Distronic (DTR)
(optional)
When activated the Distronic system increases driving
convenience, for example over long distances, as it
automatically maintains a speed set by the driver by
actively regulating the throttle setting. It also maintains
within certain limitations a preset distance to a vehicle
ahead.
With Distronic switched off, the multifunction display
continues to show the distance to the vehicle ahead, if
so selected, see page 274.
The distance warning function can be activated
separately, see page 271.
In Distronic mode, if the distance sensor detects a
slower moving vehicle directly ahead, your vehicle
speed will be reduced to the extent permitted by
reduced throttle and up to 20% of vehicle braking power,
so that you follow that vehicle at a preset distance, see
page 272.
Maximum range of detection is approximately 500 ft.
(150 m).

Any given speed between 25 mph (Canada: 30 km/h)
and 110 mph (Canada: 180 km/h) can be maintained
with the Distronic by operating the control lever on the
steering column.
Warning!
Distronic is a convenience system, its speed
adjustment reduction capability is intended to
make cruise control more effective and usable
when traffic speeds vary. It is not, however,
intended to nor does it replace the need for extreme
care. The responsibility for the vehicle speed and
the distance to the vehicle ahead, including most
importantly brake operation to assure safe stopping
distance, rests always with the driver.
Warning!
Distronic requires familiarity with its operational
characteristics. We strongly recommend that you
review the following information carefully before
operating the system.

Note:
Warning!
For operation in the USA only: This device complies
with Part 15 of the FCC Rules. Operation is subject to
the following two conditions:
Only use Distronic if the traffic and weather
conditions make it advisable to travel at a steady
speed.
(1) This device may not cause harmful interference, and
Use of Distronic can be dangerous on winding
roads or in heavy traffic because conditions do not
allow safe driving at a steady speed.
(2) this device must accept any interference received,
including interference that may cause undesired
operation.
Use of Distronic can be dangerous on slippery
roads. Rapid changes in tire adhesion can result in
wheel spin and loss of control.
Any unauthorized modification to this device could void
the user’s authority to operate the equipment.
Distronic does not act upon adverse sight distance
conditions. Do not use Distronic during conditions
of fog and heavy rain, snow or sleet.
The “Resume” function should only be operated if
the driver is fully aware of the previously set speed
and wishes to resume this particular preset speed.
Distronic does not recognize accordingly and will
not react to stationary objects. It is designed and
intended only to maintain a set speed and keep a
set distance from moving objects in front of it.

• For a more precise setting the speed can be
increased in increments of 1 mph (Canada: 1 km/h)
by briefly pulling the control lever in direction (4).
Caution!
If the driver’s foot is not fully removed from the
accelerator pedal, the message “DISTRONIC OVERRIDE”
appears in the multifunction display. The Distronic
control system will be overridden and it will not
regulate the preset vehicle speed and following
distance. The vehicle speed and following distance will
be determined only by the accelerator pedal position.
Warning!
Distronic brakes (up to 20% of vehicle braking
power) the vehicle to restore the preset distance or
to maintain the speed. The brake pedal is
automatically retracted as this happens.
Keep driver’s foot area clear at all times, including
the area under the brake pedal. Objects stored in
this area may impair pedal movement which could
interfere with the braking ability of the Distronic
system.
Do not place your foot under the brake pedal – your
foot could become caught.

• while the electronic stability program (ESP) is
switched off – ESP warning lamp v in
speedometer dial is illuminated, see page 112,
• by moving the distronic control lever in “RESUME”
direction (4) when no speed is stored in memory,
• during the initialization and self-test phase after the
engine is started – this can take up to 2 minutes,
• while depressing the service brake pedal,
• while the parking brake is set – check ; warning
lamp (Canada: !) in instrument cluster, see
page 112,
• with the gear selector lever in position “P”, “R”

• the electronic stability program (ESP) is active,
• the electronic stability program (ESP) is switched off
manually.
Distronic is also deactivated if:
Note:
• the service brake pedal is depressed,
A signal sounds and the message “DISTRONIC OFF”
appears for 5 seconds in the multifunction display
everytime Distronic is deactivated (except when moving
distronic control lever in “OFF” direction).
• the parking brake is activated,
• the vehicle decelerates to less than approximately
25 mph (Canada: 30 km/h), e.g. while maintaining

Warning!
The Distronic switches off and releases the brakes
when the vehicle decelerates below the minimum
speed of 25 mph (Canada: 30 km/h) by operation of
the system. At that time, the driver must apply the
brakes in order to reduce vehicle speed further or
bring it to a stop.

from the speed of the vehicle in front up to your
vehicle’s selected speed. See also page 274 for notes on
the multifunction displays.
Warning!
Distronic brakes (up to 20% of vehicle braking
power) the vehicle to restore the preset distance or
to maintain the speed. The brake pedal is
automatically retracted as this happens.
Keep driver’s foot area clear at all times, including
the area under the brake pedal. Objects stored in
this area may impair pedal movement which could
interfere with the braking ability of the Distronic
system.
With the electronic key in starter switch position 2, the
distance warning lamp l in the speedometer dial
comes on and goes out with the engine running.
If the distance sensor detects a slower vehicle moving in
front, your vehicle speed will be reduced by
deceleration and braking of up to 20% of the vehicle
braking capacity, so that you follow the vehicle ahead at
the preset distance, see page 272. Segments in the
speedometer illuminate to indicate the speed range
Do not place your foot under the brake pedal – your
foot could become caught.

