2003 SAAB 9-3 ESP

163 Starting and driving
Driving with the trunk lid
openAvoid driving with the trunk lid partly or fully
open, since exhaust fumes can be drawn
into the cabin.
If you must drive with the trunk lid open,
close all windows and the sunroof (if fitted)
and set the cabin fan to its highest speed
setting.
Driving in deep water Driving at night
Bear in mind the following points, especially
when driving at night:
 Nighttime driving requires your full
concentration
 Do not rush. Count on your journey taking
slightly longer.
 The number of drivers under the influence
of drugs is likely to be greater at night than
during the day.
 Do not stare at the headlights of oncom-
ing vehicles.
 Avoid driving at night if you have poor
eyesight. Night vision deteriorates with
age.
 Keep your car’s headlights, windows and
mirrors clean. Also, if you wear glasses,
make sure they are clean.
 Make sure you are well rested before
starting a long journey. Take a break
every other hour.
 Only eat light meals. Heavy meals have a
tendency to induce tiredness.
 Wild animals prefer to move at dusk and
dawn.
 Check the headlight levelling setting (see
page 73).
NOTICEDo not drive in puddles or water deeper
than 7 in. (20 cm) and do not drive faster
than at idling speed. Water can otherwise
be sucked into the engine. The engine will
be damaged if water enters the intake
system.

180 Car careNote:
If incorrect coolant is used or added, the life-
time properties will be affected. Even if the
coolant is flushed from the system and
replaced with life-time coolant, life-time
properties are no longer retained and the
coolant must then be drained and replaced
at regular intervals.
Brake/clutch fluid and
brake padsCheckingBrake fluid should be changed according to
the service program. Refer to the Warranty
and Service Book.
The brake and clutch fluid reservoir is trans-
parent to facilitate checking of the fluid level.
The fluid level should lie between the MAX
and MIN marks.
Top up as necessary with DOT 4 brake
fluid. Do not use DOT 5 fluid.
Use only new brake fluid from a sealed
container.
The brake fluid level will fall somewhat as
the brake pads wear. The MAX level in the
reservoir corresponds to the amount of
brake fluid required with new brake pads. If
the fall in fluid level is moderate, due to
normal brake pad wear, topping up is not
necessary.If the brake fluid should require chang-
ing, this must be carried out at a Saab
dealer.
NOTICEIf the cooling system needs topping up,
mix the antifreeze with the appropriate
quantity of drinking water or distilled
water before adding it to the system.
If undiluted 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 ther-
mostat has opened to allow full circula-
tion.
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
regularly, as specified in the service
program.

206 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
available.
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.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.
Do not take it for granted that a wheel/tire
combination will work in the best possible
way, just because it can be fitted to the car.
To ensure that the speedometer is as accu-
rate as possible it should be reprogrammed
if wheels of a different dimension are fitted.
Contact a Saab dealer.
NOTICEAlways consult your Saab dealer before
changing the car’s wheels or tires on your
Saab.
Wide wheels and tires with side walls that
are too low can:
 be damaged in potholes, etc.
 cause springs, shock absorbers and
wheel bearings and body mountings
to be overloaded
 cause the wheels to come into contact
with chassis and body components
 affect the function of the Electronic
Stability Program (ESP).
The speed and load limits of the tires
must not be exceeded; see page 209.
Wheels larger than 18" must not be fitted
on the Saab 9-3. The permissible offset is
1.61 inch (41 mm).

