Speedometer (9)
When the cruise control is activated, the segments on
the speedometer scale between the set speed to the top
of the scale are illuminated. Cruise control, see
page 253.
When the Distronic (DTR) is activated, one or two
segments around the speed stored in memory light up
in the speedometer dial. Distronic (DTR), see page 256.Note:
The speed display is set to read out for
•USA in mph
•Canada in km/h.

cluster displayPractical hints Car care Index Cruise control
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.
1Accelerate and set:
Lift lever briefly to set speed. Hold lever up to
accelerate.2Decelerate 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.
Speed is set by briefly pushing the lever to
position 1 or 2. The accelerator can then be
released.
The selected speed is shown for approximately
5 seconds in the multifunction display, and the
corresponding speedometer segments from the
selected speed to the vehicle maximum speed are
illuminated.
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
slig htly, e. g . to a da pt to th e tra f f ic f low, h old 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.

3Canceling
To cancel the cruise control, briefly push lever to
position 3.
When you step on the brake pedal or the vehicle
speed drops below approximately 25 mph (40 km /
h), for example when driving upgrade, the cruise
control will be canceled.
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 approximately 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 approximately
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.

The speed stored in memory is displayed in the
multifunction display, and one or two segments around
the stored speed light up in the speedometer dial, see
page 270.
1Accelerate and set:
To increase the speed by 5 mph (Canada: 10 km/h) –
brief ly lift lever up.
2Decelerate and set:
To reduce the speed by 5 mph (Canada: 10 km/h) –
briefly depress lever.3Canceling
To cancel Distronic, briefly push lever to position 3.
The last set speed remains stored in memory.
4Resume
•If the lever is briefly pulled to position 4 when
driving at a speed above approximately 25 mph
(Canada: 30 km/h), the vehicle resumes the
speed which was selected prior to the
cancellation of Distronic.
•For minor increases of speeds in increments of
1 mph (Canada: 1 km/h) – briefly pull lever to
position 4.
The last memorized speed is canceled when the
electronic key in the starter switch is turned to
position 1 or 0.

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

stored speed light up on the speedometer dial (see

•Remove foot from the accelerator.
•When briefly lifting the control lever to position 1,
the vehicle speed will increase in increments of

•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 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 approximately 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.

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.

Driving with Distronic activated
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 268. Segments in the
speedometer illuminate to indicate the speed range from the speed of the vehicle in front up to your
vehicle’s selected speed. See also page 269 for notes on
the multifunction displays.
