Anti-theft alarm system*

Description of anti-theft alarm system*
The anti-theft alarm triggers if unauthorised movements are
detected around the vehicle.
The anti-theft alarm makes it more difficult to break into the vehicle or steal
it. Audible and visible alarms are triggered if the vehicle is opened using
the key, or if unauthorised access to the vehicle is forced.
The anti-theft alarm system is automatically connected on locking the vehi-
cle. The system is then primed.
When does the system trigger an alarm?
The system triggers an alarm if the following unauthorised actions are car-
ried out when the vehicle is locked:
● Mechanical opening of the vehicle with the vehicle key
● Opening a door
● Opening the bonnet
● Opening the tailgate
● Switching on the ignition
● Movements in the vehicle interior
● Undue manipulation of the alarm
● Battery handling
The acoustic signals sound and the turn signals flash for approx. 30 sec-
onds. This may be repeated up to 10 times depending on the country.
Opening the doors mechanically (emergency opening)
If the remote control function fails, you will have to use the key to unlock the
vehicle. This is done as follows:
● Unfold the key by pressing the button shown by the (arrow).
● Use the lock on the driver door to unlock the vehicle. The anti-theft
alarm system remains active, but an alarm is not triggered immediately.
● Switch on the ignition within 15 seconds. When the ignition is switched
on, the electronic immobiliser recognises a valid vehicle key and deacti-
vates the anti-theft alarm system. If you do not switch on the ignition within
15 seconds, the alarm is triggered.
Opening all the doors in manual mode
In vehicles without alarm, when opening the driver door manually all the
doors are opened.
How to switch the alarm off
When the vehicle is unlocked via the unlocking button of the remote control
or when the key is inserted in the ignition lock.
Note
● If, after the alarm goes off, another monitored area is accessed (e.g. the
tailgate is opened after a door has been opened), the alarm is triggered
again.
● Vehicle monitoring remains active even if the battery is disconnected or
not working for any reason.
● The alarm is triggered immediately if one of the battery cables is discon-
nected while the alarm system is active.
Volumetric sensor*
Monitoring or control function incorporated in the anti-theft
alarm* which detects unauthorized vehicle entry by means
of ultrasound.
The system consists of 3 sensors, 2 emitters and a receptor.
