Principle of operation

Alarm system

Your vehicle may be equipped with one of the following alarm systems: Х Perimeter alarm.

Х Perimeter alarm with interior sensors.

Х Category one alarm with interior sensors and battery back-up sounder.

Х 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
Interior sensors

WARNING:
The sensors in the interior lamp unit 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 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:
Х If someone opens a door, the tailgate or the bonnet without a valid key or remote control.

Х If someone removes the audio or navigation system.

Х If the ignition is turned to position I, II or III without a valid key.

Х If the interior sensors detect movement within the vehicle.

Х On vehicles with a battery back-up sounder, if someone disconnects the vehicle battery or the battery back-up sounder itself.

Х If the tilt sensors detect a change in the inclination of the vehicle.

If the alarm is triggered, the alarm horn will sound for 30 seconds and the hazard warning flasher will flash for five minutes.

Any further attempts to perform one of the above will trigger the alarm again.

Full and reduced guard

Full guard

Full guard is the standard setting.

In full guard, the interior and tilt sensors are activated when you arm the alarm.

Note: This may result in false alarms if animals or moving objects are inside the vehicle or, on vehicles with tilt sensors, when travelling on a ferry.

Reduced guard

In reduced guard, the interior and tilt sensors are deactivated when you arm the alarm.

Note: You can set the alarm to reduced guard for the current ignition cycle only.

The next time you switch on the ignition, the alarm will be reset to full guard.

Ask on Exit

You can set the information display to ask you each time which level of guard you wish to set.

If you select Ask on Exit, the message Reduced guard? appears in the instrument cluster display each time you switch the ignition off.

If you wish to arm the alarm with reduced guard, press the OK button when this message appears.

If you wish to arm the alarm with full guard, leave the vehicle without pressing the OK button.

Selecting full or reduced guard

Note: Selecting Reduced does not set the alarm permanently to reduced guard.

It sets it to reduced guard only for the current ignition cycle. If you regularly set the alarm to reduced guard, select Ask on Exit.
