2006 SAAB 9-3 tire pressure

211 Starting and driving
For long tripsBefore starting off on a long journey, it is
advisable to have your car inspected by
your Saab dealer.
Obtain a few important items to take along
on your journey, such as spare bulbs, wiper
blades, fuses, a drive belt (poly-V-belt) and
the like.
You can check some points yourself before-
hand:
 Check that no oil or fuel leaks out of the
engine or gearbox/transmission.
 Check the coolant and power steering
fluid levels. Check also for leaks.
 Inspect the drive belt (poly-V-belt) and
replace if it shows any signs of wear.
 Check the battery charge.
 Check the tires for tread pattern and air
pressure, including the compact spare
tire.
 Take an extra remote control and keep it
separate.
 Check the brakes.
 Check all bulbs.
 Check for the presence of the tool kit and
jack in the car.93U S M 06.book Page 211 Friday, February 18, 2005 1:15 PM

254 Car careAutomatic tire pressure
monitoring3The 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.Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure
label. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or tire inflation pressure label, you
should consult the appropriate section of
this owner’s manual to determine the proper
tire inflation pressure, see page 306.) When
the low tire pressure telltale is illuminated,
one or more of your tires is significantly
underinflated.
You should stop and check your tires as
soon as possible, and inflate them to the
proper pressure. Driving on a significantly
under-inflated tire causes the tire to over-
heat and can lead to tire failure.
WARNING
The system is intended to aid the driver.
The driver is always ultimately responsi-
ble for ensuring that the tire pressure is
correct.
For optimum safety, economy and
comfort, check the tires regularly, even if
the automatic tire pressure monitoring
system has not issued an alarm
NOTICEGreat care must be taken when changing
tires so as not to damage the sensors that
are integrated in the valves.
 Remove the rear side first.
 Start removing the tire at a point oppo-
site the valve.
 Do not allow the tire removal equip-
ment to come closer than approx.
10 cm to the valve.
 Start and finish fitting approx. 4 in.
(10 cm) from the valve.
 Do not inflate the tire to above
700 kPa/100 psi.

255 Car care
Under-inflation also reduces fuel efficiency
and tire tread life, and may affect the vehi-
cle’s handling and stopping ability.
Your vehicle has also been equipped with a
TPMS malfunction telltale to indicate when
the system is not operating properly. When
the malfunction telltale is illuminated, the
system may not be able to detect or signal
low tire pressure as intended. TPMS mal-
functions may occur for a variety of reasons,
including the installation of incompatible
replacement tires on the vehicle. Always
check the TPMS malfunction telltale after
replacing one or more tires on your vehicle
to ensure that the replacement tires are
compatible with the TPMS.
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 25% or more below
highest recommended pressure (see tire
pressure label on page 267), the SID will
issue a warning as to which tire is affected.
Adjust the tire pressure as soon as possible.If the vehicle is equipped with a different
wheel size than those fitted as standard and
therefore should use a different recom-
mended highest tire pressure the owner
shall contact a workshop to have the system
recalibrated. We recommend that you
contact a Saab dealer. Low tire pressure,

256 Car careIf the tire pressure continues to drop, the
SID will issue a warning alarm when the
pressure is an additional 0.2 bar below the
first warning level.
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 or three 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.

WARNING
Poor maintained and improperly used
tires are dangerous.
 Overloading your tires can cause
overheating as a result of too much
friction. You could have an blow-out
and a serious accident. See “Loading
Your Vehicle” on page 267.
 Underinflated tires pose the same
danger as overloaded tires. The
resulting accident could cause serious
injury. Check all tires frequently to
maintain the recommended pressure.
Tire pressure should be checked
when your tires are cold.
 Overinflated tires are more likely to be
cut, punctured or broken by a sudden
impact – such as when you hit a
pothole. Keep tires at the recom-
mended pressure.
 Worn, old tires can cause accidents. If
your tread is badly worn, or if your tires
have been damaged, replace them.

