Automated gearbox
– Rotary knob in position ' D ' (or ' R ').
NOTE: When driving off on a gradient in too high a gear, the automated
gearbox does not change down automatically. If necessary, select a
lower gear manually.
Changing down is only possible by either manually selecting a lower
gear or releasing the accelerator pedal and directly operating it again.
The automatic function shifts down to a lower gear.
NOTE: By default, the gearbox selects the low reverse gear
RL as the
default drive-off gear for reverse driving. If necessary, move the steering
column switch towards '
+ ' to shift the gearbox to the high reverse gear
RH .
Driving off using Hill Start Aid
Driving off on a hill is best done using Hill Start Aid. See section 'Hill Start Aid ' in
chapter 'Driver assist systems'.
Driving off using the park brake
– Release the brake pedal.
– Accelerate (fully).
– Release the park brake when the vehicle is ready to drive off.
WARNING!
– If rolling is unwanted, depress the brake pedal if the accelerator
pedal is not operated.
If the accelerator pedal is not depressed, the vehicle may start to roll.
If rolling is unwanted, this may lead to dangerous situations resulting
in serious injury and damage to the vehicle.
Driving on a gradient
NOTE: If a gear change on a gradient is not preferred, choose the manual
gear control mode. See section 'Manual gear control'.
Now changing down is possible by either manually selecting a lower gear or
releasing the accelerator pedal and directly operating it again. The gearbox
shifts down to a lower gear.
WARNING!
– If prolonged braking is necessary, use the engine brake or, if
present on the vehicle, use the retarder.
If the vehicle rolls and the rotary knob is in position 'N', the driveline is
interrupted and engine braking is not possible. This may lead to
dangerous situations resulting in serious injury or damage to the
vehicle.
