46 Getting startedDrivingAfter a cold start, the automatic transmis-
sion shifts at a higher engine revolution.
This allows the catalytic converter to reach
its operating temperature earlier.
For more information on driving, see “Driv-
ing instructions” (
page 239).
Switching on headlamps
The exterior lamp switch is located on the
dashboard to the left of the steering wheel.Exterior lamp switch1Off

For more information on headlamps, see
“Lighting” (

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.!Place the gear selector lever in
positionR only when the vehicle is
stopped in order to avoid damaging the
transmission.!Do not run cold engine at high engine
speeds. Running a cold engine at high
engine speeds may shorten the service
life of the engine.
Warning!
G
Vehicles with automatic transmission:
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.

48 Getting startedDrivingSwitching on windshield wipers
Turn the combination switch to the
desired position depending on the
intensity of the rain.
0Windshield wipers off
IIntermittent wiping
IINormal wiper speed
IIIFast wiper speedSingle wipe

Press combination switch briefly in
direction 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 259).
iVehicles without rain sensor*:
Fast wiper speedIII goes to settingII
when the vehicle is standing still.
Vehicles with rain sensor*:
Intermittent wiping interval is depen-
dent on wetness of windshield. Wiping
will not occur with a front door open.
!Vehicles with 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 switch should not be left in inter-
mittent setting as the wipers will wipe
the windshield once every time the en-
gine is started. Dust that accumulates
on the windshield might scratch the
glass and/or damage the wiper blades
when wiping occurs on a dry wind-
shield.

Parking and locking
Switching off headlamps
Turn the exterior lamp switch
toM(
page 46).
For more information on headlamps, see
“Lighting” (
page 102).
Warning!
G
When leaving the vehicle, always remove the
SmartKey from the starter switch and lock
the vehicle. Do not leave children unattend-
ed in the vehicle, or with access to an un-
locked vehicle. Children could release the
parking brake and/or move the gear selec-
tor lever from positionP, either of which
could result in an accident and/or serious
injury.
Warning!
G
Getting out of your vehicle with the gear se-
lector lever not fully engaged in positionP is
dangerous. Also, when parked on an incline,
positionP alone may not prevent your vehi-
cle from moving, possibly hitting people or
objects.
Always set the parking brake in addition to
shifting to positionP (manual transmission:
first or reverse gear).
When parked on an incline, turn front wheel
towards the road curb.
