tral position N, particularly if the ignition
is switched o. The automatic gearbox
will not be lubricated and could be dam-
aged.
NOTICE
Never let the brakes “rub” by applying light
pressure to the brake when it is not nec
es-
sary to brake. This will increase levels of
wear.
Troubleshooting

hicle has to be towed, the selector lever
lock must be released manually. Seek ex-
pert assistance.
Emergency program
There is a fault in the system if all the dis-
plays on the instrument cluster for the se-
lector lever positions have a light back-
ground. The automatic transmission is run-
ning in an emergency program. The vehicle
can still be driven in the emergency pro-
gram, but only at reduced speed and not in
all gears.
In vehicles with automatic transmission,
you may no longer be able to select reverse
gear.
1. In all cases, the automatic transmission
should be checked immediately by
a qualified workshop.
Vehicle does not move even though po-
sition is engaged
If the vehicle will not move in the required
direction, the system may have selected
the position incorrectly.
1. Depress the brake pedal and reselect
the position.
2. If the vehicle still does not move in the
required direction, there is a system
fault. Seek expert assistance and have
the system checked.
WARNING
Never release the parking lock when the
elec
tric parking brake is switched o. Oth-
erwise the vehicle could move unexpect-
edly if it is stopped on an incline, which
could lead to accidents and serious inju-
ries.
NOTICE
The automatic transmission will become
dama
ged if the vehicle is allowed to roll for
a long period of time or at a high speed (for
example while being towed) with the se-
lector lever in the neutral position N and
the engine switched o.
