213 Car care
Changing 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 stop light bulb fails
If a stop light bulb fails, the adjacent taillight will act as a stop 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 258.
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.

214 Car careXenon headlight, dipped beam(certain variants only)
Xenon headlights produce roughly two times as much light as halo-
gen bulbs and have a significantly longer service life.
The lamp units consist of a gas discharge lamp containing xenon.
When the lights are switched on a very high voltage activates the
xenon gas. The lamps soon reach full intensity.
Cars with xenon headlights have automatic levelling. The levelling
system is comprised of two sensors, one on the front suspension
and one on the rear suspension, and a control unit by the engine bay
fuse box. Headlight alignment is adjusted automatically to the car’s
load to prevent dazzling drivers in oncoming traffic.
If a fault is detected in the system, the following message will be dis-
played on the SID:
WARNING
Xenon headlights are high tension. All work on xenon headlights,
including changing bulbs, must be carried out by dealer person-
nel.
Headlight levelling
malfunction.
Contact Saab dealer.

227 Car care
Fuses
The fuses are housed in three fuse panels:
one behind a hatch on the left-hand end of
the dash, one in the engine bay (additional
small unit in front of battery) and one on the
left-hand side of the trunk. There is space
for spare fuses in the hatch on the left-hand
end of the dash.
To check if a fuse has blown, first remove it
from the panel. If the filament is broken, the
fuse has blown.
WARNING
To avoid the risk of short-circuiting and/or
fire breaking out in the electrical system,
the following should be heeded:
 Always consult an Saab dealer before
modifying or adding any electrical
equipment. Failure to do so can result
in the electrical system being
damaged.
 Never replace a fuse with one having
a higher rating than specified (see
page 229). The color of the fuse indi-
cates its amperage.
 If the same fuse blows repeatedly,
have the electrical system checked by
an Saab dealer.
 If a MAXI fuse blows, it means that
there is a major fault in the electrical
system. Have the car checked without
delay by an Saab dealer.

248 Car careChanging a tire
WARNING
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous
without the appropriate safety equipment
and training. The jack provided with your
vehicle is designed only for changing a
flat tire. If it is used for anything else, you
or others could be badly injured or killed if
the vehicle slips off the jack. Use the jack
provided with your vehicle only for chang-
ing a flat tire.
Changing a tire can be dangerous. The
vehicle can slip off the jack and roll over
or fall on you or other people. You and
they could be badly injured or even killed.
Find a level place to change your tire. To
help prevent the vehicle from moving:
1 Set the parking brake firmly.
2 If you have an automatic transmis-
sion, put the shift lever in PARK (P).
For a manual transmission, leave the
car in gear (1st or REVERSE (R)).
3 Turn off the engine and do not restart
while the vehicle is raised.
4 Do not allow passengers to remain in
the vehicle.
To be even more certain the vehicle won't
move, you should put blocks at the front
and rear of the tire farthest away from the
one being changed. That would be the
tire, on the other side, at the opposite end
of the vehicle.
 The car jack is designed solely for use
in changing a tire or fitting snow
chains. It must not be used to
support the car during repair work
or servicing.
Never crawl under a car that is
supported only by a jack. Always use
axle stands.
 Raising your vehicle too high or with
the jack improperly positioned can
damage the vehicle and even make
the vehicle fall. To help avoid personal
injury and vehicle damage, be sure to
fit the jack lift head into the proper
location before raising the vehicle, and
raise the vehicle only far enough off
the ground so there is enough room for
the spare tire to fit (no more than
25 mm or 1 inch clearance between
the ground and the bottom of the tire).
 Switch on the hazard warning lights if
the car is on a road.
 The jack should be stored correctly
under the carpeting in the trunk. If it
lies loose in the car, it could thrown
forward and cause personal injury in
the event of a crash or if the car rolls
over.
 Grit, salt and rust can clog the inner
threads of the wheel bolts if the car has
been driven for several years exclu-
sively with alloy wheels.
If steel wheels are being installed, the
bolt hole threads in the brake hubs
should be cleaned before the thinner
steel wheels are fitted. It may other-
wise not be possible to achieve the
correct clamping force, despite tight-
ening the wheel bolts to the correct
torque.

