Warning! G
It is dangerous to shift the gear selector
lever out of park position P or neutral
position N 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 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.
!
Allow engine to warm up under low load use.
Do not place full load on the engine until the
operating temperature has been reached
(
page 311).
Shift into park position P or reverse gear R only
when the vehicle is stopped.
Avoid spinning of a drive wheel for an extended
period when driving off on slippery road
surfaces. This may cause serious damage to the
drivetrain which is not covered by the
Mercedes-Benz Limited Warranty.
