Operation

The V.A.S. (Vehicle Alarm System) anti-theft system is a system which offers volumetric and perimeter type protection, it is, in effect, capable of checking the state of the doors and for the presence of a moving object inside the passenger compartment.

In particular, it is capable of:

• - adapting its operation to the laws in force in the various markets which regulate the use of alarm systmes;
• - distinguishing intermittent and permanent errors or faults;
• - memorizing the number of times the anti-theft device is activated and the number of times the alarm is set off;
• - detecting and memorizing specific faults in the control unit;
• - detecting the faults or problems in the system de-activating switch connecting cables.

The anti-theft system is basically composed of: a receiver in the courtesy light, a transmitter (remote control) in the key, volumetric sensors, door/bonnet lid switches and an electronic control unit, located in the engine compartment opposite the battery drip tray, which completes the alarm and the key operated emergency switch (ON-OFF).

OPERATION

Switching On - Switching Off

The anti-theft device is ACTIVATED by pressing the central locking remote control transmitter switch. The operating range is about 5 m.

The DEACTIVATION is obtained by pressing the switch on the remote control again.

It is not possible to switch on the anti-theft device with the ignition switch in the ON position, but only with it in the OFF or PARK positions.

The transmitter is an infra red device where the code is constantly transmitted whilst the switch is pressed for a maximum of 5 seconds. For the maximum efficiency of the anti-theft device it is advisable to direct the remote control device towards the courtesy light in the ceiling and keep the transmitter switch pressed until it has switched on or off signalled by the LED and, in certain countries where the law permits, a visual and audible signal.

Excluding the system

If the transmitter batteries are discharged or the anti-theft system is not working properly it is possible to de-activate the alarm via the emergency key located in the control unit (OFF position).

When the vehicle is handed over, check that the emergency switch in the control unit is in the ON position.

Turn the key to the OFF position if the vehicle is not used for long periods (more than 1 month). When the key is turned to the ON position, if the battery charge is insufficient or if the control unit has been disconnected, the anti-theft device will give out an intermittent audible signal, 10 beeps, (except for the system programmed for Germany).

Surveillance

During the surveillance the LED flashses at a frequency of 0.8 Hz.

In this state the anti-theft system:

• - surveys the doors, the bonnet lid and the tailgate;
• - surveys a disconnection of the battery/cables cut;
• - surveys the non authorized switching on of the ignition switch;
• - surveys movements inside the passenger compartment (volumetric surveillance);
• - deactivates the electronic injection control unit (if connected).
