Alarm
PRINCIPLE OF OPERATION
Alarm system
Your vehicle may be equipped with one
of the following alarm systems:
• Perimeter alarm.
• Perimeter alarm with interior
sensors.
• Category one alarm with interior
sensors and battery back-up
sounder.
• Category one alarm with interior
sensors, battery back-up sounder
and tilt sensors.
Perimeter alarm
The perimeter alarm is a deterrent
against unauthorised access to your
vehicle through the doors and the
bonnet. It also protects the audio unit.
Interior sensors
WARNING
The sensors must not be covered
up. Do not activate the alarm with
full guard if any persons, animals or other
moving objects are inside the vehicle.
The sensors act as a deterrent against
E1290 0 5
unauthorised intrusion by sensing any
movement within the vehicle.
Battery back-up sounder
The battery back-up sounder is an extra
alarm system which will sound a siren
when the alarm is triggered. It is armed
directly when you lock the vehicle. The
sounder has its own battery and will
sound an alarm siren even if someone
disconnects the vehicle battery or the
battery back-up sounder itself.
Tilt sensors
The tilt sensors detect if someone
attempts to steal a wheel or tow the
vehicle away by sensing changes in the
inclination of the vehicle.
Note: When travelling on a ferry with the
alarm armed, deactivate the tilt sensors
by selecting reduced guard. This will
prevent the alarm from being triggered
by the movement.
Triggering the alarm
Once armed, the alarm is triggered in
any of the following ways:
• If someone opens a door, the
tailgate or the bonnet without a valid
key or remote control.
• If someone removes the audio or
navigation system.
• If the interior sensors detect
movement within the vehicle.
• On vehicles with a battery back-up
sounder, if someone disconnects
the vehicle battery or the battery
back-up sounder itself.
• If the tilt sensors detect a change in
the inclination of the vehicle.
