Automated gearbox
Engaging and disengaging the liquid transport application
Press this switch to engage or disengage the liquid transport application.
Drive-off gear
The modified gear shift strategy also sets the third gear as the default driving-off gear.
Driving off in third gear makes sure that the vehicle starts moving more smoothly than
in a lower gear. This results in less movement of the liquid.
NOTE: It is recommended to use Hill Start Aid when driving with backward
and forward moving loads, for example oscillating liquid in a tank. For more
information, see section 'Hill Start Aid' in chapter 'Driver assist systems'.
10.9 CLUTCH PROTECTION
Flashing gear indication on master display
NOTE: To protect the clutch the automated gearbox is equipped with a
drive-off protection. This protection prevents operation of the clutch and
gearbox at transmission oil temperatures below - 20°C.
Warming up the transmission oil can be speeded up by increasing the
engine's rpm.
NOTE: With every engine start the automated gearbox performs
preliminary checks. These checks can result in a delay in selecting the drive
off gear.
During these preliminary checks revving up the engine is not possible.
If the vehicle is at standstill for a prolonged period with a gear engaged, a flashing gear
indication may be displayed on the master display. Relieve the clutch by setting the
gearbox selector switch to N (neutral).
If this is ignored, the gearbox automatically shifts to neutral (the flashing gear indication
on the master display stays active). Before driving off again it is now necessary to set
the gearbox selector switch to N (neutral) first and subsequently select the desired
gear.
Overload warning on master display
When the clutch is overloaded, a yellow warning 'Clutch overload'
appears in the master display.
Relieve the clutch by:
– increasing the vehicle speed (driveline is closed) by further pressing in the
accelerator pedal.
