When It Is Time for New TiresOne way to tell when it’s time for new tires is
to check the treadwear indicators, which will
appear when your tires have only 1/16 inch
(1.6 mm) or less of tread remaining.
You need a new tire if any of the following
statements are true:
 You can see the indicators at three or
more places around the tire.
 You can see cord or fabric showing
through the tire’s rubber.
 The tread or sidewall is cracked, cut or
snagged deep enough to show cord or
fabric.
 The tire has a bump, bulge or split.
 The tire has a puncture, cut or other
damage that can’t be repaired well
because of the size or location of the
damage.
Treadwear indicatorsThe tires incorporate wear indicators in the
form of smooth, treadless strips across the
width, which become visible when only 2/
32" (1.6 mm) of tread remains. As soon as
the indicators become visible, new tires
should be fitted without delay.
Make sure you are familiar with the legal
limit for minimum tread depth in your
country and also any regulations gov-
erning the use of winter (snow) tires.
Buying New TiresTo find out what kind and size of tires you
need, look at the Tire-Loading Information
label.
The tires installed on your vehicle when it
was new had a Tire Performance Criteria
Specification (TPC Spec) number on each
tire’s sidewall. When you get new tires, get
ones with that same TPC Spec number.
That way your vehicle will continue to have
tires that are designed to give proper endur-
ance, handling, speed rating, traction, ride
and other things during normal service on
your vehicle. If your tires have an all-season
tread design, the TPC number will be fol-
lowed by an “MS” (for mud and snow).
If you ever replace your tires with those not
having a TPC Spec number, make sure they
are the same size, load range, speed rating
and construction type (bias, bias-belted or
radial) as your original tires.
If you wish to fit other tires or wheels than
those supplied with the car, consult your
Saab dealer first as to the possibilities
available.
Wheels/tires combinations that are not
approved by Saab can negatively affect the
car’s directional stability, steering and brak-
ing in both wet and dry conditions.

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.

238 Car careTire Sidewall LabelingUseful information about a tire is molded
into it´s sidewall.
Tire size: The tire size ia a combination of
letters and numbers used to define a partic-
ular tire´s width, height, aspect ratio, con-
struction type and service description.
Department of Transportation (DOT):
The Department of Transportation (DOT)
code indicates that the tire is in compliance
with the U.S. Department of Transportation
Motor Vehicle Safety standards.
Tire Identification Number (TIN): The let-
ters and numbers following DOT code are
the Tire Identification Number (TIN). The
TIN shows the manufacturer and plant
code, tire size, and and date the tire was
manufactured. The TIN is molded onto both
sides of the tire.
Tire Ply Material: The type of cord and
number of plies in the sidewall and under
the tread.Uniform Tire Quality Grading (UTQG):
Tire manufacturers are required to grade
tires based on ee performance factors:
treadwear, traction and temperature resis-
tance. For more information see “Uniform
Tire Quality Grading” on page 235.
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 277 and “Loading
Your Vehicle” on page 240.
Tire SizeThe following illustration shows an example
of a typical passenger car tire size.
Passenger (P-Metric) Tire: The United
States version of a metric tire sizing system.
The letter “P” as the first character in the tire
size means a passenger vehicle tire engi-
neered to standards set by the U.S Tire and
Rim Association.
Tire Width: The three-digit number indi-
cates the tire section width in millimeters
from sidewall to sidewall.P215/55 R 16 93 H

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”.

240 Car careLoading Your VehicleThis is an example of what your vehicle´s
Tire-Loading Information/Certification label
might look like. It is located on the B-pillar
and shows how much weight your vehicle
may properly carry. The label tells you the
proper size, and recommended inflation
pressures the the tires on your vehicle. It
also gives you important information about
the number of people that can be in your
vehicle and the total weight that you can
carry. This weight is called the Vehicle
Capacity Weight, and includes the weight of
all occupants, cargo and all nonfactory-
installed options.
Tire Terminology and DefinitionsAir Pressure: The amount of air inside the
tire pressing outward on each square inch of
the tire. Air pressure is expressed in pounds
per square inch (psi) or kilopascal (kPa).
Accessory Weight: This means the com-
bined weight of optional accessories, for
example, automatic transmission, power
steering, power brakes, power windows,
power seats, radio and air conditioning.
Aspect Ratio: The relationship of a tire´s
height to its width.
Belt: A rubber coated layer of cords that is
located between the plies and the tread.
Cords may be made from steel or other rein-
forcecing materials.
Bias Ply Tire: A pneumatic tire in which the
ply cords that extend to the beads are laid at
alternate angles substantially less than 90
degrees to the centerline of the tread.
Cold Inflation Pressure: The amount of air
pressure in a tire, measured in pounds per
square inch (psi) or kilopascal (kPa), before
a tire har built up heat from driving. See
“Inflation - Tire Pressure” on page 231.
Curb weight: This means the weight of a
motor vehicle with standard and optional
equipment including the maximum capacity
of fuel, oil and coolant, without passengers
and cargo.DOT Markings: A code molded into the
sidewall of a tire signifying that the tire is in
compliance with the U.S. Department of
Transportation motor vehicle safety stan-
dards. The DOT code includes the Tire
Identification Number (TIN), an alphanu-
meric designator which can also indentify
the tire manufacturer, production plant,
brand and date of production.
GVWR: Gross Vehicle Weight Rating see
“Loading Your Vehicle” on page 240.
GAWR FRT: Gross Axle Weight Rating for
the front axle, see “Loading Your Vehicle”
on page 269.
GAWR RR: Gross Axle Weight Rating for
the rear axle, see “Loading Your Vehicle” on
page 240.
Intended Outboard Sidewall: The side of
an asymmetrical tire that must always face
outward when mounted on a vehicle.
Kilopascal (kPa): The metric unit forair
pressure. There are 6.9 kPa to one psi.
Light Truck (LT-Metric) Tire: A tire used
on light duty trucks and some multipurpose
passenger vehicles.
Load Index: An assigned number ranging
from 1 to 279 that corresponds to the load
carrying capacity of a tire.

