Winter driving instructions
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.
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.
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.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.
Wa r n i n g !
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.To assure sufficient fresh air ventilation, open a
window slightly on the side of the vehicle not
facing the wind.

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 approx. 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
slightly, e.g. to adapt to the traffic f low, 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.

cluster displayPractical hints Car care Index 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 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.
