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.
Chains should only be used on the rear wheels. Follow
the manufacturer’s mounting instructions.
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 221.
Use of snow chains is only permissible when winter
tires are mounted, see technical data on page 303.
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 t he veh icle is pa rked af te r b eing driven on sal t trea ted
road s, th e braking ef f ic iency should be tested as soon a s
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 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.

To cancel the cruise control, brief ly 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 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 last memorized speed is canceled when
the electronic key in the steering lock is turned to
position 1 or 0.Important!
Moving gear selector lever to position “N” switches the
cruise control off.
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.

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.Neverth eless, in some ca ses you m ay have to step on t he
bra ke peda l to slow d own. In t his ca se th e cruise control
is switched off.
Use the lever to resume the previously set speed.
