46 Getting startedDrivingAfter a cold start the transmission engages
at a higher revolution. This allows the cata-
lytic converter to reach its operating tem-
perature earlier.More information can be found in the “Op-
eration” section (
page 177).
For information on off-road driving, see
Driving instructions (page 186).

!If you hear a warning signal when driv-
ing off, you have forgotten to release
the parking brake.
Release the parking brake.Warning!
G
It is dangerous to shift the 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 en-
gine is idling normally and when your right
foot is firmly on the brake pedal.
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.
