263 Car care
Notice:
The wrong wheel can also cause
problems with bearing life, brake cool-
ing, speedometer or odometer calibra-
tion, headlamp aim, bumper height, vehi-
cle ground clearance and tire or tire
chain clearance to the body and chassis.
See “Changing a tire” on page 273.Used Replacement Wheels
Tire Chains
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.
WARNING
Putting a used wheel on your vehicle is
dangerous. You can’t know how it’s been
used or how far it’s been driven. It could
fail suddenly and cause a crash. If you
have to replace a wheel, use a new GM
original equipment wheel.
WARNING
If your vehicle has 235/45 R17 size tires,
don’t use tire chains, there’s not enough
clearance.
Tire chains used on a vehicle without the
proper amount of clearance can cause
damage to the brakes, suspension or
other vehicle parts. The area damaged by
the tire chains could cause you to lose
control of your vehicle and you or others
may be injured in a crash.
Use another type of traction device only if
its manufacturer recommends it for use
on your vehicle and tire size combination
and road conditions. Follow that manu-
facturer’s instructions. To help avoid
damage to your vehicle, drive slowly,
readjust or remove the device if it’s
contacting your vehicle, and don’t spin
your wheels.
If you do find traction devices that will fit,
install them on the front tires.

289 Customer Assistance and Information
Engine oil and filter changesChanging the engine oil and filter is required
at every service point. Use only a Saab
approved long-life oil filter and engine oils
meeting the SAE viscosity ratings and API
service classifications stated in the “Techni-
cal data” section of this Owner’s Manual.
The use of extra additives in the oil is not
necessary and is not recommended, and
may be harmful to turbochargers.
More frequent oil changes are recom-
mended if your vehicle is operated under
any of the following conditions:
 Most trips are less than 5–10 miles (8–
16 km). This is particularly important
when outside temperatures are below
freezing.
 Most trips include extensive idling
(frequent stop-and-go traffic).
 Most trips are through dusty areas (such
as construction zones).
 If the vehicle is used for delivery service,
police, taxi or other commercial applica-
tions.
If your driving habits match this description,
have the engine oil and filter changed in-
between normal services. These conditions
cause the engine oil to break down faster.
The Warranties and Service Record Book-
let has provisions to record extra oil
changes.
Service record retentionIt is the owner’s responsibility to retain ser-
vice records. If possible, you should keep
copies of all shop work orders for all service
and repairs, whenever performed. As indi-
cated in the new car and emission control
system warranties, it is important to docu-
ment that all necessary maintenance has
been done.
HOW THE SERVICE RECORD IS ORGA-
NIZED
The service record is comprised of a series
of coupons on which to record services as
they are performed. There are additional
coupons for documenting extra engine oil
and filter changes, extra automatic trans-
mission fluid services necessary for severe
service conditions, and brake fluid changes.
HOW TO USE THE SERVICE RECORD
COUPONS
When the car is brought to a Saab dealer for
scheduled maintenance, present the War-
ranties & Service Record Booklet to the ser-
vice manager. When the technician has
completed the service, the technician will
sign the maintenance record. The person
responsible for quality assurance at the
dealership will also sign and stamp the
record with the dealer identification stamp.
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
location.
