Starting and turning off the engine
Before starting
Ensure that parking brake is engaged and that selector 
lever is in position “P” or “N” (gearshift lever in 
neutral). Turn electronic key in starter switch to 
position 2.
Starting
Vehicles with automatic transmission:
Do not depress accelerator. Briefly turn electronic key in 
starter switch clockwise to the stop and release. The 
starter will engage until the engine is running.
If engine will not run, and the starting procedure stops, 
turn electronic key completely to the left and repeat 
starting the engine.
After several unsuccessful attempts, have the system 
checked at the nearest authorized Mercedes-Benz 
Center. Vehicles with manual transmission:
Do not depress accelerator. Fully depress clutch pedal, 
otherwise the engine cannot be started due to the 
integrated safety interlock.
Turn electronic key in starter switch clockwise to the 
stop. Release only when the engine is firing regularly.

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” or in case of manual 
transmission declutch. 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.

and death.To assure sufficient fresh air ventilation, open a 
window slightly on the side of the vehicle not 
facing the wind.

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 
following will assist in maintaining the set cruise 
controlled speed: Vehicles with automatic transmission:
Downshift occurs (max. to 3rd gear) to maintain the set 
cruise controlled 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.
Vehicles with manual transmission:
The set cruise controlled speed is switched off when 
declutching exceeds four seconds during downshifting a 
gear.
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.
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.
