objects in the parking
space are moved.
Even when using Parking Guidance, you are
still responsible for driving carefully. If you
rely on Parking Guidance alone, you could
cause an accident and injure yourself and
others.
Safety always remains your responsibility and
you must continue paying careful attention to
your immediate surroundings when parking
and maneuvering.

The system cannot detect objects located
above the area that the sensors scan. These
objects, e.g. protruding load, overhang, or
truck tail lifts, will be ignored when computing
the parking procedure. The Parking Guidance
might therefore provide untimely steering
instructions. This could cause a collision.
Thus, do not use the Parking Guidance in such
situations.

G Warning!

Make sure no persons or animals are in the
area in which you are maneuvering. You could
otherwise injure them.

! Pay particular attention to low objects or
objects with flat surfaces, such as trailer
drawbars, posts, cross beams and curbs.
These types of objects cannot be detected
by Parking Guidance and may damage the
vehicle.
When PARKTRONIC is deactivated, Parking
Guidance is also unavailable.
Use Parking Guidance for parking spaces:
are parallel to the direction of travel
are on straight roads, not bends
Rthat are on the same level as the road, i.e.
not on the pavement, for example. Parking
Guidance may not detect flat curbs
Parking tips:

RNever

use Parking Guidance with snow
chains or an emergency spare wheel
installed.
RMake sure that the tire pressures are
always correct. This has a direct effect on
the steering instructions.
RThe way your vehicle is positioned in the
parking space after parking is dependent
on various factors. These include the
position and shape of the vehicles parked
in front and behind it and the conditions of
the location. In some cases, Parking
Guidance may guide you too far or not far
enough into a parking space. In some
cases, it may also lead you across or onto
the curb. If necessary, cancel the parking
procedure with Parking Guidance.

! If unavoidable, you should drive over
obstacles such as curbs slowly and not at
a sharp angle. Otherwise, you may damage
the wheels or tires.

ATTENTION ASSIST
Important safety notes
ATTENTION ASSIST helps you during long,
monotonous journeys, such as on highways
and arterial roads. It is active at speeds
between 50 mph (80 km/h) and 112 mph
(180 km/h).

If ATTENTION ASSIST detects fatigue or
increasing lapses in concentration on the part
of the driver, it suggests taking a break.

G Warning!

The ATTENTION ASSIST is only an aid to the
driver. It might not recognize fatigue or
increasing inattentiveness in time or fail to
recognize them at all. The system cannot
substitute a rested and attentive driver.
Fatigue can cause you to recognize dangers
too late, to misjudge potential dangers, or to
react slower. Therefore, make sure to be
rested before and during your trip. Take rests
early enough and regularly, especially during
long trips. Failure to do so could cause you to
recognize dangers too late which could result
in an accident and serious injury to you and/
or others.

ATTENTION ASSIST assesses your level of
fatigue or lapses in concentration by taking
the following criteria into account:
Ryour

personal driving style, e.g. steering
characteristics
Rjourney details, e.g. time of day and length
of journey
The functionality of ATTENTION ASSIST is

Night View Assist Plus
Important safety notes
In addition to the illumination provided by the
normal headlamps, Night View Assist Plus
uses infrared light to illuminate the road. A
camera at the top of the windshield picks up

the infrared light and displays a black-andwhite image in the COMAND display. The
image displayed in COMAND corresponds to
a road lit up by high-beam headlamps. This
enables you to see the road's course and any
obstacles in good time. If pedestrian
recognition is activated, pedestrians
recognized by the system are highlighted in
the Night View Assist Plus display.

G Warning

Night View Assist Plus is only an aid designed
to assist driving. It is not a substitute for
attentive driving. Do not rely solely on the
Night View Assist Plus display. Continue to
look through the windshield. You are
responsible for safety and must drive in
accordance with traffic conditions. You could
otherwise put yourself and others in danger.
The system may be impaired or unavailable if:
Rthere

is poor visibility, e.g. due to snow,
rain, fog or heavy spray.
Rthe windshield is dirty, fogged up or
covered, for instance by a sticker, in the
vicinity of the camera.
Ryou are driving on bends, uphill gradients
or downhill gradients.

Light from the headlamps of oncoming
vehicles does not affect the Night View Assist
Plus display in the multifunction display. This
is also the case if you cannot switch on the
high-beam headlamps because of oncoming
traffic.

G Warning!

The Night View Assist Plus cannot record
objects immediately in front of or next to the
vehicle. When maneuvering, continue to look
through the windshield. Make sure no
persons or animals are in the area in which
you are maneuvering. You could otherwise
injure them.

General information
The Lane Tracking package consists of Blind
Spot Assist (Y page 205) and Lane Keeping
Assist (Y page 207).

Blind Spot Assist
Important safety notes
Blind Spot Assist uses a radar sensor system
to monitor the areas on both sides of your
vehicle. It is active at speeds above
approximately 20 mph (30 km/h). A warning
display in the exterior mirrors draws your
attention to a vehicle detected in the
monitored area. If you switch on the
corresponding turn signal before changing
lane, you will also receive visual and audible
collision warnings. For this purpose, Blind
Spot Assist uses sensors in the rear bumper.

G Warning

Blind Spot Assist is only an aid designed to
assist driving. It may fail to detect some
vehicles and is no substitute for attentive
driving.
Blind Spot Assist cannot detect road and
traffic conditions. It may fail to detect narrow
vehicles, such as motorcycles or bicycles, or
may only detect them too late.
Monitoring may be affected by dirty sensors,
strong spray or poor visibility caused by snow,
rain or mist, for example. In this case, vehicles
are detected late or not at all.
Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognize dangers in time, cause an accident
and injure yourself and others.

Monitoring range of the sensors
Blind Spot Assist monitors the area up to 10 ft
(3 m) behind your vehicle and directly next to
your vehicle as shown in the diagram.

Always pay attention to traffic conditions and
your surroundings. Otherwise, you may fail to
recognize dangers in time, cause an accident
and injure yourself and others.

If the lanes are narrow, the system may be
unable to distinguish the neighboring lane
from the one beyond it. For this reason, the
system may indicate vehicles in the farther
lane, especially if the vehicles are driving in a
staggered formation in different lanes. In
particular, this may be the case if the vehicles
are driving at that edge of their lane which is
nearest your vehicle.

G Warning

Active Blind Spot Assist is only an aid
designed to assist driving. It is not a substitute
for attentive driving. In some cases, the
course-correcting brake application is not
sufficient to avoid a collision. In such a case,
you must steer, brake or accelerate.
In very rare cases, the system may
erroneously detect a danger of collision in the
area of crash barriers or similar lane borders
and apply the brakes. Active Blind Spot Assist
does not detect all traffic situations and road
users. Always make sure that there is
sufficient distance to the side for other traffic

Keeping Assist detects lane markings on the
road and warns you before you leave your
lane unintentionally. If you do not react to the
warning, a lane-correcting application of the
brakes can bring the vehicle back into the
original lane.

may detect the lane markings on the road
incorrectly or not at all.
The system may be impaired or may not
function if:
Rseveral or no lane markings for a single lane

are present.

insufficient illumination of the road, or due
to snow, rain, fog or spray.
Rthere is glare, e.g. from oncoming traffic,
the sun, or reflection from other vehicles.
Rthe windshield is dirty, fogged up or
covered, for instance by a sticker, in the
vicinity of the camera.
Rthe lane markings are worn away, dark or
covered up, e.g. by dirt or snow.
Rthere

Rthe

Rthe lane markings on the road are unclear,
e.g. near roadworks.
Rthe lane markings change quickly, e.g.
lanes branch off, cross one another or
merge.
Rthe road is narrow and winding.
Active Lane Keeping Assist cannot detect
road and traffic conditions. It is not a
substitute for attentive driving. You are
responsible for the vehicle's speed, braking in
good time, and steering correctly. Always
adapt your driving style to suit the prevailing
road and weather conditions. Always pay
attention to traffic conditions and your
surroundings. Otherwise, you may fail to
recognize dangers in time, cause an accident
and injure yourself and others.

