Unlocking the Luggage Compartment
The tilt alarm sensor and USIS are blanked out if the luggage compartment is unlocked
and opened on an armed vehicle since loading the vehicle could bring about a new vehi-
cle status. The initialization procedure for the USIS and tilt alarm sensor is resumed 3
sec after closing the trunk lid.
Forced Disarming
The anti-theft alarm system is disarmed when a person remains in the vehicle and sets
the vehicle central arrest function via the remote control.
The CAS2 recognizes the remote control if it is now inserted in its holder. The CAS2
sends the "locked" message via the K-CAN and the Anti-theft alarm system is disarmed.
No Crosswise Operation
If crosswise operation is not implemented (coded - vehicle profile), an alarm is triggered
when the anti-theft alarm system is armed or disarmed. This applies to arming with the
remote control and disarming via the lock barrel in the driver's door.
The CAS2 detects the unlock status via the driver's door lock barrel, however, it does not
unlock the vehicle. The anti-theft alarm system remains armed and triggers the alarm
when the driver's door is opened.
This function is coded in the CAS2.
Feedback from Anti-Theft Alarm System
When arming, the anti-theft alarm system provides feedback only when all doors, hood
and trunk lid are closed.
Visual feedback is provided via the hazard warning lights or the DWA LED.
Feedback via DWA LED
For the vehicle user, the DWA LED serves as an indicator showing the status of the Anti-
theft alarm system.
When flashing, the DWA LED is driven at a frequency of 0.5 Hz and the ON-interval is
60 ms.
When blinking, the DWA LED is driven at a frequency of 2 Hz.
