Opening and Locking
Alarm System
Functionality
The alarm system monitors the following alarm con-
tacts:
–
alarm contacts in doors, trunk lids, convertible
top latch and headlights.
–
Interior monitoring system: movement in the in-
terior when the vehicle is locked, e.g. attempted
theft by smashing a side window.
–
inclination sensor (country-specific equipment:
vehicle inclination (e.g. during towing attempt)).
If one of these alarm contacts is triggered, the horn
sounds for approx. 30 seconds and the emergency
flasher blinks.
After a 5 second interval, the acoustic alarm is trig-
gered again. This cycle is repeated up to ten times
(country-dependent).
Information
Depending on the country, the alarm system is auto-
matically activated 30 seconds after the last door or
the luggage compartment lid is closed, if the vehicle
key has been removed from the ignition lock. Even if
the vehicle has not been locked.
The interior monitoring system and the inclination
sensor are switched off. If a door or the luggage
compartment lid are opened, the alarm is triggered.
