Activation possibilities

The anti-theft alarm (ATA) can be activated or armed as follows:

 From outside manually at driver's door lock with key

 From inside manually with ATA/panic alarm button

 With radio frequency remote control

Moreover, the ATA has an automatic arming feature depending on the parameter settings.

After arming the anti-theft alarm (ATA), all relevant switches, sensors and interface inputs are monitored as a matter of principle.

Status feedbacks

If all systems are OK and all prerequisites fulfilled, activation of the alarm system is acknowledged accordingly.

Depending on type of activation, acknowledgment is accomplished by actuating the turn signal indicators, alarm siren or status LED in ATA/panic alarm button (S59).

If acknowledgment is not accomplished, check vehicle doors, stowage compartment, front hatch and cab for proper locking.

In the event of a sensor malfunction, acknowledgment is also not accomplished.

In such cases, a corresponding message is indicated for the alarm source(s) to be checked in the instrument (P2).

 The anti-theft alarm (ATA) is active even when acknowledgment is not accomplished.However, only the functional alarm inputs are evaluated for alarm sensing.
