Automated gearbox
CAUTION: The vehicle speed may increase when travelling downhill.
In fully automatic mode, the automated gearbox selects a higher gear
to protect the engine against excessive engine speed. If the gearbox is
in manual mode, the engine speed can exceed the maximum permitted
engine speed. This can lead to serious damage to the engine.
– If the gearbox is in manual mode, select a higher gear manually to
prevent the engine from exceeding the maximum engine speed (red
area of the rev counter).
CAUTION: The clutch is continuously slipping when driving in the
manoeuvring mode. Driving in this mode may lead to clutch overload
or damage.
– Only use the manoeuvring mode for actual manoeuvring.
– Never use the manoeuvring mode for normal driving on a level
road, on a gradient or when driving over heavy terrain.
– The exception to this is driving on snowy roads when all traction
increasing aids (such as increasing the wheel slip with ASR switch,
lifting trailing axle and so on) have been applied and the driven
wheels still have no traction, in which case the manoeuvring mode
can be used on flat roads only.
Try to make a path by rocking the vehicle backwards and forwards.
To do this, select the forward and reverse manoeuvring mode
alternately while giving a little throttle. Keep the vehicle in motion
by using the moving weight of the vehicle.
Only use the manoeuvring mode in this way for a few moments to
avoid overloading the clutch.
10.7 OFF-ROAD MODE
If a vehicle is equipped with the off-road application, a second shifting program can be
selected.
This shifting program is tuned especially for driving off-road (heavy conditions), and can
be selected with a switch on the dashboard.
This means that besides the on-road shifting program, an off-road shifting program can
be selected.
Engaging and disengaging the off-road mode
Press this switch to engage or disengage the off-road mode of the
automated gearbox.
A green indicator light in the switch indicates that the off-road mode
function is activated.
Driving in the off-road mode
The off-road mode is only available when the automated gearbox rotary knob is in
position D (Drive) or R (Reverse).
When the off-road mode is selected, the behaviour of the gearbox changes.
