218 Car careChanging bulbs
Auto checking 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 dis-
played on the SID.
Example of SID message:
The following bulbs are not checked: park-
ing 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
SportSedan:
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.
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.

Wrong bulb fitted
If a low 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 274.
Xenon headlights 3Xenon headlights produce roughly two
times as much light as halogen 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 hi gh 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 con-
trol unit by the engine bay fuse box. Head-
light alignment is adjus ted automatically to
the car’s load to prevent dazzling drivers in
oncoming traffic.
If a fault is detected in the system, the fol-
lowing message will be displayed on the
SID:
Right high beam failure.
WARNING
Xenon headlights are high tension. All
work on xenon headlights, including
changing bulbs, must be carried out by
dealer personnel.
Headlight levelling
malfunction.
We recommend you to contact a Saab
dealer to have a xenon headlight changed

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 tr unk. 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 f ilament 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 always con- sult an Saab dealer before modifying
or adding any electrical equipment.
Failure to do so can result in the elec-
trical system being damaged.
 Never replace a fuse with one having a higher rating than specified (see
page 235). 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 con-
tact a Saab dealer.

258 Car careDriving with a compact wheel
fittedObserve the following when the compact
spare tire is fitted:
 The compact spare is light and easy to handle when changing a tire.
 Do not drive further than necessary with the compact spare fitted - the maximum
life of the tire is only just over 2,000 miles
(approx. 3,500 km).
 Refit the standard tire as soon as possi- ble.
 Fitting a spare tire/wheel without pressure sensor will trigger a malfunction
message, see page 255.
Important considerations when driving with
a compact spare tire:
 The car’s ground clearance is reduced.  The car must not be driven with more than
one compact spare tire at a time.
 Avoid driving against the curb.
 Do not use snow chains.
 Do not fit the wheel cover - this would conceal the warning text.
Changing a tire
WARNING
 Do not exceed 50 mph (80 km/h). The
tire can overheat affecting the car’s
road holding.
 Tire pressure: refer to page 291.
 The spare tire or punctured tire must be stowed under the trunk floor, and
secured in place with the retaining nut.
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.

262 Car care
Tire repair kit3
The tire repair kit re places the spare wheel.
The repair kit allows a punctured tire to be
temporarily repaired and reinflated without
needing to remove the wheel.
Minor damage to the tire, such as a foreign
object that has penetrated the tread, can be
temporarily repaired with the repair kit.
Do not remove the foreign object. Damage
larger than 0.16 in. (4 mm) and damage to
the sidewalls cannot be repaired with the
repair kit.
Follow the instructions supplied with the
repair kit carefully.
If the compressor sounds strange or
becomes abnormally hot, leave it switched
off for at least 30 minutes.
WARNING
Make sure no one can jog the gear lever,
for example, as the engine must be idling
when the tire is repaired. There is other-
wise a risk of personal injury.
Do not use the repair kit if:
 the damage to the tire is larger than 0.16 in. (4 mm).
 the wheel is damaged.
Do not exceed 50 mph (80 km/h) after
repairing one of the car tires with the
repair kit.
WARNING
Change the punctured tire as soon as
possible.
Replenish the repair kit at a workshop.
We recommend that you contact an
authorized Saab workshop. The canister
of sealant must be changed once every
four years. See the date on the canister.
The handling characteristics of the car
may be impaired.
Driving with a tire that is underinflated or
has a puncture can damage the tire in
such a way that it is not possible to repair
it with the sealant.

Car care
Prevent the compressor getting wet.
The canister of seal ant can only be used
once. Replace a used canister at a work-
shop. We recommend that you contact an
authorised Saab workshop.
The tire repair kit can be used at tempera-
tures down to –22°F (–30 °C). At low tem-
peratures the sealant is more viscous and
so is less able to seal slightly larger
damage.
If a punctured tire is to be repaired:
 Allow the engine to idle. The compressor will consume some energy.
 Apply the handbrake.
 Turn on the hazard warning light.
 Position the warning triangle to warn other drivers.
The repair kit is stowed under the luggage
compartment floor. 1 Allow the engine to idle.
2 Remove the repair kit from the luggage
compartment. 3 Remove the electric cable and the air
hose from the compartment on the
bottom of the compressor.93_US_7carcare_MY09.fm Page 263 Tuesday, April 15, 2008 11:26 AM
