230 Car careIf the tire pressure continues to drop, the
SID will issue a warning alarm when the
pressure is 0.6 bar (9 psi) below the recom-
mended value.
Reduce speed (avoid heavy braking and
violent steering wheel movements) and
stop the car as soon as it is safe to do so.
Change the wheel.Malfunction
The message shown above will be dis-
played on the SID if:
 a wheel without pressure sensor is fitted
(e.g. spare wheel)
 one, two, three or four pressure sensors
are broken or missing
 two or more detectors are missing or
broken
 the receiver malfunctions
 a fault arises in the system.
The message shown above is not displayed
if none of the wheels have sensors, such as
if winter wheels without sensors are fitted.

232 Car careWhen to checkCheck your tires once a month or more.
Don’t forget your compact spare tire. It
should be at 60 psi (420 kPa).How to CheckUse a good quality pocket-type gage to
check tire pressure. You can’t tell if your
tires are properly inflated simply by looking
at them. Radial tires may look properly
inflated even when they’re underinflated.
Be sure to put the valve caps back on the
valve stems. They help prevent leaks by
keeping out dirt and moisture.Tire Inspection and RotationTires should be rotated every 7,500 miles
(12 500 km).
Any time you notice unusual wear, rotate
your tires as soon as possible and check
wheel alignment. Also check for damaged
tires or wheels. See “When It Is Time for
New Tires” on page 233 and “Wheel
Replacement” on page 236 for more infor-
mation.
The purpose of regular rotation is to achieve
more uniform wear for all tires on the vehi-
cle. The first rotation is the most important.
When rotating your tires, always use the
correct rotation pattern. Left front tire to left
rear. Left rear tire to right front. Right front to
right rear. Right rear to left front.
Don’t include the compact spare tire in your
tire rotation.After the tires have been rotated, adjust the
front and rear inflation pressures as shown
on the Tire-Loading Information label. Make
certain that all wheel nuts are properly tight-
ened. See page 246.
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 cruising speed.
WARNING
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after a time. The wheel
could come off and cause an accident.
When you change a wheel, remove any
rust or dirt from places where the wheel
attaches to the vehicle. In an emergency,
you can use a cloth or a paper towel to do
this; but be sure to use a scraper or wire
brush later, if you need to, to get all the
rust or dirt off. See “Changing a tire” on
page 245.

Tire Chains
Notice:
If your vehicle does not have
P225/45R17 size tires, use tire chains
only where legal and only when you
must. Use only SAE Class ²S² type
chains that are the proper size for your
tires. Install them on the front tires and
tighten them as tightly as possible with
the ends securely fastened. Drive slowly
and follow the chain manufacturer’s
instructions. If you can hear the chains
contacting your vehicle, stop and
retighten them. If the contact continues,
slow down until it stops. Driving too fast
or spinning the wheels with chains on
will damage your vehicle.If a Tire Goeas Flat
It’s unusual for a tire to “blowout” while
you’re driving, especially if you maintain
your tires properly. If air goes out of a tire,
it’s much more likely to leak out slowly. But
if you should ever have a “blowout”, here are
a few tips about what to expect and what to
do:
If a front tire fails, the flat tire will create a
drag that pulls the vehicle toward that side.
Take your foot off the accelerator pedal and
grip the steering wheel firmly. Steer to main-
tain lane position, and then gently brake to
a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts
much like a skid and may require the same
correction you’d use in a skid. In any rear
blowout, remove your foot from the acceler-
ator pedal. Get the vehicle under control by
steering the way you want the vehicle to go.
It may be very bumpy and noisy, but you can
still steer. Gently brake to a stop – well off
the road if possible.
If a tire goes flat, the next part shows how to
use your jacking equipment to change a flat
tire safely.
WARNING
If your vehicle has P225/45 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.

Changing a tire
WARNING
 The car jack is designed solely for use
in changing a tire 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 wedge-shaped 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 the selector lever
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.
 If possible, make sure the jack is
standing on a firm, level surface.
 The jack should be stored correctly
under the carpeting in the trunk. If it
lies loose in the car, it could thrown
forward and cause personal injury in
the event of a crash or if the car rolls
over.
 Do not use the jack on a car other than
your Saab 9-3.
 Grit, salt and rust can clog the inner
threads of the wheel bolts if the car has
been driven for several years exclu-
sively with alloy wheels.
If steel wheels are being installed, the
bolt hole threads in the brake hubs
should be cleaned before the thinner
steel wheels are fitted. It may other-
wise not be possible to achieve the
correct clamping force, despite tight-
ening the wheel bolts to the correct
torque.
WARNING
Changing a tire can cause an injury. The
vehicle can slip off the jack and roll over
you or other people. You and they could
be badly injured. Find a level place to
change your tire. To help prevent the
vehicle from moving:
1 Set the parking brake firmly.
2 Put the shift lever in PARK (P) (auto-
matic transmission;
engage 1st gear (manual transmis-
sion).
3 Turn off the engine.
To be even more certain the vehicle won’t
move, you can put blocks at the front and
rear of the tire farthest away from the one
being changed. That would be the tire on
the other side of the vehicle, at the oppo-
site end.
