Warning!G
When leaving the vehicle, always remove the
SmartKey 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
personal injury.
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.
!If you hear a warning signal and the
message
Release parking brake appears in
the multifunction display when driving off, you
have forgotten to release the parking brake.
Release the parking brake (
page 53).
!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.
!Simultaneously depressing the accelerator
pedal and applying the brakes reduces engine
performance and causes premature brake and
drivetrain wear.

54 Getting started
Driving
Manual transmission
Depress the brake pedal.
Fully depress the clutch pedal.
Move gearshift lever to first gear to
drive forward, or to reverse gear to
drive rearward.
Simultaneously release the brake pedal
and slowly the clutch pedal.
Carefully depress the accelerator
pedal.Automatic transmission*
Depress the brake pedal.
Move the gear selector lever to
positionDorR.
Release the brake pedal.
Carefully depress the accelerator

After a cold start, the transmission engag-
es at a higher revolution. This allows the
catalytic converter to reach its operating
temperature earlier.
iOnce the vehicle is in motion, the automatic
central locking system engages and the locking
knobs drop down.
The automatic door lock feature can be deacti-
vated (
page 146).
You can open a locked door from the inside.
Open door only when conditions are safe to do
so.
Warning!G
It is dangerous to shift the gear selector
lever out ofPorN 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 engine is idling normally and when
your right foot is firmly on the brake pedal.
!In order to avoid damage to the transmis-
sion:

Wait for the gear selection process to com-
plete before setting the vehicle in motion.

Place the gear selector lever in
positionDorR only when the vehicle is
stopped.

effort is necessary to brake and steer the ve-
hicle.
Warning!G
Do not park this vehicle in areas where
combustible materials such as grass, hay or
leaves can come into contact with the hot
exhaust system, as these materials could be
ignited and cause a vehicle fire.
To reduce the risk of personal injury or
damage to the vehicle drivetrain as a result
of vehicle movement, before turning off the
engine and leaving the vehicle always:

Keep right foot on brake pedal.

Pull the parking brake lever up as many
notches as possible.

is in motion can cause the rear wheels to
lock up. You could lose control of the vehicle
and cause an accident. In addition, the
vehicle’s brake lights do not light up when
the parking brake is engaged.
