Air filter
Transmission fluidManual transmission
Check and top up the oil in accordance with
the service program.
Automatic transmission
Check and top up the oil in accordance with
the service program.
CoolantThere is an overpressure in the cooling sys-
tem. Coolant temperatures can sometimes
exceed 212° F (100° C).
If the coolant level drops too low, the follow-
ing message appears on the SID:
The properties of the coolant are retained
for the entire service life of the car. There-
fore, it is not necessary to change the cool-
ant.The coolant contains 45 % antifreeze and
anti-corrosion fluid. This ratio gives the best
cooling effect. Lower concentrations should
be avoided, in view of the corrosion risk.
Coolants of a different brand could damage
the engine or cooling system. We therefore
recommend strict use of coolants that have
been 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
To ensure reliable operation, only use
an air filter recommended by Saab
Automobile AB.
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.
Coolant level low.
Refill.
NOTICEIf the cooling system needs topping up,
mix the antifreeze with the appropriate
quantity of drinking water or distilled
water before adding it to the system.
If undiluted 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 ther-
mostat has opened to allow full circula-
tion.

210 Car care4-cyl engine: The expansion tank is trans-
parent to facilitate checking the coolant
level.
When the engine is cold, the coolant shall lie
on or just above the KALT/COLD mark on
the expansion tank (boundary between the
upper and lower sections of the tank, see
illustration).
Top up with a mixture of equal parts of
Saab-approved concentrated coolant and
clean water. We recommend that you con-
tact an authorised Saab workshop.
If the expansion tank is empty when coolant
is added, run the engine until warm so that
the thermostat opens. Top up the tank
again, as necessary.V6 engine: The expansion tank is not trans-
parent. The cap must be unscrewed so that
the coolant level can be checked. When the
cap is screwed off there are two level mark-
ings, HOT and COLD.
When the engine is cold, the coolant shall lie
on or just above the COLD mark in the
expansion tank.

211 Car care
Brake/clutch fluid and
brake padsCheckingBrake fluid should be changed according to
the service program. Refer to the Warranty
and Service Book.
The brake and clutch fluid reservoir is trans-
parent to facilitate checking of the fluid level.
The fluid level should lie between the MAX
and MIN marks.If the level drops too low, the following
message appears on the SID:
Top up as necessary with DOT 4 brake
fluid. Do not use DOT 5 fluid.
Use only new brake fluid from a sealed
container.
The brake fluid level will fall somewhat as
the brake pads wear. The MAX level in the
reservoir corresponds to the amount of
brake fluid required with new brake pads. If
the fall in fluid level is moderate, due to
normal brake pad wear, topping up is not
necessary.
If the brake fluid should require chang-
ing, this must be carried out at a Saab
dealer. We recommend that you contact
a Saab dealer.
The foot brake and parking brake are self-
adjusting.
It is not possible to detect, through abnormal
pedal or parking brake lever travel, whether
the brake pads are worn and need replac-
ing. It is therefore essential that brake pads
be checked regularly, as specified in the
service program.Brake pads should only be changed at a
workshop. We recommend that you con-
tact a Saab dealer.
WARNING
Brake fluid deteriorates as it becomes
old. Because it is hygroscopic, it absorbs
water from the air and, in time, could allow
vapor to form in the brake system, thus
reducing its performance. It is therefore
important that brake fluid be changed
regularly, as specified in the service
program.
Brake fluid level low.
Make a safe stop.
NOTICEAvoid spilling brake fluid onto paintwork,
since it can cause the paint to bubble and
lift. If any brake fluid is spilled, the area
should be flushed with large quantities of
water as quickly as possible.Brake fluid reservoir

212 Car carePower steeringCheck the level of the power steering fluid in
the reservoir regularly, in accordance with
the service program.
The wheels should point directly forwards
during this check.
Clean round the cap before unscrewing it.
Wipe the dipstick. To check the level, screw
down the cap completely and then remove
it again.
The oil level should lie between the MAX
and MIN marks when the oil temperature is
about 68°F (+20°C). If the oil is colder, the
level will be lower, and at a higher tempera-
tures the level will be higher.
Top up with CHF 11S or CHF 202 power
steering fluid.
WARNING
Power steering fluid on hot engine
components constitutes a fire risk.

213 Car care
Battery
Check the charge state and electrolyte level
of the battery regularly.If frequent short journeys are made, the
battery may need extra charging. This can
be done with a battery charger or by taking
the car for a long run.
If the battery is not being charged while the
engine is running, the following message
will appear on the SID:
Check the drive belt (see page 216). If the
belt is damaged, the engine may overheat,
the battery may not be charged and the A/C
compressor may not work.
WARNING
When working on the battery, highly
explosive gas can build up. A spark
could ignite this gas that collects
around the battery.
Therefore, always avoid sparks and
open flames in the vicinity of the
battery.
The battery contains corrosive sulphu-
ric acid. Always wear a face mask or
goggles when working on the battery.
If battery acid gets into the eyes or
splashes onto skin or clothing, wash
the affected area liberally with water.
If acid gets into the eyes or a large
quantity makes contact with the skin,
seek medical help.
Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash your hands after
handling
NOTICEA discharged battery can freeze and frac-
ture. Batteries should therefore always be
stored away from sub-zero temperatures.
Battery not charging.
Make a safe stop.
Checking the battery electrolyte level.
Level correct if level indicator dark.
Battery should be changed if indicator is
light

214 Car careAlways connect the positive (red) cable to
the battery’s positive (+) terminal, and the
negative (black) cable to the negative (-)
terminal of the battery. Always disconnect
both battery leads when boost charging the
battery.
A car with standard equipment specifica-
tions and a fully charged battery can be left
for up to 40 days and still have a sufficient
charge for starting. If extra equipment is fit-
ted, such as a mobile phone, the charge
may only be sufficient for about 15 days.NOTICE If boost charging never use anything
but a 12-volt charger, see page 198.
Do not connect the battery termi-
nals, + and –, incorrectly.
Serious damage can occur to the car’s
electrical system if a battery or alterna-
tor lead is disconnected while the
engine is running.
Exercise special care when removing
and fitting the positive (+) cable so as
not to damage the battery disconnect
switch.
Turn the two retainers a quarter turn to
unlock the battery cover.

215 Car care
Battery disconnect switch3A collision could cause a short circuit in the
alternator or starter motor. A disconnect
switch by the battery’s positive terminal cuts
off the battery from the alternator and starter
motor when the airbags and seatbelt pre-
tensioners are detonated.
WARNING
If the battery disconnect switch has
tripped, do not reset it until you have visu-
ally inspected the car’s electrical system.
If there are visible signs of damage, have
the car checked at a workshop before
resetting the disconnect switch. We
recommend that you contact an author-
ised Saab workshop.NOTICEExercise special care when removing and
fitting the positive (+) cable so as not to
damage the battery disconnect switch.

side of the engine. It is driven by a
poly-V-belt from the crankshaft pulley.A slipping or broken poly-V-belt can
result in:
no charge to the battery
no A/C compressor function.
The belt tension is critical and is adjusted
automatically by the belt tensioner.
WARNING
Keep hands and clothing clear of drive
belts when engine is running.
Always stop the engine before
inspecting the drive belt.
The radiator fan is electric and can
start even when the engine is
