166 Starting and drivingESP OFF
lights up under the speedometer if:
 a fault has been detected and the system
has therefore been switched off
 the system has been switched off
manually
ESP indicator lightWhen the remote control is turned to the ON
position, the lamp is lit for about 4 seconds
while the system performs self-diagnosis.
The light under the speedometer
comes on for a short period of time when the
ESP system is operative.
Operation of the ESP indicates reduced
cohesion between the tires and the road,
and that extra care should be taken by the
driver.Turning ESP system offThe system can be turned off manually with
the ESP button, whereupon the light
under the speedometer will come on. The
car must be travelling slower than 35 mph
(60 km/h). The TCS is also disengaged.
The ESP is always engaged during braking,
even if it has been switched off manually
with the ESP button.If a fault is detected in the system, the
following message will be displayed on
the SID:
The cruise control system (if active) will
automatically be disengaged if the ESP is
operative.
Stability control failure.
Contact Saab dealer.
NOTICEChanges to the chassis, such as a
change of wheels, shock absorbers or
springs, could affect the function of the
ESP system.
Always consult your Saab dealer before
changing any chassis components.

229 Car care
Automatic tire pressure
monitoring(option, certain variants only)
The pressure monitoring system consists of
a sensor in each wheel, a detector in three
wheel housings and a receiver. The sensors
are located inside the wheels directly adja-
cent to the air valves.Tire pressure information is sent wirelessly
to the receiver.
The system checks the tire pressure when
the car is travelling over 18 mph (30 km/h).
The system is “self-learning”, which means
that the position of the wheels can be
changed without requiring adjustments to
the monitoring system. The spare wheel
does not have a sensor.
The sensor batteries have an average life of
10 years. The batteries cannot be changed
but require the sensor units to be replaced.
The system does not warn if a tire is overin-
flated.
If the tire pressure drops
If the tire pressure drops 0.3 bar (4 psi)
below the recommended pressure, the SID
will issue a warning as to which tire is
affected.
Adjust the tire pressure as soon as possible.
WARNING
The system is intended to aid the driver.
The driver is always ultimately responsi-
ble for ensuring that the tire pressure is
correct.NOTICEGreat care must be taken when changing
tires so as not to damage the sensors that
are integrated in the valves.
Tire pressure low,

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.

234 Car careThe 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.
Do not take it for granted that a wheel/tire
combination will work in the best possible
way, just because it can be fitted to the car.
To ensure that the speedometer is as accu-
rate as possible it should be reprogrammed
if wheels of a different dimension are fitted.
Contact a Saab dealer.
Because of 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.
Store wheels lying flat or hanging – never
standing upright.
NOTICEAlways consult your Saab dealer before
changing the car’s wheels or tires on your
Saab.
Wide wheels and tires with side walls that
are too low can:
 be damaged in potholes, etc.
 cause springs, shock absorbers and
wheel bearings and body mountings
to be overloaded
 affect the function of the Electronic
Stability Program (ESP).
The speed and load limits of the tires
must not be exceeded; see page 239.
Wheels larger than 17" must not be fitted
on the Saab 9-3 for reasons above. The
permissible offset is 1.61 inch (41 mm).
WARNING
Mixing tires could cause you to lose
control while driving. If you mix tires of
different sizes or types (radial and bias-
belted tires), the vehicle may not handle
properly, and you could have a crash.
Using tires of different sizes may also
cause damage to your vehicle. Be sure to
use the same size and type tires on all
wheels. It’s all right to drive with your
compact spare temporarily, it was devel-
oped for use on your vehicle. See
“Compact spare tire” on page 243.
WARNING
If you use bias-ply tires on your vehicle,
the wheel rim flanges could develop
cracks after many miles of driving. A tire
and/or wheel could fail suddenly, causing
a crash. Use only radial-ply tires with the
wheels on your vehicle.
ProCarManuals.com

236 Car careWheel Alignment and Tire Balance
The wheels on your vehicle were aligned
and balanced carefully at the factory to give
you the longest tire life and best overall per-
formance.
Scheduled wheel alignment and wheel bal-
ancing are not needed. However, if you
notice unusual tire wear or your vehicle pull-
ing one way or the other, the alignment may
need to be reset. If you notice your vehicle
vibrating when driving on a smooth road,
your wheels may need to be rebalanced.
Wheel Replacement
Replace any wheel that is bent, cracked or
badly rusted or corroded. If wheel nuts keep
coming loose, the wheel, wheel bolts and
wheel nuts should be replaced. If the wheel
leaks air, replace it (except some aluminum
wheels, which can sometimes be repaired).
See your dealer if any of these conditions
exist.
Your dealer will know the kind of wheel you
need.
Each new wheel should have the same
load-carrying capacity, diameter, width,
offset and be mounted the same way as the
one it replaces.
If you need to replace any of your wheels,
wheel bolts or wheel nuts, replace them only
with new Saab original equipment parts.
This way, you will be sure to have the right
wheel, wheel bolts and wheel nuts for your
vehicle.
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 245.Used Replacement Wheels
WARNING
Using the wrong replacement wheels,
wheel bolts or wheel nuts on your vehicle
can be dangerous. It could affect the
braking and handling of your vehicle,
make your tires lose air and make you
lose control. You could have a collision in
which you or others could be injured.
Always use the correct wheel, wheel bolts
and wheel nuts for replacement.
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.

245 Car care
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.
