WARNING
Observe the safety warnings ››› in Gear
selector positions on page178.
●
Never allow the brake to rub and do not use
the brake pedal too often or for long peri-
ods, as the brakes can overheat. This reduces
the braking power, increases the braking dis-
tance or even causes a brake system fault.

cle’s brakes applied with the brake pedal or
parking brake.

In certain driving situations or traic con-
ditions, the gears could overheat and be
damaged! If the warning lamp lights up,
stop the vehicle as soon as you can and wait
for the gearbox to cool ›››page182.
●
If the gearbox operates in emergency
mode, have the fault repaired by a specialist
workshop without delay.
Kick-down
The kick-down device provides maximum ac-

The shift to the next higher gear will not take
place until the preset maximum engine RPM is
reached.
WARNING

or wet, the kickdown feature could cause the
driving wheels to spin, which could result in
skidding.
