Power seats, front
Warning!

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.

When leaving the vehicle always remove the
electronic key from the steering lock, and lock your
vehicle.

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

The power seats can also be operated with the
driver’s or passenger door open. Do not leave
children unattended in the vehicle or with access
to an unlocked vehicle. Unsupervised use of vehicle
equipment may cause serious personal injury.
To operate the front power seat adjustment switches,
turn electronic key in steering lock to position 1 or 2
(with the driver’s or passenger’s door open, the power
seats can also be operated with the electronic key
removed or in steering lock position 0).

Never place hands under seat or near any moving
parts while a seat is being adjusted.

Important!

Warning!

Prior to operating the vehicle, the driver should adjust
the seat height for proper vision as well as fore/aft
placement and backrest angle to insure adequate
control, reach, operation, and comfort. The head
restraint should also be adjusted for proper height. See
also airbag section on page 66 for proper seat
positioning.

Children 12 years old and under must never ride in
the front seat, except in a Mercedes-Benz
authorized BabySmartTM compatible child seat,
which operates with the BabySmartTM system
installed in the vehicle to deactivate the passenger
side front airbag when it is properly installed.
Otherwise they will be struck by the airbag when it
inflates in a crash. If this happens, serious or fatal
injury can result.

In addition, also adjust the steering wheel to ensure
adequate control, reach, operation, and comfort.
Both the inside and outside rear view mirrors should be
adjusted for adequate rearward vision.
Fasten seat belts. Infants and small children should be
seated in a properly secured restraint system that
complies with U.S. Federal Motor Vehicle Safety
Standard 213 and Canadian Motor Vehicle Safety
Standard 213.
All seat, head restraint, steering wheel, and rear view
mirror adjustments as well as fastening of seat belts
should be done before the vehicle is put into motion.

According to accident statistics, children are safer
when properly restrained in the rear seating
positions than in the front seating positions.
Infants and small children must ride in back seats
and be seated in an appropriate infant or child
restraint system, which is properly secured with
the vehicle’s seat belt, fully in accordance with the
child seat manufacturer’s instructions.
A child’s risk of serious or fatal injuries is
significantly increased if the child restraints are
not properly secured in the vehicle and the child is
not properly secured in the child restraint.

Seat belts and integrated restraint system

Warning!

Your vehicle is equipped with seat belts for all seats,
emergency tensioning retractors for the front seat belts,
dual front airbags, door mounted side impact airbags
and knee bolsters for driver and front passenger. Their
protective functions are designed to complement one
another.

Seat belts
Important!
Laws in most states and all Canadian provinces require
seat belt use.
All states and provinces require use of child restraints
that comply with U.S. Federal Motor Vehicle Safety
Standard 213 and Canadian Motor Vehicle Safety
Standard 213.
All child restraint systems are designed to be secured in
vehicle seats by lap belts or the lap belt portion of a lapshoulder belt.
For your safety and that of your passengers we strongly
recommend their use.

Index

Warning!

Failure to wear and properly fasten and position
your seat belt greatly increases your risk of
injuries and their likely severity in an accident.
You and your passengers should always wear seat
belts.
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.

Note:
For cleaning and care of the seat belts, see page 306.

In the same crash, the possibility for injury or
death is lessened if you are wearing your seat belt.

Seat belt nonusage warning system

position.
Warning!
USE SEAT BELTS PROPERLY.
• Seat 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 case of an accident.
• Each 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 airbag, front passenger airbag, door
mounted side impact airbags), “ETR” (seat belt
emergency tensioning retractors), and front
seat knee bolsters. The system is designed to
enhance the protection offered to properly
belted occupants in certain frontal (front
airbags) and side (side impact airbags) impacts
which exceed preset deployment thresholds.

Practical hints

Car care

Technical
data

62
• Never wear belts over rigid or breakable
objects in or on your clothing, such as
eyeglasses, pens, keys etc., as these might
cause injuries.
• Never wear the shoulder belt under your arm,
against your neck or off your shoulder. In a
crash, your body would move too far forward.
That would increase the chance of head and
neck injuries. The belt would also apply too
much force to the ribs or abdomen, which
could severely injure internal organs such as
your liver or spleen.
• Position the lap belt as low as possible on your
hips and not across the abdomen. If the belt is
positioned across your abdomen, it could cause
serious injuries in a crash.
• Each seat belt should never be used for more
than one person at a time. Do not fasten a seat
belt around a person and another person or
other objects.
• Belts should not be worn twisted. In a crash,
you wouldn’t have the full width of the belt to
manage impact forces. The twisted belt against
your body could cause injuries.

Index

• Pregnant women should also use a lapshoulder belt. The lap belt portion should be
positioned as low as possible on the hips to
avoid any possible pressure on the abdomen.

• Never place your feet on the instrument panel
or on the seat. Always keep both feet on the
floor in front of the seat.

A child’s risk of serious or fatal injuries is
significantly increased if the child restraints are
not properly secured in the vehicle and the child is
not properly secured in the child restraint.

Warning!
USE CHILD RESTRAINTS PROPERLY.
Children 12 years old and under must never ride in
the front seat, except in a Mercedes-Benz
authorized BabySmartTM compatible child seat,
which operates with the BabySmartTM system
installed in the vehicle to deactivate the passenger
front airbag when it is properly installed.
Otherwise they will be struck by the airbag when it
inflates in a crash. If this happens, serious or fatal
injury will result.

Supplemental restraint system (SRS)

Emergency tensioning retractor (ETR)

Airbags are intended as a supplement to seat belts.
Airbags alone cannot protect as well as airbags plus
seat belts in impacts for which the airbags were
designed to operate, and do not afford any protection
whatsoever in crashes for which the airbags are not
designed to deploy.

The seat belts for the front seats are equipped with
emergency tensioning retractors. These tensioning
retractors are located in each belt’s inertia reel and
become operationally ready with the electronic key in
steering lock position 1 or 2.
The emergency tensioning retractors are designed to
activate only when the seat belts are fastened during
frontal impacts exceeding the first threshold of the SRS
and in rear impacts exceeding a preset severity level.
They remove slack from the belts in such a way that the
seat belts fit more snugly against the body restricting its
forward movement as much as possible.

The SRS uses two crash severity levels (thresholds) to
activate either the emergency tensioning retractor (ETR)
or front airbag or both. Activation depends on the
direction and severity of the impact exceeding the
preset thresholds and whether the seat belt is fastened.
Seat belt fastened

In cases of other frontal impacts, angled impacts,
roll-overs, certain side impacts, or other accidents
without sufficient frontal or rear impact forces, the
emergency tensioning retractors will not be activated.
The driver and passengers will then be protected by the
fastened seat belts and inertia reel in the usual manner.

• first threshold exceeded: ETR activates
• second threshold exceeded: airbag also activates
Seat belt not fastened
• first threshold exceeded:
airbag activates, but not ETR

For seat belt and emergency tensioning retractor safety
guidelines see page 72.

Driver and front passenger systems operate
independently of each other.

Important!

The operational readiness of the airbag system is
verified by the indicator lamp “SRS” in the instrument
cluster when turning the electronic key in steering lock
to position 1 or 2. If no fault is detected, the lamp will go
out after approximately 4 seconds; after the lamp goes
out, the system continues to monitor the components
and circuitry of the airbag system and will indicate a
malfunction by coming on again. If the lamp does not
come on at all or if it fails to extinguish after
approximately 4 seconds or if it comes on thereafter,
a malfunction in the system has been detected.

3 Side impact airbag
The side impact airbags are located in the doors.
The most effective occupant restraint system yet
developed for use in production vehicles is the seat belt.
In some cases, however, the protective effect of a seat
belt can be further enhanced by an airbag.

The following system components are monitored or
undergo a self-check: crash-sensor(s), airbag ignition
circuits, front seat belt buckles, emergency tensioning
retractors, seat sensor.

In conjunction with wearing the seat belts, the driver
and front passenger airbags can provide increased
protection for the driver and front passenger in certain
frontal impacts exceeding preset thresholds. Door

Front airbags
The driver and front passenger front airbags are
designed to activate only in certain frontal impacts
exceeding a preset threshold.
The front passenger airbag deploys only if the front
passenger seat is occupied and the indicator lamp on
the center console is not illuminated.
Note:
Heavy objects on the front passenger seat can appear to
the “SRS” to indicate the presence of an occupant in
that seat which causes the passenger front airbag to
deploy in a crash exceeding the appropriate threshold.

Index

Side impact airbags

Important!

The side impact airbags are designed to activate only in
certain side impacts exceeding a preset threshold. Only
the side impact airbag on the impacted side of the
vehicle deploys.

Airbags are designed to activate only in certain
frontal (front airbags) impacts, or side (side impact
airbags) impacts which exceed preset thresholds.
Only during these types of impacts, if of sufficient
severity to meet the deployment thresholds, will
they provide their supplemental protection.

The side impact airbag for the front passenger deploys
only if the front passenger seat is occupied.

The driver and passenger should always wear their
seat belts, otherwise it is not possible for the airbags
to provide their intended supplemental protection.

Side impact airbags operate best in conjunction with a
properly positioned and fastened seat belt.
Note:

In cases of other frontal impacts, angled impacts,
roll-overs, other side impacts, rear collisions, or
other accidents in which the airbags are not
designed to deploy, the airbags will not be activated.
The driver and passenger will then be protected by
the fastened seat belts.

Heavy objects on front passenger seat can cause the
side impact airbag to deploy in a crash.

We caution you not to rely on the presence of the
airbags in order to avoid wearing your seat belt.

