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.
