Transmission fluidManual transmissionCheck and top up the fluid in accordance
with the service program.
If original fluid cannot be obtained for top-
ping up, Dexron III (synthetic fluid) auto-
matic transmission 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 corrected and orig-
inal fluid installed.Automatic transmissionCheck the fluid level as follows:
1 Park the car on level ground and apply
the parking brake. The automatic trans-
mission fluid must be at normal running
temperature, approximately 175°F
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 frequenty 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 commerical
applications.
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.

176 Car careBrake- clutch fluid and
brake pads
Checking the fluid level The combined brake and clutch-fluid reser-
voir is transparent to facilitate checking of
the fluid level.
The 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.
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, see page 215.
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 installed with-
out delay.
Brake pads should only be changed by
an authorized Saab dealer. To ensure
optimum brake performance, use only
Saab original brake pads.
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, see page 215.
NOTEAvoid 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.

180 Car careHeadlight wipers 1 Lift the wiper arm off the headlight.
2 Detach the wiper blade by pulling it
laterally from the wiper arm.
3 Fit the new blade by sliding it into the
retainer on the wiper arm and pressing it
firmly home.
WasherThe reservoir holds 5 quarts (4.7 litres).
When the SID message "WASHER FLUID
LEVEL LOW" appears there is about
1.5 quarter (1.4 litres) left.
Fill with quality washer fluid, available from
your Saab dealer and follow the instructions
on the package to reduce the risk of freez-
ing.
If the reservoir is run dry and the car has a
rear-window wiper, then after refilling you
cannot wash the rear window until you have
first washed the windscreen.
Washer jetsThe washer jets, which are adjustable, can
be cleaned with a pin if necessary.
The jet for rear-window washing is located
in the right-hand part of the high-mounted
brake light.

192 Car careWheelsAlternative wheels and tiresIf you wish to fit other tires or wheels than
those supplied with the car, consult your
Saab dealer first as to the possibilities avail-
able.
Wheels/tires combinations that are not
approved by Saab can negatively affect the
car´s directional stability, steering and brak-
ing in both wet and dry conditions.
Do not assume that a wheel/tire combina-
tion will function properly just because it will
bolt on.
The wheels and tires have been carefully
matched to the characteristics of the car and
play a key role in its outstanding roadhold-
ing and handling.
Tire pressureTires need to be inflated to suit the load car-
ried and the maximum speed the car will be
driven (see the recommended tire pres-
sures on the back cover). Note that all
values apply to cold tires. For tires with an
aspect ratio less than /60, increase the tire
pressure by 3 psi (20 kPa) for rough roads
with potholes to minimize the risk of rim
damage.
Never reduce the pressure of a hot tire. If the
tires are hot when you check them, only
increase the pressure, if necessary.
Soft tires will cause faster wear than
over-pressurized tires. They also increase
fuel consumption.
If a valve is leaking, simply unscrew it and fit
a new one.
Important! Remember to adjust the tire
pressures if you change the load in the car
or intend to cruise at a substantially higher
or lower speed than normal.
NOTEFor wide wheels and/or low-profile tires,
bear in mind the following:
Tires and wheels can be damaged in
potholes etc.
Springs and shock absorbers can be
overloaded.
The wheels can come into contact with
chassis and body components.
The speed and load limits for the tires
must not be exceeded; see page 193.
Wheels larger than 16” must not be
fitted on the Saab 9-3. For Viggen
models the wheel should not be larger
than 17”. The maximum permissible
offset for the 9-3 is 49 mm and for the
Viggen 42 mm.
When fitting wheels on a 9-3, please
note that a 15” wheel should be used
on 9-3 Coupé and 5-door models, and
nothing smaller than 16” wheel should
be used for Viggen models. Fitting a
smaller size wheel on a Viggen is not
possible due to the size of the brake
discs.
NOTECheck the tire pressures at least once
per month.
Underinflation is the main cause of:
Tires wearing out prematurely.
Damage to the sidewalls.
Damage to the wheels.

