51 Getting started
Driving
Release the brake pedal.
Carefully depress the accelerator.Once the vehicle is in motion, the
automatic 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 faster.
For more information, see “Driving instruc-
tions” (
page 259).
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 damaging 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 only when the vehicle is
stopped.
!If you hear a warning signal and a mes-
sage in the multifunction display ap-
pears when driving off, you have
forgotten to release the parking brake.
Release the parking brake.!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.iYou can open a locked door from the
inside. Open doors only when condi-
tions are safe to do so.
You can deactivate the automatic lock-
ing using the control system
(page 162).
