184 Starting and drivingDriving considerations
with compact spare
wheel/tire fitted The following should be observed when the
compact spare wheel (T115/70 R16) is
installed:
The compact spare is light and easy to
handle when changing the wheel. Do not
drive farther than necessary with the com-
pact spare fitted – the maximum life of the
wheel is only just over 2000 miles
(3,500 km). Have the standard wheel
repaired and reinstalled as soon as possi-
ble.Points to bear in mind when driving with a
compact spare wheel:
 The car’s ground clearance is reduced
with the compact spare fitted.
 Only one compact spare wheel may be
used at any time.
 Take care not to hit the curb.
 Do not fit snow chains.
 Leave the wheel cover off, so that the
warning text is readily visible.
For long tripsBefore starting off on a long journey, it is
advisable to have your car inspected by
your Saab dealer.
Obtain a few important items to take along
on your journey such as spare bulbs, wiper
blades, fuses, a Poly-V belt and the like.
You can check some points yourself before-
hand:
 Make sure that the engine is in good con-
dition.
 Check that no oil or fuel leaks out of the
engine or gearbox/transmission.
 Check the coolant and power steering
fluid levels. Check also for leaks.
 Inspect the Poly-V belt and replace it if it
shows any signs of wear.
 Check the battery charge.
 Check the tires for tread pattern and air
pressure, including the compact spare
wheel.
 Take an extra car key/remote control and
keep it separate, see also page 36.
 Check the brakes.
 Check all bulbs.
 Check for the presence of the tool kit and
the jack in the car.
WARNING
Do not exceed 50 mph (80 km/h) as the
tire can overheat and adversely affect the
handling of the car.
The tire should be inflated to 60 psi
(420 kPa).
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 dealer.
A general rule is that all heavy loads must
be well secured in the luggage compart-
ment, see page 142.

Power steeringCheck 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.
Unscrew the cap and wipe the dipstick. To
check the fluid level, first screw the cap on
fully again and then remove. The level
should be between the MAX and MIN marks
on the dipstick when the oil temperature is
about 68°F (+20°C). If the oil is colder the oil
level can be lower, and in higher tempera-
tures the level can be higher, both of which
are acceptable.
Top up with power-steering fluid CHF 11S
(part number 8996860).
Battery
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
 Work on the battery may entail an
explosion hazard, since the battery
gives off hydrogen which forms an
explosive mixture with the oxygen in
the air.
For this reason, always avoid sparks
or open flames when working near the
battery.
 The battery contains corrosive sulphu-
ric 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 the
affected area liberally with water.
If acid gets into the eyes or a large
quantity makes contact with the skin,
seek medical help.

197 Car care
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 61, "Warning charging".
WARNING
 Keep hands and clothing clear of drive
belts when engine is running.
 Always stop the engine before
inspecting drive belts.
 The fan can start even when the
engine is switched off.NOTESerious damage can occur to the car’s
electrical system if an alternator lead is
disconnected while the engine is running.

211 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.
To ensure that the speedometer is as accu-
rate as possible it should be reprogrammed
if wheels of a different dimension are fitted.
Contact an authorized Saab dealer.
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 243.
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 and body mountings 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 212.
 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.

218 Car care
Flat spottingAll tires get hot, especially on long journeys
or when the car is driven hard. After the car
has been parked with hot tires and the tires
have cooled down, a flat spot can form in the
tire, where it is in contact with the ground.
The same can occur if the car has not been
moved for a long time.
Flat spots can cause vibration that can be
felt through the steering wheel, similar to
that experienced when the wheels need bal-
ancing. Flat spots of this type disappear
once the tires get hot again, usually after
10–15 miles (20–25 km) of driving at cruis-
ing speed.
Safety beltsA check should be made periodically to
ensure that the safety belts are working
properly.
 Hold the diagonal strap and pull it sharply.
The safety belt should lock and it should
not be possible to withdraw it further.
A sharp tug on the belt should cause the
inertia reel to lock. Check the floor anchor-
age points for corrosion damage. If a belt is
worn or has any fraying edges, it should be
replaced.
Safety belts must not come into contact with
substances such as polishes, oil or chemi-
cals. If the belts get dirty, wash them with
warm water and a detergent or have them
replaced.
WARNING
Safety belts and belt pretensioners that
were in use in a serious crash must be
replaced even if they are not visibly
damaged.
No attempt must be made to repair, or
modify the function of, safety belts.
