Automatic gearbox
CAUTION: If the vehicle rolls off in the opposite direction to that of the
engaged gear, the differential may be overloaded or damaged when
the accelerator is pressed.
– Never press the accelerator when the vehicle rolls off in the
opposite direction to that of the engaged gear.
Use of the engine brake
When the engine brake is operated in third gear or higher, the electronics of the
gearbox shifts down to second gear as soon as the engine speed permits it to do so.
This is to allow the engine brake to deliver maximum braking force.
The right number on the selector display shows the second gear selected by the
electronics of the gearbox.
Using PTO
If the vehicle is fitted with a PTO, this can be switched on in both neutral and first gear
(depending on the version).
PTO operation is, however, not permitted in 'D' when the vehicle is held stationary by
the service brake or park brake. Depending on the version, the electronics of the
gearbox shifts the gearbox to neutral to prevent overheating.
11.2 FAULT WARNING
If the transmission fault warning symbol in the master display lights up,
the gearbox oil temperature is too high or there is a fault in the gearbox
(shifting gears).
Oil temperature too high warning
The transmission oil temperature too high warning indicates that the gearbox oil has
reached its maximum temperature. In this situation, the electronics of the gearbox limit
gearbox shifting to the first four gears.
Drive to a safe place as soon as possible, select neutral and let the engine idle at an
increased idling speed. As a result, the cooling system of the engine aims to cool the
gearbox oil.
If, after approximately two minutes the warning in the master display has not
disappeared, turn off the engine and consult a DAF Service dealer.
