General
1 When renewing bulbs, note the following
points:
a) To eliminate the risk of causing accidental
short-circuits, disconnect the battery
6.39b Removing the lens
negative cable, and position it away from
the terminal.
b) When fitting a new bulb, avoid touching
the glass lens - hold it by the metal flange,
as deposits left by hand contact can
shorten the bulb's service life.
c) Only fit new bulbs of the correct power
rating (refer to the Specifications).
d) Before fitting a new bulb, first check the
condition of the contacts in the bulbholder.
Ensure that there is no corrosion or dirt
that may cause a poor connect/on.
e) The Saab 9000 bulb filament monitoring
system uses a balanced relay to detect
bulb failure. It has been suggested that all
bulbs (except headlamps) should be
replaced in pairs, otherwise the monitoring
systems may pick up the imbalance of
current and indicate a bulbs has failed.
Headlight bulb
General
2 On earlier models, the main and dipped beam
filaments for each headlight are contained in one
bulb, at the centre of a single reflector.
3 Later models are fitted with dual-reflector
headlight units, utilising separate bulbs for
main and dipped beam.
Models with single-reflector headlights

General
13 On earlier models, the parking light is part
of the front light cluster, below the direction
indicator light.
14 On later models, the parking light is
integrated in the headlight unit, and shares the
same reflector as the dipped beam bulb.
7.24 On later models, prise open the cut-
out panel in the loadspace trim to gain
access to the rear of the light cluster
Models with single-reflector

side of the bulbholder, and rotate it anti-
clockwise through a quarter of a turn. Pull the
bulbholder out of the light unit, then pull the
bulb out of the holder (see illustration).

Accurate adjustment of the headlight beam
is only possible using optical beam-setting
equipment, and this work should therefore be
carried out by a Saab dealer or suitably-
equipped workshop.
Certain models have a headlight beam
adjustment control, which allows the aim of
the headlights to be adjusted to compensate
for variation in the vehicle's payload. The aim
is altered by means of facia-mounted switch,
which controls electric adjuster motors
located in the rear of the headlight assemblies.
The switch should be positioned as follows,
according to the load being carried in the
vehicle:
Switch
position Vehicle load
0 Up to 3 occupants (no more than
one in the rear seat), no luggage.
1 Up to 3 occupants in rear seats,
up to 30 kg in luggage.
2 Up to 3 occupants in rear seats,
up to 90 kg in luggage.
3 Up to 3 occupants in rear seats,
luggage area full -
OR up to 5 occupants, luggage
area full, towing caravan/trailer.
7.34 The bulbs are a push fit in the holder
General
1 The instrument panel is a single module,
housing the speedometer, tachometer,
gauges and warning lights, and EDU display.
2 The top panel of the facia can be removed,
allowing access to the instrument panel
without the need to remove the entire facia
assembly.
Removal
3 Disconnect the battery negative cable, and
position it away from the terminal.
4 Refer to the relevant paragraphs of Chap-
ter 11, Section 27 and remove the panel from
the top of the facia.
5 With reference to Chapter 3, remove the air
ducting from above the instrument panel.
6 At the rear of the instrument panel,
disconnect all the multi-plug cable
connectors, labelling them to aid refitting later.
7 Where applicable, disconnect the
speedometer drive cable from the rear of the
instrument panel.
8 On turbocharged vehicles, unplug the boost
gauge hose from the rear of the instrument
panel.
9 Remove the two retaining screws from the
top corners of the instrument panel. Note that
the screw heads face the bulkhead, and so
must be extracted from within the facia, using
a short-handled screwdriver. Recover the
rubber mounting bushes.
10 Lift the instrument panel out through the
top of the facia, and recover the rubber
mounting feet
11 Refer to Section 5 for guidance in
renewing the instrument panel illumination and
warning panel bulbs.
12 The instrument panel is modular in design,
and as such, it is possible to renew individual
gauges by simply removing the retaining
screws and lifting the required gauge out.
Refitting
13 Refit the instrument panel by reversing the
7.36 Removing the rear number plate light
bulb
removal procedure, noting the following
points:
a) As the instrument panel is lowered into
position, ensure that the rubber mounting
feet locate in the indentations on the metal
mounting brackets (see illustration)
b) Ensure that the multi-plug cable
connectors are refitted according to the
notes made during removal, and that they
are firmly plugged in.
c) Make reference to the relevant paragraphs
of Chapter 11, Section 27 when fitting the
top panel of the facia; ensure that all
retaining screws are correctly refitted.
General
1 The clock/trip computer module varies in
function and appearance according to the
specification of the vehicle, but the module
housing (and hence the removal procedure)
remains the same.
2 The top panel of the facia can be removed,
allowing access to the module without the
need to remove the entire facia assembly.
3 The EDU display panel is an integral part of
the instrument panel, refer to Section 9 for
details of its removal.
9.13 As the instrument panel is lowered
into position, ensure that the rubber
mounting feet locate in the indentations on
the metal mounting brackets (arrowed)
