!If the vehicle requires frequent refilling, there
may be a leak. If you suspect a problem, have
the vehicle checked at your Saab dealer.
!Never use different brands of clutch fluid to-
gether.
!When clutch fluid is added, be careful not toallow any dirt into the tank."Recommended clutch fluidFMVSS No. 116, fresh DOT 3 brake fluid
Brake boosterIf the brake booster does not operate as described be-
low, have it checked by your Saab dealer.
1. With the engine off, depress the brake pedal sever-
al times, applying the same pedal force each time. The
distance the pedal travels should not vary.
2. With the brake pedal depressed, start the engine.
The pedal should move slightly down to the floor.
3. With the brake pedal depressed, stop the engine
and keep the pedal depressed for 30 seconds. The
pedal height should not change.
4. Start the engine again and run for about one minute
then turn it off. Depress the brake pedal several times
to check the brake booster. Brake booster operates
properly if the pedal stroke decreases with each de-
pression.

"Tire rotationTire wear varies from wheel to wheel. To maximize the
life of each tire and ensure that the tires wear uniform-
ly, it is best to rotate the tires every 7,500 miles
(12,500 km). Rotating the tires involves switching the
front and rear tires on the right hand side of the vehicle
and similarly switching the front and rear tires on the
left hand side of the vehicle. (Each tire must be kept on
its original side of the vehicle.)
Replace any damaged or unevenly worn tire at the
time of rotation. After tire rotation, adjust the tire pres-
sures and make sure the wheel nuts are correctly
tightened.After driving approximately 600 miles (1,000 km),
check the wheel nuts again and retighten any nut that
has become loose.
"Tire replacementThe wheels and tires are important and integral parts
of your vehicle’s design; they cannot be changed arbi-
trarily. The tires fitted as standard equipment are opti-
mally matched to the characteristics of the vehicle and
were selected to give the best possible combination of
running performance, ride comfort, and service life. It
is essential for every tire to have a size and construc-
tion matching those shown on the tire label and to
have a speed symbol and load index matching those
shown on the tire label.
Using tires of a non-specified size detracts from con-
trollability, ride comfort, braking performance, speed-
ometer accuracy and odometer accuracy. It also cre-
ates incorrect body-to-tire clearances and inappropri-
ately changes the vehicle’s ground clearance.
All four tires must be the same in terms of manufactur-
er, brand (tread pattern), construction, and size. You
are advised to replace the tires with new ones that are
identical to those fitted as standard equipment.
For safe vehicle operation, Saab recommends replac-
ing all four tires at the same time.
