246 Car careTire 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 have a code that specifies their date of
manufacture. The first two digits denote the
week number and the last two digits the
year.
Accordingly, a date code of 3701 signifies
that the tire was manufactured in week 37,
2001.
Compact spareThe compact spare is light and easy to
handle when changing the tire. Its use is
only permitted when a standard tire has sus-
tained a puncture. The maximum life of the
tire is only just over 2,000 miles (3,500 km).
Do not exceed 50 mph (80 km/h) with the
compact spare fitted.
The tire pressure should be 60 psi
(420 kPa). Put the punctured tire in the
spare wheel well under the trunk floor.
“Driving with the compact spare tire”, see
page 193.
Have the standard tire repaired and refitted
as soon as possible.The spare tire, the tools and the jack with its
crank are carried under a panel in the trunk.
Fold the carpeting forward to ease access to
the tools and spare tire.
The screwdriver handle has a “button” for
removing plastic rivets. This type of rivet
must be removed when changing the light
bulb in the trunk lid (see page 221).
WARNING
The spare tire or punctured tire must be
stowed under the trunk floor, and secured
in place with the retaining nut.

247 Car care
Your Saab is equipped with a trip computer
and you can use its “Speed warning” func-
tion, to monitor driving speed since you
must not exceed 50 mph (80 km/h).
NOTICETo 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 143).

249 Car care
When the car has to be lifted, the jack must
be positioned at one of the four jacking
points (front or rear) under the sill members.
If a floor jack is used, the lifting plate must
be positioned under the normal jacking
points, see illustration. If the car is equipped
with a towbar, the jack can also be placed
under this.
1 Wind the jack up to a suitable height
before placing it under the jacking point.
Each jacking point is indicated by an
arrow on the sill (see illustration).
Make sure that the jack fully engages
the jacking point in the underside of the
sill member and that the entire foot of the
jack is steady and flat on the ground.
The jack must not stand on snow, ice or
similar.
Wind up the jack until it just begins to lift
the car.2 It is not necessary to remove the wheel
cover.
If, none the less, you wish to remove the
wheel cover, take hold of the outer edge
and pull it straight out.
Loosen the wheel bolts half a turn.
3 Wind the jack to raise the wheel clear of
the ground. Remove the wheel bolts and
lift off the wheel.4 Clean any rust or dirt from the contact
surfaces between the wheel and brake
disc. Do not wipe away the grease in the
wheel hub.
5 Add a thin layer of grease on the bolts
before fitting, see page 251. Fit the
wheel and screw in the bolts in the
sequence shown on page 251 (opposite
pairs).
Tighten the bolts enough for the bolts
and wheel to be seated correctly.
6 Lower the car and tighten the wheel
bolts to torque in sequence as shown on
the following page.
Tightening torque:
Light-alloy wheels: 80 ft.lb. (110 Nm).
Steel wheels: 80 ft.lb. (110 Nm).NOTICEApply the jack only to the jacking points
indicated on the body.

7 Retouching the wheel bolts after twenty
or so miles.
Tightening torque:
Light-alloy wheels: 80 ft.lb. (110 Nm).
Steel wheels: 80 ft.lb. (110 Nm).
We advise against using wheels with large
ventilation slots in winter, as the brake com-
ponents are then more exposed to slush,
road salt and grit.
If you fit wheels of a different dimension, the
speedometer can be reprogrammed to
ensure it is as accurate as possible. Contact
a Saab dealer.
Driving with tire chains, see page 182
NOTICE Do not overtighten the bolts using a
impact wrench: not only can this
damage the wheels but it can also
make it impossible to undo the bolts
using the wheel wrench in the car’s
toolkit.
 When refitting a wheel cover, make
sure that the valve protrudes through
the marked recess in the wheel cover.
Do not wipe away the grease in the wheel
hub.
Clean any rust or dirt from the contact sur-
faces between the wheel and brake disc.

Air conditioning (A/C)
TroubleshootingIf a fault occurs in the A/C system, there are
a number of checks you can perform your-
self. If the fault persists, however, have the
system checked at a Saab dealer.
Note:
When the A/C system is running, the intake
air is dehumidified. The resultant condensa-
tion that forms on the evaporator is drained
off under the car. When the car is parked,
this may result in a small puddle forming on
the ground. The warmer the air and the
higher the relative humidity, the more con-
densation will be produced.Inadequate coolinga Check that the controls for temperature
and air distribution are correctly set; see
“Manual climate-control system” on
page 103.
b Check that the condenser (in front of the
radiator) has not become clogged with
dirt and insects.
c Make sure that the compressor drive
belt does not slip (see page 210).
d Check the fuses for the ventilation fans
and compressor (see page 229).
Maintenance The compressor drive belt should be
inspected under the regular service
program.
 Clean away dirt and insects from the
condenser and radiator to prevent clog-
ging. When washing the car, use the hose
to spray the radiator and condenser
(located in front of the radiator) from both
sides (both from the front of the car and
from inside the engine bay). Do not use a
pressure washer.
Caution: Do not hose down the radia-
tor and condenser while the engine is
hot.
Other than in extremely cold weather, do not
screen the radiator, e.g. with netting, as this
will greatly diminish its cooling capacity.
 Applicable to the manual climate control
system - During cold months the air condi-
tioning should be switched on once or
twice a month and run for 5–10 minutes
during highway driving once the engine is
warm.
This action saves the gaskets in the
compressor from being spoiled. The
compressor uses a lubricant that circu-
lates with the coolant.
WARNING
 All repairs and adjustments to the A/C
system must be carried out at a Saab
dealer authorized for this kind of work.
 The A/C system is pressurized. Do not
break any connections or undo A/C
system components.
 Escaping gas can cause eye injury or
other personal injury.NOTICE The A/C system is designed for use
with R134a refrigerant.
 Refrigerant handling requires special
equipment and special procedures for
charging and draining the system.
 Never mix R 134a with other refriger-
ants.
NOTICEDo not use a pressure washer when
cleaning the condenser or radiator due to
the risk of damage.

Fuel
Engines
Recommended oil viscosities.
Viscosity is a measurement of the oils thickness. The thickness
influences, among other things, the fuel economy. For best
function Saab recommends:
For gasoline engines:
SAE 0W-30, SAE 5W-30 or SAE 0W-40 engine oil.
Extra engine oil additives.
Don't add anything to your oil. The recommended oils are all
you will need for good engine performance and protection.
When to change engine oil.
Your vehicle has a display (SID) where time for service will be
shown. Based not only on mileage but also on driving condi-
tions the mileage at which a service will be indicated can vary
considerably.
Under normal circumstances the service indication will come on
at or around 15 000 miles or 2 years.
For this service system to work it is of outmost importance that
the right engine oil is used.
When the message for service is displayed you need to have
the required service done as soon as possible.
After the service your service personnel will reset the service in-
dicator. It is important to reset the service indicator in order to
optimize the time to the next service.
Oil capacity, including filter (oil change) 6.3 qts. (6.0 l)Fuel tank capacity ________________ 16.05 U.S. gal. (61 l)
For optimum performance Saab recom-
mends: 2.0t 175 hp – AON 90.
2.0T 210 hp – AON 90.
Gasoline with a lower octane rating can be used, although not
lower than AON 87. However, engine performance will fall
slightly and heavy loading and laboring should be avoided. For
optimum performance, use the recommended grade of fuel.
