2001 SAAB 9-3 steering wheel

171 Starting and driving
ABS brakes ABS (Antilock Braking System) modulates
the brake pressure to the respective
wheels. Wheel sensors detect if a wheel is
about to lock, and the control module
reduces the pressure to that wheel and then
increases it once more until the tendency is
detected again.
The brake system is equipped with an Elec-
tronic Brake-force Distribution device
(EBD), which distributes the brake pressure
between the front and rear wheels in such a
way as to achieve optimum braking perfor-
mance regardless of the car’s speed and
load.
The ABS system has a built-in diagnostic
function which will switch on the ABS warn-
ing light if a fault is detected in the system
(see page 62). The ABS system will not reduce the braking
distance on loose gravel or on snow or ice
but, because the wheels cannot lock up,
some steering control is retained.
When the ABS system is working, i.e. mod-
ulation of the brake pressure is in progress,
the brake pedal will pulsate and a ticking
noise will be heard. All this is perfectly nor-
mal.
Press the pedal down hard (you cannot
press too hard) and steer the car to safety. Do not release the brake pedal before the
car has come to a halt or the danger is
past!
This is critical.
If the road is slippery, the ABS system will
operate even when only light pressure is
applied to the pedal. This means that you
can brake gently to test the condition of the
road and adapt your driving accordingly.
It is well worth practising the use of ABS
brakes on a skid pad or other suitable facil-
ity.
WARNING
 The additional safety afforded by the
ABS system is not designed to allow
drivers to drive faster but to make
normal driving safer.
 To stop as quickly as possible, without
loss of directional stability, whether
the road surface is dry, wet or slippery,
press the brake pedal down hard
without letting up (do not pump the
pedal), declutching simulta-
neously, and steer the car to safety.

184 Starting and drivingDriving with a loadThe driving characteristics of the car are
affected by the way it is loaded.
 Place heavy loads as far forward and as
low as possible in the trunk.
 Secure the load to the tie downs, see
page 148.
 The load should be such that the car´s
total weight or axle weight are not
exceeded, see page 245.
 Heavy loads mean that the car’s center of
gravity is further back. As a result, the car
will sway more during evasive steering.
 Never exceed the permissible load in the
roof box, even if there is room for more.
 Ensure that the tire pressure is correct –
slight overinflation is preferable to under-
inflation.
 The braking distance of a loaded car is
always greater. Keep your distance from
the vehicle in front.
Tire pressure, see page 217 and back
cover.
TiresThe tire pressure should match the current
load and speed of the car; see the back
cover or the tire pressure label on
page 253.
The tire pressures given apply to cold tires,
that is tires that are the same temperature
as the outside air temperature.
The tire pressure increases as the tires
become warm (e.g. during highway driving)
with approximately 0.3 bar (4 psi). When
the temperature of the tires changes by 50°
(10°C), the tire pressure will change 0.1 bar
(2 psi).Never reduce the pressure of a hot tire. If the
tires are hot when you check them, only
increase the pressure, if necessary.
Underinflated tires wear more quickly than
slightly overinflated tires.
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 drive at substantially lower or
higher speeds than normal.NOTECheck the tire pressure at least once a
month. Underinflation is the main cause
of:
 Damage to the wheels.
 Premature tire wear.
 Damage to the sidewalls.

190 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-Vee-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-Vee-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 148.

201 Car care
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.

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.

224 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 collision must be
replaced even if they are not visibly
damaged.
No attempt must be made to repair, or
modify the function of, safety belts.
