(A/C system)
Fault diagnosis If 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 by an authorized Saab
dealer.Important!
When the A/C system is in operation, mois-
ture from the air will condense on the evap-
orator. When the car is then parked, this
condensation will drip off the evaporator
and form a small pool of water on the
ground. This is normal. The warmer the
ambient air and the higher the humidity, the
greater the amount of condensation formed.Inadequate cooling:
a Make sure that the temperature and
air-distribution controls are in the
appropriate settings, see page 81.
b Check that the condenser (forward of
the radiator) has not become clogged
with dirt and insects.
c Make sure that the drive belt for the com-
pressor is not slipping, see page 203.
d Check the fuses for the ventilation fans
and compressor, see page 214.
NOTE 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.
All repairs and adjustments on the A/C
system must be carried out by a Saab
dealer authorized for this kind of work.
Never mix R134a and R12 refriger-
ants.
WARNING
The A/C system is pressurized. Do not
break any connections or undo A/C
system components.
Escaping refrigerant gas can cause
blindness or other injury.

Maintenance The drive belt for the compressor should
be inspected under the regular service
program.
Clean dirt and insects away from the con-
denser and radiator to prevent clogging.
When washing the car, use the hose to
spray the radiator and condenser (located
forward of the radiator) from both sides
(both from the front of the car and from
inside the engine bay). Do not use a pres-
sure washer.
Caution: Do not use the hose when the
engine is hot.
Other than in extremely cold weather, do not
cover the radiator, e.g. with screen netting,
as this will greatly diminish its cooling capac-
ity.
Note: The A/C system will only operate
when the outdoor temperature is above the
freezing point (0°C, 32°F). Switch on the
A/C system when the car stands in a warm
place.
Headlight aimingThe vehicle is equipped with vertical and
horizontal aim indicators. The aim has been
preset at the factory and should normally not
need further adjustments. This is true even
though your vertical and horizontal aim indi-
cators may not fall exactly on the "0" (zero)
marks on their scales.
If your headlight is damaged in an accident,
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: Place the vehicle on a level pad or surface
The vehicle should be unladen and fuel
tank full, and one person or 160 lbs.
(75 kg) on the drivers seat
The vehicle should not have any snow, ice
or mud attached to it
Tires should be inflated to the prescribed
pressure
Rock the vehicle to stabilize the suspen-
sion
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.
