it can no longer be turned in the switch. In
this case, the steering is locked.
To unlock remove SmartKey from the
starter switch and reinsert.
If the engine does not start as described,
carry out the following steps:
If you are starting the engine with the
SmartKey, turn SmartKey in starter
switch to position0 and repeat starting
procedure.
If you are starting the engine with
KEYLESS-GO: Close any doors that
may be open to allow for better detec-
tion of the SmartKey with
KEYLESS-GO.
Or:
Start the engine with the SmartKey as
radio signals from another source may
be interfering with the SmartKey with
KEYLESS-GO.
Repeat the starting procedure
(page 52). Remember that extended
starting attempts can drain the battery.
Get a jump start (
page 464).
If the engine does not start after several
starting attempts, there could be a mal-
function in the engine electronics or in the
fuel supply system.
Notify an authorized Mercedes-Benz
Center.
56 Getting startedDrivingAfter a cold start, the automatic transmis-
sion shifts at a higher engine revolution.
This allows the catalytic converter
(gasoline engine) or the oxidation catalyst
(diesel engine) to reach its operating tem-
perature earlier.
For more information on driving, see “Driv-
ing instructions” (
page 309).
Switching on headlamps
Low beam headlamps
The exterior lamp switch is located on the
dashboard to the left of the steering wheel.Exterior lamp switch1Off
2Low beam headlamps on
Turn the exterior lamp switch to
positionB.
The low beam headlamps and the low
beam headlamp indicator lampB in
the instrument cluster come on
(page 26).
!
If you hear a warning signal and the mes-
sage Release parking brake
appears in the
multifunction display when driving off, you have
forgotten to release the parking brake.
Release the parking brake (
page 62).
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.
Warning!
G
It is dangerous to shift the gear selector le-
ver out ofP orN if the engine speed is high-
er than idle speed. If your foot is not firmly
on the brake pedal, the vehicle could accel-
erate quickly forward or in reverse. You
could lose control of the vehicle and hit
someone or something. Only shift into gear
when the engine is idling normally and when
your right foot is firmly on the brake pedal.!
Simultaneously depressing the accelerator
pedal and applying the brakes reduces engine
performance and causes premature brake and
drivetrain wear.

Do not operate the windshield wipers when
the windshield is dry. Dust that accumulates on
a windshield might scratch the glass and/or
damage the wiper blades when wiping occurs on
a dry windshield. If it is necessary to operate the
windshield wipers in dry weather conditions, al-
ways operate the windshield wipers with wind-
shield washer fluid (
page 59).
!
If anything blocks the windshield wipers
(leaves, snow, etc.), switch them off immediate-
ly.
For safety reasons, stop the vehicle in a safe
location and
remove SmartKey from starter switch
or
turn off the engine by pressing the
KEYLESS-GO* start/stop button and
open the driver’s door (with the driver’s
door open, starter switch is in
position0, same as with SmartKey re-
moved from starter switch)
before attempting to remove any blockage.
Remove blockage.
Turn the windshield wipers on again.If windshield wipers fail to function at all in com-
bination switch positionU or V,
set the combination switch to the next high-
er wiper speed
have the windshield wipers checked at the
nearest authorized Mercedes-Benz Center.
i
When the windshield wipers are switched on
and you brake the vehicle to a stop, the time in-
terval between wiper operations is increased.
60 Getting startedDrivingProblems while driving
The engine runs erratically and misfires
An ignition cable may be damaged
(gasoline engine only).
The engine electronics may not be op-
erating properly.
Unburned gasoline may have entered
the catalytic converter and damaged it
