Headlight unit
2With the bonnet supported in its open
position, loosen (but do not remove) the screw
located above the front direction indicator.
3Withdraw the front direction indicator unit
forwards, and disconnect the wiring multi-
plug. Place the unit to one side.
4Disconnect the wiring multi-plug for the
headlight unit (see illustration).
5Remove the radiator grille as described in
Chapter 11.
6Remove the front bumper as described in
Chapter 11.
7The headlights fitted from new are a single
unit, joined by a plastic back-piece running
across the front of the vehicle. However, if it is
required to renew a headlight unit on one sideonly, the back-piece must first be removed
complete, then cut in half on the bench.
8Unscrew the mounting bolts from each side
of the headlight unit, and withdraw the unit
from the front of the vehicle (see
illustrations). Use a hacksaw to cut through
the centre of the headlight unit (ie between the
two headlights), and obtain a connecting kit
from a Ford dealer to attach the new unit.
9If necessary, the lens may be removed
separately by releasing the clips (see
illustrations). To remove the diffuser, release
the clips, then remove the rubber seal.

Rear light cluster
16With the tailgate or bootlid open, unhook
the parcel net (where fitted) from the rear of
the luggage compartment.
17On Saloon and Hatchback models,
remove the screws, release the clips, and
remove the trim panel from the rear cross
panel. On Estate models, it is sufficient to
open the flap.
18Remove the screws, and press the rear
light trim cover from the guides (where
applicable).
19Disconnect the wiring multi-plug.
20Unscrew the four mounting nuts, and
withdraw the light unit from the outside of the
vehicle (see illustrations).

21Remove both number plate lights as
described in Section 5.
22With the tailgate or bootlid open, remove
the screws and withdraw the inner trim panel.
23Unscrew the nuts, and remove the outer
cover and number plate base from the
tailgate.
24Disconnect the multi-plug and remove the
light assembly.
Refitting
25Refitting of all the external light units is a
reversal of the removal procedure, noting the
following points:(a) When refitting the rubber seal on the
headlight unit, note that it has a tapered
seat.
(b) If one or both headlights have been
disturbed, have the beam alignment
checked as described in the next Section.
(c) When refitting the rear light cluster, check
the condition of the sealer on the body
panel, and if necessary renew it.
1Accurate adjustment of the headlight beam
is only possible using optical beam-setting
equipment. This work should therefore be
carried out by a Ford dealer, or other service
station with the necessary facilities.
2Temporary adjustment can be made after
renewal of a headlight bulb or unit, or as an
emergency measure if the alignment is
incorrect following accident damage. Turn the
adjustment screws on the top of the headlamp
unit to make the adjustment (see illustration).
3Before making any adjustments to the
settings, it is important that the tyre pressures
are correct, and that the vehicle is standing on
level ground. Bounce the front of the vehicle a
few times to settle the suspension. Ideally,
somebody of average size should sit in the
driver’s seat during the adjustment, and the
vehicle should have a full tank of fuel. Where a
vehicle is fitted with an electrical beam
levelling system, set the switch to the “O”
position before making any adjustments.4Whenever temporary adjustments are
made, the settings must be checked and if
necessary reset by a Ford dealer or other
qualified person as soon as possible.
Removal
1Remove the headlight unit as described in
Section 7, then remove the cover.
2Disconnect the wiring multi-plug from the
motor.
3Rotate the motor upwards approximately
60°, then pull it forwards slightly.
4Disconnect the adjustment spindle by
pressing the ball coupling to one side, away
from the socket on the reflector.
5Withdraw the motor from the headlight unit.
Refitting
6Refitting is a reversal of the removal
procedure, but make sure that the motor is
turned down until it engages the stop.

26Remove the lower facia panel from under
the steering wheel.
27Unclip the bulb failure module and
disconnect the multi-plug.
Note: From November 1993, for added
security, a complex Bosch immobiliser system
was fitted to some models. For further details,
refer to your Ford dealer.
1All UK models are fitted with an anti-theft
alarm system, incorporating movement
sensors and an ignition immobiliser. The
system is activated when the vehicle is
locked.
2The system includes a start inhibitor circuit,
which makes it impossible to start the engine
with the system armed.
3The movement sensors consist of two
ultrasonic units, located in the “B” pillars,
incorporating transmitters and receivers (see
illustrations). The receivers check that the
echo frequency matches the original
frequency. If there is any significant
difference, the system triggers the alarm.

4The system module is located on a bracket
beneath the right-hand side of the facia. The
set and reset switches are located in a
housing by the lock barrel holder in the doors,
tailgate or bootlid.
5To allow temporary opening of the tailgate
or bootlid, an inhibit switch is fitted to the lock
barrel. This suppresses the alarm system until
the tailgate or bootlid is closed again.
6Where remote central locking is fitted, an
infra-red receiver is located on the exterior
door handle (see illustration). Note that
excessive heat can destroy this receiver;
therefore, it should be covered with aluminium
tape if (for instance) a paint-drying heat
process is to be used.
7The alarm system is fitted with its own horn.
On Hatchback and Saloon models, it is
located on the left-hand side of the luggage
compartment; on Estate models, it is located
on the right-hand side of the luggage
compartment (see illustration).
8The alarm system incorporates a self-test
function, which can be activated by operating
the bonnet switch or one of the lock position
switches eight times within 10 seconds.
During the check, the horn or buzzer issues
acoustic signals which should occur every
time a door, bonnet or tailgate is opened. If
the doors are double-locked, the signal will
occur when something is moved within the
passenger compartment. A more
comprehensive test can be made using the
Ford FDS 2000 diagnostic tester.
9The door lock switches associated with the
alarm system are located behind the door trim
panels (see illustration).
1Cruise control is available as an option on
some models.
2The cruise control system components are
shown in the accompanying illustration (see
illustration). The system is active at road
speeds between 25 mph and 125 mph.
3The system comprises an electronic speed
