200 Car careBrake- clutch fluid and
brake padsChecking 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 239.
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 239.
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.

217 Car care
WheelsAlternative 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). Tire pressure
label, see page 253.
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, shock absorbers and wheel
bearings 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 218.
 Wheels larger than 17” 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.
 Wheels smaller than 16” must not be
fitted on 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.

221 Car care
When 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 148.
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.
