229 Car care
Drive beltThe alternator is situated on the right-hand
side of the engine. It is driven by a
poly-V-belt from the crankshaft pulley.A slipping or broken poly-V-belt can
result in:
 no charge to the battery
 no A/C compressor function.
The belt tension is critical and is adjusted
automatically by the belt tensioner.
WARNING
 Keep hands and clothing clear of drive
belts when engine is running.
 Always stop the engine before
inspecting the drive belt.
 The radiator fan is electric and can
start even when the engine is
switched off.NOTICESerious damage can be done to the car’s
electrical system if an alternator lead is
disconnected while the engine is running.

232 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.
SportCombi
The tail lights and brake lights consist of LEDs. If approx. 3/4 of the
LEDs on one side are broken then this is indicated in the SID.If a stop light bulb fails
Sport Sedan: 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 283.
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.
Left low beam failure.
Right high beam failure.

233 Car careXenon headlight, dipped beam3Xenon 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.
We recommend you to contact a Saab
dealer to have a xenon headlight changed

247 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:
 We recommend that you allways
consult an Saab dealer before modify-
ing or adding any electrical equip-
ment. 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 249). The color of the fuse indi-
cates its amperage.
 If the same fuse blows repeatedly,
have the electrical system checked by
a workshop. We recommend that you
contact a 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. We recommend that you
contact a Saab dealer.

273 Car care
Changing 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.

277 Car care
Cleaning and caring for leather
upholsteryThe principal reason for treating leather
upholstery is to maintain its elegant appear-
ance and to provide it with a protective film.
Disco lour at ion caused by dust and wear
mainly affects the lighter shades, although
this is not detrimental to the leather, indeed,
the patina resulting from use is often consid-
ered desirable in leather. But if the leather is
allowed to become too grubby, it can start to
look shabby.
The leather upholstery should be cleaned
and reconditioned twice a year in conjunc-
tion with spring and autumn inspections. In
very 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 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.
