Antitheft Alarm System
The antitheft alarm is automatically
armed or disarmed with the remote
control or any of your vehicle's
mechanical keys by locking or
unlocking the driver's door or the
tailgate.
The antitheft alarm is armed within
approx. 15 seconds after locking the
vehicle.
A blinking lamp (1) indicates that the
alarm is armed.
Operation
Once the alarm system has been armed,
the exterior vehicle lamps will flash and
the alarm will sound when someone:
• opens a door,
• opens the trunk,
• opens the hood,
• attempts to raise the vehicle.
The alarm will last approximately 2
minutes in the form of flashing exterior
lamps. At the same time an alarm will
sound for 30 seconds. The alarm will
stay on even if the activating element
(a door, for example) is immediately
closed.
Note:
We recommend that you carry the
electronic reserve key plus mechanical
key with you and keep it in a safe place
(e.g. your wallet) so that it is always
handy. Never leave the electronic
reserve key in the vehicle.
