2008 SAAB 9-3 engine

217 Car care
Always connect the positive (red) cable to
the battery’s positive (+) terminal, and the
negative (black) cable to the negative (-)
terminal of the battery. Always disconnect
both battery leads when boost charging the
battery.
A car with standard equipment specifica-
tions and a fully charged battery can be left
for up to 40 days and still have a sufficient
charge for starting. If extra equipment is fit-
ted, such as a mobile phone, the charge
may only be sufficient for about 15 days.NOTEIf boost charging never use anything
but a 12-volt charger, see page 200.
Do not connect the battery termi-
nals, + and –, incorrectly.
Serious damage can occur to the car’s
electrical system if a battery or alterna-
tor lead is disconnected while the
engine is running.
Exercise special care when removing
and fitting the positive (+) cable so as
not to damage the battery disconnect
switch.
Turn the two retainers a quarter turn to
unlock the battery cover.

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.NOTESerious damage can be done to the car’s
electrical system if an alternator lead is
disconnected while the engine is running.

222 Car careWasher jetsThe washer jets, which are adjustable, can
be cleaned with a pin if necessary.
Changing bulbs
Autochecking 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.NOTESwitch off the ignition before changing a
bulb, to avoid possible short-circuiting.
Left low beam failure.

223 Car care
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 275.
Xenon headlights3
33 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 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 con-
trol unit by the engine bay fuse box. Head-
light 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 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

237 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 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 239). 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.

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.