Warning vibration in the steering wheel
A warning can be given when a front wheel
passes over a lane marking. It will warn you
by means of intermittent vibration in the
steering wheel for up to 1.5 seconds.
In order that you are warned only when
necessary and in good time if you cross the
lane marking, the system recognizes certain
conditions and warns you accordingly.
The warning vibration occurs earlier if:
Ryou

approach the outer lane marking on a
bend.
Rthe road has very wide lanes, e.g. a
freeway.
Rthe system recognizes solid lane markings.
The warning vibration occurs later if:
Rthe

road has narrow lanes.

ABS, BAS or ESP®.
Ryou switch on the turn signals. In this event,
the warnings are suppressed for a certain
period of time.
Lane-correcting brake application
If you leave your lane under certain
circumstances, the vehicle will brake briefly
on one side. This is designed to help you bring
the vehicle back into the original lane.
This function is available in the range between
40 mph and 120 mph (60 km/h and
200 km/h).
A lane-correcting brake application can only
be made after driving over a solid,
recognizable lane marking. You will be
warned beforehand by means of an
intermittent vibration in the steering wheel.
In addition, a lane with lane markings on both
sides must be recognized. The brake
application also slightly reduces driving
speed.
If a lane-correcting brake application occurs,
the following message appears in the
multifunction display:

i A further lane-correcting brake
application can only occur after your
vehicle has returned to the original lane.

G Warning

Active Lane Keeping Assist does not keep
your vehicle in its lane. It is only an aid
designed to assist driving. It is not a substitute
for attentive driving. In some cases, the lanecorrecting brake application is not sufficient
to bring your vehicle back to the original lane.
In such cases, you must steer the vehicle

yourself to ensure that it does not leave the
lane.
Active Lane Keeping Assist does not detect
road and traffic conditions. Always make sure
that there is sufficient distance to the side for
other traffic or obstacles. In rare cases,
unclear markings or particular structures on
the roadway can be recognized as solid lane
markings. An inappropriate brake application,
e.g. after intentionally driving over a solid lane
marking, may be interrupted at any time by
steering slightly in the opposite direction.
Active Lane Keeping Assist cannot take
account of weather conditions.
You are responsible for the vehicle's speed,

Vehicle equipment
i This manual describes all the standard
and optional equipment of your vehicle
which was available at the time of
purchase. Country-specific differences are
possible. Bear in mind that your vehicle
may not feature all functions described
here. This also refers to safety-related
systems and functions.

Important safety notes
You will find an illustration of the instrument
cluster in the "At a glance" section
(Y page 28).

G Warning

A driver's attention to the road and traffic
conditions must always be his/her primary
focus when driving.
For your safety and the safety of others,
selecting features through the multifunction
steering wheel should only be done by the
driver when traffic and road conditions permit
it to be done safely.
Bear in mind that at a speed of just 30 mph
(approximately 50 km/h ), your vehicle is
covering a distance of 44 feet (approximately
14 m) every second.

G Warning!

No messages will be displayed if either the
instrument cluster or the multifunction
display is inoperative.
As a result, you will not be able to see
information about your driving conditions,
such as
Rspeed
Routside temperature
Rwarning/indicator lamps
Rmalfunction/warning messages
Rfailure of any systems
Driving characteristics may be impaired.

If you must continue to drive, do so with added
caution. Contact an authorized MercedesBenz Center as soon as possible.

G Warning

Malfunction and warning messages are only
indicated for certain systems and are
intentionally not very detailed. The
malfunction and warning messages are
simply a reminder with respect to the
operation of certain systems. They do not
replace the owner's and/or driver's
responsibility to maintain the vehicle's
operating safety. Have all required
maintenance and safety checks performed on
the vehicle. Bring the vehicle to an authorized
Mercedes-Benz Center to address the
malfunction and warning messages.

Displays and operation
Coolant temperature gauge
G Warning

Driving when your engine is overheated can
cause some fluids which may have leaked into
the engine compartment to catch fire. You
could be seriously burned.
Steam from an overheated engine can cause
serious burns which can occur just by opening
the engine hood. Stay away from the engine
if you see or hear steam coming from it.
Stop the vehicle in a safe location away from
other traffic. Turn off the engine, get out of the
vehicle and do not stand near the vehicle until
the engine has cooled down.

The coolant temperature gauge is in the
instrument cluster on the right-hand side.
Under normal operating conditions and with
the specified coolant level, the coolant
temperature may rise to 248 ‡ (120 †).

! If the coolant temperature is too high a
display message is shown.

Displays and operation
If the coolant temperature rises above
248 ‡(120 †), do not drive any further as
this could damage the engine.

Tachometer
The red band in the tachometer indicates the
engine's overrevving range.

Operating the on-board computer
The on-board computer is activated as soon
as you turn the SmartKey to position 1 in the
ignition lock.
You can control the multifunction display and
the settings in the on-board computer using
the buttons on the multifunction steering
wheel.

! Do not drive in the overrevving range, as
this could damage the engine.
The fuel supply is interrupted to protect the
engine when the red band is reached.

Outside temperature display
The outside temperature display is in the
multifunction display.

G Warning!

The outside temperature indicator is not
designed to serve as an ice-warning device
and is therefore unsuitable for that purpose.
Indicated temperatures just above the
freezing point do not guarantee that the road
surface is free of ice. The road may still be icy,
especially in wooded areas or on bridges.

attention to road and traffic conditions.
X Engage the parking brake.
X Switch off the ignition.
X Have the occupant get out of the vehicle.
X Make sure that the seat is unoccupied and has no objects placed
on it, close the front-passenger door, and switch on the ignition.
Observe the 45(Y page 43) indicator lamps and the
multifunction display and check the following:
Seat unoccupied and ignition switched on:
Rthe 45 indicator lamp must light up and remain lit. When

the indicator lamp is on, OCS (Y page 43) has deactivated the
front-passenger air bag.

Manual or Front Passenger Airbag Disabled See
Operator's Manual display messages must not appear. Wait
for at least 60 seconds until the necessary system checks have
been completed and to make sure that the display messages do
not appear in the multifunction display.
If these conditions are met, the front-passenger seat can be
occupied again. Whether the 45 indicator lamp remains lit
or goes out depends on how OCS classifies the occupant.

A condition for activating cruise control has not been met.
You attempted to save a speed of less than 20 mph (30 km/h).
X If the situation allows, drive faster than 20 mph (30 km/h) and
save the speed.
X Check the activation conditions for cruise control
(Y page 177).

Tires
G Warning

Do not drive with a flat tire. A flat tire affects the ability to steer or brake the vehicle. You may
lose control of the vehicle. Continued driving with a flat tire will cause excessive heat build-up
and possibly a fire.

G Warning

Follow recommended tire inflation pressures.
Do not underinflate tires. Underinflated tires wear excessively and/or unevenly, adversely affect
handling and fuel economy, and are more likely to fail from being overheated.
Do not overinflate tires. Overinflated tires can adversely affect handling and ride comfort, wear
unevenly, increase stopping distance, and result in sudden deflation (blowout) because they are
more likely to become punctured or damaged by road debris, potholes etc.

Each tire, including the spare tire (if there is one), should be inspected at least every two weeks
when they are cold and pumped to the pressure recommended by the vehicle manufacturer (see
the tire and load data label on the B-pillar on the driver's side or the tire pressure table on the
inside of the fuel filler flap of your vehicle, if there is one). If your vehicle has tires which are a
different size to those on the tire and load data label or those specified in the tire pressure table,
if there is one, you should determine the correct tire pressure for these tires.
As an added safety feature, your vehicle has been equipped with a tire pressure monitor (TPMS).
An indicator lamp lights up if one or more of your tires are significantly underinflated. Accordingly,
when the low tire pressure indicator lamp lights up, you should stop and check your tires as soon
as possible, and inflate them to the proper pressure. Driving on a significantly underinflated tire
causes the tire to overheat and can lead to tire failure.
An excessively low tire pressure also increases fuel consumption, reduces the service life of the
tires and may impair the driving and braking characteristics of the vehicle. Please note that the
TPMS is not a substitute for proper tire maintenance and it is the driver's responsibility to maintain
correct tire pressure, even if underinflation has not reached the level at which the low tire
pressure indicator lamp of the TPMS lights up.

