Anti-Theft Alarm System: Notes

The anti-theft alarm system (DWA) detects and indicates attempted intrusions or manipulation on the vehicle.

The DWA monitors the contacts on the doors, the tailgate or split door (R55) and the engine compartment lid as well as the status of the tilt sensor and the interior monitoring (R55: no contacts on Clubdoor).

The alarm system consists of the ultrasonic interior movement detector (USIS) with 2 ultrasonic interior sensors (transmitter and receiver) and the siren with tilt alarm sensor.

If an attempt is made to break into the vehicle and enter the inside of vehicle, a DWA alarm is triggered. The alarm sensor (integrated in the siren) monitors the vehicle inclination. The tilt alarm sensor detects whether the vehicle is lifted or towed.

The DWA alarm is acoustic and visual:

• acoustic alarm via the siren (intermittent tone for approx. 30 seconds)
• optical alarm via the lighting system (hazard warning flashers) for approx. 5 minutes.

The alarm can be coded differently in different national-market versions. For example, the optical alarm output (with hazard warning flashers; with low-beam headlight; with high-beam headlight) and the duration of the alarm (interval: 1x, 3x or 8x).
