Activating the Anti-theft System: Notes

The anti-theft system is activated when the vehicle is centrally locked. Activation can be triggered by the following components:

• Driver's door lock barrel
• ID transmitter
• Outside door handle with Comfort Access (sensitive surface)

After the vehicle has been centrally locked, the emergency power siren is first activated together with the tilt alarm sensor. Then the signals from all door switches, the hood switch and the trunk-lid switch are checked for plausibility. Once the contacts are set, they are then linked to the vehicle monitoring system by the anti-theft system.

The tilt sensor and the ultrasonic interior movement detector must be adjusted to the vehicle's situation each time the vehicle is centrally double-locked. This is called initializing. The tilt alarm sensor delivers information on the vehicle's rest position. If this value is plausible, the tilt alarm sensor is included in the vehicle monitoring process.

The anti-theft system's ultrasonic interior movement detector monitors the passenger compartment. It therefore takes a little time before the ultrasonic interior movement detector can actively be used for the anti-theft system. The ultrasonic interior movement detector is switched to 'activated' approximately 30 seconds after the contacts have been linked to the anti-theft system.
