seat belts. This could impair the effective-
ness of the belts.

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.

When leaving the vehicle always remove the
key from the starter switch, take the KEY-
LESS-GO card (if so equipped) with you and
lock the vehicle. Do not leave children unat-
tended in the vehicle, or with access to an
unlocked vehicle. Children could release the
parking brake, which could result in an acci-
dent and/or serious injury.

42 Getting startedDrivingDriving
Place the gear selector lever in
positionD orR.

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 transmission engag-
es at a higher revolution. This allows 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
ofP orN 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.

Getting out of your vehicle with the selector
lever not fully engaged in positionP is dan-
gerous. Also, when parked on an incline,
positionP alone may not prevent your vehi-

When parked on an incline, also turn front
wheel against road curb.
iAlways set the parking brake in addi-
tion to shifting to positionP.
