Updated 2023-06-08

The alarm is armed when the vehicle is locked.

Arming the alarm

Lock and arm the vehicle by:

pressing the lock button on the remote key
touch the marked surface on the outside of the door handle or the rubberized pressure plate on the trunk lid1.

If the vehicle is equipped with both keyless locking/unlocking* and power trunk lid, the button P5-1507 Power Operated Tailgate - close and lock button on the lower edge of the trunk lid can also be used to lock and arm the vehicle.

Disarming the alarm

Unlock and disarm the vehicle alarm by:

pressing the unlock button on the remote key
grip a door handle or press the trunk lid's rubberized pressure plate1.

Disarming the alarm without a functioning remote key

The vehicle can be unlocked and disarmed even if the remote key is not functioning, e.g. if the battery is discharged.

Open the driver's door using the detachable key blade.

This will trigger the alarm.

Note

Remember that the alarm is armed when the vehicle is locked.
The alarm will be triggered if any of the doors is opened from the inside.

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 Car → Locking.

Select Passive Arming Deactivation to temporarily deactivate the function.