Warning and indicator lamps in the instrument cluster
Your vehicle has also been equipped with a TPMS malfunction indicator to indicate when the
system is not operating properly. The TPMS malfunction indicator is combined with the low tire
pressure indicator lamp. When the system detects a malfunction, the indicator lamp will flash
for approximately one minute and then remain illuminated. This sequence will continue upon
subsequent vehicle start-ups as long as the malfunction exists. When the malfunction indicator
is lit, the system may not be able to detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of reasons, including the installation of incompatible
replacement or alternate tires or wheels on the vehicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunction indicator after replacing one or more tires or wheels
on your vehicle to ensure that the replacement or alternate tires and wheels allow the TPMS to
continue to function properly.

possible. Bear in mind that your vehicle
may not feature all functions described
here. This also refers to safety-related
systems and functions.

Loading guidelines
G Warning!

Always fasten items being carried as securely
as possible. Use cargo tie-down rings and
fastening materials appropriate for the weight
and size of the load.
In an accident, during hard braking or sudden
maneuvers, loose items will be thrown around
inside the vehicle. This can cause injury to
vehicle occupants unless the items are
securely fastened in the vehicle.
To help avoid personal injury during a collision
or sudden maneuver, exercise care when
transporting cargo. Do not pile luggage or
cargo higher than the seat backrests.
The trunk is the preferred place to carry
objects.
Never drive a vehicle with the trunk open.
Deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in
unconsciousness and death.

The handling characteristics of a laden
vehicle are dependent on the distribution of
the load within the vehicle. For this reason,
you should observe the following notes when
transporting a load:
RWhen transporting a load, never exceed the
maximum permissible gross vehicle weight
or the permissible axle loads for the vehicle
(including occupants). The values are

stated on the vehicle identification plate on
the B-pillar on the driver's side.
RPosition heavy loads as far forwards as
possible and as low down in the trunk/
cargo compartment as possible.
RThe load must not protrude above the
upper edge of the seat backrests.
Ralways place the load against the rear or
front seat backrests. Make sure that the
seat backrests are securely locked into
place.
RAlways place the load behind unoccupied
seats if possible.
RSecure the load with sufficiently strong and
wear-resistant tie down. Pad sharp edges
for protection.

The 115V AC socket operates at high voltage.
Use the 115V AC socket in the vehicle with
the same caution and prudence that you
exercise when using power outlets at home.
Keep any fluids away from the 115V AC
socket. Do not clean the socket with fluids or
tapered objects. Keep the 115V AC socket
cover in the closed position, when not in use.
Otherwise, you could suffer an electric shock
and be seriously or even fatally injured.

G Warning!

A device that you connect must have a
suitable plug that complies with U.S.
standards. Never pull on the cable to unplug
a plug from the 115V AC socket. Do not use
a damaged connection cable. The 115V AC
socket may not be connected to another
115V AC power source. Do not use converters
to a grounding plug with the 115V AC socket.
This could cause serious personal injury to
you and/or others.

G Warning!

If the 115V AC socket is damaged or torn out
of the trim, do not use or touch the 115V AC
socket. Using a 115V AC socket that is
damaged or torn out of the trim could cause
serious personal injury to you and/or others.

The 115 V AC socket : provides an
alternating voltage of 115 V, so that small
electronic devices can be connected. These

G Warning

Before programming the integrated remote
control to a garage door opener or gate
operator, make sure people and objects are
out of the way of the device to prevent
potential harm or damage. When
programming a garage door opener, the door
moves up or down. When programming a gate
operator, the gate opens or closes.
Do not use the integrated remote control with
any garage door opener that lacks safety stop
and reverse features as required by U.S.
federal safety standards (this includes any
garage door opener model manufactured
before April 1, 1982). A garage door that
cannot detect an object - signaling the door
to stop and reverse - does not meet current
U.S. federal safety standards.
When programming a garage door opener,
park vehicle outside the garage.

Notes on programming the remote
control
Canadian radio frequency laws require
transmitter signals to "time-out" (or quit) after
several seconds of transmission. This may
not be long enough for the integrated signal
transmitter to pick up the signal during
programming. Similar to this Canadian law,

some U.S. gate operators are designed to
"time-out" in the same manner.
If you live in Canada or have difficulties
programming the garage door opener
(regardless of where you live) when using the
programming steps (see above), proceed as
follows:
X Press transmitter button (;, = or ?) and
hold it down during the following steps until
the setup has been completed
successfully.
X At the same time, press transmitter button
B of the garage door remote control for
two seconds, then release it for two
seconds, then press it again for two
seconds.
X Repeat this sequence on transmitter
button B of the garage door remote
control until the frequency signal has been
learned.
X If the setup procedure is successful,
indicator lamp : flashes once slowly and
goes out after a few seconds.
X Continue with the other programming
steps (see above).
Problems when programming
If you have problems when programming the
integrated remote control, please note the
following:
Rcheck

the transmitter frequency of garage
door remote control A (which can usually
be found on the rear of the remote control).
The integrated remote control is
compatible with equipment that operates
in the frequency range 280 to 390 MHz.
Rreplace the batteries in garage door remote
control A. This increases the likelihood of
garage door remote control A sending a
strong and precise signal to the integrated

! Do not park the vehicle for an extended
period right after cleaning it, particularly
after having cleaned the wheels with wheel
cleaner. Wheel cleaners could cause
increased corrosion of the brake discs and
brake pads/linings. For this reason, you
should drive for a few minutes after
cleaning. Braking heats the brake discs and
brake pads, thus drying them. The vehicle
can then be parked up.

Exterior care
Automatic car wash
G Warning!

Braking efficiency is reduced after washing
the vehicle. This could cause an accident. For
this reason, you must drive particularly

carefully after washing the vehicle until the
brakes have dried.

G Risk of accident

The vehicle is braked when the HOLD function
or DISTRONIC PLUS is activated. Therefore,
deactivate the HOLD function and DISTRONIC
PLUS before the vehicle is washed in an
automatic car wash.

You can wash the vehicle in an automatic car
wash from the very start.

! Never clean your vehicle in a Touchless
Automatic Car Wash as these use special
cleaning agents. These cleaning agents can
damage the paintwork or plastic parts.
If the vehicle is very dirty, pre-wash it before
cleaning it in an automatic car wash.

! In car washes with a towing mechanism,

it thoroughly with a chamois.
X Do not allow the cleaning agent to dry on
the paintwork.

Power washers
G Warning!

Do not use power washers with circular-jet
nozzles (dirt grinders) to clean your vehicle, in
particular the tires. You could otherwise
damage the tires and cause an accident.

! Keep the distance between the vehicle
and the nozzle of the power washer at
11.8 in (30 cm). Information about the
correct distance is available from the
equipment manufacturer.
Move the power washer nozzle around
when cleaning your vehicle.
Do not aim directly at any of the following:

Cleaning the paintwork

Matte finish care

Scratches, corrosive deposits, areas affected
by corrosion and damage caused by
inadequate care cannot always be completely
repaired. In such cases, visit a qualified
specialist workshop immediately, e.g. an
authorized Mercedes-Benz Center.
X Remove impurities immediately, where
possible, whilst avoiding rubbing too hard.
X Soak insect remains with insect remover
and rinse off the treated areas afterwards.
X Soak bird droppings with water and rinse
off the treated areas afterwards.
X Remove coolant, brake fluid, tree resin,
oils, fuels and greases by rubbing gently
with a cloth soaked in petroleum ether or
lighter fluid.
X Use tar remover to remove tar stains.
X Use silicone remover to remove wax.

If your vehicle has a clear matte finish,
observe the following instructions in order to
avoid damage to the paintwork due to
incorrect care.

! Do not affix:
Rstickers

! Never polish the vehicle. Polishing causes
the finish to shine.

! Do not use paintwork cleaner, grinding or
polishing products or gloss preservers such
as wax. These products are only suitable for
high-gloss surfaces. Using them on
vehicles with matte paintwork can cause
severe damage to the surface (shiny,
mottled patches).
Always have paintwork repairs performed
at a qualified specialist workshop, e.g. an
authorized Mercedes-Benz Center.

! Do not use wash programs with a hot wax
treatment under any circumstances.

i Use only insect remover and car shampoo
from the range of recommended and
approved Mercedes-Benz care products.

