42 Getting startedDrivingProper use of seat belts
Do not twist the belt when fastening.
Adjust seat belt so that the shoulder 
portion is located as close as possible 
to the middle of the shoulder (it should 
not touch the neck or pass under the 
arm).
Position the lap belt as low as possible 
on your hips (over hip joint) and not 
across the abdomen.
Place the seat backrest in a nearly up-
right position.
Never use a seat belt for more than one 
person at a time.
Do not fasten a seat belt around a per-
son and another object at the same 
time.
Check your seat belt during travel to 
ensure that it is properly positioned.
Ensure that the seat belt is always fit-
ted snugly. You should avoid wearing 
bulky clothing, such as winter coats, 
when traveling in the vehicle.
Starting the engine
Warning!
G
Do not pass belts over sharp edges. They 
could tear.
Do not allow the belt to get caught in the 
door or in the seat adjustment mechanism. 
This could damage the belt.
Never attempt to make modifications to 
seat belts. This could impair the effective-
ness of the belts.
Damaged seat belts or belts that were highly 
stressed in an accident must be replaced by 
an authorized Mercedes-Benz Center.
Warning!
G
Inhalation of exhaust gas is hazardous to 
your health. All exhaust gas contains carbon 
monoxide, and inhaling it can cause uncon-
sciousness and lead to death.
Do not run the engine in confined areas 
(such as a garage) which are not properly 
ventilated. If you think that exhaust gas 
fumes are entering the vehicle while driving, 
have the cause determined and corrected 
immediately. If you must drive under these 
conditions, drive with at least one window 
fully open.

tion of the KEYLESS-GO card.
or:
Start the engine with the SmartKey as 
radio signals from another source may 
be interfering with the KEYLESS-GO 
card.
Repeat the starting procedure 
(page 42). Remember that extended 
starting attempts can drain the battery.
Get a jump start (
page 347).If the engine does not start after several

Firmly depress the brake pedal.
Move selector lever to positionDorR.
Release the brake pedal.
Carefully depress the accelerator 
pedal.
Once the vehicle is in motion, the automat-
ic central locking system engages and the 
locking knobs drop down.After a cold start the automatic transmis-
sion engages at a higher revolution. This al-
lows the catalytic converter to reach its 
operating temperature earlier.iYou can open a locked door from the 
inside. Open door only when conditions 
are safe to do so.!If you hear a warning signal when driv-
ing off, you have forgotten to release 
the parking brake.
Release the parking brake.
iWait for the gear selection process to 
complete before setting the vehicle in 
motion.Warning!
G
It is dangerous to shift the selector lever out 
ofPorN if the engine speed is higher than 
idle speed. If your foot is not firmly on the 
brake pedal, the vehicle could accelerate 
quickly forward or in reverse. You could lose 
control of the vehicle and hit someone or 
something. Only shift into gear when the en-
gine is idling normally and when your right 
foot is firmly on the brake pedal.
!Simultaneously depressing the acceler-
ator pedal and applying the brake re-
duces engine performance and causes 
premature brake and drivetrain wear.Warning!
G
On slippery road surfaces, never downshift 
in order to obtain braking action. This could 
result in drive wheel slip and reduced vehi-
cle control. Your vehicle’s ABS will not pre-
vent this type of loss of control.

Problems while driving
The engine runs erratically and misfires
An ignition cable may be damaged.

erating properly.
Unburned gasoline may have entered 
the catalytic converter and damaged it.
Give very little gas.
Have the problem repaired by an au-
thorized Mercedes-Benz Center as 
soon as possible.The coolant temperature is over 248°F 
(120°C)
The coolant is too hot and is no longer 
cooling the engine.
Stop the vehicle as soon as possible 
and turn off the engine. Allow engine 
and coolant to cool.
Check the coolant level and add cool-
ant if necessary (
page 268).

shield wipers, switch off the wipers.
For safety reasons, withdraw 
SmartKey from starter switch. Re-
move blockage.
Turn the windshield wipers on
