2003 SAAB 9-5 ESP

232 Car care and technical informationWheels Alternative 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.
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 workshop.
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 page 268). 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.
NOTICEAlways consult your Saab dealer before
changing the wheels and tires on your
Saab.
Wide wheels and tyres with sidewalls that
are too low can:
 be damaged in potholes etc.
 cause springs, shock absorbers and
wheel bearings and body mountings
can be overloaded.
 cause that the wheels can come into
contact with chassis and body compo-
nents.
 can affect the function of the Elec-
tronic Stability Program (ESP).
The speed and load limits for the tires
must not be exceeded; see page 233.
Wheels larger than 17” must not be fitted.
The maximum permissible offset is
49 mm.
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
 Premature tire wear
 Increased fuel consumption.

235 Car care and technical information
Temperature The 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, and excessive temper-
ature can lead to sudden tire failure. The
grade C corresponds to a level of perfor-
mance 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.
Date 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 two last
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.
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.

Changing 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 sup-
port 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.
 Grit, salt and rust can clog the inner
threads of the wheel bolts if the car has
been driven for several years exclu-
sively 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 required
clamping force despite tightening the
bolts to the correct torque.

241 Car care and technical information
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 appear 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 give rise to 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.
WARNING
Grit, salt and rust can clog the inner
threads if the car has been driven for sev-
eral 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 possi-
ble to achieve the required clamping force
despite tightening the bolts to the correct
torque.

247 Car care and technical information
What causes rust?Steel body panels of automobiles are sub-
ject to rusting whenever air and moisture
manage to penetrate the protective finish,
and body panels may rust through if the pro-
cess is unchecked. Rusting can occur wher-
ever water is trapped or where the car’s
panels are continuously damp. Damage to
paint and undercoating by stones, gravel
and minor crashes immediately exposes
metal to air and moisture. Road salts used
for de-icing will collect on the bottom of the
car and promote rusting. Areas of the coun-
try with high humidity have great potential
for rust problems, especially where salt is
used on roads or there is moist sea air.
Industrial pollution (fallout) may also
damage paint and promote rusting.
Preventive maintenanceThe following procedures are necessary to
help protect against rusting. Refer also to
the terms and conditions of the Sheet Metal
Coverage described in the warranty book-
let.
1
Wash the car frequently, and wax at
least twice a year.
Under adverse con-
ditions, where there is a rapid buildup of
dirt, sand or road salt, wash your car at
least once a week. After extreme expo-
sure to salted snow or slush, evidenced
by a white film on the car, wash the car
immediately. Frequent washing will pre-
vent paint damage from acid rain and
other airborne contaminants such as
tree sap and bird droppings. If any of
these contaminants are noticed on the
car the finish should be washed immedi-
ately.
 Begin washing by rinsing the entire car
with water to loosen and flush off heavy
concentrations of dirt (include the
underbody).
 Sponge the car with a solution of either
a good quality car soap or mild general
purpose (dish washing) detergent and
water.
 Rinse car thoroughly with clean water.
 After washing, check and clear all
drains in doors and body panels.
 Wipe the car dry, preferably using a
chamois.2
Clean the underside of the car during
the winter.
Use high pressure water to
clean the car’s underside (floor panels,
wheel wells) at least at mid- winter and
in the spring.
3
Inspect the car frequently for leaks or
damage, and arrange for needed
repairs promptly.
After washing or after
heavy rain, check for leaks. When wash-
ing the car inspect body surfaces for
paint damage. While checking for leaks,
lift the floor mats and check beneath
them. Water can collect in these areas
and remain for prolonged periods. Dry
any wet areas including the floor mats.
Have leaks repaired as soon as possi-
ble.
Use touch-up paint to repair small
scratches or minor finish damage. Areas
where metal is exposed will rust quickly
and MUST be repaired immediately by
touch-up or professional repainting.
Rust must be removed, the bare metal
primed and painted. Major body
damage should be repaired immediately
and new panels or exposed areas
should be undercoated with anti- corro-
sion material.
Repairs of this type are the owner’s
responsibility and are not covered under
warranty.

261 Specifications
Engine oilOil recommendation:

We recommend the use of Saab or Mobil oils, available from
your Saab dealer, for regular oil changes. These oils fulfil
Saab’s requirements as wells as the most stringent require-
ments set by API and ACEA classifications.
Basic recommendations for Saab engines:
SAE 5W-30 or 0W-30, 5W-40.
The oil should be semi or fully synthetic and fulfill grade require-
ments for ACEA A3/B3, API SJ or higher. In addition to API and
ACEA the ILSAC GF-3 specification is approved for use in appli-
cable markets.
Fully synthetic oils with viscosity’s 0W-40/50 of well known
brands and fulfilling minimum ACEA A3/B3 are also recom-
mended, especially for extreme driving conditions.Oil specification.
Oil for gasoline engines is classified by the API (American Petro-
leum Institute) and ACEA (European Automobile Manufacturers
Associations) standards.
API classifies engine oil into grade classes SH (since 1993) and
SJ (since 1996). The SJ class fulfils more stringent requirements
and has lower phosphorous level. A new grade API SL, intro-
duced 2001, fulfils even higher requirements.
These grade classes are most often combined with correspond-
ing classes for diesel engines. The class designations for diesel
engines begins with the letter "C" (Commercial). For example a
grade combination suitable for both types of engine could be API
SJ/CF or SL/CF.
Under the ACEA nomenclature, oils are divided into Class A for
gasoline engines and Class B for diesel engine passenger cars.
There is a further class for heavy diesel engines. Each class is
divided into grades: 1,2 and 3 where grades 2 and 3 normally
encompass semi- and fully synthetic oils. The diesel class also
has a fourth grade, B4, which encompasses tests and regula-
tions aimed at improving the performance of direct injection die-
sel engines.
In the same way as in the API system, gasoline and diesel
engine specifications are combined for products that can be
used in both types of engine. For example, a grade designation
could be ACEA A2/B2 or ACEA A3/B3, B4.

By cold tires is meant tires that are the same temperature as the surrounding
air temperature.
The values for tire pressure in the table above are for tires at 68°F (20°C).
The tire pressure will increase as the tires become warm (e.g. during motor-
way driving), and decrease as they cool.
When the temperature of the tires increase or decrease by 10 degrees the
tire pressure will correspondingly increase or decrease by 2 psi/10 kPa
(0.1 bar).
