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.

221 Car care
When changing a wheel, take the tool kit out
first, then the spare wheel.
Changing a wheel
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
correct tightening torque cannot be
achieved.
NOTETo avoid damaging a punctured alloy
wheel this can be placed outside up in the
spare-wheel well but only while driving to
the closest workshop.
A general rule is that all heavy loads must
be well secured in the luggage compart-
ment, see page 148.
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 an acci-
dent.
Do not use the jack for any purpose
other than for jacking up the car.

224 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 collision must be
replaced even if they are not visibly
damaged.
No attempt must be made to repair, or
modify the function of, safety belts.

232 Car careAir conditioning
(A/C system)
Fault diagnosis If 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 by an authorized Saab
dealer.Important!
When the A/C system is in operation, mois-
ture from the air will condense on the evap-
orator. When the car is then parked, this
condensation will drip off the evaporator
and form a small pool of water on the
ground. This is normal. The warmer the
ambient air and the higher the humidity, the
greater the amount of condensation formed.Inadequate cooling:
a Make sure that the temperature and
air-distribution controls are in the
appropriate settings, see page 81.
b Check that the condenser (forward of
the radiator) has not become clogged
with dirt and insects.
c Make sure that the drive belt for the com-
pressor is not slipping, see page 203.
d Check the fuses for the ventilation fans
and compressor, see page 214.
NOTE 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.
All repairs and adjustments on the A/C
system must be carried out by a Saab
dealer authorized for this kind of work.
Never mix R134a and R12 refriger-
ants.
WARNING
The A/C system is pressurized. Do not
break any connections or undo A/C
system components.
Escaping refrigerant gas can cause
blindness or other injury.

233 Car care
Maintenance 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.
