2008 MERCEDES-BENZ G55AMG door lock

56 Getting started
Driving
After a cold start, the transmission 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 245).
For information on off-road driving, see
“Off-road driving” (
page 253).
Switching on headlamps
Low beam headlamps
The exterior lamp switch is located on the
dashboard to the left of the steering wheel.
Exterior lamp switch
1 Off
2 Low beam headlamps on
Turn the exterior lamp switch to
position B.
The low beam headlamp indicator
lamp B in the instrument cluster
comes on (
page 26).
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 155).
You can open a locked door from the inside.
Open door only when conditions are safe to do
so.
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 of P or N if the engine speed is
higher than idle speed. If your foot is not
firmly on the brake pedal, the vehicle could
accelerate quickl y 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.
!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.

special seat belt retractors for secure fas-
tening of child restraints.
To fasten a child restraint, follow child
restraint instructions for mounting. Then
pull the shoulder belt out completely and
