Manual gearbox
The warning indicator on
the instrument panel
lights up when the low
splitter position is
engaged.
9.5 CHANGING GEAR ON AN INCLINE
Depending on the vehicle model, the following recommendations result in favourable
economies when driving on gradients:
Do not reduce speed more than is necessary at the beginning of a gradient.
If necessary, accelerate to full throttle.
Shift down until the engine speed stays in the green area of the rev counter. Do not
instantly shift down if the engine speed suddenly drops.
Shift up as soon as the engine speed increases on the incline.
Depending on the steepness of the incline, shift down at a lower engine speed or
shift up at a higher engine speed.
Only drive in the top semi-green area of the rev counter momentarily in case of
pulling through in a gear for skipping more gears with a fully laden vehicle on a
slope.
Do not change gear if the vehicle ‘holds its speed’ in the green area of the rev
counter.
9.6 CLUTCH PROTECTION
Driving off in too high a gear puts excessive stress on the clutch.
Clutch protection system
Depending on the vehicle configuration, a clutch protection system can be present. The
clutch protection system prevents the vehicle from driving off in gear positions other
than 1 and reverse (both split low and high).
If a higher gear is selected to drive off in, a yellow warning 'Drive-off
gear too high' is activated and the accelerator pedal is deactivated.
