Aligning right and left asymmetric beams

Headlight beams are normally’adjusted with the help of
special apparatus. If such apparatus is not available, a
marked panel or a wall can be used for the purpose. The
procedure is as follows:

1. Remove the trim frame to expose the adjusting screws
(see illustration). As from model 1973, the trim frame
is provided with holes for the adjusting screws. It is
not necessary to remove the trim frames.

2. Check the tire pressures and place the car, which should
be empty, on a flat surface at a distance of 16’ 6” (5 m)
from the panel.

3. Mark the height of the headlamp center above the
ground on the panel.

4. Switch on the headlights with the beam dimmed and

illustrations. The sloping part of the light-dark dividing
line should lie fully to the right of the mark (to the
left for a left asymmetric beam) and should thus meet
the horizontal part immediately below the dead center.
6. Check the beam of the other light in the same way.

Changing headlight bulbs

Headlight bulbs normally deliver maximum light output
during the first hundred hours of burning. Although they
can last longer, their efficiency deteriorates considerably
after this time. To insure the best possible visibility at

all times, therefore, the headlight bulbs should be changed
about once a year with normal mileage. The halogen
bulbs have almost unchanged light output during the
whole time of burning.

It is also essential that the reflectors are undamaged and
that the wiring terminals make proper contact.

1, Open the hood and remove the contact housing and
rubber sealing cap from the headlight.

2. Push in the bulb retainer and twist it counterclock-
wise; the bulb can then be withdrawn.

3. Fit the new bulb. Do not touch the glass with your
fingers. Make sure that the locating lug is correctly
positioned.

4, Fit the bulb retainer. Make sure that the spring locates
the bulb securely in its correct position.

5. Push on the connector. Install the sealing cap, making
sure that it fits snugly round the bulb retainer and
that the drain hole is at the bottom.

IMPORTANT
If the bulb is wrongly oriented in the reflector, the
throw of the beam will be wrong.

Parking, braking, back-up and direction indicator lights
General

The front parking lights are recessed into the front fenders
and are combined with the direction indicator lights. At
the rear, the tail lights are mounted in a frame together
with the braking, back-up and direction indicator lights.
The braking light is operated by a mechanical contact on
a bracket above the brake pedal.

Changing bulbs — direction indicator, back-up, parking,
braking and number plate lights.

1. Undo the retaining screws and lift off the glass.

Interior lighting
General

The dome light and its switch are mounted on the left
side roof member. It can be switched on by either of the
two door contacts or by the built-in switch.

As from the 1970 model the interior lighting comprises
both a rear light (dome light) complete with switch
mounted on the left doorpost and a forward light
mounted on the rear view mirror.

These lights are operated by the switch on the doorpost
light or by a switch on the gear lever hood.

Changing the bulb, rear light

1. Up to and including model 1971: Insert a screwdriver
under the forward edge of the light fitting and care-
fully prize out the fitting; the bulb can then be re-
moved.

As from model 1972: Undo the two screws; then the
bulb can be removed.

2. Snap in the new bulb, making sure that it is properly
seated in both grips and securely held.

3. Up to and including model 1971: Mount the fitting
by hooking the rear edge into the roof recess and then
pushing home the forward edge.

As from model 1972: Mount the bulb and the two
screws.

To repair or exchange faulty wiring, remove the light

fitting as above.

Changing the bulb, forward light

1. Lift off the transparent plastic glass to expose the

bulb.
2. Change the bulb and press the glass back into place.

Ignition switch and gear indicator illumination on cars
with automatic transmission

General

The light at the ignition switch is switched on by the two
door contacts. As from the 1970 model, it can also be
operated by the switch on the gear lever cover.

Cars with automatic transmission have illuminated gear
selector scales. On the 1970 model, this light is connected
in parallel with the tail light.

As from the 1971 model it is connected to the ignition
terminal 15”.

Trunk illumination

The trunk light, mounted on the front beam in the cen-
ter of the trunk compartment, is switched on and off by
a contact located on the left-hand side above the wheel
housing. The contact is actuated by the left hinge of the
trunk lid.

Saab 99 Combi Coupé:

The trunk light, mounted on the right hand side in the
trunk, is switched on and off by a contact at the rear
door striker. The contact is actuated by the door lock.

llumination of control switches and heater controls, as
from 1971 model

General

The control switches are illuminated by a light bulb lo-
cated between two refractors in the instrument panel
above the switches. The refractors, which are made of
acrylic plastic, have recesses in line with each switch, the
depth of the recess increasing with distance from the
bulb. Light rays striking such a recess.are refracted 90°
to illuminate the switch through a hole in the panel.
The heater controls are illuminated in the same way.

Changing bulbs

The control switch light bulb is located below the speedo-
meter and can be reached after removal of the screen on
the instrument side under the instrument panel. The
heater control light bulb can be reached by removing the
plastic cover inside the glove compartment.

DIRECTION INDICATORS
General

The direction indicators consist of flashing lights at front
and rear. The front ones are combined with the parking
lights and flash with an orange light. The rear direction
indicators have separate bulbs which also flash with an
orange light.

The flasher unit is mounted under the instrument panel
and is combined with a control relay which flashes a green
light on the instrument to indicate that the direction indi-
cators are on and that both front and rear lights are flash-
ing.

If either light is not working, this can be detected by
faiture cf the indicator lamp to flash and by a faster rate
of flashing in the light that is still intact. The rate of flash-
ing is 60—120 per minute when the flasher unit is in nor-
mal condition and bulbs of the right power are installed.
The flasher unit cannot be adjusted. If other components
(switch, wiring and bulbs) are normal, the cause of an ab-
normal flashing rate lies in the flasher unit, which should
then be exchanged.

NOTE
The flasher will work at abnormal speed if bulbs of
the wrong power are fitted.

Self-canceling mechanism of direction indicator control
lever

The play between the actuator and the “tooth” of the
lever should be 0.008—0.024’ (0.2—0.6 mm) when the
lever is in neutral. Adjust the clearance by placing spacer
washers between the lever and its mounting bracket.

NOTE
The actuator must be so placed that its centerline
coincides with the centerline of the control lever
housing when the front wheels are lined up fore-and-
aft.

HORNS AND HORN CONTROLS

General

Up to and including model 1971:

The horns are mounted under the front bumper. They
are of loud-tone type, tuned with a high and low note
respectively.

If the horns give a discordant note, locate the one that
is defective and adjust by turning the contact screw
marked with red paint on the back of the horn until a
pure chord is obtained.

As from model 1972, there is only one horn mounted.
The horn is located on the left reinforcement in the en-
gine compartment.

As from model 1973, the horn is located on the outside
of the left inner bumper bar.

Horn control, model 1969
In the 1969 model the horns are operated by the wind-

shield wiper control lever. To sound the horns, the lever
is pulled towards the steering wheel.

buttons in the steering wheel safety padding.

Removing the horn control

Remove the safety pad with horn contact from the steer-
ing wheel by undoing the four screws, which are accessible
from the underside of the wheel.

1970—1973 models: Then undo the two nuts which hold
the horn contact to the safety pad.

Model 1974: Disconnect the two cable ends to the horn
contact from the back side of the safety pad and remove
the contact from the safety pad.

When removing the slip ring, the steering wheel must first
be removed (see group 6).
