When leaving the vehicle, always remove the
SmartKey or SmartKey with KEYLESS-GO*
from the starter switch, take it 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.
iWait for the gear selection process to
complete before setting the vehicle in
motion.iShifting from gear positionP to posi-
tion R, N, orD is only possible with the
brake pedal depressed. Without the
brake pedal depressed, the gear selec-
tor lever can be moved, but the parking
pawl remains engaged, not allowing
shifting to occur.

57 Getting started
Driving

Carefully depress the accelerator
pedal.
Once the vehicle is in motion, the auto-
matic central locking system engages
and the locking knobs drop down.After 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, see “Driving instruc-
tions” (
page 331).
iThe automatic door lock feature can be
deactivated (
page 188).
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 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.
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.Warning!
G
It is dangerous to shift the gear 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 engine is idling normally and when
your right foot is firmly on the brake pedal.
!Shift the automatic transmission to
positionP orR 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.!Simultaneously depressing the acceler-
ator pedal and applying the brake re-
duces engine performance and causes
premature brake and drivetrain wear.