252 Car carevery warm, dry climates the leather may
need more regular reconditioning. Use con-
ventional leather care products. Follow the
instructions on the packaging.
Do not use unknown harsh polishing
agents, cleaning agents, sprays, coarse
soap or hot water.Textile carpetingTextile carpeting should be vacuum
cleaned regularly. Carpeting can also be
cleaned using a brush or sponge and carpet
shampoo.
For safety reasons, vacuum cleaners that
are not earthed (grounded) must not be
used out of doors.
Engine bayThe engine bay should be cleaned with an
engine decreasing and rinsed with hot
water. The headlights must be covered
over. Do not use a pressure washer. Avoid
spraying electrical components and con-
nectors.
Do not use petrol as a cleaning agent or sol-
vent when carrying out repairs or mainte-
nance. Saab recommends the use of envi-
ronmentally-friendly decrescendos.WashingThe bodywork must be washed frequently.
When the car is new, the body should be
washed by hand using plain cold water and
a clean, soft brush through which the water
flows. Automatic caresses should be
avoided when the car is new.
After 5–6 months the paintwork will have
hardened. To facilitate cleaning, a suitable
detergent can be added to the water, which
should be lukewarm.
Remove any bird droppings without delay,
as these can discolor the paintwork and
prove difficult to polish out. Lay a wad of wet
paper on the patch of dirt and leave it for a
minute or so. It will then be easy to wash off
the dirt.
Use a soft cloth moistened with white spirit
to remove splashes of tar or asphalt. Do not
use strong cleaners, as these can dry out
the paintwork.The underside of the car also needs wash-
ing regularly, and this should be done extra
thoroughly at the end of winter. Clean the
underside of the car by hand if the car is usu-
ally washed in an automatic car wash with-
out special facilities for underbody cleaning.
Never wash or leave the car to dry in the
sun, but wipe it dry with a chamois leather
immediately after washing to avoid smears
and streaks.
Clean the inside of window glass using a
proprietary window cleaner. This is particu-
larly important when the car is new, as
upholstery and trim have a tendency to
sweat a little at first.
Keep the glass well polished, as this helps
to prevent misting.
Clean the outside of the windows with Saab
washer fluid. This is especially important if
the car has been washed in an automatic
car wash, as sometimes a wax treatment is
used that can contaminate the windshield
and impair the performance of the wipers.
NOTICEDo not use alcohol-based cleaners on the
plastic lenses of the front or rear lights, as
these can cause a crackling effect on the
lenses.
The door mirrors should be folded in
before the car enters an automatic car
wash.

257 Car care
Air conditioning (A/C)
TroubleshootingIf a fault occurs in the A/C system, there are
a number of checks you can perform your-
self. If the fault persists, however, have the
system checked at a Saab dealer.
Note:
When the A/C system is running, the intake
air is dehumidified. The resultant condensa-
tion that forms on the evaporator is drained
off under the car. When the car is parked,
this may result in a small puddle forming on
the ground. The warmer the air and the
higher the relative humidity, the more con-
densation will be produced.Inadequate coolinga Check that the controls for temperature
and air distribution are correctly set; see
“Manual climate-control system” on
page 103.
b Check that the condenser (in front of the
radiator) has not become clogged with
dirt and insects.
c Make sure that the compressor drive
belt does not slip (see page 210).
d Check the fuses for the ventilation fans
and compressor (see page 229).
Maintenance The compressor drive belt should be
inspected under the regular service
program.
 Clean away dirt and insects from the
condenser and radiator to prevent clog-
ging. When washing the car, use the hose
to spray the radiator and condenser
(located in front of the radiator) from both
sides (both from the front of the car and
from inside the engine bay). Do not use a
pressure washer.
Caution: Do not hose down the radia-
tor and condenser while the engine is
hot.
Other than in extremely cold weather, do not
screen the radiator, e.g. with netting, as this
will greatly diminish its cooling capacity.
 Applicable to the manual climate control
system - During cold months the air condi-
tioning should be switched on once or
twice a month and run for 5–10 minutes
during highway driving once the engine is
warm.
This action saves the gaskets in the
compressor from being spoiled. The
compressor uses a lubricant that circu-
lates with the coolant.
WARNING
 All repairs and adjustments to the A/C
system must be carried out at a Saab
dealer authorized for this kind of work.
 The A/C system is pressurized. Do not
break any connections or undo A/C
system components.
 Escaping gas can cause eye injury or
other personal injury.NOTICE The A/C system is designed for use
with R134a refrigerant.
 Refrigerant handling requires special
equipment and special procedures for
charging and draining the system.
 Never mix R 134a with other refriger-
ants.
NOTICEDo not use a pressure washer when
cleaning the condenser or radiator due to
the risk of damage.

258 Car careNote:
The A/C system cannot be switched on
when the outside temperature is below 32°F
(0°C). Turn on the A/C system when the car
is standing in a warm place. Simplest is to
always have the A/C button pressed in. The
A/C system will then cut in automatically
when the outside temperature is high
enough.
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.
If you find that the headlight needs adjust-
ment follow these steps:
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.

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
distance (see point 4) and draw a hori-
zontal line the width of the vehicle.
5Cars with xenon lights:
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.1 Wall or garage door.