207 Car care
Tire pressure
Note: Low tire pressure also causes prema-
ture tire wear and increased fuel consump-
tion.
Adjust the tire pressure to match the current
load and speed of the car (see page 245).
The stated tire pressures apply to cold tires,
i.e. tires that are the same temperature as
the outside air temperature. Tire pressure
increases as the tires become warm (e.g.
during highway driving) by approximately
0.3 bar (4 psi). When the temperature of the
tires changes by 50°F (10°C), the tire pres-
sure 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.
Soft tires will cause faster wear than over-
pressurized tires.
If a valve is leaking, simply unscrew it and fit
a new one.
Note: Remember to adjust the tire pressure
if you change the load in the car or intend to
cruise at a speed that is substantially differ-
ent from normal.
Automatic tire pressure monitoring(option, certain variants only)
The pressure monitoring system consists of
a sensor in each wheel, a detector in each
wheel housing and a receiver. The sensors
are located inside the wheels directly adja-
cent to the air valves.
WARNING
Check the tire pressure at least once a
month and before long journeys. Under-
inflation can result in:
 punctures
 separation of the tire and tread
 damage to the sidewalls
 damage to the rims on poor roads
 poor handling characteristics.
WARNING
The system is intended to aid the driver.
The driver is always ultimately responsi-
ble for ensuring that the tire pressure is
correct.NOTICEGreat care must be taken when changing
tires so as not to damage the sensors that
are integrated in the valves.

211 Car care
TemperatureThe temperature grades are A (the highest),
B, and C, representing the tire’s resistance
to the generation of heat and its ability to dis-
sipate heat when tested under controlled
conditions on a specified indoor laboratory
test wheel. Sustained high temperature can
cause the material of the tire to degenerate
and reduce tire life. Excessive temperature
can lead to sudden tire failure. The grade C
corresponds to a level of performance
which all passenger car tires must meet
under the Federal Motor Vehicle Safety
Standard No. 109.
Grades B and A represent higher levels of
performance on the laboratory test wheel
than the minimum required by law.
Wear indicatorsThe tires incorporate wear indicators in the
form of smooth, treadless strips across the
width, which become visible when only 2/
32" (1.6 mm) of tread remains. As soon as
the indicators become visible, new tires
should be fitted without delay.
Make sure you are familiar with the legal
limit for minimum tread depth in your
country and also any regulations gov-
erning the use of winter (snow) tires.
WARNING
The temperature grade for a tire is estab-
lished for a tire that is properly inflated
and not overloaded. Excessive speed,
underinflation, or excessive loading,
either separately or in combination, can
cause heat buildup and possible tire fail-
ure.

214 Car careChanging a wheel
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 wedge-shaped 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 the selector lever
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.
 If possible, make sure the jack is
standing on a firm, level surface.
 The jack should be stored correctly
under the carpeting in the trunk. If it
lies loose in the car, it could thrown
forward and cause personal injury in
the event of a crash or if the car rolls
over.
 Do not use the jack on a car other than
your Saab 9-3.
 Grit, salt and rust can clog the inner
threads if the car has been driven for
several years exclusively with alloy
wheels.
If steel wheels are now fitted, the bolt
hole threads in the brake hubs should
be cleaned before the thinner steel
wheels are fitted. It may otherwise not
be possible to achieve the correct
clamping force, despite tightening the
wheel bolts to the correct torque.

217 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 cruising speed.
Safety beltsCheck the function of the safety belts regu-
larly as follows:
 Hold the diagonal strap and pull it sharply.
The safety belt should lock and it should
not be possible to withdraw it further.
Check the anchorage points in the floor.
They must not have suffered rust 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.
Upholstery and trimTo remove fluff and hairs from the seats,
door armrests and headlining, use a
vacuum cleaner, a moist lint-free cloth, or a
clothes brush. Remove spots and dirt using
a cloth moistened with lukewarm soapy
water.
When using a stain remover, always work
from the outside towards the centre to avoid
leaving a ring. If a soiled ring or spot should
remain, it can usually be removed using
lukewarm soapy water or water alone.
Spots left by liquids, such as soft drinks or
thin oil, must be removed at once with an
absorbent material, such as kitchen towel-
ling. Then clean with a stain remover.
White spirit is recommended for removing
grease and oil stains. A medium stiff brush
may also be used.
WARNING
If the car is involved in a crash, the safety
belts, belt pretensioners and other asso-
ciated components must be inspected at
a Saab dealer.
Never make any alterations or repairs to
the safetybelts yourself but visit a Saab
dealer.
