Anti-theft alarm
1 Control LED for single lock switch on center console
The alarm system is ready for operation after approximately 15 seconds if the vehicle has been locked with the electronic key or smart card. This is confirmed by the flashing of the control LED "1".
If the vehicle is unlocked using the electronic key or smart card, the hazard warning system is deactivated.
Note: If the vehicle was unlocked with a mechanical key rather than an electronic key or smart card, an alarm will sound.
The alarm can only be turned off by inserting the electronic key into the ignition switch, pressing the buttons
or 
on the electronic key or, if a valid smart card is present, by grasping the door handle or pressing the start/stop button on the selector lever.
The alarm is triggered if, when the anti-theft alarm is operational:
- the door was open,
- the trunk was open,
- the hood was open.
Audible alarm: An additional intermittent audible signal sounds for 30 seconds.
Light warning signal: The warning light signal lights flash for about 5 minutes at double the flashing frequency.
The alarm remains activated even if, for example, an open door is immediately closed.
