208 Car careChanging bulbsAutochecking of lightsThe bulbs that are most important from the point of view of traffic
safety are monitored by the car’s electrical system. If one of these
bulbs should fail, a message will be displayed on the SID.
Example of SID message:
The following bulbs are not checked: parking lights, front fog lights,
reversing lights, license plate lighting, side marker lights and side
direction indicators.If a brake light bulb fails
If a brake light bulb fails, the adjacent taillight will act as a brake light
to ensure traffic safety. Change the broken bulb when possible.
All rear light bulbs are of the same type and rated 21 W, with the
exception of the license plate lighting which is rated 5 W.
Wrong bulb fitted
If a dipped or main beam bulb of too high a rating is fitted, a bulb
failure message will be shown on the SID (a too high wattage bulb
can damage the reflector).
If the following message is displayed but the bulb shines, it is most
likely that an incorrect bulb has been fitted.
Note:
When changing bulbs, fit the same type of bulb (e.g. Long-Life)
as that removed.
Headlight aiming, page 257.
WARNING
Before changing a bulb in the engine bay, switch off the engine
to avoid the danger of fingers and hands being injured by moving
parts.
The radiator fan can cut in even when the engine is switched off.NOTICESwitch off the ignition before changing a bulb, to avoid possible
short-circuiting.

257 Car care
Headlight aimingThe vehicle has a visual optical headlight
aiming system equipped with vertical
aiming device. The aim has been preset at
the factory and should normally not need
further adjustments.
If your headlights are damaged in a crash,
the headlight aim may be affected. If you
believe your headlights need to be re-
aimed, we recommend that you take it to
your Saab dealer for service. However, it is
possible for you to re-aim your headlights as
described in the following procedure.To check the aim, the vehicle should be
properly prepared as follows:
 The vehicle shall be placed so that the
headlights are 25 ft (7.6 m) from a light
colored wall or other flat surface. The
aiming area should be darkened, this will
improve your ability to see the beam of the
low beam headlight being aimed.
An optical headlamp aimer can also be
used and will than replace the wall.
 The vehicle must have all four wheels on
a perfectly level surface which is level all
the way to the wall or other flat surface.
 The vehicle should be placed so it is per-
pendicular to the wall or other flat surface.
 The vehicle should be unloaded and fuel
tank full, and one person or 160 lbs.
(75 kg) on the drivers seat.  The vehicle should be fully assembled
and all other work stopped while headlight
aiming is being done.
 The vehicle should not have any snow, ice
or mud attached to it.
 Tires should be inflated to the prescribed
pressure.
 Close all doors.
 Rock the vehicle to stabilize the suspen-
sion.
Headlight aiming is done with the vehicle
low beam lamps. The high beam lamps will
be correctly aimed if the low beam lamps
are aimed properly.
WARNING
Before checking/adjusting the headlight
aiming, switch off the engine to avoid
danger of fingers and hands being injured
by moving parts.
The radiator fan can start up even when
the engine is switched off.NOTICETo make sure that your headlights are
aimed properly read all instructions
before beginning. Failure to follow these
instructions could cause damage to
headlight parts or a not correctly aimed
headlight.

258 Car careIf you find that the headlight needs adjust-
ment follow these steps:
1 Open the hood and locate the vertical
aiming devices there are two vertical
aiming devices which shall be turned
simultaneously and the same amount of
turns.
2 Locate the marker on the lens.
3 Measure the distance from the ground to
the aim marker No.1 on each lens.
Subtract 2 inches.4 At the wall or other flat surface, measure
from the ground to the recorded dis-
tance (see point 4) and draw a horizontal
line the width of the vehicle.1 Wall or garage door.
2 25 ft (7.6 m) between wall and headlight lens.
3 Measurement from the ground to the low beam aiming marker on the headlight lens.
4 Same measurement as (3) but substract 2 inches.

5Cars with Bi-Xenon lights:
Bi-Xenon lights with automatic headlight
levelling system must first do a refer-
ence run before aiming: Start the engine
and let the headlights do a reference
run. Turn off the engine but leave the low
beam on.
Cars with halogen lights:
Turn on the low beam headlights.
Both variants:
Place a piece of cardboard or equivalent
(although not directly on the lens) in front
of the headlight not being aimed. This
should allow the beam cut-off of the
headlight being aimed to be seen on the
flat surface.6 Turn the two vertical aiming screws
simultaneously in the same direction
indicated on the headlight until the hori-
zontal cut-off of the headlight is aligned
with the horizontal line on the wall.
7 If an optical headlight aimer device is
used follow point 1 and 2 and center the
lens of the optical headlight aimer
device at the intersection of the two markers on the headlight lens.
Then follow the instructions in the optical
headlight aimer instruction manual and
point 1, 2, 5, and 6 in this instruction.
NOTICEDo not cover a headlight directly on the
lens to improve beam cut-off when
aiming. Covering a headlight may cause
excessive heat build-up that may cause
damage to the headlight.Correctly adjusted low beam Horizontal line on wall or other flat surface
