If you check the oil level just after stopping the engine,
wait a few minutes for the oil to drain back into the oil
pan before checking the level.
Just after driving or while the engine is warm, the en-
gine oil level reading may be in a range between the
upper level and the notch mark. This is caused by ther-
mal expansion of the engine oil.
To prevent overfilling the engine oil, do not add any
additional oil above the upper level when the engine is
cold."Changing the oil and oil filterChange the oil and oil filter according to the mainte-
nance schedule in the “Saab Warranty and Service
Record Booklet”.
The engine oil and oil filter must be changed more fre-
quently than listed in the maintenance schedule when
driving on dusty roads, when short trips are frequently
made, or when driving in extremely cold whether.
1. Warm up the engine by letting the engine idle for
about 10 minutes to ease draining the engine oil.
2. Park the vehicle on a level surface and stop the en-
gine.
3. Remove the oil filler cap.
Do not touch the exhaust manifold or turbo-
charger. These get very hot when the enginehas been running.2.0-liter turbo models

"Wheel replacementWhen replacing wheels due, for example, to damage,
make sure the replacement wheels match the specifi-
cations of the wheels that are fitted as standard equip-
ment. Replacement wheels are available from Saab
dealers.Use only those wheels that are specified for
your vehicle. Wheels not meeting specifica-
tions could interfere with brake caliper opera-
tion and may cause the tires to rub against the
wheel well housing during turns. The resulting
loss of vehicle control could lead to an acci-dent.NOTEWhen any of the wheels is removed and replaced
for tire rotation or to change a flat tire, always
check the tightness of the wheel nuts after driving
approximately 600 miles (1,000 km). If any nut is
loose, tighten it to the specified torque.
Aluminum wheelsAluminum wheels can be scratched and damaged
easily. Handle them carefully to maintain their appear-
ance, performance, and safety.
!When any of the wheels is removed and replaced
for tire rotation or to change a flat, always check the
tightness of the wheel nuts after driving approximately
600 miles (1,000 km). If any nut is loose, tighten it to
the specified torque.
!Never apply oil to the threaded parts, wheel nuts, or
tapered surface of the wheel.
!Never let the wheel rub against sharp protrusions or
curbs.
!Be sure to fit tire chains on uniformly and completely
around the tire, otherwise the chains may scratch the
wheel.
!When wheel nuts, balance weights, or the center
cap is replaced, be sure to replace them with genuine
Saab parts designed for aluminum wheels.
