Note that if the system is armed when a door, engine lid or front bonnet is not fully closed, a buzzer will
sound continuously until the opening is secured. If still open after 40 seconds, the siren will sound.
After arming the system, a period of at least 40 seconds must elapse before all functions and sensors
become fully active. After this time, the alarm will be triggered by any of the following actions:
Opening a door, engine lid or front bonnet;
Movement detected within the cockpit;
Energising the ignition circuit ('hot wiring').
When triggered, the electronic siren will sound and the hazard warning lamps will flash for a period of
approximately 30 seconds before closing down and resetting, ready for any further triggering input. If the
engine lid or front bonnet are left open, the alarm will repeat after a short delay, and continue in this sequence
for a total of ten cycles.
To silence the siren when the alarm has been triggered, press once the larger of the two buttons on the
transmitter key. The siren will reset and the system will remain armed.
Disarming the Alarm
To disarm the alarm prior to entering the vehicle, press once the larger of the two buttons on the transmit-
ter key. This command will be acknowledged by:
One flash of the hazard warning lamps;
Extinguishing of the alarm tell tale in the instrument panel. (If the tell tale is flashing intermittently, the
alarm has been triggered during the armed period - see 'Trouble Shooting')
Passive Immobilisation
In order to provide a measure of automatic vehicle security, independent of any driver initiative, the
system will 'passively' immobilise the engine's cranking and running circuits either;
four minutes after switching off the ignition;
or one minute after switching off and opening and closing a door.
Immobilisation will be indicated by:
the alarm tell tale flashing.
and if initiated by the door being opened and closed: two flashes of the hazard warning lamps.
Note that these indications are the same as those for the arming of the alarm, but in this instance it is only
engine immobilisation which is activated.
To start the car after immobilisation has been activated, it is necessary to switch OFF the ignition and
press once the large button on the transmitter key. The alarm tell tale will be extinguished.
Intrusion Sensing
A hyperfrequency radar detector, mounted at the rear of the centre tunnel, is able to detect substantial
movement within the cockpit and trigger the alarm in the event of unauthorised intrusion. The range and
sensitivity of the intrusion sensor may be adjusted if necessary - see page 6.
If an animal is to be left in the vehicle when the alarm is armed, it is necessary temporarily to switch off
the intrusion sensing by the following procedure:
Arm the system in the usual way by pressing once the large button on the transmitter.
Within 40 seconds, press once the smaller button on the transmitter. This action will be acknowledged by
a single buzz of the buzzer.
Note:
# Intrusion sensing will automatically be reinstated the next time the alarm is armed.
# Do not inhibit operation of the radar detector by placing bags or large objects against the sensor.
Summary of Alarm Normal Operation
In normal use, whenever leaving the car, close both lids, lock the doors using the key, and press once the
transmitter large button to arm the alarm - acknowledged by two hazard lamp flashes, and the alarm tell tale
flashing. Check that two hazard flashes occur and not one (see below).
On return to the car, whether or not the alarm is armed, again press once the transmitter large button.
This will either disarm the alarm, or, if the alarm was not armed, the passive immobilisation will be switched off.
In both cases, this will be acknowledged by one hazard lamps flash and the alarm tell tale going out.