Rmagnetic

plates or similar items
to painted surfaces. You could otherwise
damage the paintwork.
If water no longer forms "beads" on the
painted surface, paint care products should
be used that have been approved and
recommended by Mercedes-Benz. This is the
case approximately every three to five
months, depending on climatic conditions
and the care product used.
If dirt has entered the paint surface or the
paintwork has become dull, a paint cleaner
should be used that has been approved and
recommended by Mercedes-Benz.
Never use such care products in direct
sunlight or on a hot hood.

Cleaning the plastic trim
G Warning!

When cleaning the steering wheel boss and
dashboard, do not use cockpit sprays or
cleaning agents containing solvents. Cleaning
agents containing solvents cause the surface
to become porous, and as a result, plastic
parts may break away and be thrown around
the interior when an air bag is deployed, which
may result in severe injuries.

! Do not affix the following to plastic
surfaces:
Rstickers
Rfilms
Rscented

oil bottles or similar items
You can otherwise damage the plastic.

! Do not allow cosmetics, insect repellent
or sunscreen to come into contact with the
plastic trim. This maintains the high-quality
look of the surfaces.
X

Wipe the plastic trim with a damp, lint-free
cloth, e.g. a microfiber cloth.
X Heavy soiling: use car care and cleaning
products recommended and approved by
Mercedes-Benz.
The surface may change color temporarily.
Wait until the surface is dry again.

Wipe the wooden trim and trim strips with
a damp, lint-free cloth, e.g. a microfiber
cloth.
X Heavy soiling: use car care and cleaning
products recommended and approved by
Mercedes-Benz.

! Do not use solvent-based cleaning agents
such as tar remover, wheel cleaners,
polishes or waxes. There is otherwise a risk
of damaging the surface.

! Do not use chrome polish for trim strips.
The trim strips have a chrome look but are
mostly made of anodized aluminum and
can lose their shine if chrome polish is
used. Use a damp, lint-free cloth instead
when cleaning the trim strips.
Chrome polish can be used to remove very
heavy soiling from trim strips which you are
sure are made of chrome. If you are unsure
as to whether a trim strip is chrome-plated
or not, consult an authorized MercedesBenz Center.

Cleaning the seat covers
! Do not use microfiber cloths to clean
genuine leather, artificial leather or
Alcantara® covers. If used often, these can
damage the cover.

Jump-starting
G Warning

! Avoid repeated and lengthy starting attempts. Otherwise, non-combusted fuel may
damage the catalytic converter36 and create a risk of fire.
Do not use a rapid-charging device to start the engine.
Make sure the jumper cables are not damaged.
Make sure the jumper cables are not touching any other metal objects when they are
connected to the battery.
If your vehicle's battery is discharged, the engine can be jump-started from another vehicle
or from a second battery using jumper cables.
Observe the following points:
X The battery is not accessible in all vehicles. If the other vehicle's battery is not accessible,
jump-start the vehicle using a second battery or a jump-starting device.
X Only jump-start the vehicle when the engine is cold and the catalytic converter system has
cooled down37 .
X Do not start the engine if the battery is frozen. Let the battery thaw first.
X Jump-starting may only be performed from batteries with a nominal voltage of 12 V.
If you jump-start using a battery with higher voltage, it may damage the electrical systems
of the vehicle.
X Only use jumper cables which have a sufficient cross-section and insulated terminal clamps.
X Make sure that the jumper cables cannot come into contact with parts, such as the pulley
or the fan. These parts move when the engine is started and while it is running.
X If the battery is fully discharged, leave the battery that is being used to jump-start connected
for a few minutes before attempting to start. This charges the battery a little.

Important safety notes
The fuses in your vehicle serve to close down
faulty circuits. If a fuse blows, all the
components on the circuit and their functions
will fail.

G Warning

Only use fuses approved by Mercedes-Benz
with the specified amperage for the system in
question and do not attempt to repair or
bridge a blown fuse. Using other than
approved fuses or using repaired or bridged
fuses may cause an overload leading to a fire,
and/or cause damage to electrical
components and/or systems. Have the cause
determined and remedied by an authorized
Mercedes-Benz Center.

Blown fuses must be replaced with fuses of
the same rating, which you can recognize by
the color and value. The fuse ratings are listed
in the fuse allocation chart. An authorized
Mercedes-Benz Center will be happy to
advise you.

i If a fuse has blown, visit a breakdown
service or an authorized Mercedes-Benz
Center.
If the newly inserted fuse also blows, have the
cause traced and rectified at a qualified
specialist workshop, e.g. an authorized

Important safety notes
Vehicle equipment
i This manual describes all the standard
and optional equipment of your vehicle
which was available at the time of
purchase. Country-specific differences are
possible. Bear in mind that your vehicle
may not feature all functions described
here. This also refers to safety-related
systems and functions.

Important safety notes

Tires and wheels

2010-05-20T13:33:46+02:00 - Seite 350
Version: 3.0.3.6

Contact an authorized Mercedes-Benz Center
if you require information on tested and
recommended tires and wheels for summer
and winter driving. Advice on purchasing and
caring for tires is also available there.

G Warning

Replace rims or tires with the same
designation, manufacturer and type as shown
on the original part. For further information
contact an authorized Mercedes-Benz Center.
If incorrectly sized rims and tires are
mounted, the wheel brakes or suspension
components can be damaged. Also, the
operating clearance of the wheels and the
tires may no longer be correct.

G Warning

Worn, old tires can cause accidents. If the tire
tread is worn to minimum tread depth, or if
the tires have sustained damage, replace
them.
When replacing rims, only use genuine
Mercedes-Benz wheel bolts specified for the
particular rim type. Failure to do so can result
in the bolts loosening and possibly an
accident.
Retreaded tires are not tested or
recommended by Mercedes-Benz, since
previous damage cannot always be
recognized on retreads. The operating safety
of the vehicle cannot be assured when such
tires are used.

G Warning

If you feel a sudden significant vibration or
ride disturbance, or you suspect that possible
damage to your vehicle has occurred, you
should turn on the hazard warning flashers,
carefully slow down, and drive with caution to
an area which is a safe distance from the road.
Inspect the tires and the vehicle underbody
for possible damage. If the vehicle appears
unsafe, have the vehicle towed to the nearest
authorized Mercedes-Benz Center or tire
dealer for repairs.

G Warning

Do not drive with a flat tire. A flat tire affects
the ability to steer or brake the vehicle. You
might lose control of the vehicle. Continued
driving with a flat tire or driving at high speed
with a flat tire will cause excessive heat buildup and possibly a fire.

! For safety reasons, Mercedes-Benz
recommends that you only use tires,
wheels and accessories which have been
approved by Mercedes-Benz specifically
for your vehicle. These tires have been
specially adapted for use with the control
systems, such as ABS or ESP®, and are
marked as follows:
RMO = Mercedes-Benz Original
RMOE = Mercedes-Benz Original Extended
(tires with run-flat characteristics)
RMO1 = Mercedes-Benz Original (AMG)
Only use Mercedes-Benz Original Extended
tires on wheels that have been specifically
approved by Mercedes-Benz.
If you use other tires, wheels and
accessories, Mercedes-Benz cannot
accept any responsibility for damage that
may result from this. Further information
about tires, wheels and approved
combinations can be obtained from any
authorized Mercedes-Benz Center.

Maintenance and care of wheels and tires
Directives to be observed
ROnly

mount tires and wheels of the same
type and make.
ROnly mount tires of the correct size onto
the wheels.
RAfter mounting new tires, run them in at
moderate speeds for the first 60 miles
(100 km) as they only reach their full
performance after this distance.
RDo not use tires until they are excessively
worn as the tire traction on wet road
surfaces decreases significantly when the
tread depth is less than 1/8 in (3 mm).
RIf the vehicle is heavily laden, check the tire

pressure and adjust it if necessary.
parking your vehicle, make sure that
the tires do not get deformed by the curb
or other obstacles. If it is necessary to drive
over curbs, speed humps or similar
elevations, try to do so slowly and at an
obtuse angle. Otherwise, the tires,
particularly the sidewalls, can get
damaged.