part3_01.fm Seite 267 Montag, 7. Mai 2001 7:05 07
Warning!
Caution!
An intermittent warning sounds and the distance
warning lamp in the speedometer dial is
illuminated if the Distronic system calculates that
the distance to the vehicle ahead and your vehicle’s
current speed indicate that Distronic will not be
capable of slowing the vehicle sufficiently to
maintain the preset following distance, which
creates a danger of a collision.
If the driver’s foot is not fully removed from the
accelerator pedal, the message “DISTRONIC OVERRIDE”
appears in the multifunction display. The Distronic
control system will be overridden and it will not
regulate the preset vehicle speed and following
distance. The vehicle speed and following distance is
determined only by the accelerator pedal position.
Distronic works on steep uphill and downhill gradients
by downshifting gears and applying the brakes to
maintain the speed selected by the driver. The
transmission will upshift again once the gradient evens
out.
Immediately brake the vehicle to increase the
distance to the vehicle in front of you. The warning
sound is intended as a final caution that you have
not interceded with your own braking inputs to
avoid a potentially dangerous situation. Do not wait
for the operation of the warning signal to intercede
with your own braking as that will result in
potentially dangerous emergency braking which
will not always result an impact being avoided.
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.
Distronic is deactivated if a vehicle in front causes your
vehicle to slow down to less than approximately 25 mph
(Canada: 30 km/h). A signal sounds and the message
“DISTRONIC OFF” appears for 5 seconds in the
multifunction display.
Tailgating increases the risk of an accident.
The distance warning sound continues until the driver
activates the brake pedal, or the preset distance is
obtained. As soon as the preset distance is obtained, the
distance warning lamp goes out.

Warning!
Distronic works to maintain the speed selected by
the driver unless a moving obstacle proceeding
directly ahead of it in the same travel direction is
detected (e.g. following another vehicle ahead at a
distance set by Distronic). This means that:
• your vehicle can pass another vehicle after you
change lanes,
• while in a sharp turn or if the vehicle in front
is in a sharp turn, Distronic could lose sight of
a vehicle traveling in front of it, then your
vehicle could accelerate to the previously
selected speed.
Distronic regulates only the distance between your
vehicle and those directly ahead, but does not
register stationary objects in the roadway, e.g.:

The driver must always be on the alert and observe
all traffic and intercede with steering and braking
inputs as necessary.
Important!
When starting the engine, Distronic goes through an
initialization and self-test phase – this can take up to
2 minutes.
The most likely cause for a malfunctioning system is
caused by a dirty sensor (located behind the hood
grille), especially at times of snow and ice or heavy rain.
In such a case, Distronic will switch off, and the
message “DISTRONIC – CLEAN SENSOR!” appears in
the multifunction display.
Warning!
Distronic should not be used in snowy or icy road
conditions.
• a stopped vehicle in a traffic jam,
• a disabled vehicle,
• an oncoming vehicle.
For cleaning and care of the Distronic sensor, see
page 385.
Restart the engine after cleaning the sensor.
The following are some sample situations which may
influence the functions of Distronic.
Index
part3_01.fm Seite 269 Montag, 7. Mai 2001 7:05 07
The Distronic system’s detection zone is relatively
narrow at the start and becomes broader as it senses
further from the vehicle. Thus, Distronic may not
recognize another vehicle coming into your path close
to the front of your vehicle. You must be prepared to
intercede with braking or steering as necessary.
A vehicle not traveling directly in front of you could
cause detection problems, the actual distance to that
vehicle really being much shorter.
Traveling through turns or bends in the roadway may
result in Distronic detecting a moving vehicle traveling
in front but not in your lane of travel, causing your
vehicle to brake late or unexpectedly. You must be
prepared to intercede with accelerator or brake
application as necessary.

Distance warning function
Important!
Even if Distronic is deactivated, the distance to the
vehicle ahead continues to be measured, see page 274
for multifunction display.
With the Distronic switched off, only the distance
warning function operates, meaning the vehicle does
not slow down.
The Distronic lamp in the speedometer dial illuminates
to advise the driver of a situation which under normal
braking conditions and dry surfaces should have been
addressed by the driver.
Distronic does not register oncoming vehicles. Therefore
there is no distance warning.
The distance warning function can be activated
separately, see page 271. It operates when driving at
speeds above approximately 25 mph
(Canada: 30 km/h).
If the distance warning lamp in the speedometer
dial lights up while driving and an intermittent
warning sounds, immediate attention on the part of
the driver is required.
When recognizing a stationary obstacle or a slower
vehicle moving in the vehicle’s path and the danger of a
collision exists, the distance warning lamp in the
speedometer dial lights up and simultaneously an
intermittent warning sounds.
As required by the traffic situation, apply the
service brakes and navigate around a possible
obstacle. However, do not drive by relying on the
distance warning function as that will result in an
emergency braking application which, especially
depending on road surface conditions and driver
reaction, will not always be able to avoid a collision.
Warning!
When pressing the brake pedal, the warning sound
stops. The warning sound also stops, when the distance
to the vehicle ahead is sufficient again without applying
the brake pedal. In this case the distance warning lamp
also extinguishes
