28 Keys, doors and windows
However, the doors may not be
unlocked if mechanical problems
occur with the door locking system or
vehicle battery.
Immobiliser
The immobiliser system provides an
additional theft deterrent to the
vehicle in which it is installed and
prevents it from being started by
unauthorised persons. The valid key
for a vehicle equipped with an
immobiliser system is an ignition key
with integrated transponder, which is
electronically coded. The
transponder is placed invisibly in the
ignition key.
Only valid ignition keys can be used
to start the engine.
Invalid keys may only open the doors.
The engine is automatically
immobilised after the key is turned to
LOCK and has been removed from
the ignition switch.
If the immobiliser system detects a
fault when the ignition switch is in ON
position, the immobiliser indicator will
flash or illuminate and the engine will
not start.
Have the vehicle checked by your
authorised repairer.
Note
Tap the key lock or heat the key if the
door does not open due to a frozen
key slot in the event of cold weather
conditions.
