ATA (Anti-Theft Alarm system)
A visual and audible alarm is triggered if the alarm system is armed and you open:
- a door
- the vehicle with the mechanical key
- the trunk lid/tailgate
- the hood
The alarm is not switched off, even if you close the open door that has triggered it, for example.
If the alarm stays on for more than 30 seconds, the emergency call system mbrace (USA only) or TELE AID (Canada only) initiates a call to the Customer Assistance Center automatically. The emergency call system initiates the call provided that:
- you have subscribed to the mbrace/
TELE AID service.

activated properly.

and GPS are available.