Airbags are designed to reduce the potential of
injury in certain frontal (front airbags) impacts,
and side (side impact airbags) impacts which may
cause significant injuries, however, no system
available today can totally eliminate injuries and
fatalities.
The activation of the “SRS” temporarily releases a
small amount of dust from the airbags. This dust,
however, is neither injurious to your health, nor
does it indicate a fire in the vehicle. The dust might
cause some temporary breathing difficulty for
people with asthma or other breathing trouble. To
avoid this, you may wish to get out of 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
airbag inflates, then get fresh air by opening a
window or door.

Your vehicle was originally equipped with airbags
which are designed to activate in certain impacts
exceeding a preset threshold to reduce the potential
and severity of injury. It is important to your safety
and that of your passengers that you replace
deployed airbags and repair any malfunctioning
airbags to ensure the vehicle will continue to
provide crash protection for occupants.
Warning!
To reduce the risk of injury when the front airbags
inflate, it is very important for the driver and front
passenger to always be in a properly seated
position and to wear their seat belts.
For maximum protection in the event of a collision
always be in normal seated position with your back
against the backrest. Fasten your seat belt and
ensure that it is properly positioned on your body.
Since the airbag inflates with considerable speed
and force, a proper seating and hands on steering
wheel position will help to keep you at a safe
distance from the airbag. Occupants who are
unbelted, out of position or too close to the airbag
can be seriously injured by an airbag as it inflates
with great force in the blink of an eye:

Index

• Sit properly belted in an upright position with
your back against the backrest.

• Occupants, especially children, should never
lean their heads in the area of the door where
the side airbag inflates. This could result in
serious injuries or death should the airbag be
triggered. Always sit upright, properly use the
seat belts, and appropriate size infant or child
restraint system.

• Adjust the driver seat as far as possible
rearward, still permitting proper operation of
vehicle controls. The distance from the center
of the driver’s breastbone to the center of the
airbag cover on the steering wheel must be at
least ten inches (25 cm) or more. You should be
able to accomplish this by a combination of
adjustments to the seat and steering wheel. If
you have any problems, please see your
authorized Mercedes-Benz Center.

• Children 12 years old and under must never
ride in the front seat, except in a
Mercedes-Benz authorized BabySmart TM
compatible child seat, which operates with the
BabySmartTM system installed in the vehicle to
deactivate the passenger front airbag when it
is properly installed. Otherwise they will be
struck by the airbag when it inflates in a crash.
If this happens, serious or fatal injury can
result.

• Do not lean with your head or chest close to the
steering wheel or dashboard.
• Keep hands on the outside of steering wheel
rim. Placing hands and arms inside the rim
can increase the risk and potential severity of
hand/arm injury when the driver front airbag
inflates.

Failure to follow these instructions can result in
severe or fatal injuries to you or other occupants.

• Adjust the front passenger seat as far as
possible rearward from the dashboard when
the seat is occupied.

Warning!
Accident research shows that the safest place for
children in an automobile is in the rear seat.
Should you choose to place a child 12 years old or
under in the front passenger seat of your vehicle,
you must properly use a BabySmartTM child
restraint which will turn off the passenger side
front airbag. BabySmartTM will not, however, turn
off the passenger’s side impact airbag.
It should be noted however that there is a
possibility for a side airbag related injury if
occupants, especially children, are not properly
seated or restrained when next to a side airbag
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) occupants, especially
children, should never place their bodies or lean
their heads in the area of the door where the side
airbag inflates. This could result in serious
injuries or death should the side airbag be
activated; (2) always sit upright, properly use the
seat belts and use an appropriately sized infant or
child restraint system for all children 12 years old
or under; and (3) always wear seat belts properly.

Safety guidelines for the seat belt,
emergency tensioning retractor and airbag
Warning!
• Damaged seat belts or belts that were highly
stressed in an accident must be replaced and
their anchoring points must also be checked.
Use only belts installed or supplied by an
authorized Mercedes-Benz Center.
• Do not pass belts over sharp edges.
• Do not make any modification that could
change the effectiveness of the belts.
• Airbags and ETR’s are designed to function on
a one-time-only basis. An airbag or emergency
tensioning retractor (ETR) that was activated
must be replaced.

Index

• No modifications of any kind may be made to
any components or wiring of the “SRS”. This
includes changing or removing any component
or part of the “SRS”, the installation of
additional trim material, badges etc. over the
steering wheel hub, front passenger airbag
cover, or front door trim panels, and
installation of additional electrical/electronic
equipment on or near “SRS” components and
wiring. Keep area between airbags and
occupants free of objects (e.g. packages,
purses, umbrellas, etc.).

• For your protection and the protection of
others, when scrapping the airbag unit or
emergency tensioning retractor, our safety
instructions must be followed. These
instructions are available at your authorized
Mercedes-Benz Center.
• Given the considerable deployment speed and
the textile structure of the airbags, there is the
possibility of abrasions or other injuries
resulting from airbag deployment.
When you sell the vehicle we strongly urge you to give
notice to the subsequent owner that it is equipped with
an “SRS” by alerting him to the applicable section in the
Operator’s Manual.

• An airbag system component within the
steering wheel gets hot after the airbag has
inflated. Do not touch.
• Improper work on the system, including
incorrect installation and removal, can lead to
possible injury through an unintended
activation of the “SRS”.
• In addition, through improper work there is
the risk of rendering the “SRS” inoperative or
causing unintended airbag deployment. Work
on the “SRS” must therefore only be performed
by an authorized Mercedes-Benz Center.

Infant and child restraint systems

Important!

We recommend all infants and children be properly restrained at all times while the vehicle is in motion. All
lap-shoulder belts except the driver’s seat belt have
special seat belt retractors for secure fastening of child
restraints.

The use of infant or child restraints is required by law in
all 50 states and all Canadian provinces.

To activate, pull shoulder belt out completely and let it
retract. During the seat belt retraction a ratcheting
sound can be heard to indicate that the special seat belt
retractor is activated. The belt is now locked.
To deactivate, release seat belt buckle and let seat belt
retract completely. The seat belt can again be used in
the usual manner.
Warning!
Never release the seat belt buckle while vehicle is
in motion, since the special seat belt retractor will
be deactivated.

Infants and small children should be seated in an
appropriate infant or child restraint system properly
secured by a lap-shoulder belt, and that complies with
U.S. Federal Motor Vehicle Safety Standard 213 and
Canadian Motor Vehicle Safety Standard 213.
A statement by the child restraint manufacturer of
compliance with this standard can be found on the
instruction label on the restraint and in the instruction
manual provided with the restraint.
When using any infant or child restraint system, be sure
to carefully read and follow all manufacturer’s
instructions for installation and use.
Please read and observe warning labels affixed to inside
of vehicle and to infant or child restraints.

Index

Warning!

Children 12 years old and under must never ride in
the front seat, except in a Mercedes-Benz
authorized BabySmartTM compatible child seat,
which operates with the BabySmartTM system
installed in the vehicle to deactivate the passenger
front airbag when it is properly installed.
Otherwise they will be struck by the airbag when it
inflates in a crash. If this happens, serious or fatal
injury can result.

When the child restraint is not in use, remove it
from the vehicle or secure it with the seat belt to
prevent the child restraint from becoming a
projectile in the event of an accident.

According to accident statistics, children are safer
when properly restrained in the rear seating
positions than in the front seating positions.
Infants and small children must ride in back seats
and be seated in an appropriate infant or child
restraint system, which is properly secured with

Electrolyte has an irritating effect. Do not allow the
liquid come into contact with eyes, skin, clothing,
or respiratory system. In cases it does, immediately
flush affected area with water, and seek medical
help if necessary.
Important!
Electrolyte drops coming into contact with the vehicle
paint finish can only be completely removed while in
their liquid state, by applying plenty of water.

Coolant temperature gauge (3)

Outside temperature indicator (5)

During severe operating conditions and stop-and-go city
traffic, the coolant temperature may rise close to the red
marking.

The temperature sensor is located in the front bumper
area. Due to its location, the sensor can be affected by
road or engine heat during idling or slow driving. This
means that the accuracy of the displayed temperature
can only be verified by comparison to a thermometer
placed next to the sensor, not by comparison to external
displays (e.g. bank signs etc.).

The engine should not be operated with the coolant
temperature in the red zone. Doing so may cause
serious engine damage which is not covered by the
Mercedes-Benz Limited Warranty.
Warning!
• Driving when your engine is badly 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 and can occur just by opening
the engine hood. Stay away from the engine if
you see or hear steam coming from it.
Turn off the engine, get out of the vehicle and do
not stand near the vehicle until it cools down.

Adaptation to ambient temperature takes place in steps
and depends on the prevailing driving conditions (stopand-go or moderate, constant driving) and amount of
temperature change.
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.

engine damage that is not covered by the
Mercedes-Benz Limited Warranty.

steering wheel repeatedly until the trip odometer
appears if it is not displayed. See page 92.

Notes:
When disconnecting vehicle battery for one or more
days at a time, such days will not be counted. Any such
days not counted by the FSS can be added by your
Mercedes-Benz Center.
The interval between services is determined by the type
of driving for which the vehicle is used. For example,
driving at extreme speeds, and cold starts combined
with short distance driving in which the engine does not
reach operating normal temperature, reduce the interval
between services.

Index

Following a completed A or B service the
Mercedes-Benz Center sets the counter mileage to
10 000 miles (Canada: 15 000 km) and 365 days.

Operating safety

Audio and telephone, operation
These instructions are intended to help you become
acquainted with your Mercedes-Benz vehicle radio.
They contain useful tips and a detailed description of
the user functions.

Warning!
Any alternations made to electronic components
can cause malfunctions.
The radio, cassette deck, CD changer1 and
telephone1 are interconnected. Therefore, when
one of the components is defective or has not been
removed/replaced properly this may impair the
function of other components.

