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.

233 Car care and technical information
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.Rotating tiresBecause the car has front-wheel drive, the
front tires tend to wear faster than the rear
ones. New tires should always be fitted in
pairs, so that tires on the same axle have the
same amount of tread.
The tread should be at least 3 mm deep.
The wheels should be marked, L (left) and
R (right), when changing between summer
and winter (snow) tires. This ensures that
the direction of rotation of the wheels is the
same when they are refitted. Fit the tires in
best condition to the rear wheels.
Store wheels lying flat or hanging – never
standing upright.
Tire markingsAn example of the meaning of the different
markings in a tire size is given below for a
tire size of:
205/65 R15 94 V
Winter tiresWinter (snow) tires are recommended for
winter climates where the majority of your
driving will be done on snow and ice. Winter
tires should be fitted to all four wheels to
maintain a proper balance. Your Saab
dealer can advise you as to the correct size
tire for your car (if different from the original
size) and also supply Saab approved winter
tires.Tire quality grading (cars sold in
U.S.)New tires must be graded and labeled in
accordance with new Federal regulations.
Standard tests are conducted to measure
performance in the areas of traction and
temperature resistance. Refer to the tire
sidewall for the specific quality grades of the
tires provided on your new Saab. Compact
spare tires are exempt.
DOT QUALITY GRADES
 Treadwear
 Traction AA, A, B, C
 Temperature A, B, C
All passenger car tires must conform to Fed-
eral safety requirements in addition to these
grades.
WARNING
When fitting just one new pair of tires,
these should be fitted to the rear wheels,
as these are more critical to the direc-
tional stability of the car (e.g. on braking
or in a skid). The existing rear wheels
should therefore be moved to the front.
Always move left rear to left front and right
rear to right front, so that the direction of
rotation remains the same.

234 Car care and technical informationUniform 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.
Traction The 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.
Wear indicatorsThe tires incorporate wear indicators in the
form of smooth, treadless strips across the
width, which become visible when only
1.6 mm of tread remains. As soon as the
indicators become visible, new tires should
be fitted without delay.
Make sure you are familiar with the legal
limit for minimum tread depth in your
country and also any regulations gov-
erning the use of winter tires.
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.

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.

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.

248 Car care and technical information4Inspect the undercoating and touch
up if necessary.
Pay particular atten-
tion to the fenders and wheel housings,
which are exposed to abrasion by flying
gravel, etc. If the composition has worn
or flaked off, the steel must be thor-
oughly cleaned and dried before a fresh
coat is applied. The cleaning is best
done with a scraper and a steel wire
brush, followed by washing with solvent.
Apply the new coating thinly, as other-
wise it may run off or fall off when dry.
For long tripsBefore setting off on a long journey, it is
advisable to have your car checked over by
your Saab dealer.
Obtain a few important items to take along
on your journey such as spare bulbs, wiper
blades, fuses, a Poly-V-belt and the like.
You can check some points yourself before-
hand:
 Make sure that the engine is in good con-
dition.
 Check that no oil or gasoline leaks out of
the engine or gearbox/transmission.
 Check the coolant and power steering
fluid levels. Check also for leaks.
 Inspect the Poly-V-belt and replace it if it
shows any signs of hard wear.
 Check the battery charge.
 Check the tires for tread pattern and air
pressure, including the compact spare
wheel.
 Check the brakes.
 Check all bulbs.
 Check for the presence of the tool kit and
the jack in the car.
Recovery and/or
recycling of automotive
materialsA typical car consists of metals (65–75 %),
plastics (10–15 %), rubber (5 %) and small
quantities of glass, wood, paper and tex-
tiles. The recycling of metals has been com-
monplace for a long time now.
To facilitate sorting of other materials for
recycling, plastic parts, for instance, have
been marked to identify the precise nature
of the plastic.
The quantity of materials in the car that can
be recycled or recovered depends on the
scrapping facilities in different countries. EU
legislation that comes into force in 2006 will
require a minimum of 85 % of the total
weight of materials to be recycled. How-
ever, every major car salvage yard in each
market will receive details from Saab of how
the highest percentage of materials can be
reclaimed.

250 Car care and technical informationHeadlight aiming The vehicle has a visual optical headlight
aiming system equipped with vertical
aiming device. The aim has been preset at
the factory and should normally not need
further adjustments.
If your headlights are damaged in a crash,
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:
 The vehicle shall be placed so that the
headlights are 25 ft (7.6 m) from a light
colored wall or other flat surface. The
aiming area should be darkened, this will
improve your ability to see the beam of the
low beam headlight being aimed.
 The vehicle must have all four wheels on
a perfectly level surface which is level all
the way to the wall or other flat surface.
 The vehicle should be placed so it is per-
pendicular to the wall or other flat surface.
 The vehicle should be unloaded and fuel
tank full, and one person or 160 lbs.
(75 kg) on the drivers seat.  The vehicle should be fully assembled
and all other work stopped while headlight
aiming is being done.
 The vehicle should not have any snow, ice
or mud attached to it.
 Tires should be inflated to the prescribed
pressure.
 Close all doors.
 Rock the vehicle to stabilize the suspen-
sion.
Headlight aiming is done with the vehicle
low beam lamps. The high beam lamps will
be correctly aimed if the low beam lamps
are aimed properly.
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.NOTICETo make sure that your headlights are
aimed properly read all instructions
before beginning. Failure to follow these
instructions could cause damage to
headlight parts or a not correctly aimed
headlight.

and warranty book is used, but not service
coupons.
When scheduled services are performed,
your dealer will tear out the applicable
coupon and use it to check off the opera-
tions performed and enter it into the service
file at the dealership. The servicing dealer’s
stamp, along with the date and mileage at
which the service was done, should be
entered on the corresponding stub which
remains in your booklet. The booklet is your
permanent record of the services per-
formed. It also includes a log sheet for
unscheduled repairs.
It is advisable to retain receipts and, if pos-
sible, copies of shop work orders for all ser-
vice and repair work, wherever performed.
Service costsDealer pricing practices and labor for ser-
vice work vary. Saab’s recommended ser-
vice times for each service point do not
include the labor required to replace wear
items, such as wiper blades, brake pads or
tires. Nor is labor to perform other service or
repairs found to be necessary as a result of
the inspections included in these times.
Additional labor and parts will be charged
for such work when necessary, except as
covered under an applicable Saab warranty
or any optional extended service contract.
Transmission fluid changes or suspension
alignment, when necessary, are also addi-
tional.
Dealer charges for general shop material,
regulated hazardous waste removal, recy-
cling expenses or other operation costs may
also be applied to service and repair
invoices and are apt to vary by dealer and
locality.
