HANDSET INITIALISATION
NOTE: New handsets are supplied in pairs.
If a new handset is required, it will require
initialisation to the ECU using the
following procedure:
1. Starting conditions: ignition off, doors unlocked,
bonnet switch depressed.
2. Carry out instructions 3. to 9. within 8 seconds.
3. Switch ignition ON.
4. Switch ignition OFF.
5. Lock doors.
6. Unlock doors.
7. Release bonnet switch.
8. Switch ignition ON.
9. Switch ignition OFF.
If alarm is correctly accessed, horn will sound and
LED will light. It is now possible to programme two
handsets of correct frequency to vehicle alarm ECU.
This must be carried out within two minutes.
10. Press and hold down button on first handset until
dash LED flashes.
11. Repeat instruction 10. for second handset.

CENTRAL DOOR LOCKING
Where electrically operated central door locking is
fitted, locking or unlocking the drivers door from
outside by key operation, or from the inside with the
sill knob automatically locks or unlocks the passenger
and rear doors.
Front and rear passenger doors can be independently
locked or unlocked from inside the vehicle by sill knob
operation but can be overidden by further operation of
the driver’s door locking control.
On rear doors, where side facing fold down seats are
fitted, a child safety lock is provided which can be
mechanically pre-set to render the interior door
handles inoperative.
Failure of a door actuator will not affect the operation
of the remaining doors and the door with the
inoperative actuator can still be locked or unlocked
manually.
The actuator unit fitted to the driver’s door is the
master actuator and is identified from the actuators
fitted to the passenger and rear doors by having a
white connecting link, whereas the passenger and
rear door actuators have grey coloured connecting
links.
NOTE: Actuator units are non-servicable, if
a fault should occur replace the unit with a
new one.
