Integrating Trailer in Anti-Theft Alarm System

If the vehicle was delivered from the factory with an Anti Theft Warning System (ATWS) and a trailer hitch, a trailer can be integrated into the switched on ATWS.

Activating Anti-Theft Alarm System

- Insert trailer connector completely into vehicle trailer socket.

- Lock vehicle.

Anti-theft alarm system is then activated immediately. Trailer is now integrated in the ATWS.

• An alarm is triggered as soon as the electrical connection to the trailer is interrupted with the vehicle locked.

Deactivating Anti-Theft Alarm System

• Anti-theft alarm system is deactivated when the vehicle is unlocked via the unlock button on radio-frequency remote control, or

• when vehicle is opened via Keyless Access, or

• when the ignition is switched on.

Unlocking Vehicle Mechanically (Emergency Opening)

- Unlock vehicle at driver door.

Anti-theft alarm system remains activated, however no alarm is triggered.

- Switch on ignition within 15 seconds.

• If the ignition is not switched on after 15 seconds the alarm is triggered.

By switching on the ignition, the electronic immobilizer recognizes a valid vehicle key and deactivates the anti-theft alarm system.