RWhen

Damaged wheels can cause a loss of tire
pressure.
RRegularly check the tire tread depth and
the condition of the tread across the whole
width of the tire (Y page 351). If necessary,
turn the front wheels to full lock in order to
inspect the inner side of the tire surface.
RAll wheels must have a valve cap to protect
the valve against dirt and moisture. Do not
install anything on the valve (such as tire
pressure monitoring systems) other than
the standard valve cap or other valve caps
approved by Mercedes-Benz for your
vehicle.
RRegularly check the pressure of all the tires
including the emergency spare wheel or the
spare wheel, particularly prior to long trips,
and correct the pressure as necessary
(Y page 352).

Service life of tires
The service life of tires depends on the
following factors amongst other things:
Rdriving

Maintenance and care of wheels and
tires
Checking wheels and tires
G Warning

Regularly check the tires for damage.
Damaged tires can cause tire inflation
pressure loss. As a result, you could lose
control of your vehicle.
Worn, old tires can cause accidents. If the tire
tread is worn to minimum tread depth, or if
the tires have sustained damage, replace
them.
RRegularly

check the wheels and tires of
your vehicle for damage (e.g. cuts,
punctures, tears, bulges on tires and
deformation or cracks or severe corrosion
on wheels), at least once a month, as well
as after driving off-road or on rough roads.

Tire tread
G Warning

Although the applicable federal motor vehicle
safety laws consider a tire to be worn when
the tread wear indicators (TWI) become
visible at approximately 1/16 in (1.6 mm), we
recommend that you do not allow your tires
to wear down to that level. As tread depth
approaches 1/8 in (3 mm), the adhesion
properties on a wet road are sharply reduced.

Tire pressures
Depending upon the weather and/or road
surface (conditions), the tire traction varies
widely.

Do not use tires until they are excessively
worn as the tire traction on wet road surfaces
decreases significantly when the tread depth
is less than 1/8 in (3 mm).

Tires and wheels

Tread wear indicators (TWI) are required by
law. Six indicators are positioned over the tire
tread. They are visible as soon as a tread
depth of approximately 1/16 in (1.6 mm) is
reached. If this is the case, the tire is so worn
that it must be replaced.
The recommended tread depth for summer
tires is at least 1/8 in (3 mm). The
recommended tread depth for winter tires is
at least 1/6 in (4 mm).

Bar marking : for tread wear is integrated
into the tire tread.

Storing tires
Store tires that are not being used in a cool,
dry and preferably dark place. Protect the
tires from contact with oil, grease and fuel.

Cleaning tires
G Warning

Do not use power washers with circular jet
nozzles (concentrated-power jets) to clean
your vehicle, especially for cleaning tires. You

could otherwise damage the tires and cause
an accident.

Tire pressures
Recommended tire pressures
G Warning

Follow recommended tire inflation pressures.
Do not underinflate tires. Underinflated tires
wear excessively and/or unevenly, adversely
affect handling and fuel economy, and are
more likely to fail from being overheated.
Do not overinflate tires. Overinflated tires can
adversely affect handling and ride comfort,
wear unevenly, increase stopping distance,
and result in sudden deflation (blowout)
because they are more likely to become
punctured or damaged by road debris,
potholes etc.
Do not overload the tires by exceeding the
specified load limit as indicated on the Tire
and Loading Information placard on the
driver's door B-pillar. Overloading the tires
can overheat them, possibly causing a
blowout. Overloading the tires can also result
in handling or steering problems, or brake
failure.

You will find a table of recommended tire
pressures on the Tire and Loading
Information placard on the B-pillar on the
driver's side (Y page 360). You will find a
table of tire pressures for various operating
conditions on the inside of your vehicle's fuel
filler flap.
Use a suitable pressure gauge. The outer
appearance of a tire does not permit any
reliable conclusion about the tire pressure.
On vehicles equipped with the electronic tire
pressure monitor, the tire pressure can be
checked using the on-board computer.

G Warning

Should the tire pressure drop repeatedly:

vehicle-specific and may deviate from the
data shown here. The tire pressure
specifications for your vehicle can be found

You will find recommended tire pressure
specifications : for cold tires and for a fully
loaded vehicle on the Tire and Loading
Information placard. The tire pressure
specifications apply to tires which are
installed at the factory.

Important notes on tire pressures
G Warning

If the tire pressure drops repeatedly, check
the tires for punctures from foreign objects
and/or whether air is leaking from the valves
or from around the rim.

The temperature and pressure of the tires
increase when the vehicle is in motion. This
is dependent on the driving speed and the
load.
If you wish to drive at high speeds of
100 mph (160 km/h) or higher when this is
allowed, use the tire pressure table on the
inside of the fuel filler flap to set the correct
tire pressures when the wheels are cold. If the
tire pressure is not set correctly, this can lead
to an excessive build up of heat and a sudden
loss of pressure.
For more information, contact a qualified
specialist workshop, e.g. an authorized
Mercedes-Benz Center.

i Ride comfort may be affected if the tire
pressure is adjusted to the recommended
value for speeds of over
100 mph(160 km/h).
Z

Tires and wheels

Only correct tire pressures when the tires are
cold. The tires are cold when the vehicle has
been parked for at least three hours or driven
for less than 1 mile (1.6 km). The tire
temperature changes depending on the
outside temperature, the vehicle speed and
the tire load. If the tire temperature changes
by 18 ‡ (10 †), the tire pressure changes by
approximately 10 kPa (0.1 bar/1.5 psi). Take
this into account when checking the pressure
of warm tires and only correct the tire
pressure if it is too low for the current
operating conditions. If you check the tire
pressure when the tires are warm, the reading
will be higher than if the tires were cold. This
is normal. Do not reduce the tire pressure to
the value specified for cold tires. The tire
pressure would otherwise be too low.
Observe the recommended tire pressure
specifications for cold tires on the Tire and
Loading Information placard on the B-pillar on
the driver's side.

Check the tire pressure at least once a month.
Only check and correct tire pressures when
the tires are cold (Y page 352).

Checking the tire pressures manually
In order to determine and adjust the tire
pressures, proceed as follows:
X

Remove the valve cap of the tire you wish
to check.
X Press the tire pressure gauge securely onto
the valve.
X Read the tire pressure and compare it with
the recommended value on the Tire and
Loading Information placard on the
B-pillar on the driver's side of your vehicle.
X If necessary, increase the tire pressure to
the recommended value (Y page 352).
X If the tire pressure is too high, release air
by pressing down the metal pin in the valve
using the tip of a pen, for example. Then,
check the tire pressure again using the tire
pressure gauge.
X Screw the valve cap onto the valve.
X Repeat the steps for the other tires.

Tire pressure loss warning system
(Canada only)
Important safety notes
While the vehicle is in motion, the tire
pressure loss warning system monitors the
set tire pressure using the rotational speed of
the wheels. This enables the system to detect
significant pressure loss in a tire. If the speed
of rotation of a wheel changes as a result of
a loss of pressure, a corresponding warning
message will appear in the multifunction
display.

G Warning

If the Check Tire Pressure Soon message
appears in the multifunction display, one or
more tires are significantly underinflated.
Stop the vehicle as soon as possible and
inflate the tires to the pressure specified on
the vehicle's Tire and Loading Information
placard or (where available) in the tire
pressure table.
Driving on a significantly underinflated tire
causes the tire to overheat and can lead to
tire failure. Underinflation also reduces fuel
efficiency and tire tread life, and may affect
the vehicle's handling and stopping ability.
Check all tires when cold, including the spare
tire, at least once a month. The tires should
be inflated to the recommended pressure.

G Warning!

The tire pressure loss warning system does
not provide a warning for wrongly selected tire
inflation pressures. Always adjust tire
inflation pressure according to the Tire and
Loading Information placard on the driver's
door B-pillar or on the tire inflation pressure
label located on the inside of the fuel filler flap.
The tire pressure loss warning system does
not replace regular checks of the tire inflation
pressures since a gradual pressure loss in
more than one tire cannot be detected by the
tire pressure loss warning system.
The tire pressure loss warning system is not
able to issue a warning due to a sudden
dramatic loss of tire inflation pressure (e.g.
tire blowout caused by a foreign object). In
this case bring the vehicle to a halt by carefully
applying the brakes and avoiding abrupt
steering maneuvers.

Tire pressure monitoring system
Important safety notes
If a tire pressure monitor is installed, the
vehicle's wheels have sensors installed that
monitor the tire pressures in all four tires. The
tire pressure monitor warns you when the
pressure drops in one or more of the tires. The
tire pressure monitor only functions if the
correct wheel electronics units are installed
in all wheels.