Warning!
In order to avoid distraction which could lead to an
accident, system settings should be entered with
the vehicle at standstill and systems should be
operated by the driver only when traffic conditions
permit. Always pay full attention to traffic
conditions first before operating system controls
while driving.

These malfunctions might seriously impair the
operating safety of your vehicle.
We recommend that you have any service work or
alternations on electronic components done in an
authorized Mercedes-Benz Center.

Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is covering
a distance of approximately 50 feet (approximately
14 m) every second.

The soft top should not be lowered or raised at outside
temperatures below +5°F (-15°C), since the material
becomes less pliable with lower temperatures.

• do not permit luggage/cargo to raise the closed
luggage cover,

Notes:

• do not load anything on top of the luggage cover,
• do not place anything on the soft top compartment
cover,
• do not open the trunk lid while the soft top is being
raised or lowered. This is required since the soft top
compartment cover moves upward and backward
during raising or lowering operations,

Rear passengers should lean forward while raising or
lowering the soft top, to clear the path of the rear
window.
To prevent the soft top from being lowered
unintentionally while a trunk luggage carrier is
installed, keep luggage cover in trunk in the open
position with the soft top raised.

Control and operation of radio transmitters
COMAND, radio and telephone

Telephones and two-way radio

Warning!

Please do not forget that your primary
responsibility is to drive the vehicle. Only operate
the COMAND (Cockpit Management and Data
System), radio or telephone 1 if road and traffic
conditions permit.

Never operate radio transmitters equipped with a
built-in or attached antenna (i.e. without being
connected to an external antenna) from inside the
vehicle while the engine is running. Doing so could
lead to a malfunction of the vehicle’s electronic
system, possibly resulting in an accident and
personal injury.

Bear in mind that at a speed of just 30 mph
(approximately 50 km/h), your vehicle is covering
a distance of approximately 50 feet (approximately
14 m) every second.
1 Observe all legal requirements.

Radio transmitters, such as a portable telephone or a
citizens band unit should only be used inside the
vehicle if they are connected to an antenna that is
installed on the outside of the vehicle.
Refer to the radio transmitter operation instructions
regarding use of an external antenna.

The first 1 000 miles (1 500 km)

Maintenance

The more cautiously you treat your vehicle during the
break-in period, the more satisfied you will be with its
performance later on. Therefore, drive your vehicle
during the first 1 000 miles (1 500 km) at moderate
vehicle and engine speeds.

Approximately 30 days or 2 000 miles ( 2000 km) prior
to the next recommended service, the remaining
distance or days are displayed in the multifunction
indicator. See Flexible service system (FSS) on
page 109.

During this period, avoid heavy loads (full throttle
driving) and excessive engine speeds.

We strongly recommend that you have your vehicle
serviced by your authorized Mercedes-Benz Center, in
accordance with the Service Booklet at the times called
for by the FSS.

Avoid accelerating by kickdown. It is not recommended
to brake the vehicle by manually shifting to a lower gear.
We recommend that you select positions “3”, “2” or “1”
only at moderate speeds (for hill driving).

Failure to have the vehicle maintained in accordance
with the Service Booklet at the designated times/
mileage may result in vehicle damage not covered by
the Mercedes-Benz Limited Warranty.

After 1 000 miles (1 500 km) speeds may be gradually
increased to the permissible maximum.

Check regularly and before a long trip, see page 226.

Catalytic converter

Caution!

Your Mercedes-Benz is equipped with monolithic type
catalytic converters, an important element in
conjunction with the oxygen sensors to achieve
substantial control of the pollutants in the exhaust
emissions. Keep your vehicle in proper operating
condition by following our recommended maintenance
instructions as outlined in your Service Booklet.

To prevent damage to the catalytic converters, use only
premium unleaded gasoline in this vehicle.
Any noticeable irregularities in engine operation should
be repaired promptly. Otherwise, excessive unburned
fuel may reach the catalytic converter causing it to
overheat, which could start a fire.
Warning!
As with any vehicle, do not idle, park or operate
this vehicle in areas where combustible materials
such as grass, hay or leaves can come into contact
with the hot exhaust system, as these materials
could be ignited and cause a vehicle fire.

Index

Emission control

Warning!

Certain systems of the engine serve to keep the toxic
components of the exhaust gases within permissible
limits required by law.

Inhalation of exhaust gas is hazardous to your
health. All exhaust gas contains carbon monoxide,
and inhaling it can cause unconsciousness and
lead to death.

These systems, of course, will function properly only
when maintained strictly according to factory
specifications. Any adjustments on the engine should,
therefore, be carried out only by qualified MercedesBenz authorized center technicians. Engine adjustments
should not be altered in any way. Moreover, the
specified service jobs must be carried out regularly
according to Mercedes-Benz servicing requirements.
For details refer to the Service Booklet.

Emission control
Instruments
and controls

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.

Starting and turning off the engine

Important!

Before starting

Due to the installed starter non-repeat feature, the
electronic key must be turned completely to the left
before attempting to start the engine again.

Ensure that parking brake is engaged and that selector
lever is in position “P” or “N”. Turn electronic key in
steering lock to position 2.
Starting

In areas where temperatures frequently drop below -4°F
(-20°C) we recommend that an engine block heater be
installed. Your authorized Mercedes-Benz Center will
advise you on this subject.

Do not depress accelerator.

Turning off

Briefly turn electronic key in steering lock clockwise to
the stop and release. The starter will engage until the
engine is running.

Turn the electronic key in the steering lock to position 0
to stop the engine.

If engine will not run, and the starting procedure stops,
turn electronic key completely to the left and repeat
starting the engine.
After several unsuccessful attempts, have the system
checked at the nearest authorized Mercedes-Benz
Center.

The electronic key can only be removed with the
selector lever in position “P”.

Automatic transmission

The automatic transmission selects individual gears
automatically, dependent upon
• Selector lever position
• Program mode selector
• Accelerator position
• Vehicle speed
The gear shifting process is continuously adapted,
dependent on the driving style, the driving situation
and the road characteristics.
Important!
When parking the vehicle or before working on the
vehicle with the engine running, firmly depress the
parking brake pedal and shift the selector lever into “P”.

Driving

Important!

The selector lever is automatically locked while in
position “P”. To move the selector lever out of
position “P”, the service brake pedal must be firmly
depressed before the shift lock will release.

After selecting any driving position from “N” or “P”,
wait a moment to allow the gear to fully engage before
accelerating, especially when the engine is cold.

Shift selector lever to the desired position only when the
engine is idling normally and the service brake is
applied. Do not release the brake until ready to drive.
The vehicle may otherwise start creeping when the
selector lever is in drive or reverse position.

Accelerator position

Warning!
It is dangerous to shift the selector lever out of “P”
or “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.

Partial throttle = early upshifting = normal acceleration
Full throttle = later upshifting = rapid acceleration
Kickdown (depressing the accelerator beyond full
throttle) = downshifting to a lower gear = maximum
acceleration. Once the desired speed is attained, ease up
on the accelerator – the transmission shifts up again.

Index

Stopping

Rocking a vehicle free in this manner may cause the
ABS or traction system malfunction indicator lamp to
come on. Turn off and restart the engine to clear the
malfunction indication.

For brief stops, e.g. at traffic lights, leave the
transmission in gear and hold vehicle with the service
brake.
For longer stops with the engine idling, shift into “N”
or “P” and hold the vehicle with the service brake.

Warning!

When stopping the vehicle on an uphill gradient, do not
hold it with the accelerator, use the brake. This avoids
unnecessary transmission heat build up.

Getting out of your vehicle with the selector lever
not fully engaged in position “P” is dangerous.
Also, when parked on an incline, position “P” alone
may not prevent your vehicle from moving,
possibly hitting people or objects.

Maneuvering

Always set the parking brake in addition to shifting
to position “P”, see page 204 for parking brake.

To maneuver in tight areas, e.g. when pulling into a
parking space, control the vehicle speed by gradually
releasing the brakes. Accelerate gently and never
abruptly step on the accelerator.

When parked on an incline, also turn front wheel
against curb.
Warning!

To rock a vehicle out of soft ground (mud or snow),
alternately shift from forward to reverse, while applying
slight partial throttle.

Park position
The park position is to be used when parking the
vehicle. Engage only with the vehicle stopped.
The park position is not intended to serve as a
brake when the vehicle is parked. Rather, the
driver should always use the parking brake in
addition to placing the selector lever in park to
secure the vehicle.
Note:
The electronic key can only be removed from the
steering lock with the selector lever in
position “P”. With the electronic key removed, the
selector lever is locked in position “P”.

The current selector lever position is indicated in the
gear range indicator display. The automatic gear
shifting process can be adapted to specific operating
conditions using the selector lever.

With a malfunction in the vehicle’s electrical
system the selector lever could remain locked in
position “P”. To unlock the selector lever
manually, see page 279.
Reverse gear
Shift to reverse gear only with the vehicle
stopped.

Index

Gear selection for special circumstances

Dependent on the program mode selector switch
position “S” or “W” the maximum speed in the
reverse gear is different. However, it is not
possible to change the program mode while in
reverse.

The transmission gear ranges for special circumstances
can be selected by pressing the selector lever to the
right or the left with the selector lever in position “D”.
The gear range currently selected is indicated in the
instrument cluster display.

Neutral
No power is transmitted from the engine to the
drive axle. When the brakes are released, the
vehicle can be moved freely (pushed or towed). Do
not engage “N” while driving except to coast
when the vehicle is in danger of skidding (e.g. on
icy roads, see winter driving instructions on
page 211).

