2003 SAAB 9-3 fuse

189 Car care
Bi-Xenon headlight, main and dipped beam (certain
variants only)Xenon headlights produce roughly three 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 Bi-Xenon headlights have automatic levelling. The level-
ling system comprises 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
Bi-Xenon headlights are high tension. All work on Bi-Xenon head-
lights, including changing bulbs, must be carried out by dealer
personnel.
Headlight levelling
malfunction.
Contact Saab dealer.

Fuses
The fuses are housed in three fuse panels:
one behind a hatch on the left-hand end of
the fascia, 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 fascia.
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 201). 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.

200 Car careA special tool for removing fuses is provided
on the hatch on the left-hand end of the fas-
cia. Simply push the tool onto the fuse,
squeeze and remove the fuse.
Some fuses and relays may be fitted but not
connected to the car’s electrical system.
MAXI fusesThe car also has a number of large fuses
known as MAXI fuses. These are designed
to protect the car’s electrical system from
being damaged. Each MAXI fuse protects a
number of electrical circuits and functions
and therefore has a higher rating (amper-
age) than the standard fuses. No spare
MAXI fuses are supplied with the car.NOTICEIf a MAXI fuse blows, there is a major fault
in the electrical system. Have the car
checked at a Saab dealer.

224 Car careAir 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 79.
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 185).
d Check the fuses for the ventilation fans
and compressor (see page 201).
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.
