Automatically arming and disarming the alarm

Automatically arming the alarm helps prevent inadvertently leaving the vehicle without alarm protection.

If the vehicle is unlocked using the remote key (and the alarm is disarmed) but none of the doors or trunk lid is opened within two minutes, the alarm will be automatically rearmed. The vehicle will also re-lock.

On some markets, the alarm will be automatically armed following a slight delay after the driver's door has been opened and closed without being locked.

To change this setting:
Tap Settings in the center display's Top view.
Tap My CarLocking.
Select Passive Arming Deactivation to temporarily deactivate the function.
