Description

The car alarm is part of the car's anti-theft protection and indicates an attempted theft acoustically and visibly. The car alarm function also includes a panic alarm that is activated manually. The alarm logic is contained in the body control module (BCM). The car is available without an alarm or equipped with 3 alternative levels of alarm.

ATA 1 (Anti-Theft Alarm 1)

The anti-theft alarm uses the ordinary door switches and is triggered in case of break-ins through the doors, boot or bonnet plus if +15 is made live when the alarm is armed.

5D: There are glass breakage loops mounted in the rear right and rear left side windows and in the rear window.

The anti-theft alarm uses the car's ordinary horn and direction indicators to indicate a triggered alarm.

ATA (Anti-Theft Alarm)

The anti-theft alarm uses the ordinary door switches and is triggered in case of break-ins through the doors, boot or bonnet plus if +15 is made live when the alarm is armed. It is also triggered if there is any movement in the cabin by means of an ultrasound sensor mounted in the front roof console.

5D: There are glass breakage loops mounted in the rear right and rear left side windows and in the rear window.

The anti-theft alarm uses the car's ordinary horn and direction indicators to indicate a triggered alarm.

ATA 3 (Anti-Theft Alarm 3)

The anti-theft alarm has the same function as ATA. ATA 3 is also equipped with a separate siren and an angle sensor integrated with the ultrasound sensor. The siren's communication with the BCM is monitored. If the communication is broken or disrupted in an "abnormal manner", the siren will detect this and will go off (using its internal battery). The siren is located in the luggage compartment.

An alarm can be retrofitted and ATA can be upgraded to ATA 3.

The anti-theft alarm is always armed using the remote control but can also be set to arm itself when the car doors are closed or when the boot lid is closed. The anti-theft alarm status can be checked with the LED mounted on top of the instrument panel. When the anti-theft alarm is triggered, the BCM will send a bus command, whereby the UEC (underhood electrical centre) will activate the front direction indicators and the car horn. The rear direction indicators are activated by the REC (rear electrical centre). The siren is activated directly by the BCM control module via the communication cable. The interior lighting will be switched on by the BCM when the anti-theft alarm is triggered.
