ORVR (Onboard Refueling Vapor
Recovery)All hydrocarbons formed when refuelling
will be recovered by the car and not
released into the atmosphere. The hydro-
carbons are absorbed in an evaporative
emission canister. When the engine is sub-
sequently started, the evaporative emission
canister is gradually purged as air is sucked
into it through a shut-off valve. The hydro-
carbon/air mixture passes through the evap
canister purge valve and into the engine
where it is burned. "Refueling", see page
138.
NOTEThe Trionic engine management system
continuously monitors the operation of
these systems and has on-board diag-
nostic capabilities (OBD II). If the CHECK
ENGINE light in the main instrument illu-
minates, the Trionic ECM has detected a
problem. The car will continue to operate,
but performance may be diminished. You
should have your car checked by a Saab
dealer as soon as possible.

192 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 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). 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 and shock absorbers 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 193.
 Wheels larger than 16” 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.
 When fitting wheels on a 9-3, please
note that a 15” wheel should be used
on 9-3 Coupé and 5-door models, and
nothing smaller than 16” wheel should
be used for 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.

208 Car careMaintenance  The drive belt for the compressor should
be inspected under the regular service
program.
 Clean dirt and insects away from the con-
denser and radiator to prevent clogging.
When washing the car, use the hose to
spray the radiator and condenser (located
forward of the radiator) from both sides
(both from the front of the car and from
inside the engine bay). Do not use a pres-
sure washer.
Caution: Do not use the hose when the
engine is hot.
Other than in extremely cold weather, do not
cover the radiator, e.g. with screen netting,
as this will greatly diminish its cooling capac-
ity.
Note: The A/C system will only operate
when the outdoor temperature is above the
freezing point (0°C, 32°F). Switch on the
A/C system when the car stands in a warm
place.
Headlight aimingThe vehicle is equipped with vertical and
horizontal aim indicators. The aim has been
preset at the factory and should normally not
need further adjustments. This is true even
though your vertical and horizontal aim indi-
cators may not fall exactly on the "0" (zero)
marks on their scales.
If your headlight is damaged in an accident,
the headlight aim may be affected. If you
believe your headlights need to be
re-aimed, we recommend that you take it to
your Saab dealer for service. However, it is
possible for you to re-aim your headlights as
described in the following procedure.
To check the aim, the vehicle should be
properly prepared as follows: Place the vehicle on a level pad or surface
 The vehicle should be unladen and fuel
tank full, and one person or 160 lbs.
(75 kg) on the drivers seat
 The vehicle should not have any snow, ice
or mud attached to it
 Tires should be inflated to the prescribed
pressure
 Rock the vehicle to stabilize the suspen-
sion
WARNING
Before checking/adjusting the headlight
aiming, switch off the engine to avoid
danger of fingers and hands being injured
by moving parts.
The radiator fan can start up even when
the engine is switched off.

216 Maintenance and owner assistance* These are the minimum required Emission Control System maintenance steps. Saab urges that all recommended maintenance procedures be performed
according to this program.
(b.) Change automatic transmission fluid at more frequent intervals (30,000; 90,000 miles, etc.) if car is driven in dense city traffic where the outside tem-
perature regularly reaches 90°F or higher, if car is used in a mountainous/high altitude area or for trailer towing.

224 Technical data
Fuel
Viscosity: The viscosity of oil is classified according to the SAE standard.
Nowadays, multigrade oils are always used in cars. The proper-
ties of these oils facilitate starting the car in cold weather but
mean that the oil is also viscous enough to coat all moving parts
under high pressures and with high outside air temperatures.
Multigrade oils are graded with two viscosities, e.g. 10W-30,
where the 10W meets certain viscosity requirements at -4°F
(-20°C), while the 30 fulfills requirements at a temperature of
212°F (100°C).
Basic recommendations for Saab engines:
SAE 10W-30 or 10W-40.
SAE 5W-30 can also be recommended but in which case the oil
must be semi of fully-synthetic and fulfil ACEA grade require-
ments A3/B3.
Oils which are less viscous, such as 0W/-40/50 are becoming
more common and may be used. However, the oil must be
fully-synthetic, of a well known brand, and fulfil ACEA grade re-
quirements A3/B3.
This viscosity makes starting in cold weather easier.
