Do not adjust the driver’s seat while driving.
Adjusting the seat while driving could cause
the driver to lose control of the vehicle.
Never place hands under the seat or near
any moving parts while a seat is being ad-
justed.
Never ride in a moving vehicle with the seat
back in an excessively reclined position as
this can be dangerous. You could slide un-
der the seat belt in a collision. If you slide
under it, the belt would apply force at the ab-
domen or neck.
That could cause serious or fatal injuries.
The seat back and seat belts provide the
best restraint when the wearer is in a nearly
upright position and belts are properly posi-
tioned on the body. Your seat must be ad-
justed so that you can correctly fasten your
seat belt (
page 45).
Warning!

When leaving the vehicle, always remove the
SmartKey from the starter switch, take it
with you, and lock the vehicle.
Even with the SmartKey removed from the
starter switch or the vehicle, the seats can
be operated. Therefore, do not leave chil-
dren unattended in the vehicle, or with ac-
cess to an unlocked vehicle. Unsupervised
use of vehicle equipment may cause an ac-
cident and/or serious personal injury.

tilated. If you think that exhaust gas fumes
are entering the vehicle while driving, have
the cause determined and corrected imme-
diately. If you must drive under these condi-
tions, drive only with at least one window
fully open.

Pull lever2 upwards slightly, press re-
lease knob1 and move the lever
down to the stop.
The warning lamp; (USA only)
or3 (Canada only) in the
instrument cluster goes out.
Driving
Depress the brake pedal.
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.
After a cold start, the transmission engag-
es at a higher revolution. This allows the
catalytic converter to reach its operating
temperature earlier.
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.
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.!In order to avoid damage to the trans-
mission:
Wait for the gear selection process
to complete before setting the vehi-
cle in motion.
Place the gear selector lever in
positionR or P only when the vehi-
cle is stopped.
!If you hear a warning signal when driv-
ing off, you have forgotten to release
the parking brake.
Release the parking brake.!Do not run cold engine at high engine
speed. Running a cold engine at high
engine speed may shorten the service
life of the engine.
