SAAB 9-3 2002 Owners Manual

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.

212 Car careRotating the tires Because of front wheel drive, the front tires
tend to wear faster than the rear ones. New
tires should always be fitted in pairs, so that
tires on the same axle have the same
amount of tread.
The wheels should be marked, L (left) and
R (right), when changing between summer
and winter (snow) tires. This ensures that
the direction of rotation of the wheels is the
same when they are refitted. Fit the tires in
best condition to the rear wheels.
Store wheels lying flat or hanging – never
standing upright.
Tire markingsAn example of the meaning of the different
markings in a tire size is given below for a
tire size of 205/55 R16 91V:
Winter tiresWinter (snow) tires are recommended for
winter climates where the majority of your
driving will be done on snow and ice. Winter
tires should be fitted to all four wheels to
maintain a proper balance. Your Saab
dealer can advise you of to the correct size
tire for your car (if different from the original
size) and also supply Saab approved winter
tires pre-mounted on steel or alloy rims.Tire quality grading (cars sold in
U.S.)New tires must be graded and labeled in
accordance with new Federal regulations.
Standard tests are conducted to measure
performance in the areas of traction and
temperature resistance. Refer to the tire
sidewall for the specific quality grades of the
tires provided on your new Saab. Compact
spare tires are exempt.
DOT QUALITY GRADES
 Treadwear.
 Traction AA, A, B, C.
 Temperature A, B, C.
All passenger car tires must conform to Fed-
eral safety requirements in addition to these
grades.
WARNING
When fitting just one new pair of tires,
these should be fitted to the rear wheels,
as these are more critical to the direc-
tional stability of the car (e.g. on braking
or in a skid). The existing rear tires should
therefore be moved to the front. Always
move left rear to left front and right rear to
right front, so that the direction of rotation
remains the same.

213 Car care
Uniform Tire Quality Grading (US)Quality grades can be found where applica-
ble on the tire sidewall between tread shoul-
der and maximum section width. For exam-
ple:
Treadwear 200 Traction AA
Temperature ATreadwearThe treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions on
a specified government test course. For
example, a tire graded 150 would wear one
and one half (1 1/2) times as well on the gov-
ernment course as a tire graded 100. The
relative performance of tires depends upon
the actual conditions of their use, however,
and may depart significantly from the norm
due to variations in driving habits, service
practices and differences in road character-
istics and climate.
TractionThe traction grades, from highest to lowest,
are AA, A, B and C. These grades represent
the tire’s ability to stop on wet pavement as
measured under controlled conditions on
specified government test surfaces of
asphalt and concrete. A tire marked C may
have poor traction performance.
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.
WARNING
The traction grade assigned to a tire is
based on straight-ahead braking, traction
test and does not include acceleration,
cornering, hydroplaning or peak traction
characteristics.
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 careDate codeTires should be regarded as perishable
goods. As the tires age, the rubber becomes
progressively harder, and the roadholding
ability of the tires diminishes. This is partic-
ularly true on winter tires.
Tires now have a date-code marking for the
year of manufacture. The first two digits
denote the week number and the last two
digits the year. The ”<” symbol points to the
year.
Accordingly, a date code of 0200 signifies
that the tire was manufactured in week 02,
2000.
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.
Compact spare wheelThe compact spare is light and easy to
handle when changing the wheel. Its use is
only permitted when a standard tire has sus-
tained a puncture. The maximum life of the
tire is only 2000 miles (3,500 km).
Do not exceed 50 mph (80 km/h) with the
compact spare fitted.
The compact spare should be inflated to
60 psi (420 kPa). Carry the punctured tire in
the spare-wheel well under the trunk floor.
Have the standard tire repaired and refitted
as soon as possible
Driving considerations with compact spare
wheel/tire fitted, see page 184.
The spare wheel, the tools and the jack with
its crank are carried under a panel in the
trunk.

215 Car care
When changing a wheel, take the tool kit out
first, then the spare wheel.
Changing a wheel
NOTE
To avoid damaging an alloy wheel with a
flat tire, this can be placed outside up in
the spare-wheel well but only while driv-
ing to the closest workshop.
A general rule is that all heavy loads must
be well secured in the luggage compart-
ment, see page 142.
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 a crash.
 Do not use the jack for any purpose
other than for jacking up the car.
 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 cor-
rect tightening torque cannot be
achieved.

