Do not pass belts over sharp edges. They
could tear.
Do not allow the belt to get caught in the
door or in the seat adjustment mechanism.
This could damage the belt.
Never attempt to make modifications to
seat belts. This could impair the effective-
ness of the belts.

severely weaken them. In a crash, they may
not be able to provide adequate protection.
Damaged seat belts or belts that were highly
stressed in an accident must be replaced.

G
Inhalation of exhaust gas is hazardous to
your health. All exhaust gas contains carbon
monoxide, and inhaling it can cause uncon-
sciousness and possible 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 only with at least one win-
dow fully open.

2Release button
Pull up slightly on parking brake
lever1 and press release button2.

Push parking brake lever1 down to
its original position.
The brake warning lamp; (USA

DrivingWarning!
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.!If you hear a warning signal and the
message
Release parking brake
ap-
pears in the multifunction display when
driving off, you have forgotten to re-
lease the parking brake.
!Simultaneously depressing the acceler-
ator pedal and the brake pedal reduces
engine performance and causes pre-
mature brake and drivetrain wear.iOnce the vehicle is in motion, the auto-
matic central locking system engages
and the locking knobs drop down.
For more information, see “Automatic
central locking” (
page 101).

54 Getting startedDrivingManual transmission

complete before setting the vehicle in
motion.iDuring the brief warm-up, transmission
upshifting is delayed. This allows the
catalytic converter to heat up more
quickly to operating temperature.
Warning!
G
Vehicles with automatic transmission*: It is
dangerous to shift the gear selector lever
out of
PorN if the engine speed is higher
than idle speed. If your foot is not firmly on
the brake pedal, the vehicle could acceler-
ate quickly forward or in reverse. You could

or something. Only shift into gear when the
engine is idling normally and when your right
foot is firmly on the brake pedal.
