Although the alarm system draws only a tiny current, if the vehicle is to be parked for an extended period
of time (over three weeks in summer, or two weeks in winter), it is recommended to reduce current drain to a
minimum by switching off the alarm system with the override key, and utilising other security measures, includ-
ing the (automatic) immobilisation feature, as may be deemed appropriate.
The override facility may also be used in order
to allow recovery of the vehicle in extreme condi-
tions, for example if both transmitter key batteries
have been allowed to run down, or are lost or faulty.
The immobilisation feature will remain operative and
must be overridden by switching on the ignition and
inserting the immobiliser touch key into its socket
on the side of the column shroud for about a second
until the adjacent LED is extinguished. In order to
protect against the loss of all keys, it is essential that
the alarm override keys and immobiliser touch keys
are kept separate from the transmitter keys, but the
owner should be reminded that if the car is to be left
for servicing or repairs, the override key must be
available to the technician.

Dynamic Transmitter Coding: Each time a transmitter key is used, the coding in both transmitters and the
control unit is changed for optimum code copying protection. When using a transmitter which was not last used
to operate the system, it will be necessary on the initial command, to press the red button twice in order to
synchronise the codes in the three elements. Be sure to press the button for a whole second to allow the
complete code to be transmitted.
Functional Test: To test that the alarm system is operating correctly, carry out the following test procedure:
1. Arming the System:
a). Ensure that the front bonnet, engine lid and both doors are fully closed.
b). Open the driver's window.
c). Press once, the transmitter embossed red button (if the battery has been disconnected, press the
button twice for a full second each time).
Two flashes of the turn indicators and two buzzes? (YES)
Illumination of the alarm LED constant? (YES)
2. Door, Front Bonnet & Engine Lid Switches (all actions must be within 30 seconds of arming or siren will
sound):
a). Open driver's door; Buzzer sounds? (YES).
b). Open passenger's door; Buzzer sounds? (YES).
c). Open front bonnet; Buzzer sounds? (YES).
d). Disarm system.
e). Open engine lid.
f). Arm system; Buzzer sounds? (YES).
g). Close engine lid; Buzzer stops? (YES).
3. Disarming the System:
Press once the transmitter embossed red button;
One flash of the direction indicators, one short and one long buzz? (YES).
Alarm LED changes to flashing state? (YES).
4. Microwave Sensor Setting and Test (The sensitivity of the microwave sensor is pre-set and should re-
quire no adjustment):
a). Open the driver's window, close all doors, lids and roof, and arm the system.
b). Wait for 20 seconds before moving an arm slowly through the open window towards the gear lever.
Buzzer sounds? (YES).
c). Disarm, then re-arm the system and wait for 20 seconds.
d). Wave an arm just above the roof and windscreen.