216 Car careWhen 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. See page 217.
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 Clean the contact surfaces between the
rim and hub.
8 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 218 for sequence.
9 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)NOTE Do not position the jack under the rear
axle or under the rear floor.
 Only use the points specified on
page 217.

10 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 172. NOTE
When refitting wheel covers (where
applicable), make sure that the valve
protrudes through the hole in the wheel
cover.
NOTEDo not overtighten the bolts using an
impact wrench: not only can this damage
the wheels but it can also make it impos-
sible to undo the bolts using the wheel
wrench in the car’s toolkit.NOTESaab 9-3 Viggen: The minimum permis-
sible wheel diameter is 16”, due to the
size of the brake discs.

Position for jack, Saab 9-3 Viggen. The front and rear jacking points are located behind
covers that must be removed. Remove the covers by taking hold of the lower edge and
pulling outwards. When replacing the covers, fit the catches along the top edge first and
then press home the cover.

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.

219 Car care
Upholstery and trimTo remove fluff or hairs from the seat uphol-
stery or headlining, use a moist, lint-free
cloth or a special lint remover (brush or
roller). Remove any dirty marks using a
cloth moistened with lukewarm soapy
water.
When using a stain remover, always work
from the outside towards the center 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.
Wet patches left by spilled soft drinks or thin
oil must be wiped off immediately using an
absorbent material, such as paper toweling,
and treated with stain remover.
Isopropyl alcohol is recommended for
removing grease or oil stains, and a
semi-stiff brush may also be used.
Cleaning and caring for leather
upholsteryThe principal reason for treating leather
upholstery is to maintain its elegant appear-
ance and to provide it with a protective film.
Discoloration caused by dust and wear
mainly affects the lighter shades, although
this is not detrimental to the leather –
indeed, the patina resulting from use is often
considered desirable in leather. But if the
leather is allowed to become too grubby, it
can start to look shabby.
The leather upholstery should be cleaned
and reconditioned twice a year in conjunc-
tion with spring and autumn inspections. In
very warm, dry climates the leather may
need more regular reconditioning. Recom-
mended conditioner - Saab Leather Care
Lotion.
Do not use unknown harsh polishing
agents, cleaning agents, sprays, coarse
soap or hot water.
The leather will be clean and attractive for
many years.
Textile carpetingVacuum clean the carpeting regularly. Car-
pets can also be cleaned using a brush, or
carpet shampoo applied with a sponge. Do
not use vacuum cleaners outdoors unless
they are properly grounded.
ProCarManuals.com

220 Car careEngine bayClean the engine compartment using an
engine detergent and rinse with hot water.
Cover the headlights. Do not use a
high-pressure washer
Avoid spraying the hood liner, as this can
become heavy and hang down and touch
the engine when the hood is closed.
Do not use gasoline as a cleaning agent or
solvent when carrying out repairs or mainte-
nance. Saab recommends the use of envi-
ronmentally safe degreasing agents.
WashingThe bodywork must be washed frequently.
When the car is new, the body should be
washed by hand using plain cold water and
a clean, soft brush, or in a brushless car-
wash that uses mild detergent. Automatic
carwashes with brushes should be avoided
when the car is new. Do not use automatic
car washes for the first five or six months,
before the paintwork has hardened prop-
erly. Thereafter, use a high quality car wash
soap added to lukewarm water.
Do not use a pressure washer at close
range on stone chip damage, scratches or
other damage to the paintwork. The paint
can otherwise start to flake.
Remove any bird droppings without delay,
as these can discolor the paintwork and
prove difficult to polish out.
Use a soft cloth moistened with methyl alco-
hol to remove splashes of tar or asphalt. Do
not use strong cleaners, as these can dry
out the paintwork. The underside of the car also needs wash-
ing regularly, and this should be done very
thoroughly at the end of winter. Clean the
underside of the car by hand if the car is usu-
ally washed in an automatic car wash with-
out special facilities for underbody cleaning.
Never wash or leave the car to dry in the
sun, but wipe it dry with a chamois leather
immediately after washing to avoid smears
and streaks.
Clean the window glass inside and out using
a high quality window cleaner. This is partic-
ularly important when the car is new, as
upholstery and trim have a tendency to
sweat a little at first.
Keep the glass well cleaned, as this helps to
prevent misting.NOTEAvoid using any alcohol-based cleaners
on the front and rear light clusters, as
these can cause cracking of the lenses.