Safety beltsCheck the function of the safety belts regu-
larly as follows:
 Hold the diagonal strap and pull it sharply.
The safety belt should lock and it should
not be possible to withdraw it further.
Check the anchorage points in the floor.
They must not have suffered rust damage.
If a belt is worn or has any fraying edges, it
should be replaced.
Safety belts must not come into contact with
substances such as polishes, oil or chemi-
cals. If the belts get dirty, wash them with
warm water and a detergent or have them
replaced.
WARNING
If the car is involved in a crash, the safety
belts, belt pretensioners and other asso-
ciated components must be inspected at
a Saab dealer.
Never make any alterations or repairs to
the safety belts yourself but visit a Saab
dealer.

256 Car careInadequate coolinga Check that the controls for temperature
and air distribution are correctly set; see
“Manual climate-control system” on
page 98.
b Check that the condenser (in front of the
radiator) has not become clogged with
dirt and insects.
c Make sure that the compressor drive
belt does not slip (see page 205).
d Check the fuses for the ventilation fans
and compressor (see page 224).
Maintenance The compressor drive belt should be
inspected under the regular service
program.
 Clean away dirt and insects from the
condenser and radiator to prevent clog-
ging. When washing the car, use the hose
to spray the radiator and condenser
(located in front of the radiator) from both
sides (both from the front of the car and
from inside the engine bay). Do not use a
pressure washer.
Caution: Do not hose down the radia-
tor and condenser while the engine is
hot.Other than in extremely cold weather, do not
screen the radiator, e.g. with netting, as this
will greatly diminish its cooling capacity.
 Applicable to the manual climate control
system - During cold months the air condi-
tioning should be switched on once or
twice a month and run for 5–10 minutes
during highway driving once the engine is
warm.
This action saves the gaskets in the
compressor from being spoiled. The
compressor uses a lubricant that circu-
lates with the coolant.
Note:
The A/C system cannot be switched on
when the outside temperature is below 32°F
(0°C). Turn on the A/C system when the car
is standing in a warm place. Simplest is to
always have the A/C button pressed in. The
A/C system will then cut in automatically
when the outside temperature is high
enough.NOTICEDo not use a pressure washer when
cleaning the condenser or radiator due to
the risk of damage.

266 Customer Assistance and InformationVehicle Data Collection and Event
Data RecorderYour vehicle, like other modern motor vehi-
cles, has a number of sophisticated com-
puter systems that monitor and control sev-
eral aspects of the vehicle’s performance.
Your vehicle uses on-board vehicle comput-
ers to monitor emission control components
to optimize fuel economy, to monitor condi-
tions for airbag deployment, to provide anti-
lock braking and to help the driver control
the vehicle in difficult driving situations.
Some information may be stored during reg-
ular operations to facilitate repair of
detected malfunctions; other information is
stored only in a crash or near crash event by
computer systems commonly called event
data recorder (EDR).
In a crash or near crash event, computer
systems, such as the Airbag Sensing and
Diagnostic Module (SDM) in your vehicle
may record information about the condition
of the vehicle and how it was operated, such
as engine speed, throttle position, vehicle
speed, seat belt usage, airbag readiness,
airbag performance data, and the severity
of a collision. These data have been used to
improve vehicle crash performance and
may be used to improve crash performance
of future vehicles and driving safety. These
on-board systems are somewhat like the
data recorders on many airplanes, but they
do not record sounds, such as conversation
of vehicle occupants.To read this information, special equipment
is needed and access to the vehicle or the
SDM is required. Saab will not access infor-
mation about a crash event or share it with
others other than
(a) with the consent of the vehicle owner or,
if the vehicle is leased, with the consent of
the lessee,
(b) in response to an official request of
police or similar government office,
(c) as part of Saab’s defense of litigation
through the discovery process, or
(d) as required by law.
In addition, once Saab collects or receives
data, Saab may
(a) use the data for research needs,
(b) make it available for research where
appropriate confidentiality is to be main-
tained and need is shown, or
(c) share summary data which is not tied to
a specific vehicle with non-Saab organiza-
tions for research purposes.
Others, such as law enforcement, may have
access to the special equipment that can
read the information if they have access to
the vehicle or SDM.
Please check the OnStar subscription ser-
vice agreement or manual for information
on its operations and data collection.
