195 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 255), 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 parking brake. The automatic trans-
mission fluid must be at normal running
temperature, 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. Used
engine oil is particularly flammable.
 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.

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 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.

197 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.

199 Car care and technical information
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 8996860).
BatteryThe 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.
WARNING
Do not fill the power steering fluid to
above the MAX mark. Too much fluid can
result in leakage.
Power steering fluid on hot engine com-
ponents constitutes a fire risk.
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.

201 Car care and technical information
Charging/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.

216 Car care and technical informationMaxi fusesThe Maxi fuses are housed in the fuse box
under the hood. These fuses can be
checked in the same way as the other fuses.
The Maxi fuses are designed to protect the
car’s electrical system from being dam-
aged. Each Maxi fuse protects a number of
electrical circuits and functions and there-
fore has a higher rating (amperage) than the
standard fuses. No spare Maxi fuses are
supplied with the car.
DICE / TWICEDICE = Dashboard Integrated Central Elec-
tronics
TWICE = Theft-Warning Central Electronics
DICE and TWICE are electronic control
modules that monitor and control a variety
of functions, including:
DICE controls (among other things):
 Front lights and interior lighting.
 Instrument illumination.
 Intermittent wiper operation.
 Electric heating of rear window and door
mirrors.
 Cooling fans.
TWICE controls (among other things):
 Central locking.
 Car alarm (Anti-theft system).
 Engine immobilizer.
 Autochecking of lights.
 Electric heating of rear seat.
 Safety belt reminder.
 Electrically adjustable passenger seat.The DICE and TWICE control modules are
linked to a data bus, which is basically an
information carrier that allows information to
be exchanged between all the control mod-
ules and components connected to the bus.
If a fault occurs in any of these components,
diagnostic faults codes are set in the rele-
vant control module, which facilitates fault
diagnosis at the Saab dealer.
The scan tool connector for fault diagnosis
is located under the instrument panel on the
drivers side.
NOTEIf a Maxi fuse blows, it means that there
is a major fault in the electrical system.
Have the car checked without delay by
an authorized Saab dealer.