Briefly press selector lever in the ç direction:
The transmission downshifts, one gear at a time, in the
order “4”, “3”, “2”, “1”.
Press and hold selector lever in the ç direction:
The selector lever position display will switch to the
gear range currently selected by the automatic
transmission.
The transmission will only shift down one gear if the
gear range currently selected has already shifted to its
highest possible gear.

Important!
Coasting the vehicle, or driving for any other
reason with selector lever in “N” can result in
transmission damage that is not covered by the
Mercedes-Benz Limited Warranty.

Briefly press selector lever in the æ direction:
The transmission will shift from the current gear range
to the next higher gear range. If the transmission is
already in gear range “D”, an additional upshift of one
gear is possible.

The transmission automatically upshifts through
5th gear. Position “D” provides optimum driving
characteristics under all normal operating
conditions.

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.
Important!
With transmission in gear range “D”, “4” or “3”,
upshifting from 1st to 2nd to 3rd gear is delayed
depending on vehicle speed and engine temperature.
This allows the catalytic converter to heat up more
quickly to operating temperatures.

Practical hints

Technical
data

200
During the brief warm-up period this delayed upshift
and increased engine noise might be perceived as a
malfunction. However, neither the engine nor
transmission are negatively affected by this mode of
operation.
The delayed upshift is effective with vehicle speeds
below 31 mph (50 km/h) at partial throttle and engine
temperatures below 95°F (35°C).
To avoid overrevving the engine when the selector lever
is moved to a lower gear range, the transmission will not
shift to a lower gear, if the engine’s revolutions per
minute limit would be exceeded. In this case there will
be no downshift, even when the vehicle speed reaches
the engine’s RPM limit of that gear, e.g. by applying the
service brakes.
To prevent the engine from laboring at low RPM when
driving uphill gradients or with your vehicle heavily
loaded, the automatic transmission will downshift when
necessary to maintain engine RPM within the best
torque range.

Index

Gear ranges:

Upshift through 2nd gear only. For driving in
mountainous regions or under extreme operating
conditions. This gear selection will allow use of
the engine’s braking power when descending
steep grades.

Upshift through 4th gear only. Suitable for
performance driving.
Upshift through 3rd gear only. Suitable for
moderately steep hills. Since the transmission
does not shift higher than 3rd gear, this gear
selection will allow use of the engine’s braking
power downhill.

Automatic transmission

Program mode selector switch

Accelerator Operation:
Fast on = depressing the accelerator pedal quickly
(not into kickdown position) while driving
continuously, rather than depressing the
accelerator pedal in the usual manner, will cause
the automatic transmission to shift down into a
lower gear. This gear shifting process is
dependent on the current vehicle speed.
Fast off = there will be no upshift when releasing
the accelerator pedal quickly, e.g. using the
engine’s braking power during performance
driving.

Winter/Wet (snow and ice) mode

The transmission is provided with a selector switch (1)
for Standard “S” and Winter/Wet (snow and ice) “W”
program modes.

Press switch on symbol “W”. The vehicle starts
out in 2nd gear, except with selector lever in 1st
gear, or with accelerator pedal in kick-down
position.

The “W” mode helps to improve traction and
driving stability of the vehicle.

Standard mode
Press switch on symbol “S”. Use this mode for all
regular driving.
The vehicle starts out in 1st gear.

The gear shifting process occurs at lower vehicle
and engine speeds than in the “S” program mode.

Index

Caution!

In this mode only the 2nd gear or reverse gear can be
activated.

Never change the program mode when the selector lever
is out of position “P”. It could result in a change of
driving characteristics for which you may not be
prepared.

To engage 2nd gear or reverse:
1. Stop the vehicle.
2. Move selector lever to position “P”.

Important!

3. Turn off the engine.

Always be certain of the program mode selected since
the vehicle driving characteristics change with the
selection of the program mode.

4. Wait approx. 10 seconds.
5. Restart the engine.

Dependent on the program mode selector switch
position “S” or “W” and the gear selector lever in
position “R”, the ratio of power transmission changes.

6. Move selector lever to position “D” (for 2nd gear), or
move selector lever to position “R” (for reverse gear).
Have the transmission checked at your authorized
Mercedes-Benz Center as soon as possible.

Emergency operation (Limp home mode)
If vehicle acceleration worsens or the transmission no
longer shifts, the transmission is most likely operating
in Limp home mode which engages when there is a
malfunction of the transmission. This condition may be
accompanied by the “CHECK ENGINE” malfunction
indicator lamp in the instrument cluster coming on.

Drinking and driving

Drive sensibly – save fuel

Warning!

Fuel consumption, to a great extent, depends on driving
habits and operating conditions.

Drinking or taking drugs and driving can be a very
dangerous combination. Even a small amount of
alcohol or drugs can affect your reflexes,
perceptions and judgement.

To save fuel you should:

The possibility of a serious or even fatal accident is
sharply increased when you drink or take drugs
and drive.

• keep tires at the recommended inflation pressures,
• remove unnecessary loads,
• allow engine to warm up under low load use,
• avoid frequent acceleration and deceleration,

Please don’t drink or take drugs and drive or allow
anyone to drive after drinking or taking drugs.

• have all maintenance work performed at regular
intervals by an authorized Mercedes-Benz Center.

Pedals

Fuel consumption is also increased by driving in cold
weather, in stop-and-go traffic, on short trips and in hilly
country.

The condition of the parking brake system is checked
each time the vehicle is in the shop for the required
maintenance service.

When the engine is not running, the brake and
steering systems are without power assistance.
Under these circumstances, a much greater effort is
necessary to stop or steer the vehicle.

If the parking brake is released and the brake warning
lamp in the instrument cluster stays on, the brake fluid
level in the reservoir is too low.

Brakes

Have the brake system inspected at an authorized
Mercedes-Benz Center immediately.

Warning!

All checks and service work on the brake system should
be carried out by an authorized Mercedes-Benz Center.

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 and increased pedal
pressure may be necessary to obtain expected
braking effect. Be sure to maintain a safe distance
from vehicles in front.
Resting your foot on the brake pedal will cause
excessive and premature wear of the brake pads.
It can also result in the brakes overheating thereby
significantly reducing their effectiveness. It may
not be possible to stop the vehicle in sufficient time
to avoid an accident.

Brake pad wear or a leak in the system may be the
reason for low brake fluid in the reservoir.

Install only brake pads and brake fluid recommended by
Mercedes-Benz.
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.

Index

Caution!

Parking

When driving down long and steep grades, relieve the
load on the brakes by shifting into a lower gear to use
the engine’s braking power. This helps prevent
overheating of the brakes and reduces brake pad wear.

Warning!
To reduce the risk of personal injury as a result of
vehicle movement, before turning off the engine
and leaving the vehicle, always:

After hard braking, it is advisable to drive on for some
time, rather than immediately parking, so the air stream
will cool down the brakes faster.

1. Keep right foot on the service brake pedal.
2. Firmly depress parking brake pedal.
3. Move the selector lever to position “P”.

Driving off

4. Slowly release the service brake pedal.

Apply the service brakes to test them briefly after
driving off. Perform this procedure only when the road
is clear of other traffic.

5. Turn front wheels towards the road curb.
6. Turn the electronic key to steering lock
position 0 and remove.

Warm up the engine smoothly. Do not place full load on
the engine until the operating temperature has been
reached.

7. Take the electronic key and lock vehicle when
leaving.

When starting off on a slippery surface, do not allow one
drive wheel to spin for an extended period with the ESP
switched off. Doing so may cause serious damage to the
drive train which is not covered by the Mercedes-Benz
Limited Warranty.

Important!
It is advisable to set the parking brake whenever
parking or leaving the vehicle. In addition, move
selector lever to position “P”.
When parking on hills, always set the parking brake.

Tires
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 roadway.
Inspect the tires and under the vehicle for possible
damage. If the vehicle or tires appear unsafe, have
it towed to the nearest Mercedes-Benz Center or
tire dealer for repairs.
Warning!

Tread wear indicators (TWI) are required by law. These
indicators are located in six places on the tread
circumference and become visible at a tread depth of
approximately 1/16 in (1.5 mm), at which point the tire is
considered worn and should be replaced.

Do not allow your tires to wear down too far. As
tread depth approaches 1/16 in (1.5 mm), the
adhesion properties on a wet road are sharply
reduced.

The tread wear indicator appears as a solid band across
the tread.

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

Index

Tire traction

Specified tire pressures must be maintained. This
applies particularly if the tires are subjected to high
loads (e.g. high speeds, heavy loads, high ambient
temperatures).

The safe speed on a wet, snow covered or icy road is
always lower than on a dry road.
You should pay particular attention to the condition of
the road whenever the outside temperatures are close to
the freezing point.

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 or driving at high speed with a flat tire will
cause excessive heat build-up and possibly a fire.

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.

Aquaplaning
Depending on the depth of the water layer on the road,
aquaplaning may occur, even at low speeds and with
new tires. Reduce vehicle speed, avoid track grooves in
the road and apply brakes cautiously in the rain.

Driving instructions
Instruments
and controls

Operation

We recommend M+S rated radial-ply tires for the winter
season for all four wheels to insure normal balanced
handling characteristics. On packed snow, they can
reduce your stopping distance as compared with
summer tires. Stopping distance, however, is still
considerably greater than when the road is not snow or
ice covered.

Tire speed rating

Snow chains

CLK 320:
Your vehicle is factory equipped with “H”-rated tires,
which have a speed rating of 130 mph (210 km/h).

Use only snow chains that are tested and recommended
by Mercedes-Benz. Your authorized Mercedes-Benz
Center will be glad to advise you on this subject.

