Alarm System
The alarm system monitors the following alarm
contacts:
– Alarm contacts in doors, tailgate and hood
– Passenger compartment monitoring system:
Movement in the interior when the vehicle is
locked, e.g. attempted theft by breaking a
window
– Inclination sensor: Vehicle incline (e.g., during an
attempt to tow the vehicle away)
– Diagnostic socket
– Trailer hitch socket
If one of these alarm contacts is triggered, the alarm
horn sounds for approx. 25 seconds and the emer-
gency flasher flashes for approx. 300 seconds.
After a 5 second interval, the acoustic alarm is trig-
gered again. This cycle is repeated up to ten times
(country-dependent).