The tire pressure monitor has a yellow
warning lamp in the instrument cluster for
indicating pressure loss/malfunctions (USA)
or pressure loss (Canada). Depending on how
the warning lamp flashes or lights up, a tire
pressure that is too low or a malfunction in
the tire pressure monitor is displayed:
Rif

the warning lamp is lit continuously, the
tire pressure on one or more tires is
significantly too low. The tire pressure
monitor is not malfunctioning.
RUSA only: if the warning lamp flashes for
60 seconds and then remains lit constantly,
the tire pressure monitor is malfunctioning.

G Warning

Each tire, including the spare (if provided),
should be checked at least once a month
when cold and inflated to the inflation
pressure recommended by the vehicle
manufacturer on the Tire and Loading
Information placard on the driver’s door Bpillar or the tire inflation pressure label on the
inside of the fuel filler flap. If your vehicle has
tires of a different size than the size indicated
on the Tire and Loading Information placard
or the tire inflation pressure label, you should
determine the proper tire inflation pressure
for those tires.
As an added safety feature, your vehicle has
been equipped with a tire pressure monitoring
system (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires are significantly underinflated.
Accordingly, when the low tire pressure
telltale illuminates, you should stop and check
your tires as soon as possible, and inflate
them to the proper pressure. Driving on a
significantly underinflated tire causes the tire
to overheat and can lead to tire failure.
Underinflation also reduces fuel efficiency
and tire tread life, and may affect the vehicle's
handling and stopping ability. Please note that
the TPMS is not a substitute for proper tire
maintenance, and it is the driver's
responsibility to maintain correct tire
pressure, even if underinflation has not

reached the level to trigger illumination of the
TPMS low tire pressure telltale.
USA only:
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the tire pressure monitoring system is not
operating properly. The TPMS malfunction
indicator is combined with the low tire
pressure telltale. When the system detects a
malfunction, the telltale will flash for
approximately one minute and then remain
continuously illuminated. This sequence will
continue upon subsequent vehicle start-ups
as long as the malfunction exists. When the
malfunction indicator is lit, the system may
not be able to detect or signal low tire
pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of
incompatible replacement or alternate tires
or wheels on the vehicle that prevent the
TPMS from functioning properly. Always
check the TPMS malfunction telltale after
replacing one or more tires or wheels on your
vehicle to ensure that the replacement or
alternate tires and wheels allow the TPMS to
continue to function properly.

G Warning

It is the driver's responsibility to set the tire
inflation pressure to the recommended cold
tire inflation pressure. Underinflated tires
affect the ability to steer or brake the vehicle.
You might lose control over the vehicle.

When you restart the tire pressure monitor,
all existing warning messages are deleted and
the warning lamps go out. The monitor uses
the currently set tire pressures as the
reference values for monitoring.
The TPMS must be restarted when you set the
tire pressure to a new value (as a result of
changed handling or load characteristics, for
example). The TPMS then monitors the new
tire pressure values.

i Canada only: in most cases, the tire
pressure monitor recognizes the new
reference values automatically. However,
you can also define reference values
manually as described here.
Restart the tire pressure monitor after you
have set the tire pressure to the value
recommended for the desired driving

The following steps have been developed as required of all manufacturers under Title 49, Code
of U.S. Federal Regulations, Part 575 pursuant to the "National Traffic and Motor Vehicle
Safety Act of 1966".
X Step 1: Locate the statement "The combined weight of occupants and cargo should never
exceed XXX kg or XXX lbs." on your vehicle's Tire and Loading Information placard.
X Step 2: Determine the combined weight of the driver and passengers that will be traveling
in your vehicle.
X Step 3: Subtract the combined weight of the driver and passengers from XXX kilograms or
XXX lbs.
X Step 4: The resulting figure equals the available amount of cargo and luggage load capacity.
For example, if the "XXX" amount equals 1400 lbs and there will be five 150 lbs passengers
in your vehicle, the amount of available cargo and luggage load capacity is 650 lbs (1400 750 (5 x 150) = 650 lbs).
X Step 5: Determine the combined weight of luggage and cargo being loaded on the vehicle.
For reasons of safety, that weight must not exceed the available cargo and luggage cargo
capacity calculated in step 4.
X Step 6 (if applicable): If you intend to tow a trailer behind your vehicle, the load on the
trailer is transferred to your vehicle. Consult this Operator's Manual to determine how this
reduces the available cargo and luggage load capacity of your vehicle (Y page 365).
The following table shows examples of how to calculate total and cargo load capacities with
varying seating configurations and number and size of occupants. The following examples use
a cargo limit of 1500 lbs (680 kg). This is for illustration purposes only. Make sure you
always use the actual load limit for your vehicle stated on the vehicle's Tire and Loading
Information placard (Y page 361).

Version: 3.0.3.6

The tread wear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified
U.S. government test track. For example, a
tire graded 150 would wear one and one-half
times as well on the government test track as
a tire graded 100.
The relative performance of tires depends
upon the actual conditions of their use,
however, and may depart significantly from
the norm due to variations in driving habits,
service practices and differences in road
characteristics and climate conditions.

Traction
G Warning

The traction grade assigned to this tire is
based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.

The traction grades, from highest to lowest,
are AA, A, B, and C. These grades represent
the tire's ability to stop on a wet surface as
measured under controlled conditions on
specified government test surfaces of asphalt
and concrete. A tire marked C may have poor
traction performance.

G Warning

If ice has formed on the road, tire traction will
be substantially reduced. Under such weather
conditions, drive, steer and brake with
extreme caution.

The safe speed on a wet, snow covered or icy
road is always lower than on dry road
surfaces.
You should pay special attention to road
conditions when temperatures are around
the freezing point.
Mercedes-Benz recommends a minimum tire
tread depth of 1/6 in (4 mm) for all four winter
tires (Y page 175) to maintain normal driving
characteristics in winter. Winter tires can
reduce the braking distance on snow covered
surfaces in comparison to summer tires. The
braking distance is still much further than on
surfaces that are not icy or covered with
snow. Take appropriate care when driving.

! Avoid wheelspin. This can lead to damage
to the drive train.

Temperature
G Warning

The temperature grade for this tire is
established for a tire that is properly inflated
and not overloaded. Excessive speed,
underinflation, or excessive loading, either
separately or in combination, can cause
excessive heat build-up and possible tire
failure.

The temperature grades are A (the highest),
B, and C. These represent the tire's
resistance to the generation of heat and its
ability to dissipate heat when tested under
controlled conditions on a specified indoor
laboratory test wheel. Sustained high
temperature can cause the material of the tire
to degenerate and reduce tire life.
Furthermore, excessive temperature can lead
to sudden tire failure. Grade C corresponds
to a level of performance that all passenger

Overview of tire labeling
The following markings are on the tire in
addition to the tire name (sales designation)
and the manufacturer's name:

Interchanging the wheels
G Warning

Rotate front and rear wheels only if the tires
are of the same dimension.
If your vehicle is equipped with mixed-size
tires (different tire dimensions front vs. rear),
tire rotation is not possible.

Have the tightening torque checked after
changing a wheel. Wheels could become
loose if not tightened with a torque of
96 lb-ft (130 Nm).
Only use genuine Mercedes-Benz wheel bolts
specified for your vehicle's rims.

The wear patterns on the front and rear tires
differ, depending on the operating conditions.
Rotate the wheels before a clear wear pattern
has formed on the tires. Front tires typically
wear more on the shoulders and the rear tires
in the center.
If your vehicle's tire configuration allows, you
can rotate the wheels according to the
intervals in the tire manufacturer's warranty
book in your vehicle documents. If no
warranty book is available, the tires should be
rotated every 3000 to 6000 miles
(5000 to 10000 km), or earlier if tire wear
requires. Do not change the direction of
wheel rotation.
Clean the contact surfaces of the wheel and
the brake disc thoroughly every time a wheel
is rotated. Check the tire pressures.