CLK 430:
Your vehicle is factory equipped with “W”-rated tires,
which are permissible for speeds up to 168 mph
(270 km/h).

Chains should only be used on the rear wheels. Follow
the manufacturer’s mounting instructions.

An electronic speed limiter prevents your vehicle from
exceeding a speed of 130 mph (210 km/h).
Despite the tire rating, local speed limits should be
obeyed. Use prudent driving speeds appropriate to
prevailing conditions.

Snow chains should only be driven on snow covered
roads at speeds not to exceed 30 mph (50 km/h).
Remove chains as soon as possible when driving on
roads without snow.
When driving with snow chains, press the ESP control
switch to OFF, refer to page 222.
Important!

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 resulting in personal injury
and possible death.

Use of snow chains is not permissible with tire sizes
225/ 45 R17 and 245 /40 R17.

Winter driving instructions

If the vehicle is parked after being driven on salt treated
roads, the braking efficiency should be tested as soon as
possible after driving is resumed while observing the
safety rules in the previous paragraph.

The most important rule for slippery or icy roads is to
drive sensibly and to avoid abrupt acceleration, braking
and steering maneuvers. Do not use the cruise control
system under such conditions.

Warning!

When the vehicle is in danger of skidding, move
selector lever to position “N”. Try to keep the vehicle
under control by corrective steering action.

If the vehicle becomes stuck in snow, make sure
that snow is kept clear of the exhaust pipe and
from around the vehicle with engine running.
Otherwise, deadly carbon monoxide (CO) gases may
enter vehicle interior resulting in unconsciousness
and death.

Road salts and chemicals can adversely affect braking
efficiency. Increased pedal force may become necessary
to produce the normal brake effect. We therefore
recommend depressing the brake pedal periodically
when traveling at length on salt-strewn roads. This can
bring road salt impaired braking efficiency back to
normal. A prerequisite is, however, that this be done
without endangering other drivers on the road.

Winter driving
Have your vehicle winterized at your authorized
Mercedes-Benz Center before the onset of winter.
• Change the engine oil if the engine contains an oil
which is not approved for winter operation. For
viscosity (SAE/CCMC class) and filling quantity, see
page 317.
• Check engine coolant anticorrosion/antifreeze
concentration.
• Additive for the windshield washer and headlamp
cleaning system: Add MB Concentrate “S” to a
premixed windshield washer solvent/antifreeze
which is formulated for below freezing temperatures
see page 259.
• Test battery: Battery capacity drops with decreasing
ambient temperature. A well charged battery helps
to ensure that the engine can be started, even at low
ambient temperatures.
• Tires: We recommend M+S rated radial-ply tires on
all four wheels for the winter season. Observe
permissible maximum speed for M+S rated
radial-ply tires and the legal speed limit.

Practical hints

Car care

Technical
data

212
In winter operation, the maximum effectiveness of the
antilock brake system (ABS) or of the electronic stability
program (ESP) can only be achieved with M+S rated
radial-ply tires and/ or snow chains recommended by
Mercedes-Benz. Snow chains maximize performance.
For driving instructions with snow chains, see page 210.
Deep water
Caution!
Do not drive through flooded areas or water of unknown
depth.
If you must drive through deep water, drive slowly to
prevent water from entering the engine compartment or
passenger compartment, being ingested by the air
intake, possibly causing damage to electrical
components or wiring, to engine or transmission that is
not covered by the Mercedes-Benz Limited Warranty.
Block heater (Canada only)
The engine is equipped with a block heater.
The electrical cable may be installed at your authorized
Mercedes-Benz Center.

Traveling abroad
Abroad, there is a widely-spread Mercedes-Benz service
network at your disposal. If you plan to travel into areas
which are not listed in the index of your Mercedes-Benz
Center directory, you should request pertinent
information from your authorized Mercedes-Benz
Center.

Warning!
Always fasten items being carried as securely as
possible.
In an accident, during hard braking or sudden
maneuvers, loose items will be thrown around
inside the vehicle, and cause injury to vehicle
occupants unless the items are securely fastened in
the vehicle.
The trunk is the preferred place to carry objects.

Cruise control

1 Accelerate and set:
Lift lever briefly to set speed.
Hold lever up to accelerate.

2 Decelerate and set:
Depress lever briefly to set speed.
Hold lever down to decelerate.

Normally the vehicle is accelerated to the desired
speed with the accelerator.
4

The cruise control allows you to drive in a more relaxed
manner, for example over long distances, as it
automatically maintains the set speed by actively
regulating the throttle setting.
Any given speed above approximately 25 mph
(40 km/h) can be maintained with the cruise control by
operating the lever.

Speed is set by briefly pushing the lever to
position 1 or 2. The accelerator can then be
released.
The speed can be increased (e.g. for passing) by
using the accelerator. After the accelerator is
released, the previously set speed will be resumed
automatically.
If a set speed is to be increased or decreased
slightly, e. g. to adapt to the traffic flow, hold lever in
position 1 or 2 until the desired speed is reached, or
briefly tip the lever in the appropriate direction for
increases or decreases in 0.6 mph (1 km/h)
increments. When the lever is released, the newly
set speed remains.

Index

3 Canceling

Important!

To cancel the cruise control, briefly push lever to
position 3.

Moving gear selector lever to position “N” switches the
cruise control off.

When you step on the brake pedal or the vehicle
speed drops below approx. 25 mph (40 km/h), for
example when driving upgrade, the cruise control
will be canceled.

Warning!
Only use the cruise control if the traffic and
weather conditions make it advisable to travel at a
steady speed.

If the cruise control cancels by itself and remains
inoperative until the engine is restarted, have the
system checked at your authorized Mercedes-Benz
Center as soon as possible.

• The use of cruise control can be dangerous on
winding roads or in heavy traffic because
conditions do not allow safe driving at a steady
speed.

4 Resume

• The use of cruise control can be dangerous on
slippery roads. Rapid changes in tire adhesion
can result in wheel spin and loss of control.

If the lever is briefly pushed to position 4 when
driving at a speed exceeding approx. 25 mph
(40 km/h), the vehicle resumes the speed which
was set prior to the cancellation of the cruise
control. The last memorized speed is canceled when
the electronic key in the steering lock is turned to
position 1 or 0.

Driving systems
Instruments
and controls

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.

Notes:
If the engine does not brake the vehicle sufficiently
while driving on a downgrade, the speed you set on the
cruise control may be exceeded. In this case the
automatic transmission shifts down (max. to 3rd gear)
to maintain the set cruise control speed by using the
engine’s braking power.
As soon as the grade eases, the automatic transmission
shifts up again dependent on the selector lever position.
Nevertheless, in some cases you may have to step on the
brake pedal to slow down. In this case the cruise control
is switched off.
Use the lever to resume the previously set speed.

Brake assist system (BAS)
Warning!
BAS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase
braking efficiency beyond that afforded by the
condition of the vehicle brakes and tires or the
traction afforded. The BAS cannot prevent
accidents, including those resulting from excessive
speed in turns, following another vehicle too
closely, or aquaplaning. Only a safe, attentive, and
skillful driver can prevent accidents. The
capabilities of a BAS equipped vehicle must never
be exploited in a reckless or dangerous manner
which could jeopardize the user’s safety or the
safety of others.
The BAS is designed to maximize the vehicle’s braking
capability during emergency braking maneuvers by
having maximum power boost applied to the brakes
more quickly in emergency braking conditions than
might otherwise be afforded solely by the driver’s
braking style. This can help reduce braking distances
over what ordinary driving and braking style might do.
The BAS complements the antilock brake system (ABS).

Index

Applying the brakes very quickly results in maximum
BAS assistance.

If the charging voltage falls below 10 volts, the
malfunction indicator lamp comes on and the BAS is
switched off. When the voltage is above this value again,
the malfunction indicator lamp should go out and the
BAS is operational.

To receive the benefit of the system you must apply
continuous full braking power during the stopping
sequence. Do not reduce brake pedal pressure.

With the ABS malfunctioning, the BAS is also switched
off. Both malfunction indicator lamps come on with the
engine running.

Once the brake pedal is released, the BAS is deactivated.
The malfunction indicator lamp for the electronic
stability program (ESP) is combined with the BAS
malfunction indicator lamp.

If the BAS warning message is displayed, have the BAS
or ESP checked at your authorized Mercedes-Benz
Center as soon as possible.

The BAS/ESP malfunction indicator lamp in the
instrument cluster comes on with the electronic key in
steering lock position 2 and should go out with the
engine running.
If the BAS/ESP malfunction indicator lamp comes on
permanently while the engine is running, a malfunction
has been detected in either system. As a result, it is
possible that now only partial engine output will be
available. If the BAS malfunctions, the brake system
functions in the usual manner, but without BAS.

Antilock brake system (ABS)
Warning!
Do not pump the brake pedal, rather use firm,
steady brake pedal pressure. Pumping the brake
pedal defeats the purpose for ABS and significantly
reduces braking effectiveness.
Important!
The ABS improves steering control of the vehicle during
hard braking maneuvers.
The ABS prevents the wheels from locking up above a
vehicle speed of approximately 5 mph (8 km/h)
independent of road surface conditions.

Practical hints

Car care

Technical
data

218
At the instant one of the wheels is about to lock up, a
slight pulsation can be felt in the brake pedal,
indicating that the ABS is in the regulating mode. Keep
firm and steady pressure on the brake pedal while
experiencing the pulsation.
Continuous steady brake pedal pressure results in
applying the advantages of the ABS, namely braking
power and ability to steer the vehicle.
In the case of an emergency brake maneuver keep
continuous full pressure on the brake pedal. In this
manner only can the ABS be most effective.
On slippery road surfaces, the ABS will respond even
with light brake pedal pressure because of the
increased likelihood of locking wheels. The pulsating
brake pedal can be an indication of hazardous road
conditions and functions as a reminder to take extra
care while driving.

