Stopping the vehicle
The selector lever can be left in the chosen
gear with the engine running.
When stopping on gradients engage hand
brake or depress brake pedal. To prevent
overheating of the transmission, do not
increase engine revolutions to ensure
smooth idling while standing if a gear
has been selected.
Switch off engine if stopping for a lengthy
period, e.g. in traffic jams or at level
crossings.
Before leaving the vehicle, apply hand
brake, then place selector lever in
position P and remove ignition key.
If the ignition key is not removed, the
battery may be discharged if the vehicle is
then left to stand for a lengthy period of
time.
The ignition key can only be removed when
the selector lever is in position P.

Fault
Control indicator A illuminates when the
ignition is switched on. If it does not go off
after starting or comes on whilst driving,
there is a fault in the automatic
transmission or the engine electronics.
The transmission no longer shifts
automatically. Vehicle can continue to be
driven. Second gear is not available.
Forward gears 1, 3 and 4 must be shifted
manually using selector lever:
1 = 1st gear
2 = 3rd gear
3, D = 4th gear
Have cause of fault remedied. We
recommend that you consult a Vauxhall
Authorised Repairer.
