Faults
If the electronic unit in the automatic gearbox
registers a fault, a warning will be activated.
If the vehicle is started during an active warning,
the electronic unit will lock the automatic gearbox
in the neutral position. The automatic gearbox will
no longer respond to gear-lever movements from
the neutral position.
If a fault occurs while driving, a warning is
activated. The electronic unit decides whether the
automatic gearbox:
- is locked in the gear in which the fault
occurred;
- is restricted as regards changing up and
down;
- ceases to respond to changes from the
selector lever;
- ceases to respond to changes from the
selector lever from the neutral position.
During a fault changes of direction may no longer
be possible.
During a fault the vehicle can be brought to a halt
in a safe place. When the ignition is switched off,
the automatic gearbox is locked in the neutral
position.
Towing
To tow a vehicle, the prop shaft must be detached
at the rear axle. It is also possible to remove the
axle shafts. As oil can be lost in this process, it
must be avoided as much as possible owing to
environmental concerns.
Towing the vehicle without taking
the above into consideration may
lead to serious damage to the
gearbox.