General: depending on the manufacturer's
standards, the size imprinted in the tire wall
may not contain any letters or may contain
one letter that precedes the size description.
If there is no letter preceding the size
description (as shown above): these are
passenger vehicle tires according to
European manufacturing standards.
If "P" precedes the size description: these are
passenger vehicle tires according to U.S.
manufacturing standards.
If "LT" precedes the size description: these
are light truck tires according to U.S.
manufacturing standards.
If "T" precedes the size description: these are
compact emergency spare wheels at high tire
pressure, to be used only temporarily in an
emergency.
Tire width: tire width : shows the nominal
tire width in millimeters.
Nominal aspect ration: aspect ratio ; is
the size ratio between the tire height and the
tire width and is shown in percent. The aspect

ratio is calculated by dividing the tire width by
the tire height.
Tire code: tire code = specifies the tire type.
"R" represents radial tires. "D" represents
diagonal tires, "B" represents diagonal radial
tires.
Optionally, tires with a maximum speed of
over 149 mph (240 km/h) may have "ZR" in
the size description depending on the
manufacturer (e.g. 245/40 ZR 18).
Rim diameter: rim diameter ? is the
diameter of the bead seat, not the diameter
of the rim flange. The rim diameter is
specified in inches (in).
Load bearing index: load bearing index A
is a numerical code which specifies the
maximum load-bearing capacity of a tire.

G Warning

The tire load rating must always be at least
half of the GAWR of your vehicle. Otherwise,
sudden tire failure may be the result which
could cause an accident and/or serious injury
to you or others.
Always replace rims and tires with rims and
tires having the same specifications
(designation, manufacturer and type) as
shown on the original part.

G Warning

Do not overload the tires by exceeding the
specified load limit as indicated on the Tire
and Loading Information placard on the
driver's door B-pillar. Overloading the tires
can overheat them, possibly causing a
blowout. Overloading the tires can also result
in handling or steering problems, or brake
failure.

Example:
The load bearing index 91 is equivalent to a
maximum load of 1356 lbs (615 kg) that the
tire can carry. For further information on the
maximum tire load in kilograms and pounds,
see (Y page 365).

Tire labeling
For further information on the load bearing
index, see load index (Y page 370).
Speed index: speed index B specifies the
approved maximum speed of the tire.

G Warning

Even when permitted by law, never operate a
vehicle at speeds greater than the maximum
speed rating of the tires.
Exceeding the maximum speed for which tires
are rated can lead to sudden tire failure,
causing loss of vehicle control and possibly
resulting in an accident and/or serious
personal injury and possible death, for you
and for others.

Regardless of the speed index always observe
the speed limits. Drive carefully and adapt
your driving style to the traffic conditions.
Summer tires

The service specifications consists of load
bearing index A and speed index B.
RIf the size description of your tire includes
"ZR" and there are no service
specifications, ask the tire manufacturer in
order to find out the maximum speed.
If a service specification is available, the
maximum speed is limited according to the
speed index in the service specification.
Example: 245/40 ZR18 97 Y. In this
example, "97 Y" is the service specification.
The letter "Y" represents the speed index
and the maximum speed of the tire is
limited to 186 mph (300 km/h).
REvery tire that has a maximum speed above
186 mph (300 km/h) must have "ZR" in the
size description and the service
specification must be given in brackets.
Example: 275/40 ZR 18 (99 Y). The speed
index "(Y)" shows that the maximum speed
of the tire is above 186 mph (300 km/h).
Ask the tire manufacturer to find out the
maximum speed.

Observe the "Important safety notes"
(Y page 350).

! For safety reasons, Mercedes-Benz
recommends that you only use tires,
wheels and accessories which have been
approved by Mercedes-Benz specifically
for your vehicle.
These tires have been specially adapted for
use with the control systems, such as ABS
or ESP®, and are marked as follows:
RMO

= Mercedes-Benz Original
RMOE = Mercedes-Benz Original Extended
(tires with run-flat characteristics)
RMO1 = Mercedes-Benz Original (only
certain AMG tires)
Mercedes-Benz Original Extended tires
may only be used on wheels that have been
specifically approved by Mercedes-Benz.
Only use tires, wheels or accessories
tested and approved by Mercedes-Benz.
Certain characteristics, e.g. handling,
vehicle noise emissions or fuel
consumption, may otherwise be adversely
affected. In addition, when driving with a
load, tire dimension variations could cause
the tires to come into contact with the
bodywork and axle components. This could
result in damage to the tires or the vehicle.

Mercedes-Benz accepts no liability for
damage resulting from the use of tires,
wheels or accessories other than those
tested and approved.
Further information about tires, wheels and
approved combinations can be obtained
from any authorized Mercedes-Benz
Center.

i The Tire and Loading Information placard
with the recommended tire pressures is
attached to the B-pillar on the driver's side.
Further information about driving at high
speeds or driving with vehicle loads that are
lighter than the maximum vehicle load can
be found in the tire pressure table on the
inside of the fuel filler flap. Check tire
pressures regularly, and only when the tires
are cold. Follow the tire manufacturer's
maintenance recommendations in the
vehicle document wallet.
Further information on recommended tire
pressures including tire pressures for specific
driving situations, see (Y page 352).

i Notes on the vehicle equipment – always
equip the vehicle:
Rwith tires of the same size on a given axle

(left/right)
Rwith the same type of tires at a given time

(summer tires, winter tires, MOExtended
tires)

i Vehicles featuring the MOExtended runflat system are not equipped with a TIREFIT
kit at the factory. It is therefore
recommended that you additionally equip
your vehicle with a TIREFIT kit if you mount
tires that do not feature run-flat properties,
e.g. winter tires. You can obtain a TIREFIT
kit from an authorized Mercedes-Benz
Center, for example.

i The following pages contain information
on approved wheel rims and tire sizes for
equipping your vehicle with winter tires.

Important safety notes
G Warning!

Gasoline and diesel fuels are highly flammable
and poisonous. They burn violently and can
cause serious injury.
Never allow sparks, flames or smoking
materials near gasoline or diesel fuel!
Turn off the engine before refueling.
Whenever you are around gasoline or diesel
fuel, avoid inhaling fumes and any skin or
clothing contact. Extinguish all smoking
materials.
Direct skin contact with fuels and the
inhalation of fuel vapors are damaging your
health.

If premium-grade unleaded gasoline is
unavailable and regular gasoline is used,
observe the following precautions:
Ronly

fill the fuel tank to half full with
regular unleaded gasoline and add the
rest as soon as possible with premiumgrade unleaded gasoline.
Rdo not drive at the maximum speed.
Ravoid sudden acceleration.
Rwhen the vehicle is carrying a light cargo,
e.g. two passengers without luggage, do
not allow the engine to rev above
3000 rpm.
Rwhen the vehicle is fully loaded or being
operated in mountainous terrain, do not
depress the accelerator pedal further
than 2/3 of the pedal travel.

octane number is the average value of the
Research Octane Number (RON) and Motor
Octane Number (MON): (RON + MON) / 2,
also known as knock resistance.
Reformulated Gasoline (RFG) and/or
unleaded gasoline with additives can be used
if the concentration of the additives in the fuel
does not exceed 10%, e.g.:
REthanol
RTAME
RETBE
RIPA
RTBA

For MTBE, the concentration should not
exceed 15%.
The concentration of methanol in gasoline
including other additives must not exceed 3%.
Using mixtures of methanol and ethanol is not
permitted. Gasohol, a mixture of 10% ethanol
and 90% unleaded gasoline can be used.
All of these mix fuels must fulfill the fuel
requirements, e.g.:
Rknock

Diesel engines – important safety
information
! Only use commercially available ULTRALOW SULFUR DIESEL FUEL (ULSD, 15 ppm
MAXIMUM SULFUR) that meets the
ASTM D975 standard. Failure to use
ULTRA-LOW SULFUR DIESEL FUEL (ULSD)
can severely damage the vehicle's exhaust
gas aftertreatment system.

