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.

(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 only with at least one win-
dow fully open.

handle2.
The warning lamp ; (USA only) or
3 (Canada only) in the instrument
cluster goes out.Driving

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 (gasoline
engine) or the oxidation catalyst (Diesel
engine) to reach its operating temperature
earlier.
Warning!
G
When leaving the vehicle, always remove the
SmartKey or the SmartKey with
KEYLESS-GO* from the starter switch, take
it with you and lock the vehicle. Do not leave
children unattended in the vehicle, or with
access to an unlocked vehicle. Children
could release the parking brake, which
could result in an accident and/or serious
injury.
iWait for the gear selection process to
complete before setting the vehicle in
motion.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 and a mes-
sage appears in the multifunction dis-
play when driving off, you have
forgotten to release the parking brake.
Release the parking brake.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 acceler-
ator pedal and applying the brake re-
duces engine performance and causes
premature brake and drivetrain wear.

52 Getting startedDrivingSwitching on windshield wipers
Turn the combination switch to the de-
sired position depending on the inten-
sity of the rain.
0Windshield wipers off
IIntermittent wiping (interval depen-
dent on wetness of windshield)
IINormal wiper speed
IIIFast wiper speedIntermittent wiping

Turn the combination switch to
positionI.
Single wipe

Press combination switch briefly in di-
rection of arrow1.
The windshield wipers wipe one time
without washer fluid.
Wiping with windshield washer fluid

Push combination switch in direction of
arrow1 past the resistance point.
The windshield wipers operate with
washer fluid.
For information on filling up the washer
reservoir, see “Windshield washer system
and headlamp cleaning system*”
(
page 310).
iIntermittent wiping interval is depen-
dent on wetness of windshield. After
the initial wipe, pauses between wipes
are automatically controlled by the rain
sensor.
!Do not leave windshield wipers in inter-
mittent setting when the vehicle is tak-
en to an automatic car wash or during
windshield cleaning. Wipers will oper-
ate in the presence of water sprayed on
the windshield, and wipers may be
damaged as a result.
The combination switch should not be
left in intermittent setting as the wipers
will wipe the windshield once every
time the engine is started. Dust that ac-
cumulates on the windshield might
scratch the glass and / or damage the
wiper blades when wiping occurs on a
dry windshield.
iIntermittent wiping is interrupted when
the vehicle is at a standstill and a front
door is opened.