Index

ABS control

If the ABS malfunction indicator lamp stays illuminated,
have the system checked at your authorized
Mercedes-Benz Center as soon as possible.

The ABS malfunction indicator lamp - in the
instrument cluster comes on with the electronic key in
steering lock position 2 and should go out with the
engine running.

Warning!
ABS cannot prevent the natural laws of physics
from acting on the vehicle, nor can it increase
braking or steering efficiency beyond that afforded
by the condition of the vehicle brakes and tires or
the traction afforded. The ABS cannot prevent
accidents, including those resulting from excessive
speed in turns, following another vehicle too

skillful driver can prevent accidents. The
capabilities of an ABS equipped vehicle must never
be exploited in a reckless or dangerous manner
which could jeopardize the user’s safety or the
safety of others.

When the ABS malfunction indicator lamp in the
instrument cluster comes on while the engine is
running, it indicates that the ABS has detected a
malfunction and has switched off. In this case, the brake
system functions in the usual manner, but without
antilock assistance.
For ABS malfunction indicator lamp, see page 231.
With the ABS malfunctioning, the BAS and ESP are also
switched off. Both malfunction indicator lamps come on
with the engine running.
If the charging voltage falls below 10 volts, the
malfunction indicator lamp comes on and the ABS is
switched off. When the voltage is above this value again,
the malfunction indicator lamp should go out and the
ABS is operational.

The ESP enhances directional control and reduces
driving wheel spin of the vehicle under various driving
conditions.
Over/understeering of the vehicle is counteracted by
applying brakes to the appropriate wheel to create a
countervailing vehicle movement. Engine torque is also
limited. The ESP warning lamp, located in the
speedometer dial, starts to flash when ESP is in
operation.

Practical hints

Car care

Technical
data

220
Important!
If the ESP warning lamp v flashes:
• During take-off apply as little throttle as possible.
• While driving ease up on the accelerator.
• Adapt your speed and driving to the prevailing road
conditions.
• Do not switch off the ESP.
Caution!
If the vehicle is towed with the front axle raised (see
towing the vehicle on page 276), the engine must be
shut off (electronic key in steering lock position 0 or 1).
Otherwise, the ESP will immediately be engaged and
will apply the rear wheel brakes.

Index

Notes:

Driving the vehicle with varied size tires will cause the
wheels to rotate at different speeds, therefore the ESP
may activate (yellow ESP warning lamp in speedometer
dial comes on). For this reason, all wheels, including the
spare wheel, must have the same tire outside diameter.

The malfunction indicator lamp ¿ for the ESP is
combined with that of the BAS.
The yellow BAS/ESP malfunction indicator lamp in the
instrument cluster and the yellow ESP warning
lamp v in the speedometer dial come on with the
electronic key in steering lock position 2. They should
go out with the engine running.

When testing the parking brake on a brake test
dynamometer, the engine must be shut off. Otherwise,
the ESP will immediately be engaged and will apply the
rear wheel brakes.

If the BAS/ESP malfunction indicator lamp comes on
continuously with the engine running, a malfunction
has been detected in either system. Only partial engine
output will be available.

In winter operation, the maximum effectiveness of the
ESP is only achieved with Mercedes-Benz recommended
M+S rated radial-ply tires and/or snow chains.

If the BAS malfunctions, the brake system functions in
the usual manner, but without BAS.

Synchronizing ESP

If the ESP warning message is displayed, have the BAS
or ESP checked at your authorized Mercedes-Benz
Center as soon as possible.

If the power supply was interrupted (battery
disconnected or empty), the BAS/ESP malfunction
indicator lamp may be illuminated with the engine
running.

For ESP warning message, see page 245.

Turn steering wheel completely to the left and then to
the right. The BAS/ESP malfunction indicator lamp
should go out.

With the ABS malfunctioning, the ESP is also switched
off.

If one drive wheel loses traction and begins to spin, the
brake is applied until the wheel regains sufficient
traction. The traction control engages at vehicle speeds
up to approximately 24 mph (40 km/h), and switches off
at 50 mph (80 km/h).

Index

Note:

The ESP warning lamp, located in the speedometer dial,
starts to flash at any vehicle speed as soon as the tires
lose traction and the wheels begin to spin.

Avoid spinning of one drive wheel. This may cause
serious damage to the drive train which is not covered
by the Mercedes-Benz Limited Warranty.

To return to the enhanced vehicle stability offered by
ESP: press lower half of the switch (the ESP warning
lamp in the speedometer dial goes out).

Warning!
ESP should not be switched off during normal
driving other than in circumstances described
above. Disabling of the system will reduce vehicle
stability in standard driving maneuvers.

Important!

Checking engine oil level (CLK 320 shown)

Wipe oil dipstick clean prior to checking the engine oil
level. Fully insert dipstick in tube, and remove after
three seconds to obtain accurate reading.
Oil level must be between the
lower (min) and upper (max) mark of

To check the engine oil level, park vehicle on level
ground, with engine at normal operational temperature.
Check engine oil level approximately 5 minutes after
stopping the engine, allowing for the oil to return to the
oil pan.

Do not overfill the engine. Excessive oil must be drained
or siphoned. It could cause damage to engine and
catalytic converter not covered by the Mercedes-Benz
Limited Warranty.
See malfunction and warning messages on page 234 if
an engine oil level display appears on the multifunction

See your authorized Mercedes-Benz Center for further
information.
See your authorized Mercedes-Benz Center for
information on tested and recommended rims and tires
for summer and winter operation. They can also offer
advice concerning tire service and purchase.
Tire replacement
Front tires should be replaced in sets. Rims and tires
must be of the correct size and type. For dimensions,
see “Technical Data” (page 314).
We recommend that you break in new tires for approx.
60 miles (100 km) at moderate speed.

It is imperative that the wheel mounting bolts be
fastened to a tightening torque of 80 ft.lb. (110 Nm)
whenever wheels are mounted.
For rim and tire specifications, refer to “Technical Data”
(page 314).
Warning!
Worn, old tires can cause accidents. If the tire tread
is badly worn, or if the tires have sustained
damage, replace them.
When replacing rims, use only 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.

Index

Rotating wheels

Notes:

CLK 430:
Wheel rotation applies only when winter tires are
mounted on all four wheels.

Thoroughly clean the inner side of the wheels any time
you rotate the wheels or wash the vehicle underside.

The wheels can be rotated according to the degree of
tire wear while retaining the same direction of travel.

The use of retread tires is not recommended. Retread
tires may adversely affect the handling characteristics
and safety of the vehicle.

Rotating, however, should be carried out as
recommended by the tire manufacturer, before the
characteristic tire wear pattern (shoulder wear on front
wheels and tread center wear on rear wheels) becomes
visible, as otherwise the driving properties deteriorate.

Dented or bent rims can cause tire pressure loss and
damage to the tire beads. For this reason, check rims for
damage at regular intervals. The rim flanges must be
checked for wear before a tire is mounted. Remove
burrs, if any.

Important!

Check and ensure proper tire inflation pressure after
rotating the wheels. For tire inflation pressure see
inside of fuel filler flap and also page 271.

Unidirectional tires must always be mounted with arrow
on tire sidewall pointing in direction of vehicle forward
movement.

Tire inflation pressure

Tire pressures listed for light loads are minimum values
offering high driving comfort. Increased inflation
pressures for heavy loads produce favorable handling
characteristics with lighter loads and are perfectly
permissible. The ride of the vehicle, however, will
become somewhat harder.

A table (see fuel filler flap) lists the tire inflation
pressures specified for Mercedes-Benz recommended
tires as well as for the varying operating conditions.
Important!

Tire temperature and pressure increase with the vehicle
speed. Tire pressure should therefore only be checked
and corrected on cold tires. Correct tire pressure in
warm tires only if pressure has dropped below the
pressure listed in the table and the respective operating
conditions are taken into consideration.

Tire pressure changes by approx. 1.5 psi (0.1 bar) per
18°F (10°C) of air temperature change. Keep this in
mind when checking tire pressure inside a garage –
especially in the winter.
Example:
If garage temperature = approx. +68°F (+20°C) and
ambient temperature = approx. +32°F (0°C) then the
adjusted air pressure = specified air pressure +3 psi
(+0.2 bar).

Tires, Wheels
Instruments
and controls

An underinflated tire due to a slow leak (e.g. due to a
nail in the tire) may cause damage such as tread
separation, bulging etc.. Regular tire pressure checks
(including the spare tire) at intervals of no more than
14 days are therefore essential.

If a tire constantly loses air, it should be inspected for
damage.

Battery

The spare tire should be checked periodically for
condition and inflation. Spare tire will age and become
worn over time even if never used, and thus should be
inspected and replaced when necessary.

Warning!

Warning!
Do not overinflate tires. Overinflating tires can
result in sudden deflation (blowout) because they
are more likely to become punctured or damaged
by road debris, potholes etc.. Follow recommended
inflation pressures.
Do not overload the tires by exceeding the specified
vehicle capacity weight (as indicated by the label
on the driver’s door latch post). Overloading the
tires can overheat them, possibly causing a
blowout.

Failure to follow these instructions can result in
severe injury or death.
Never lean over batteries while connecting, you
might get injured.
Battery fluid contains sulfuric acid. Do not allow
this fluid to come in contact with eyes, skin or
clothing. In case it does, immediately flush affected
area with water and seek medical help if necessary.
A battery will also produce hydrogen gas, which is
flammable and explosive. Keep flames or sparks
away from battery, avoid improper connection of
jumper cables, smoking etc..
Important!
Battery replacement information:
The maintenance-free battery is located in the trunk
under the trunk floor.
The service life of the battery is dependent on its
condition of charge. The battery should always be kept
sufficiently charged, in order to last an optimum length
of time.

