6 DESCRIPTION AND OPERATION
ENGINE IMMOBILISATION
Engine immobilisation is an important aspect of the
vehicle’s security system, and occurs automatically
whenever the alarm system is armed.
The system also includes a feature known as ’passive
immobilisation’, which is designed to safeguard
thevehicle from theft should the driver forget to arm
the alarm.
Passive immobilisation occurs automatically as
follows:
Thirty seconds after the starter switch has been
turned off and the driver’s door opened.
Five minutes after thestarter switch is turned off or
the alarm system is disarmed.
If the engine has immobilised passively,
re-mobilisation will occur when the starter switch is
turned to position ’II’, provided the handset is on the
same ring as key and in close proximity to the switch.
ALWAYS keep the handset on the same ring as the
key.
NEVER attach both handsets to the same key ring.
Any attempt to start the engine while it is immobilised
will cause the engine immobilisation warning light to
flash.
Engine immobilisation override
If the handset is lost or fails to operate, the engine
immobilisation can be overridden by using the starter
key to enter the four digit emergency access code.
The procedure for entering the code is described after
the following note:
NOTE: If the handset is lost or inoperative,
it is impossible to disarm the alarm. As
soon as the door is opened, the alarm will
sound (continuously for up to three 30 second
periods), and continue while the code is being
entered.
1. With the driver’s door closed, insert the key into
the starter switch.
2. Turn the switch to position ’II’ the required
number of times to enter first digit of code (if first
digit is 4, turn key to position ’II’ and then back to
’0’ four times.
3. Open the driver’s door (to enter first digit) and
then close the door again.
4. Turn the starter switch to position ’II’ and back to
’0’ the required number of times to enter
SECOND digit of code.
5. Open the driver’s door (to enter second digit)
and then close the door again.
6. Turn the starter switch to position ’II’ and back to
’0’ the required number of times to enter THIRD
digit of code.
7. Open the driver’s door (to enter third digit) and
then close door again.
8. Turn the starter switch to position ’II’ and back to
’0’ the required number of times to enter
FOURTH digit of code.
9. Finally, open and close the driver’s door. If the
code has been entered correctly, the anti-theft
indicator light will extinguish, the engine can be
started and the alarm will disarm.
If an incorrect code has been entered:
If the code is entered incorrectly, the anti-theft
indicator light will continue to illuminate and the
engine will fail to start. Before entering the code again,
turn the starter switch to position ’II’, hold in this
position for 5 seconds and then switch off.
After three failed attempts, the security system
invokes a delay period of thirty minutes during which
the system will not accept any further codes.
