54 Getting startedDrivingAfter a cold start, the automatic transmis-
sion engages at a higher revolution. This al-
lows the catalytic converter (gasoline
engine) or the oxidation catalyst (Diesel
engine) to heat up more quickly to operat-
ing temperature.For more information on driving, see “Driv-
ing instructions” (

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 le-
ver out ofP orN if the engine speed is high-
er than idle speed. If your foot is not firmly
on the brake pedal, the vehicle could accel-
erate 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.!Simultaneously depressing the acceler-
ator pedal and applying the brake re-
duces engine performance and causes
premature brake and drivetrain wear.
