To cancel the cruise control, briefly push lever to
position 3.
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.
If the illuminated speedometer segments begin to
blink (e.g. when aquaplaning or when moving the
gear selector lever to position “N” while driving), the
cruise control is automatically switched off.
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.4Resume
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 selected speed is shown for approx. 5 seconds
in the multifunction display, and the corresponding
speedometer segments from the selected speed to
the vehicle maximum speed are illuminated.
The last memorized speed is canceled when the
electronic key in the starter switch is turned to
position 1 or 0.
Important!
Moving gear selector lever to position “N” switches the
cruise control off.

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.
The “CRUISE CONTROL - - -” message is displayed on
the multifunction display when any attempt is made to
store speeds below 25 mph (40 km/h) or when an
attempt is made to recall a speed when no speed has
been stored – the cruise control remains switched off.
See malfunction and warning messages on page 297 if
the cruise control has a malfunction.
Wa r n i n g !
Only use the cruise control if the traffic and
weather conditions make it advisable to travel at a
steady speed.• 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.
• 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.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.

(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 266.
The distance notification function can be activated
separately, see page 264.
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 265.
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.
Wa r n i n g !
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.Wa r n i n g !
Distronic requires familiarity with its operational
characteristics. We strongly recommend that you
review the following information carefully before
operating the system.

wheel spin and loss of control.
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.

Activation of Distronic
Any given speed above approximately 25 mph
(Canada: 30 km/h) can be maintained:
•Normally the vehicle is accelerated to the desired
speed with the accelerator.•Speed is set by briefly moving the control lever to
position 1 or 2.
The stored speed is displayed in the multifunction
display for approx. 5 seconds (see also page 266),
and one or two segments around the stored speed
light up on the speedometer dial (see also
page 267).
•Remove foot from the accelerator.
•When briefly lifting the control lever to position 1,
the vehicle speed will increase in increments of
5 mph (Canada: 10 km/h).
The stored speed is displayed in the multifunction
display for approx. 5 seconds (see also page 266),
and one or two segments around the stored speed
light up on the speedometer dial (see also

•When briefly lowering the control lever to
position 2, the vehicle speed will decrease in
increments of 5 mph (Canada: 10 km/h).
The stored speed is displayed in the multifunction
display for approx. 5 seconds (see also page 266),

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 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.Invalid attempts to activate
The multifunction display will show “–––” during
invalid attempts to activate Distronic:
•below a speed of approx. 25 mph
(Canada: 30 km/h),
•while the electronic stability program (ESP) is
switched off – ESP warning lampv in
speedometer dial is illuminated, see page 114,
•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 114,
•with the gear selector lever in position “P”, “R”
or “N” – check gear range indicator display in
instrument cluster, see page 114.
Wa r n i n g !
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.

Deactivation of Distronic
Briefly move the distronic control lever in “OFF”
direction (3) – the stored speed remains in the memory
until the electronic key in the starter switch is turned to
position 1 or 0.
Distronic is also deactivated if:
•the service brake pedal is depressed,
•the parking brake is activated,
•the vehicle decelerates to less than approximately
25 mph (Canada: 30 km/h), e.g. while maintaining
the distance to the vehicle ahead.•the gear selector lever is moved to position “N”,
•the electronic stability program (ESP) is active,
•the electronic stability program (ESP) is switched off
manually,
•Model CL 55 AMG only:
the vehicle speed exceeds approximately 160 mph
(260 km/h).
Note:
A signal sounds and the message “DTR OFF” appears
for 5 seconds in the multifunction display everytime
Distronic is deactivated.
Wa r n i n g !
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.
