171 Car care and technical information
Engine oilChecking the oil level Check the engine-oil level regularly. This
should be done after the engine has been
run to normal temperature and then allowed
to cool for 2–5 minutes, with the car stand-
ing on level ground. Remove the dipstick
and wipe it clean before checking the level.
4-cylinder engine The oil level must not be allowed to drop
below the MIN mark on the dipstick, nor
should oil be filled beyond the MAX mark, as
this can lead to excessive oil consumption.
The distance between the MIN and MAX
marks on the dipstick corresponds to a
volume of approximately 1.05 qts (1 liter).
When necessary, add oil of the recom-
mended grade via the dipstick tube.
V6 engine The oil level must not be allowed to drop
below the MIN mark on the dipstick, nor
should oil be filled beyond the MAX mark, as
this can lead to excessive oil consumption.
The distance between the MIN and MAX
marks on the dipstick corresponds to a
volume of approximately 1.05 qts (1 liter).
Top up, as necessary, with oil of the recom-
mended grade.

172 Car care and technical informationOil changingThe engine oil must be changed in accor-
dance with the service program, see page
218.
Oil volume and grade, see page 229.
Oil changing should be carried out on a
warm engine. Unscrew the drain plug in the
bottom of the sump and leave the oil to drain
into an oil tray or other suitable receptacle
for at least ten minutes. Take care, as the oil
may be hot.
After the oil has been drained, unscrew and
remove the oil filter. Fit a new filter and
tighten it by hand before adding new oil.
Refit the drain plug with a new washer.
Run the engine to normal temperature and
check the oil level.
NOTEChange of engine oil and oil filter may be
required more frequently (5000-mile
intervals (8,000 km)) if any one of the fol-
lowing conditions apply to the car:
 Most trips are less than 5 to 10 miles (8
to 16 km). This is particularly important
when outside temperatures are below
freezing.
 Most trips include extensive idling
(such as frequent stop-and-go driving).
 Most trips are through dusty areas.
 You frequently tow a trailer or use a car-
rier on top of your vehicle.
 If the vehicle is used for delivery ser-
vice, police, taxi or other commercial
applications.

173 Car care and technical information
Transmission fluidManual transmission Check and top up the fluid in accordance
with the service program.
If original fluid cannot can be obtained for
topping up (see page 231), automatic trans-
mission fluid Dexron III (synthetic fluid) can
be used. If so, the car should be taken to an
authorized Saab dealer as soon as possible
to have the reason for low fluid level cor-
rected and original fluid installed.Automatic transmission Check the fluid level as follows:
1 Stand the car on level ground and apply
the handbrake. The automatic transmis-
sion fluid must be at normal running tem-
perature, approximately 175°F (80°C).
This can be achieved by driving the car
for about 30 min on the open road.
2 With the engine idling, move the selector
lever to D and wait for at least
15 seconds. Next, move the selector
lever to R and wait for 15 seconds again.
Finally, move the selector lever to P. Let
the engine idle.
3 Wipe the dipstick clean with a lint-free
cloth and put it back.
4 With the fluid at normal temperature, the
level should be between the MAX and
MIN marks on the dipstick. Top up, as
necessary, with Texaco Texamatic
Dexron III automatic transmission fluid
(mineral oil-based), adding it through
the dipstick pipe. The distance between the MIN and MAX marks on the dipstick
corresponds to a volume of approxi-
mately 0.4 qts (0.4 liter).
If the outside temperature is below 50°F
(10°C), the fluid will not reach the specified
temperature of 175°F (80°C). In this case,
the correct fluid level may be 0.8 in (20 mm)
below the MAX mark.
WARNING
 Prolonged and repeated exposure of
the skin to engine oil can cause seri-
ous skin disorders.
 Avoid prolonged skin contact when-
ever possible. Wash the affected area
thoroughly with soap and water after
any contact.
 Keep oil out of reach of children.
 Do not touch the turbocharger or
manifold. These get very hot when the
engine has been running.
 Do not spill oil on hot parts of the
engine as this could cause a fire.
 Protect the environment. Do not dis-
pose of oil in the ground or down a
drain. Dispose of all used oil and oil fil-
ters at an appropriate disposal facility.
NOTEIf there is a smell of burning fluid or the
fluid is black, change the fluid.

174 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 corrosion-inhibiting properties of the
coolant deteriorate over time, but
Saab-approved coolant can be used for
year-round protection. Change the coolant
as specified in the service program and use
only Saab-approved coolant – other makes
may need changing more frequently and
may damage the system.

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.
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.

175 Car care and technical information
Changing the coolant (Usually carried out as part of the Saab orig-
inal service by an authorized Saab dealer)
1 If the engine is hot, open the expan-
sion-tank filler cap carefully to release
the pressure, but do not remove it com-
pletely. Place a suitable receptacle
under the radiator and undo the drain-
cock.
2 Remove the filler cap on the expansion
tank.
3 The system takes about two minutes to
drain. Close the draincock.
4 Mix the antifreeze and water to the
required strength in a suitable container.
Use only Saab-approved coolant.
5 Add the coolant slowly to the expansion
tank. This will take about two minutes,
as the air needs time to escape.
6 Screw on the filler cap and fully tighten
the drain cook. Run the engine to normal
temperature. Top up the coolant, as nec-
essary, until the level is just below the
MAX mark on the tank.
7 Check the coolant again after a few days
and top up as necessary.
Brake and clutch fluid Checking the fluid level The combined brake and clutch-fluid reser-
voir is transparent to facilitate checking of
the fluid level.
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 reg-
ularly, as specified in the service pro-
gram.