! Do not fill the tank with gasoline. Do not
blend diesel fuel with gasoline or kerosene.
Otherwise, the fuel system and the engine
will be damaged. Damage resulting from
the use of gasoline or kerosene is not
covered by the Mercedes-Benz Limited
Warranty.
To prevent malfunctions, diesel fuel with
improved flow characteristics is available in

the winter months. Check with your fuel
retailer.
Information on the fuel grade can usually be
found on the gas pump. If the information
cannot be found on the gas pump, ask service
station personnel. For further information,
contact an authorized Mercedes-Benz Center
or visit http://www.mbusa.com (USA
only).
Diesel engines – Fuels containing biodiesel (FAME [fatty acid methyl ester])
Mercedes-Benz USA approves the use of B5
(ULSD with a maximum of up to five percent
by volume biodiesel) for all diesel engines
with common rail direct injection (CDI) and
BlueTEC.
Pure biodiesel and diesel fuels that contain a
higher percentage of biodiesel, e.g. B20, may
cause damage to the fuel system/engine and
are, therefore, not approved.
For further information, please ask the
service station personnel. The label on the
gas pump must indicate clearly that the B5
biodiesel blend meets the ULSD standard. If
the label is not clear, do not refuel the vehicle.
The Mercedes-Benz Limited Warranty does
not cover damages caused by the use of fuels
not meeting Mercedes-Benz approved fuel
standards.

Additives in gasoline
One of the major problems in engine design
is the creation of carbon deposits during the
process of burning fuel. Mercedes-Benz
recommends that you use fuel brands that
have the additives which prevent the build up
of carbon deposits.
If you use fuels without these additives for a
longer period of time, there may be a build up
of carbon deposits, especially on the inlet
valves and in the combustion chamber.
This could lead to engine running problems,
e.g.:
Rwarm-up
Runstable

hesitation
idle

vehicles.
Consult an authorized Mercedes-Benz Center
or visit http://www.mbusa.com (USA only)
to view a list of approved products. Observe
the instructions for use on the product label.
Do not mix other fuel additives with fuel. This
causes unnecessary costs and could damage
the engine.

DEF
Important safety notes
i For BlueTEC vehicles only.
AdBlue® is a non-flammable, non-toxic,
colorless, odorless and water-soluble fluid.

! Only use AdBlue® that complies with
ISO 22241. Do not add any special
additives to AdBlue® and do not thin
AdBlue® with water. This could destroy the
BlueTEC exhaust gas aftertreatment.

! Rinse surfaces that have come into
contact with AdBlue® immediately with
water or remove AdBlue® using a damp
cloth and cold water. If the AdBlue® has
already crystallized, use a sponge and cold
water to clean it. AdBlue® residues

crystallize after time and contaminate the
affected surfaces.

High outside temperatures
If AdBlue® is heated to above 122 ‡ (50 †)
for an extended period of time, e.g. due to
direct sunlight on the AdBlue® tank,
AdBlue® may start to decompose. Ammonia
vapors develop as a result.

G Warning!

When opening the filler cap of the AdBlue®
tank ammonia gas vapors may escape. Refill
AdBlue® in a well ventilated area only.
Ammonia gas vapors have a pungent odor and
are particularly irritating for your skin,
mucous membranes, and eyes. Inhaling
ammonia gas vapors will cause burning eyes,
nose, and throat, as well as coughing and
watering eyes.

Low outside temperatures
AdBlue® freezes at a temperature of
approximately 12 ‡ (-11 †). The vehicle is
equipped with an AdBlue® preheating system
at the factory. Winter operation can thus be
guaranteed even at temperatures below
12 ‡ (-11 †).

Additives
! Use only AdBlue® complying with ISO
22241. Do not use any additives with
AdBlue® and do not thin AdBlue® with
water. This may destroy the BlueTEC
exhaust gas aftertreatment system.
Damage resulting from the use of additives
or water is not covered by the MercedesBenz Limited Warranty.

Purity
Assuring the purity of AdBlue® is particularly
important with respect to avoiding
malfunctions in the exhaust gas
aftertreatment system.

Service products and capacities
If AdBlue® is pumped out of the AdBlue® tank,
e.g. during repair work, it must not be
returned to the tank. The purity of the fluid
can no longer be guaranteed.

! Impurities in

AdBlue®,

e.g. due to other
service products, cleaning agents or dust,
lead to increased emission values, system
malfunctions, catalytic converter damage
or damage to the BlueTEC system.

Engine oil
i MB Approval is stated on the containers.

The engine oils are matched to the
performance of Mercedes-Benz engines and
service intervals. For this reason, only use
engine oils and oil filters that are approved for
vehicles with a service system.
Contact an authorized Mercedes-Benz Center
or visit http://www.mbusa.com (USA only)
for a list of approved engine oils and oil filters.

Lubricant additives

! Never use engine oil or an oil filter of a

Engine oil viscosity

specification other than is necessary to
fulfill the prescribed service intervals. Do
not change the engine oil or oil filter in
order to achieve longer replacement
intervals than those prescribed. Otherwise,
you may cause damage to the engine or
exhaust gas aftertreatment; this is not
covered by the Mercedes-Benz Limited
Warranty.
Follow the instructions in the service
interval display regarding the oil change.
Otherwise, you may damage the engine and
the exhaust gas aftertreatment.
Mercedes-Benz recommends MOBIL OIL.
The table shows which engines oil have been
approved for your vehicle.

52 USA

! Do not mix any lubricant additives with
the engine oil. This could damage the
engine. Damage resulting from the use of
such lubricant additives in the engine oil is
not covered by the Mercedes-Benz Limited
Warranty.

Viscosity describes the flow characteristics
of a fluid. If an engine oil has a high viscosity,
this means that it is thick; a low viscosity
means that it is thin.
Using the table below, make sure that the SAE
classification (viscosity) is sufficient for the
temperatures at which the vehicle is
operated. The low temperature
characteristics of engine oils can deteriorate
significantly, e.g. by aging, soot and fuel
deposits. It is therefore recommended that
you carry out oil changes regularly using an
approved engine oil with the appropriate SAE
classification.

mineral lubricants. Otherwise, you could
damage the air-conditioning system.

Brake fluid
G Warning!

The brake fluid constantly absorbs moisture
from the air; this lowers its boiling point.
If the boiling point of the brake fluid is too low,
vapor pockets may form in the brake system
when the brakes are applied hard (e.g. when
driving downhill). This would impair braking
efficiency.
You should have the brake fluid renewed at
regular intervals. The brake fluid change
intervals can be found in the Service Booklet.

Only use brake fluid approved by MercedesBenz. Information about approved brake
fluids can be obtained from any authorized
Mercedes-Benz Center.

! Only add coolant that has been premixed
with the desired antifreeze protection. You
could otherwise damage the engine.
Further information on coolants and on
filling can be found in the Mercedes-Benz
Specifications for Service Products, MB
Approval 310.1, e.g. on the Internet at
http://bevo.mercedes-benz.com. You
can also consult an authorized MercedesBenz Center.

! Always use a suitable coolant mixture,
even in countries where high temperatures
prevail.
Otherwise, the cooling system will not be
sufficiently protected from corrosion, and
the boiling point will be too low.
If the coolant has antifreeze protection down
to -35 ‡ (-37 †), the boiling point of the
coolant in the pressurized system is
approximately 266 ‡ (130 †).
Your vehicle has a range of aluminum
components. Use of aluminum components
in the engine make it necessary to specifically
match the antifreeze/corrosion inhibitor in
these systems in order to protect the
aluminum parts. Using other antifreeze/
corrosion inhibitors without these
characteristics affects the service life.
The coolant must be used throughout the year
in order to maintain the necessary corrosion
protection and provide protection from

overheating. In the Service Booklet, you can
find information on the intervals for renewal.
The renewal interval is determined by the
coolant type and the cooling system design.
The renewal interval in the Service Booklet is
only valid if the coolant is added or renewed
with Mercedes-Benz approved products.
Therefore, only use MB 326.0 antifreeze/
corrosion inhibitor or another Mercedes-Benz
approved product of the same specification.
Information on other Mercedes-Benz
approved products of the same specification
can be obtained at any authorized MercedesBenz Center or on the Internet at
http://bevo.mercedes-benz.com.
The coolant is checked at every service date
at an authorized Mercedes-Benz Center.
The antifreeze/corrosion inhibitor
concentration in the cooling system should:
Rbe at least 50%. This will protect the cooling

system against freezing down to around
-35 ‡ (-37 †).
Rnot exceed 55% (antifreeze protection
down to -49 ‡ (-45 †); otherwise, heat will
not be dissipated as effectively.
If the coolant level is too low, MB 326.0
antifreeze/corrosion inhibitor should be
added. Have the cooling system checked for
leaks.
