3To remove the cigarette lighter assembly,
simply pull it from the illumination ring
assembly. If desired, the illumination ring
assembly can be removed, by pulling it from
the housing after depressing the retaining
clips.
Refitting
4Refitting is a reversal of removal.
16Clock - removal and refitting
2
Removal
1Disconnect the battery negative lead.
2Using a thin-bladed screwdriver, carefully
prise the clock from the facia panel.
3Disconnect the wiring plugs and withdraw
the clock (see illustration).
Refitting
4Refitting is a reversal of removal.
17Heated front seats - general
2
Heating pads are fitted to the front seats of
some models. Before attempting to remove a
seat so equipped, disconnect the battery and
the leads from the heating pad.
18Instrument panel -removal
and refitting
3
Removal
1Disconnect the battery negative lead.
2Remove the steering wheel, (Chapter 10).
3Remove the steering column shrouds, and
the instrument panel upper and lower trim
panels, (Chapter 11).
4Remove the single upper, and two lower,
instrument panel securing screws (see
illustration).
5Carefully withdraw the instrument panel,
and disconnect the speedometer cable and
the two wiring plugs. Note that the
speedometer cable is retained by a clip, which
must be pressed towards the speedometer to
release the cable (see illustration).6If desired, the instrument panel can be
dismantled, with reference to Section 19.
Refitting
7Refitting is a reversal of removal, but ensure
that the speedometer cable is not kinked or
twisted between the instrument panel and the
bulkhead as the panel is refitted.

1With the instrument panel removed, as
described in Section 18, continue as follows.
Panel illumination and warning
lamp bulbs
Removal
2Twist the relevant bulbholder clockwise,
and withdraw it from the printed circuit board
on the rear of the instrument panel (see
illustration).
3The bulbs are integral with the bulbholders,
and must be renewed as a unit.
Refitting
4Refitting is a reversal of removal.
Voltage stabiliser
Removal
5Remove the single securing screw from the
rear of the instrument panel, then pull the
voltage stabiliser from the contacts on the
printed circuit board (see illustration).
Refitting
6Refitting is a reversal of removal.
Fuel and temperature gauges -
“low series” models
Removal
7Pull the trip meter reset pin from the front of
the panel.
8Release the two retaining clips at the top of
the panel, and remove the panel shroud (see
illustration).
9Unscrew the two securing nuts, and
withdraw the relevant gauge through the front
of the instrument panel.

27Headlamps -alignment
2
1Correct alignment of the headlamp beams
is most important, not only to ensure good
vision for the driver, but also to protect other
drivers from being dazzled.
2Accurate alignment should be carried out
using optical beam setting equipment.
3In an emergency, adjustments may be
made by turning the adjustment screws
shown (see illustrations). If an adjustment is
made, the alignment should be checked using
beam setting equipment at the earliest
opportunity.
4All 1992-on models are fitted with the
headlamp aim adjustment system, operated
through the facia-mounted switch (see
illustration).
a)Position ‘0’, is for correct alignment if just
the driving seat is occupied.
b)Position ‘1’, if all seats are occupied.
c)Position ‘2’, if all seats occupied and
luggage.
d)Position ‘3’, for just driver and luggage.
28Headlamp dim-dip system -
general, removal and refitting
3
General
1The system (where fitted) is governed by the
dim-dip control unit mounted either behind
and above the glovebox (early models), or
behind the main fuse panel (later models).
2The control unit uses the oil pressure
warning lamp circuit to ensure that, when theengine is running and the sidelamps are
switched on, reduced current is fed to the
headlamp dipped-beam circuits. This lights
the headlamps with approximately one-sixth
of their normal power so that the vehicle
cannot be driven using sidelamps alone.
3To locate the dim-dip control unit, open the
main fuse panel covering flap and unclip it
from its bottom and top mountings (Section 3).
Then use a torch to see whether the unit is
fastened to the plastic bracket behind the facia
and fuse panel. The unit is usually rectangular,
of black plastic, and can be identified by the
colours of the five wires leading to it (see
applicable wiring diagram).
Removal
4If the unit can be seen, remove the driver’s
side lower facia and footwell trim panels
(Chapter 11), then unscrew the four retaining
screws and lower the plastic bracket until the
control unit can be detached.
5If the unit cannot be seen, remove the
glovebox assembly (Chapter 11). The unit will
be fastened to the underside of the facia top
surface.
Refitting
6Refitting is the reverse of the removal
procedure.
26Headlamp aim adjustment
motor - removal and refitting
3
Removal
1Remove the headlamp, (Section 25).
2Twist the motor clockwise to release it from
the headlamp, then carefully disconnect the
motor from the balljoint (see illustrations).
Refitting
3Refitting is a reversal of removal, but ensure
that the motor is correctly engaged with the
balljoint.