Index

Therefore, we strongly recommend that you have the
battery charge checked frequently, and corrected if
necessary, especially if you use the vehicle less than
approximately 200 miles (300 km) per month,
mostly for short distance trips, or if it is not used for
long periods of time.

Notes:
After reconnecting the battery also set the clock (see
page 106) resynchronize the front seats (see page 49),
front seat head restraints (see page 49), the express
feature of the power windows (see page 147), and the
electronic stability program (ESP) (see page 221).

Only charge a battery with a battery charger after the
battery has been disconnected from the vehicle’s
electrical circuit.

If the soft top is in a half open position, it also has to be
synchronized. To do so, raise and lock soft top manually
(see page 291).

Always disconnect the battery negative lead first and
connect last.

Battery recycling

When removing and connecting the battery, always
make sure that all electrical consumers are off and the
electronic key is in steering lock position 0. The battery
and its filler caps must always be securely installed
when the vehicle is in operation. During removal and
installation always protect the disconnected battery
positive (+) terminal with the cover attached to the
battery.

Batteries contain material that can harm the
environment with improper disposal.
Large 12 Volt storage batteries contain lead.
Recycling of batteries is the preferred method of
disposal.
Many states require sellers of batteries to accept old
batteries for recycling.

While the engine is running the battery terminal clamps
must not be loosened or detached, otherwise the
generator and other electronic components would be
damaged.

Important!
A discharged battery can freeze at approx. +14°F
(–10°C). In that case, it must be thawed out before
jumper cables are used. Attempting to jump start a
frozen battery can result in it exploding, causing
personal injury.
Jumper cable specifications:
• Minimum cable cross-section of 25 mm 2 or approx.
2 AWG
• Maximum length of 11.5 ft. (3.5 m).
If the battery is discharged, the engine should be started
with jumper cables and the (12 V) battery of another
vehicle.
Only use 12 V battery to jump start your vehicle. Jump
starting with more powerful battery could damage the
vehicle’s electrical systems, which will not be covered
by the Mercedes-Benz Limited Warranty.
The battery is located in the trunk under the trunk floor.

Index

Important!

Proceed as follows:
1. Position the vehicle with the charged battery so that
the jumper cables will reach, but never let the
vehicles touch. Make sure the jumper cables do not
have loose or missing insulation.

5. Start engine of the vehicle with the charged battery
and run at high idle. Make sure the cables are not
on or near pulleys, fans, or other parts that move
when the engine is started. Allow the discharged
battery to charge for a few minutes. Start engine of
the disabled vehicle in the usual manner.

2. On both vehicles:
• Turn off engine and all lights and accessories,
except hazard warning flashers or work lights.

6. After the engine has started, remove jumper cables
by exactly reversing the above installation
sequence, starting with the last connection made
first. When removing each clamp, make sure that it
does not touch any other metal while the other end
is still attached.

• Apply parking brake and shift selector lever to
position “P”.
Important!
3. Clamp one end of the first jumper cable to the
positive (+) under hood terminal of the discharged
battery and the other end to the positive (+) terminal
of the charged battery. Make sure the cable clamps
do not touch any other metal parts.

Notes:
If engine does not run after several unsuccessful
starting attempts, have it checked at the nearest
authorized Mercedes-Benz Center.
Excessive unburned fuel may damage the catalytic
converter.

4. Clamp one end of the second jumper cable to the
grounded negative (–) terminal of the charged
battery and the final connection to the negative (–)

We recommend that the vehicle be transported using
flat bed equipment. This method is preferable to other
types of towing.
The vehicle may be towed with all wheels on the ground
and the selector lever in position “N” for distances up to
30 miles (50 km) and at a speed not to exceed 30 mph
(50 km/h). The electronic key must be in steering lock
position 2.
To be certain to avoid a possibility of damage to the
transmission, however, we recommend the drive shaft
be disconnected at the rear axle drive flange for any
towing beyond a short tow to a nearby garage.
Do not tow with sling-type equipment. Towing with
sling-type equipment over bumpy roads will damage
radiator and supports.
Use wheel lift, dolly, or flat bed equipment, with
electronic key in steering lock turned to position 0.
Warning!
With the engine not running, there is no power
assistance for the braking and steering systems. In
this case, it is important to keep in mind that a
considerably higher degree of effort is necessary to
brake and steer the vehicle.

Note:
To signal turns while being towed with hazard warning
flasher in use, turn electronic key in steering lock to
position 2 and activate combination switch for left or
right turn signal in usual manner – only the selected
turn signal will operate.
Upon canceling the turn signal, the hazard warning
flasher will operate again.
Caution!
If the vehicle is towed with the front axle raised, the
engine must be shut off (electronic key in steering lock
position 0 or 1). Otherwise, the ESP will immediately be
engaged and will apply the rear wheel brakes. Switch off
the tow-away alarm (see page 44) as well as the ESP (see
page 222).

Cleaning and care of the vehicle
Cleaning and care of the vehicle
Warning!
Many cleaning products can be hazardous. Some
are poisonous, others are flammable. Always follow
the instructions on the particular container.
Always open your vehicle’s doors or windows when
cleaning the inside.
Never use fluids or solvents that are not designed
for cleaning your vehicle.
In operation, your vehicle is subjected to varying
external influences which, if gone unchecked, can
attack the paintwork as well as the underbody and
cause lasting damage.
Such damage is caused not only by extreme and varying
climatic conditions, but also by air polution, road salt,
tar, gravel and stone chipping. Grease and oil, fuel,
coolant, brake fluid, bird droppings, insects, tree resins
etc. should be removed immediately to avoid paint
damage. Frequent washing reduces and/or eliminates
the aggressiveness and potency of the above adverse
influences.

Practical hints

Car care

Technical
data

302
More frequent washings are necessary to deal with
unfavorable conditions; for example, near the ocean, in
industrial areas (smoke, exhaust emissions), or during
winter operation.
You should check your vehicle from time to time for
stone chipping or other damage. Any damage should be
repaired as soon as possible to prevent the start of
corrosion.
In doing so, do not neglect the underside of the vehicle.
A prerequisite for a thorough check is a washing of the
underbody followed by a thorough inspection. Damaged
areas need to be reundercoated.
Your vehicle has been treated at the factory with a waxbase rustproofing in the body cavities which will last for
the lifetime of the vehicle. Post-production treatment is
neither necessary nor recommended by Mercedes-Benz
because of the possibility of incompatibility between
materials used in the production process and others
applied later.
We have selected car-care products and compiled
recommendations which are specially matched to our
vehicles and which always reflect the latest technology.
You can obtain Mercedes-Benz approved car-care
products at your authorized Mercedes-Benz Center.

Index

Paintwork, painted body components

Scratches, corrosive deposits, corrosion or damage due
to negligent or incorrect care cannot always be removed
or repaired with the car-care products recommended
here. In such cases it is best to seek aid at your
authorized Mercedes-Benz Center.

Mercedes-Benz approved Paint Care should be applied
when water drops on the paint surface do not “bead up”,
normally in 3 to 5 months, depending on climate and
washing detergent used.

The following topics deal with the cleaning and care of
your vehicle and give important “how-to” information as
well as references to Mercedes-Benz approved car-care
products.

Mercedes-Benz approved Paint Cleaner should be
applied if paint surface shows signs of dirt embedding
(i.e. loss of gloss).
Do not apply any of these products or wax if your
vehicle is parked in the sun or if the hood is still hot.

Additional information can be found in the booklet titled
“Vehicle Care Guide”.

Use the appropriate MB-Touch-Up Stick for quick and
provisional repairs of minor paint damage (i.e. chips
from stones, vehicle doors etc.).

Power washer
When using a power washer for cleaning the vehicle
always observe manufacturer’s operating instructions.
Caution!
Never use a round nozzle to power wash tires. The
intense jet of water can result in damage to the tire.
Always replace a damaged tire.
Always keep the jet of water moving across the surface.
Do not aim directly at soft top, electrical parts, electrical
connectors, seals, or other rubber parts.

Engine cleaning

Vehicle washing

Prior to cleaning the engine compartment make sure to
protect electrical components and connectors from the
intrusion of water and cleaning agents.

Do not use hot water or wash your vehicle in direct
sunlight. Use only a mild car wash detergent, such as
Mercedes-Benz approved Car Shampoo.

Corrosion protection, such as MB Anticorrosion Wax
should be applied to the engine compartment after
every engine cleaning. Before applying, all control
linkage bushings and joints should be lubricated. The
poly-V-belt and all pulleys should be protected from any
wax.

Thoroughly spray the vehicle with a diffused jet of
water. Direct only a very weak spray towards the
ventilation intake. Use plenty of water and rinse the
sponge and chamois frequently.

Tar stains

In the winter, thoroughly remove all traces of road salt
as soon as possible.

Quickly remove tar stains before they dry and become
more difficult to remove. A tar remover is
recommended.

Rinse with clear water and thoroughly wipe dry with a
chamois. Do not allow cleaning agents to dry on the
finish.

When washing the underbody, do not forget to clean the
inner sides of the wheels.
Ornamental moldings
For regular cleaning and care of very dirty chromeplated parts, use a chrome cleaner.

Index

Headlamps, taillamps, turn signal lenses

Wiper blade

Use a mild car wash detergent, such as Mercedes-Benz
approved Car Shampoo, with plenty of water.

Clean the wiper blade rubber with a clean cloth and
detergent solution.

