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
control unit with integral actuator and

switches mounted in the engine compartment
with a control cable connected to the throttle
valve actuator, driver-operated switches,
brake and clutch pedal switches, an indicator
light, and a road speed sensor.
4The driver-operated switches are mounted
on the steering wheel, and allow the driver to
control the various functions.
5The vehicle speed sensor uses the
speedometer cable drive pinion to generate
pulses which are fed to the speed control unit.
6The stop-light switch, brake pedal switch
and (when applicable) clutch pedal switch are
used to disable the cruise control system. The
stop-light switch is activated when the brake
pedal is applied gently, and the brake pedal
switch is activated when the brake pedal is
applied forcibly.
7An indicator light on the instrument panel is
illuminated when the system is in operation.
8The following paragraphs describe brief
removal procedures for the cruise control
system components. The battery negative
(earth) lead should be disconnected before
commencing work (refer to Chapter 5, Sec-
tion 1). Refitting is a reversal of removal.

clutch switch, brake pedal switch and stop-
light switch.
14To remove the clutch and brake pedal
switches, twist them anti-clockwise. To
remove the stop-light switch, twist it
clockwise (see illustration).
15Refitting is the reverse of removal. To
ensure correct operation of the brake pedal
switches, reset the switch by fully extending
its plunger (see illustration).Depress the
pedal until the distance between it and the
mounting bracket is as shown in Chapter 9,
illustration 25.6. Hold the pedal in this
position, clip the switch securely into position
and gently raise the pedal to the at-rest
position. This will automatically set the
position of the switch.
Speed control actuator
16Remove the air cleaner as described in
Chapter 4.
17Disconnect the actuator cable from the
throttle linkage on the throttle housing, by
releasing the inner cable end fitting from the
segment and unclipping the outer cable from
the bracket.
18Unscrew the actuator mounting bolt, thenslide the actuator out of the mounting pin
holes.
19Disconnect the multi-plug and remove the
assembly.
20Depress the actuating cable cap locking
arm, and remove the cap by turning it anti-
clockwise (see illustration).
21Gently raise the cable retaining lug by a
maximum of 0.5 mm, and push the cable end
out of the slot in the pulley.
22When refitting, make sure that the cable
end locks into the slot in the pulley.
23To locate the cable cap onto the actuator
pulley, keep the cable taut and in the pulley
groove, and pull the throttle linkage end of the
cable to draw the cable cap onto the pulley.
24To refit the cable cap, keep the cable taut
and the pulley still, then refit the cable cap
tabs into the actuator slots; turn the cap
clockwise until the locking arm locates on the
locking stop. Note:Incorrect assembly of the
cable onto the pulley may result in a high idle
speed. Check that the throttle lever is in its
idle position after refitting the actuator.

procedure. In the case of the washer nozzles,
press them in until they are fully engaged. The
rear window washer nozzle must rest against
the rubber seal.
Note:Special tools are required to remove the
radio.
Coding
1If a Ford “Keycode” unit is fitted, and the
unit and/or the battery is disconnected, the
unit will not function again on reconnection
until the correct security code is entered.
Details of this procedure are given in the
“Ford Audio Systems Operating Guide”
supplied with the vehicle when new, with the
code itself being given in a “Radio Passport”
and/or a “Keycode Label” at the same time.
2For obvious security reasons, the re-coding
procedure is not given in this manual - if youdo not have the code or details of the correct
procedure, but can supply proof of ownership
and a legitimate reason for wanting this
information, the vehicle’s selling dealer may
be able to help.
3Note that these units will allow only ten
attempts at entering the code - any further
attempts will render the unit permanently
inoperative until it has been reprogrammed by
Ford themselves. At first, three consecutive
attempts are allowed; if all three are incorrect,
a 30-minute delay is required before another
attempt can be made. Each of any
subsequent attempts (up to the maximum of
ten) can be made only after a similar delay.
Removal
4Disconnect the battery negative (earth)
lead.
5Where fitted, prise the cover/surround from
the front of the radio/cassette player. Note
that the cover is not fitted to all models.
6In order to release the radio retaining clips,
two U-shaped rods must be inserted into the
special holes on each side of the radio (see
illustration). If possible, it is preferable to
obtain purpose-made rods from an audio
specialist, as these have cut-outs which snap
firmly into the clips so that the radio can be
pulled out. Pull the unit squarely from its
aperture, or it may jam. If the unit proves
difficult to withdraw, remove the cassette tray
(or where applicable, the CD player) frombeneath the unit, then reach through the
aperture and ease it out from behind.
7With the radio partly withdrawn, disconnect
the feed, earth, aerial and speaker leads.
Where applicable, also detach and remove
the plastic support bracket from the rear of
the unit.
Refitting
6Refitting is a reversal of removal. With the
leads reconnected to the rear of the unit,
press it into position until the retaining clips
are felt to engage. Reactivate the unit by
entering the correct code in accordance with
the maker’s instructions.
