Anti-theft alarm system
The anti-theft alarm system is
operated in conjunction with the
central locking system.
It monitors:
■ Doors, load compartment, bonnet,
■ Passenger compartment,
■ Vehicle inclination, e.g. if it is
raised,
■ Ignition.
Unlocking the vehicle deactivates the
anti-theft alarm system.
Notice
Changes to the vehicle interior, such
as the use of seat covers, could
impair the function of passenger
compartment monitoring.
Activation without monitoring of
passenger compartment and
vehicle inclination
Switch off the monitoring of
passenger compartment and vehicle
inclination, when people or animals
are being left in the vehicle, because
of high volume ultrasonic signals,
movements triggering the alarm and
when the vehicle is on a ferry or train.
