62 Instruments and controls Check fuse 1 (radiator fan) in the fuse panel
under the hood, see page 231.
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 Saab Information Display (SID) will dis-
play the message ”Coolant level low.
Refill.”.
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 or under cer-
tain barometric conditions, the needle may
enter the first part of the red zone without
indicating that there is a fault.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 149 mph/240 km/h
(155 mph/250 km/h, 9-5 Aero) the increase
in speed will be limited by the lowering of the
boost pressure. The pressure gauge then
moves towards the middle of the orange
zone, indicating reduced engine output and
thus reduces the speed of the car as well.
NOTICEIf 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. Failure to heed this
warning may result in personal injury.

207 Car care and technical information
Coolant 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 ”Coolant level low. Refill.” 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 45 % 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. Note:
If incorrect coolant is used or added, the
life-time properties will be affected. Even if
the coolant is flushed from the system and
replaced with life-time coolant, life-time
properties are no longer retained and the
coolant must then be drained and replaced
at regular intervals.

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.
 The cooling system is pressurized –
hot coolant and vapor can escape
when the filler cap is released. These
can cause injury to your eyes and
burns. Loosen the cap carefully, and
let the engine cool before removing
the cap.
 Exercise care when adding coolant.
Coolant on hot surfaces constitutes a
fire risk.
NOTICEAlways 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.

212 Car care and technical informationDrive belts
The alternator is situated on the right-hand
side of the engine, adjacent to the bulkhead.
It is driven via a Poly-V-belt from the crank-
shaft pulley.
The Poly-V-belt also drives the water pump,
the A/C compressor and the steering servo
pump.
The belt tension is critical and is adjusted
automatically by the belt tensioner.
See also page 55, ”Warning, charging”.
WARNING
 Keep hands and clothing clear of drive
belts when engine is running.
 Always stop the engine before
inspecting drive belt.
 The radiator fan is electric and can
start even when the engine is
switched off.NOTICESerious damage can be done to the car’s
electrical system if an alternator lead is
disconnected while the engine is running.

215 Car care and technical information
Changing bulbsCheck that the new bulb is working when finished.
Use only "Long Life" bulbs.
Headlight aiming, see page 259.
Xenon headlight (certain variants)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 voltage and must therefore be
changed at an authorized Saab workshop. Work involving
high-voltage components is potentially lethal.NOTICE 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.
NOTICE 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.
 Do not touch the glass of the bulbs with your fingers. The oil
on your skin can shorten the life of the bulb.

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).
WARNING
 All repairs and adjustments on the A/C
system must be carried out by 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 refrigerant gas can cause
visual impairment or other 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 R134a and R12 refriger-
ants.