To prevent scratches, never apply strong force and use
only a soft, non-scratchy cloth when cleaning the lenses.
Do not attempt to wipe dirty lenses with a dry cloth or
sponge.

Note:
For safety reasons, remove electronic key from steering
lock before cleaning the wiper blade, otherwise the
wiper motor can suddenly turn on and cause injury.

Window cleaning
Light alloy wheels

Use a window cleaning solution on all glass surfaces. An
automotive glass cleaner is recommended.

Mercedes-Benz approved Wheel Care should be used for
regular cleaning of the light alloy wheels.

Note:

If possible, clean wheels once a week with MercedesBenz approved Wheel Care, using a soft bristle brush
and a strong spray of water.

For safety reasons, switch off wiper and remove
electronic key from steering lock before cleaning the
windshield, otherwise the wiper motor can suddenly
turn on and cause injury.

Follow instructions on container.
Note:

Plastic and rubber parts

Use only acid-free cleaning materials. The acid could
lead to corrosion.

Do not use oil or wax on these parts.

Upholstery

Hard plastic trim items

Using aftermarket seat covers or wearing clothing that
have the tendency to give off coloring (e.g. when wet
etc.) may cause the upholstery to become permanently
discolored. By lining the seats with a proper
intermediate cover, contact-discoloration will be
prevented.

Pour Mercedes-Benz approved Interior Care onto soft
lint-free cloth and apply with light pressure.
Plastic and rubber parts
Do not use oil or wax on these parts.

Leather Upholstery
Wipe leather upholstery with a damp cloth and dry
thoroughly or clean with Mercedes-Benz approved
Leather Care. Exercise particular care when cleaning
perforated leather as its underside should not become
wet.

Soft top

Notes:

Clean soft top with soft top raised and locked. Lower the
soft top into the storage compartment only if the soft top
is completely dry. If the soft top is kept in the storage
compartment for a lengthy period, raise it and air out
with the windows open about every 4 months.

When you run the vehicle through an automatic car
wash, never use hot-wax for conservation.

Dry cleaning:

Never use a power washer to clean the soft top, as you
may damage the soft top material.

Brush top (always from front to rear) with a soft-bristled
brush.
Wet cleaning:
Brush the dry top. Wash with a mild detergent and an
ample supply of lukewarm water by wiping with a softbristled brush or sponge from front to rear. Then rinse
thoroughly with clear water.
If only parts of the top have been washed, wet the entire
top and allow it to air-dry before lowering it into the
storage compartment.
Do not use sharp-edged instruments for the removal of
ice and snow.

Depending on the operation mode of the car wash, there
is the possibility of water drops entering the vehicle’s
interior.

Remove bird droppings immediately. The organic acid
damages the material and causes the soft top to leak.
In general, regular spraying or cleansing with clear
water is sufficient to keep the top clean.
Wash the top only when heavily soiled.
Light colored soft tops should be cleaned frequently to
prevent spots and dirt from setting in, which could stain
and discolor the soft top material permanently.
Caution!
Never use any gasoline, thinner, tar and stain removers,
glass cleaner, or similar organic solvents to clean the
soft top or wind screen. They will cause damage which
is not covered by the Mercedes-Benz Limited Warranty.

Engine oils

Air conditioner refrigerant

Engine oils are specifically tested for their suitability in
our engines. Therefore, use only engine oils
recommended by Mercedes-Benz. Information on
recommended brands is available at your authorized
Mercedes-Benz Center.

R-134a (HFC) refrigerant and special PAG lubricating oil
is used in the air conditioner system.
Never use R-12 (CFC) or mineral-based lubricating oil,
otherwise damage to the system will occur.

Please follow Service Booklet recommendations for
scheduled oil changes. Failure to do so could result in
engine damage not covered by the Mercedes-Benz
Limited Warranty.

Brake fluid
During vehicle operation, the boiling point of the brake
fluid is continuously reduced through the absorption of
moisture from the atmosphere. Under extremely hard
operating conditions, this moisture content can lead to
the formation of bubbles in the system thus reducing
the system’s efficiency.

Engine oil additives
Do not blend oil additives with engine oil. They may be
harmful to the engine operation.

The brake fluid must therefore be replaced every two
years, preferably in the spring.

Damage or malfunctions resulting from blending oil
additives are not covered by the Mercedes-Benz Limited
Warranty.

Fuel requirements

Caution!

Use only Premium unleaded meeting ASTM
standard D 439:

To maintain the engine’s durability and performance,
premium unleaded gasoline must be used. If premium
unleaded is not available and low octane fuel is used,
follow these precautions:
• have the fuel tank filled only partially with unleaded
regular and fill up with premium unleaded as soon
as possible,
• avoid full throttle driving and abrupt acceleration,
• do not exceed an engine speed of 3000 rpm, if the
vehicle is loaded with a light load such as two
persons and no luggage,
• do not exceed 2/3 of maximum accelerator pedal
position, if the vehicle is fully loaded or operating in
mountainous terrain.

The octane number (posted at the pump) must be
91 min. It is an average of both the Research (R) octane
number and the Motor (M) octane number: [(R+M)/2].
This is also known as ANTI-KNOCK INDEX.
Unleaded gasoline containing oxygenates such as
Ethanol, IPA, IBA and TBA can be used provided the
ratio of any one of these oxygenates to gasoline does not
exceed 10%, MTBE not to exceed 15%.
The ratio of Methanol to gasoline must not exceed 3%
plus additional cosolvents.
Using mixtures of Ethanol and Methanol is not allowed.
Gasohol, which contains 10% Ethanol and 90% unleaded
gasoline, can be used.
These blends must also meet all other fuel requirements
such as resistance to spark knock, boiling range, vapor
pressure etc..

Gasoline additives

Coolants

A major concern among engine manufacturers is carbon
build up caused by gasoline. Mercedes-Benz
recommends the use of only quality gasoline containing
additives that prevent the build up of carbon deposits.

The engine coolant is a mixture of water and
anticorrosion/antifreeze, which provides:
• corrosion protection,
• freeze protection,

After an extended period of using fuels without such
additives, carbon deposits can build up especially on the
intake valves and in the combustion area, leading to
engine performance problems such as:

• boiling protection (by increasing the boiling point).
The cooling system was filled at the factory with a
coolant providing freeze protection to approximately
-22°F (-30°C) and corrosion protection.

• warm-up hesitation,
• unstable idle,

If the antifreeze mixture is effective to -22°F (-30°C), the
boiling point of the coolant in the pressurized cooling
system is reached at approximately 266°F (130°C).

• knocking/pinging,
• misfire,

The coolant solution must be used year round to provide
the necessary corrosion protection and increase in the
boil-over protection. You should have it replaced every
3 years.

• power loss.
Do not blend other specific fuel additives with fuel.
They only result in unnecessary cost, and may be
harmful to the engine operation.

To provide the important corrosion protection, the
solution must be at least 45% anticorrosion/antifreeze
(equals a freeze protection to approx. - 22°F [-30°C]). If
you use a solution that is more than 55% anticorrosion/
antifreeze (freeze protection to approx. - 49°F [-45°C]),

Damage or malfunctions resulting from poor fuel
quality or from blending specific fuel additives are not
covered by the Mercedes-Benz Limited Warranty.

the engine temperature will increase due to the lower
heat transfer capability of the solution. Therefore, do not
use more than this amount of anticorrosion/antifreeze.
If the coolant level is low, water and MB anticorrosion/
antifreeze should be used to bring it up to the proper
level (have cooling system checked for signs of leakage).
The water in the cooling system must meet minimum
requirements, which are usually satisfied by normal
drinking water. If your are not sure about the water
quality, consult your authorized Mercedes-Benz Center.

Practical hints

Therefore the following product is strongly
recommended for use in your vehicle: Mercedes-Benz
Anticorrosion/antifreeze agent.

Technical
data

322
Before the start of the winter season (or once a year in
the hot southern regions), you should have the
anticorrosion/antifreeze concentration checked. The
coolant is also regularly checked each time you bring
your vehicle to your authorized Mercedes-Benz Center
for service.

Anticorrosion/antifreeze
Your vehicle contains a number of aluminum parts. The
use of aluminum components in motor vehicle engines
necessitates that anticorrosion/antifreeze coolant used
in such engines be specifically formulated to protect the
aluminum parts. (Failure to use such anticorrosion/
antifreeze coolant will result in a significantly
shortened service life.)

may depart significantly from the norm due to
variations in driving habits, service practices and
differences in road characteristics and climate.

This has been prepared as required of all manufactures
of passenger cars under Title 49, Code of U.S. Federal
Regulations, Part 575 pursuant to the “National Traffic
and Motor Vehicle Safety Act of 1966”.

Traction

Quality grades can be found where applicable on the
tire sidewall between tread shoulder and maximum
section width. For example:

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

Tread wear 200

Warning!

Uniform tire quality grading

Traction AA

Temperature A

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

All passenger vehicle tires must conform to federal
safety requirements in addition to these grades.
Treadwear
The treadwear grade is a comparative rating based on
the wear rate of the tire when tested under controlled
conditions on a specified government test course. For
example, a tire graded 150 would wear one and one-half
(1 1/2) times as well on the government course as a tire
graded 100. The relative performance of tires depends
upon the actual conditions of their use, however, and

Consumer information
Temperature
The temperature grades are A (the highest), B, and C,
representing 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,
and excessive temperature can lead to sudden tire
failure. The grade C corresponds to a level of
performance which all passenger vehicle tires must
meet under the Federal Motor Vehicle Safety Standard
No. 109. Grades B and A represent higher levels of
performance on the laboratory test wheel than the
minimum required by law.
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.
