58 Instruments and controlsCheck fuse 15 (radiator fan) in the fuse
panel under the hood, see page 220.
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 turbo gauge indicates the air volume for
combustion, which is equivalent to the
engine load.
At low loads, the needle will move within the
white zone. At higher loads and during
heavy acceleration, the needle will enter the
yellow area. At very high loads (certain var-
iants only) the needle may enter the first part
of the red zone without indicating that there
is a fault.Under certain barometric conditions the
needle may enter the first part of the red
zone without necessarily indicating that a
fault has arisen.
If the needle repeatedly enters the red zone
and the engine at the same time loses
power, because the monitoring system is
holding the charging pressure down, you
should contact an authorized Saab dealer.
If the speed exceeds 143 mph (230 km/h),
the increase in speed will be limited by the
lowering of the boost pressure. The pres-
sure gauge then moves towards the middle
of the orange zone, indicating reduced
engine output and thus reduces the speed
of the car as well.
NOTEIf the needle, despite the above action,
enters the red zone, stop the car immedi-
ately, let the engine idle.
If the needle stays in the red zone, stop
the engine.
WARNING
Never open the cap of the expansion tank
completely when the engine is hot, open
with care. The pressure in the cool-
ing-system can cause hot coolant and
steam to be released.

196 Car care and technical informationCoolant The expansion tank is transparent to facili-
tate checking of the coolant level.
When the engine is cold, the coolant must
not lie over the KALT/COLD mark on the
expansion tank.
If the message ”FILL COOLANT FLUID” is
displayed on the SID, check the level of fluid
in the expansion tank.
Top up, as necessary, with equal parts of
clean water and Saab-approved coolant.
If the expansion tank is empty when coolant
is added, run the engine to normal temper-
ature and top up again, as necessary.
Coolant The cooling system is charged at the factory
with coolant containing a 50% concentra-
tion of a combined antifreeze and corrosion
inhibitor. A weaker mixture will result in
reduced anticorrosion protection. For pro-
tection against freezing in very cold
weather, a stronger concentration will be
needed.
A 60% concentration of antifreeze will pro-
vide protection at temperatures down to
-58 F (-50°C).
The coolant does not normally have to be
changed during the service life of the car.
The type of coolant used has a reddish color
and should not be mixed with other types of
coolant. Saab Original coolant should be
used all year round. Only use coolant
approved by Saab.

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.
 Exercise care when adding coolant.
Coolant on hot surfaces constitutes a
fire risk.
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.

204 Car care and technical informationChanging bulbs Check that the new bulb is working when finished.
Some bulbs are of the ”Long-Life” type. Make sure the same type is
fitted when changing one of these.
Headlight aiming, see page 239.
Xenon headlight (certain models only)Xenon headlights produce roughly twice 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 comprises two sensors on the front axle, one on the rear axle
and a control unit under the headlight housing. Headlight alignment
is regulated automatically to prevent dazzling oncoming traffic.
Alignment is also adjusted during braking.
WARNING
Before changing a bulb in the engine bay, 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.
Xenon headlights are high tension and must therefore be
changed at an authorized Saab workshop. Work involving
high-tension components is potentially lethal.NOTE Since the headlight lenses are made of plastic, rinse dried-on
dirt with water and allow it time to soften up before cleaning
the lenses. Avoid rubbing the lenses when dry and never use
solvents.
 Use de-icer spray instead of scraping the ice off.
NOTE Do not fit bulbs with a higher rating than 55 W, since the head-
light reflector and the wiring of the car are not designed for a
higher wattage.
 Switch off the ignition before changing a bulb, to avoid possi-
ble short-circuiting.

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 running, the intake
air is dehumidified, and the resultant con-
densation is drained off through two outlets
underneath the floor of the car in the vicinity
of the front doors. It is therefore perfectly
normal for water to be seen dripping from
these outlets when the car is parked. The
warmer the ambient air and the higher the
humidity, the greater will be the amount of
condensation formed.
Inadequate cooling: a Check that the condenser (forward of
the radiator) has not become clogged
with dirt and insects.
b Make sure that the drive belt for the com-
pressor is not slipping.
c Check the fuses for the ventilation fans
and compressor.
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
screen the radiator, e.g. with netting, as this
will greatly diminish its cooling capacity.Note:
The A/C system will only operate
when the outdoor temperature is above the
freezing point (0°C, 32°F).
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 gas can cause visual impair-
ment or other injury.

239 Car care and technical information
Headlight aimingThe vehicle has a visual optical headlight
aiming system equipped with vertical
aiming device. The aim has been preset at
the factory and should normally not need
further adjustments.
If your headlights are damaged in a crash,
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:
 The vehicle shall be placed so that the
headlights are 25 ft (7.6 m) from a light
colored wall or other flat surface. The
aiming area should be darkened, this will
improve your ability to see the beam of the
low beam headlight being aimed.
 The vehicle must have all four wheels on
a perfectly level surface which is level all
the way to the wall or other flat surface.
 The vehicle should be placed so it is
perpendicular to the wall or other flat
surface.
 The vehicle should be unloaded and fuel
tank full, and one person or 160 lbs.
(75 kg) on the drivers seat.  The vehicle should be fully assembled
and all other work stopped while headlight
aiming is being done.
 The vehicle should not have any snow, ice
or mud attached to it.
 Tires should be inflated to the prescribed
pressure.
 Close all doors.
 Rock the vehicle to stabilize the suspen-
sion.
Headlight aiming is done with the vehicle
low beam lamps. The high beam lamps will
be correctly aimed if the low beam lamps
are aimed properly.
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.NOTETo make sure that your headlights are
aimed properly read all instructions
before beginning. Failure to follow these
instructions could cause damage to
headlight parts or a not correctly aimed
headlight.