196 Car careWhen changing a wheel, take the tool kit out
first, then the spare wheel.
Changing a wheel
If light-alloy wheels have been fitted to the
car for several years and a change is made
to steel wheels, the threads for the wheel
bolts in the brake discs should be cleaned
before the thinner steel wheels are fitted.
The innermost threads in the holes may be
clogged with sand, salt and rust so that the
correct tightening torque cannot be
achieved.
NOTETo avoid damaging a punctured alloy
wheel this can be placed outside up in the
spare-wheel well but only while driving to
the closest workshop.
A general rule is that all heavy loads must
be well secured in the luggage compart-
ment, see page 129.
WARNING
The car jack is designed solely for use
in changing a wheel or fitting snow
chains. It must not be used to support
the car during repair work or servicing.
Never crawl under a car that is
supported only by a jack.
Special care must be taken if the car is
on a slope – use wheel chocks!
Position chocks, one ahead and one
behind, the wheel that is diagonally
opposite to the one to be changed.
Switch on the hazard warning lights if
the car is on a road.
Apply the parking brake and leave the
car in gear (1st or reverse). Automatic
transmission: move selector to the
P position.
Ensure that everybody is out of the car
before jacking it up.
Never start the engine while the car is
jacked up.
The jack must stand on a firm, level
surface.
Stow the jack in the place provided for
it under the panel in the floor of the
trunk. Secure it properly to avoid injury
to passengers in the event of an acci-
dent.
Do not use the jack for any purpose
other than for jacking up the car.

197 Car care
When it is time to raise the car, apply the
jack to one of the four jacking points (front or
rear) located beneath the sills.
If a floor jack is used it can be applied to the
standard jacking points used by the dealer
or centrally under the front of the engine
subframe. If the car is equipped with a trailer
hitch, the jack can also be placed under the
hitch. 1 Put the car in 1st gear (automatic trans-
mission: move selector to the P position)
and apply the parking brake.
Saab 9-3 Viggen: The front and rear
jacking points are located behind covers
that must be removed.
2 Wind the jack up to a suitable height
before placing it under the recess in the
sill.
3 Make sure that the jack fully engages
the recess in the sill and that the base of
the jack is steady and flat on the ground.
4 Turn the jack handle clockwise until it
just begins to lift the car. 5 Remove the wheel cover (where appli-
cable). Loosen the wheel bolts by half a
turn.
6 Turn the jack handle to raise the wheel
clear of the ground. Remove the wheel
bolts and lift off the wheel.
7 Fit the wheel and screw in the bolts in the
sequence shown (opposite pairs).
Tighten the studs enough for the studs
and wheel to be seated correctly.
See page 199 for sequence.NOTEDo not position the jack under the rear
axle or under the rear floor.

198 Car care8 Lower the car and tighten the wheel
bolts to the correct torque in the
sequence shown (opposite pairs).
Tightening torque:
Light-alloy wheels: 80 ft.lbs (110 Nm).
Steel wheels: 80 ft.lbs (110 Nm).
Do not overtighten the bolts using an
impact wrench: not only can this
damage the wheels but it can also make
it impossible to undo the bolts using the
wheel wrench in the car’s toolkit.9 Recheck the wheel bolts after a few
miles.
Tightening torque:
Light-alloy wheels: 80 ft.lbs (110 Nm)
Steel wheels: 80 ft.lbs (110 Nm)
We advise against using wheels with open
wheel covers in winter, as the brake compo-
nents are then more exposed both to slush
and to road salt and grit.
Tire chains; see page 155.
NOTE
When refitting wheel covers (where
applicable), make sure that the valve
protrudes through the hole in the wheel
cover.
NOTESaab 9-3 Viggen: The minimum permis-
sible wheel diameter is 16”, due to the
size of the brake discs.
