(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,
adding it through the dipstick pipe. The
distance between the MIN and MAX
marks on the dipstick corresponds to a
volume of approximately 0.4 qts
(0.4 litre).
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.
CoolantThe expansion tank is transparent, to facili-
tate checking. The level must be a little
under the mark ”KALT – COLD” on the tank
when the engine is cold. If the SID message
"FILL COOLANT FLUID" is displayed, the
level in the expansion tank should be
checked. Top up as necessary with equal
parts of clean water and coolant. Use only
coolant approved by Saab.
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 filled 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 coolant
approved by Saab can be used for
year-round protection. Change the coolant
as specified in the service program (page
215) and use only coolant approved by
Saab – other makes may need changing
more frequently and may damage the sys-
tem.
NOTEIf there is a burnt smell or the fluid is black,
change the fluid as soon as possible.

Changing the coolant(Usually carried out as part of the Saab
original service by an authorized Saab
dealer)
1 If the engine is hot, loosen the expan-
sion-tank filler cap a little to release the
pressure. Leave the cap in place.
2 Fit a suitable piece of hose onto the
nipple of the drain cock. Let the hose dis-
charge into a receptacle under the radi-
ator and open the drain cock, which is
located on the inside of the radiator
facing the engine bay.
3 Remove the filler cap on the expansion
tank.
4 In a couple of minutes the system will be
empty. Close the drain cock. 5 Mix antifreeze and water in a suitable
container. Use only Saab-approved
coolant.
6 Add the coolant slowly to the expansion
tank. This will take about two minutes,
as the air needs time to escape.
7 Screw the expansion-tank cap on and
run the engine to normal temperature.
Top up with coolant until the level is just
under the "KALT – COLD" mark on the
tank.
8 Check the coolant again after a few days
and top up as necessary.
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.
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.

178 Car careThe charge level should be checked with a
battery-acid tester. The specific gravity of
the acid in a fully charged battery should be
1.28. A specific gravity of 1.18 roughly indi-
cates a 50% charge.
If frequent short journeys are made in cold
weather, the battery 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 drive. A car with standard equipment 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 fitted, such as a mobile
telephone, the time may be reduced to
about 15 days.
Always connect the positive (red) cable to
the positive (+) terminal of the battery and
the negative (blue) cable to its negative (-)
terminal. Always disconnect both battery
leads when boost charging the battery.NOTEA discharged battery can freeze and frac-
ture. Batteries should therefore always be
stored away from frost.
NOTE• Don’t connect the battery terminals
+ and – the wrong way around.
 Serious damage can occur to the car’s
electrical system if a battery or alterna-
tor lead is disconnected while the
engine is running.

Drive beltThe alternator is situated on the right-hand
side of the engine. It is driven via a
poly-V-belt from the crankshaft 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
by an automatic belt tensioner.
See also page 55, "Warning charging".
Wipers and washersWiper bladesCheck 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 this
sometimes leave a wax coating on the wind-
shield.
If wiper performance is still unsatisfactory,
fit new blades.
Windshield and rear window1 Push the catch in (1).
2 Pull the complete wiper blade down-
wards so that it comes away from the
wiper arm. Slide the entire blade out
from the arm.
WARNING
 Keep hands and clothing clear of drive
belts when engine is running.
 Always stop the engine before
inspecting drive belts.NOTESerious damage can occur to the car’s
electrical system if an alternator lead is
disconnected while the engine is running.

188 Car careMAXI 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.
DICE controls, among other things:
 Front lights and interior lighting.
 Instrument illumination.
 Intermittent wiper operation.
 Electric heating of rear window and door
mirrors.
TWICE controls, among other things:
 Central locking.
 Car alarm (Anti-theft system).
 Engine immobilizer.
 Auto checking 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 enhances 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.

208 Car careMaintenance  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
cover the radiator, e.g. with screen netting,
as this will greatly diminish its cooling capac-
ity.
Note: The A/C system will only operate
when the outdoor temperature is above the
freezing point (0°C, 32°F). Switch on the
A/C system when the car stands in a warm
place.
Headlight aimingThe vehicle is equipped with vertical and
horizontal aim indicators. The aim has been
preset at the factory and should normally not
need further adjustments. This is true even
though your vertical and horizontal aim indi-
cators may not fall exactly on the "0" (zero)
marks on their scales.
If your headlight is damaged in an accident,
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: Place the vehicle on a level pad or surface
 The vehicle should be unladen and fuel
tank full, and one person or 160 lbs.
(75 kg) on the drivers seat
 The vehicle should not have any snow, ice
or mud attached to it
 Tires should be inflated to the prescribed
pressure
 Rock the vehicle to stabilize the suspen-
sion
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.