257 Car care
Inflation - Tire PressureThe Tire-Loading Information label shows
the correct inflation pressures for your tires
when they’re cold. “Cold” means your vehi-
cle has been sitting for at least three hours
or driven no more than 1 mile (1.6 km).Notice:
Don’t let anyone tell you that
underinflation or overinflation is all
right. It’s not. If your tires don’t have
enough air (underinflation), you can get
the following:
Too much flexing
 Too much heat
 Tire overloading
 Bad wear
 Bad handling
 Bad fuel economy
If your tires have too much air (overinfla-
tion), you can get the following:
 Unusual wear
 Bad handling
 Rough ride
 Needless damage from road hazardsAdjust the tire pressure to match the current
load and speed of the car (see page 306).
The stated tire pressures apply to cold tires,
i.e. tires that are the same temperature as
the outside air temperature. Tire pressure
increases as the tires become warm (e.g.
during highway driving) by approximately
4 psi (28 kPa). When the temperature of the
tires changes by 50°F (10°C), the tire pres-
sure will change 2 psi (14 kPa).
Never reduce the pressure of a hot tire. If the
tires are hot when you check them, only
increase the pressure, if necessary.
High speed operation
WARNING
Driving at high speeds, 100 mph
(160 km/h) or higher, puts an additional
strain on tires.
Sustained high-speed driving causes
excessive heat build up and can cause
sudden tire failure. You could have a
crash and you or others could be killed.
Some high-speed rated tires require infla-
tion pressure adjustment for high speed
operation. When speed limits and road
conditions are such that a vehicle can be
driven at high speeds, make sure the tires
are rated for high speed operation, in
excellent condition, and set to the correct
cold tire inflation pressure for the vehicle
load.

258 Car careIf you’ll be driving at high speeds, speeds of
100 mph (160 km/h) or higher, where it is
legal, set the cold inflation pressure to the
maximum inflation pressure shown on the
tire sidewall, or to 35 psi (244 kPa), which-
ever is lower. See the example below.
When you end this high-speed driving,
return to the cold inflation pressure shown
on the Tire and Loading Information label.
See Loading Your Vehicle on page 267.
Example:
You’ll find maximum load and inflation pres-
sure molded on the tire’s sidewall, in small
letters near the rim flange. It will read some-
thing like this: Maximum load 690 kg
(1521 lbs) 300 kPa (44 psi) Max. Press
For this example, you would set the inflation
pressure for high-speed driving at 35 psi
(244 kPa).
When 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 259 and “Wheel
Replacement” on page 262 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 274.
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 273.

265 Car care
Uniform Tire Quality Grading (UTQG):
Tire manufacturers are required to grade
tires based on the performance factors:
treadwear, traction and temperature resis-
tance. For more information see “Uniform
Tire Quality Grading” on page 261.
Maximum Cold Inflation Load Limit: Max-
imum load that can be carried and the max-
imum pressure needed to support that load.
For information on recommended tire pres-
sure see “Recommended lowest tire pres-
sure, cold tires” on page 306 and “Loading
Your Vehicle” on page 267.
Tire SizeThe following illustration shows an example
of a typical passenger car tire size.
Tire Width: The three-digit number indi-
cates the tire section width in millimeters
from sidewall to sidewall.Aspect ratio: A two-digit number that indi-
cates the tire height-to-width measure-
ments. For example, if the tire size aspect
ratio is “55”, as shown in item “C” of the illus-
tration, it would mean that the tire´s sidewall
is 55% as high as it is wide.
Belt Rating: A letter code is used to indicate
the type of ply construction in the tire. The
letter “R” means radial ply construction; the
letter “D” means diagonal or bias ply con-
struction; and the letter “B” means belted-
bias ply construction.
Rim Diameter: Diameter of the wheel in
inches.
Load range: The load range represents the
load carry capacity a tire is certified to carry.
Speed Rating: The maximum speed that a
tire is certified to carry a load. Speed ratings
range from “A” to “Z”. 215/55 R 16 93 H