176 Car care and technical informationThe level should be between the MAX and
MIN marks. Top up, as necessary, with
DOT 4 fluid. Do
not
use DOT 5 brake fluid.
Use only new brake fluid from a sealed con-
tainer.
Check that there are no leaks in the brake
system.
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.
Changing of the brake fluid should be
carried out by an authorized Saab dealer.
The vehicle´s regular braking system is
adjusted automatically, but the parking
brake has to be adjusted manually. This
work, involving adjustment of the parking
brake cables and brake pads, must only be
carried out by an authorized Saab dealer.
It is not possible to detect, through abnormal
pedal or parking brake-lever travel, whether
brake pads are worn and need replacing. It
is therefore essential that brake pads be
checked regularly, as specified in the ser-
vice program.
Brake pad wear indicators The outboard brake pads on the front
wheels incorporate pad-wear indicators.
When the lining is down to 0.11 in (3 mm),
the pad will produce a screeching, squeal-
ing or scraping noise when the brakes are
applied. New pads should be fitted without
delay.
Brake pads should only be changed by
an authorized Saab dealer. To ensure
optimum brake performance, use only
Saab original brake pads.
Power steering fluidCheck the level of the power steering fluid in
the reservoir regularly, in accordance with
the service program.
The wheels should point forward during the
check.
Clean around the cap before it is
unscrewed. Clean the dipstick. Screw in the
cap completely again before checking the
level.
The oil should lie between the MAX and MIN
marks when the oil temperature is about
70°F (+20°C). If the oil is colder the level can
be lower, and in higher temperatures the
level can be higher, both of which are
acceptable.
Top up with ”Power Steering Fluid
CHF 11S” (part number 3032380).

177 Car care and technical information
Battery
The battery is provided with a cover to pro-
tect it from radiated heat. If the battery is
exposed to high temperatures, its life will be
shortened. To remove the cover, pry out the
edge a little, located at the rear of the cover.
The cover fits the standard battery installed
in the car. If a new battery is to be fitted,
make sure that its dimensions are the same
as the standard one.
The fluid level and the charge level should
be checked regularly.
The best way to check the charge is to use
a hydrometer.
Tap water contains salts and minerals that
accelerate the corrosion of the battery elec-
trodes, which can shorten the life of the bat-
tery.
The specific gravity of the electrolyte when
the battery is fully charged is 1.28. A specific
gravity of 1.18 roughly indicates a 50%
charge (see also page 230). If frequent short journeys are made, the bat-
tery may need to be given a booster charge.
This can be done either using a battery
charger or by taking the car for a long run.
A car with a standard equipment specifica-
tion 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 car phone, the charge may
only be sufficient for about 15 days.
WARNING
 The battery emits hydrogen which,
when mixed with the oxygen in the air,
forms a highly explosive gas. Avoid
causing sparks and keep open flames
well away from the vicinity of the bat-
tery.
 The battery contains corrosive sulfuric
acid. Always wear a face mask or
goggles when working on the battery.
 If battery acid gets into the eyes or
splashes the skin or clothing, wash
affected area liberally with water.
If acid gets into the eyes or a large
quantity makes contact with the skin,
seek medical help.
NOTENever use tap water to top up the battery.NOTEA discharged battery can freeze and frac-
ture. Batteries should therefore always be
stored away from frost.

178 Car care and technical informationCharging/replacing the batteryConnect the positive lead to the positive (+)
battery terminal (red), and the negative lead
to a good ground point, e.g. the lifting lug at
the front of the engine.
To remove the battery, always disconnect
the negative (black) lead first and reconnect
it last when fitting the new battery.
The battery size must comply with DIN
53735 MFI 230/2.16. NOTETo avert the danger of short-circuiting
between the positive (+) terminal on the
battery and the inlet manifold on the
engine, always disconnect the negative
(-) battery lead first and reconnect it last.NOTE Never reverse the polarity of the bat-
tery by connecting the leads to the
wrong terminals. The red, positive
lead connects to the positive (+) termi-
nal, and the black, negative lead to the
negative (-) terminal.
 Serious damage can be done to the
car’s electrical system if a battery or
alternator lead is disconnected while
the engine is running.
 The nut on the battery clamp should
be tightened to a torque of 10 Nm.

Drive belts The alternator is situated on the right-hand
side of the engine, adjacent to the bulkhead.
It is driven via a Poly-Vee-belt from the
crankshaft pulley.
The Poly-Vee-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 47, ”Warning, charging”.
WARNING
 Keep hands and clothing well clear of
drive belts when engine is running.
 Always stop engine before inspecting
drive belts.NOTESerious damage can be done to the car’s
electrical system if an alternator lead is
disconnected while the engine is running.

180 Car care and technical informationWipers and washersCheck and clean all wiper blades regularly.
We recommend Saab washer fluid for
cleaning.
If poor wiper performance is experienced,
clean the windshield with Saab washer fluid.
This is particularly important if the car has
been through an automatic car wash, as
these sometimes leave a wax coating on the
windshield.
If wiper performance is still unsatisfactory,
fit new blades.
Changing the windshield wiper
bladesLift the wiper arm off the windshield
1 Depress the catch.
2 Pull the complete blade assembly down
to free it from the wiper arm, and then lift
it off the arm.
Changing headlamp-wiper blades 1 Lift the wiper arm off the headlamp.
2 Release the wiper blade by pulling it
straight down, at right angles to the
wiper arm.
To fit the new blade, slot the blade into the
retainer on the wiper arm, and press it firmly
home.
