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.

208 Car careThe receiver is located in the trunk. Tire
pressure information is sent wirelessly to
the receiver.
The system checks the tire pressure when
the car is travelling over 18 mph (30 km/h).
The system is "self-learning", which means
that the position of the wheels can be
changed without requiring adjustments to
the monitoring system. The spare wheel
does not have a sensor.
The sensor batteries have an average life of
10 years. The batteries cannot be changed
but require the sensor units to be replaced.
The system does not warn if a tire is overin-
flated.
If the tire pressure drops
If the tire pressure drops 0.3 bar (4 psi)
below the recommended pressure, the SID
will issue a warning as to which tire is
affected.
Adjust the tire pressure as soon as possible.If the tire pressure continues to drop, the
SID will issue a warning alarm when the
pressure is 0.6 bar (9 psi) below the recom-
mended value.
Reduce speed (avoid heavy braking and
violent steering wheel movements) and
stop the car as soon as it is safe to do so.
Change the wheel. Tire pressure low,

Check tires.

Make a safe stop.

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.

WARNING
 The GVW and maximum axle loads must not be exceeded.
Note that if some accessories (e.g. towbar, CD changer) are
fitted, the available load capacity is reduced by the weight of
these.
 When carrying a load in the trunk, make sure that it is lashed
down securely, particularly when part or all of the rear seat is
folded down.
Trailer:
Trailer with brakes ___________________ Max. 3500 lbs.

When towing a trailer, increase the pressure
of the rear tires by 0.2 bar (3 psi).
The above speed and weight restrictions are those specified by
Saab Automobile AB.
Note that national restrictions may apply to trailer speeds and
weights (see page 157).

Oil grade
:
We recommend the use of Saab or Mobile oils, available from
you Saab dealer, for regular oil changes.
These oils are specially developed from high-quality compo-
nents to meet the demands of extended service intervals (max.
18,000 miles (30,000 km) or 2 years). Saab and Mobil oils are
tested and approved in accordance with the GM standard for
long-life oils. Such gasoline engine oils are given the designa-
tion GM-LL-A 025. The requirements are the same for diesel
oils, though these are given the designation GM-LL-B 025.
To ensure optimum engine performance, with regard to lu-
brication, the ability to dissolve residues and the neutrali-
sation of combustion products in the oil, for a service
interval of 18,000 miles (30,000 km) or a maximum of
2 years, the engine oil used must fulfil GM-LL-A 025 (gaso-
line engines) or GM-LL-B 025 (diesel engines).
Only oil of the above grades may be used.
Oils of the above grades contain the additives required for
the engine to function well. We advise against the use of
further additives.
The gasoline engine oil is unique in that not only does it fulfil the
stringent requirements demanded by API and ACEA standards
but also meets ACEA requirements for fuel-saving properties.
