60 Instruments and controlsTemperature gaugeThe temperature gauge shows the temper-
ature of the coolant. The needle should be
in the middle of the scale when the engine
is at normal operating temperature.
If the needle enters the red zone, the
warning light will come on and an alarm
chime will sound. If the needle approaches the red zone,
which can occur in very hot weather or when
the engine is under a heavy load, drive in the
highest gear possible, keep the engine revs
low and avoid shifting down.
Check fuse 3 (radiator fan) in the fuse panel
under the hood, see page 191.
If the needle repeatedly enters the red zone,
stop the car as soon as it is safe to do so and
check the coolant level by looking at the
level visible through the plastic tank - do not
remove the cap.
If the coolant level falls below the MIN mark,
the SID will display the message ”FILL
COOLANT FLUID”.
Pressure gaugeThe pressure gauge indicates the pressure
in the induction manifold. Under low load
and while the engine is braking there will be
vacuum in the induction manifold.The
needle of the pressure gauge will then move
within the white zone. At higher engine
speeds and higher loads, the turbo-com-
pressor produces an overpressure in the
induction manifold. The needle will then
enter the orange zone. Normally the needle
should not enter the red zone, since a mon-
itoring system sets limits to the charging
pressure and protects the engine.
NOTEIf the needle, despite the above action,
enters the red zone, stop the car immedi-
ately.
If the needle stays in the red zone, stop
the engine.
WARNING
Never open the coolant expansion tank
cap when the engine is hot. It contains hot
coolant under pressure. Failure to heed
this warning may result in personal injury.

175 Car care

Changing the coolant(Usually carried out as part of the Saab
original service by an authorized Saab
dealer)
1 If the engine is hot, loosen the expan-
sion-tank filler cap a little to release the
pressure. Leave the cap in place.
2 Fit a suitable piece of hose onto the
nipple of the drain cock. Let the hose dis-
charge into a receptacle under the radi-
ator and open the drain cock, which is
located on the inside of the radiator
facing the engine bay.
3 Remove the filler cap on the expansion
tank.
4 In a couple of minutes the system will be
empty. Close the drain cock. 5 Mix antifreeze and water in a suitable
container. Use only Saab-approved
coolant.
6 Add the coolant slowly to the expansion
tank. This will take about two minutes,
as the air needs time to escape.
7 Screw the expansion-tank cap on and
run the engine to normal temperature.
Top up with coolant until the level is just
under the "KALT – COLD" mark on the
tank.
8 Check the coolant again after a few days
and top up as necessary.
NOTEAlways mix the antifreeze with the
appropriate volume of water before
adding it to the cooling system.
If pure antifreeze is added, the engine
could still freeze and be damaged. This is
because the antifreeze will not mix
properly with the coolant before the
thermostat has opened to allow full
circulation.
WARNING
 Proceed with caution if the radiator is
boiling when you open the hood.
Never remove the expansion-tank
filler cap when the radiator is boiling.
Loosen the cap carefully, and let the
engine cool before removing the cap.
 The cooling system is pressurized –
hot coolant and vapor can escape
when the filler cap is released.

Air conditioning
(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 77.
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 179.
d Check the fuses for the ventilation fans
and compressor, see page 189.
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.

208 Car careMaintenance  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.
