156 Starting and drivingESP indicator lightThe indicator light in the tachometer
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.ESP OFFThe light in the rev counter comes on
if:
 A fault has been detected and the system
has therefore been switched off.
 The system has been switched off manu-
ally.
 When the ignition key is turned to the ON
position, the lamp is lit for about four
seconds while the system undergoes a
self-test.
Turning ESP offThe system can be turned off manually with
the ESP button, whereupon the light
on the main instrument panel will come on.
The ESP system cannot be switched off if
the car is travelling faster than 35 mph
(60 km/h).
The ESP is always operative during brak-
ing, even if it has been switched off manu-
ally.NOTICESuspension modifications, such as
changing the type of wheels, dampers or
springs, can affect the function of the ESP
system.
Always consult a Saab dealer before
changing any suspension components.

159 Starting and driving
Engine block heater(standard equipment in Canada, acces-
sory in U.S.)The following are just some of the benefits
to the car and the environment of using an
engine block heater:
 Lower fuel consumption.
 Exhaust emissions substantially reduced
over short runs.
 Reduced wear on the engine.
 Inside of car warms up faster.
The engine heater is effective at outside
temperatures up to +15–20°C. The warmer
it is outside, the shorter the time the engine
heater needs to be connected. Longer than
1.5 hours is unnecessary.
If the car is equipped with a removable,
electrical cabin heater that is not in use, this
should be stored in the luggage compart-
ment.
Driving in cold weatherBefore starting a journey in cold weather
you should check the following:
 That the wiper blades have not become
frozen to the windshield/glass.
 Brush any snow away from the air intake
for the heater system (opening between
hood and windshield).
 It may be advisable to lubricate the door-
lock cylinder (use molybdenum
disulphide, MoS
2) to prevent its freezing.
If the lock has frozen, take care not to
break the key (or use the remote control)
– heat it first or spray it with de-icer.
 Periodically during the winter, add gaso-
line anti-freeze to the fuel to dispel any
condensation in the fuel tank which could
freeze and cause problems in the system.
Keep the tank well filled to reduce the risk
of condensation forming.
If the car is parked outside in freezing
weather, fuel additives (gasoline anti-
freeze) will not do any good as it cannot
remove water that has already frozen.
Park the car in a warm place so that any
ice that may have built up melts, then add
gasoline anti-freeze when filling up the
tank. Condensation is caused by changes
in the outdoor temperature or by the car
being parked alternately in a garage and
outside.
 It is particularly important when the roads
are slippery that the brakes and tires be in
good condition. Check the anti-freeze in the engine coo-
lant, see page 188.
The car´s trip computer will warn you when
there is a risk of slippery conditions. For fur-
ther information on this function, see
page 62.
The car is equipped with tires designed to
provide optimum grip on both wet and dry
roads, although this has been achieved at
the expense of somewhat reduced grip on
snow and ice. For regular driving on snow
and ice, we therefore recommend that
winter (snow) tires be fitted.
Winter (snow) tires, particularly studded
tires (where use is legally permitted), gener-
ally make driving safer on snow and ice.
Acquaint yourself with the legal provi-
sions governing the use of different
types of winter tires and snow chains.
Studded tires are not allowed in some
countries
.

160 Starting and drivingIf winter tires are fitted, the same type must
be fitted on all wheels. Your Saab dealer will
be pleased to advise you on the best tires for
your car.
Remember that tires age. It may therefore
be necessary to change them before they
reach the legal wear limit, as they gradually
lose their friction properties.
The best response if the car gets into a front-
wheel skid is to freewheel (manual gearbox
only), i.e. disengage the clutch (so that the
wheels are neither driven or retarded by the
engine.
If the car has automatic transmission, ease
up on the accelerator and steer carefully in
the desired direction.
In a rear-wheel skid, steer in the same direc-
tion that the rear of the car is moving.
Tire chainsIf you want to fit tire chains (where legally
permitted) they should only be fitted to the
tires recommended under ”Specifications”
(see page 260).
Consult your Saab dealer for details of
approved tire chains.
Driving in hot weather Always check the coolant level before
starting a journey. The level should be just
below the MAX mark.
 At the end of a journey, if the engine has
worked hard, allow it to idle for two or
three minutes before switching it off.
If the needle on the temperature gauge
enters the red zone:
1 Bring the car to a standstill but leave the
engine running. Do
not
remove the cap
on the expansion tank even if the tank is
empty. If the needle on the temperature
gauge continues to rise while the engine
is idling, switch off the engine.
WARNING
 Do not exceed 30 mph (50 km/h)
when tire chains are fitted.
 Tire chains can reduce the directional
stability of the car.
 Tire chains must not be used on the
rear wheels. NOTICE Check the links frequently for wear.
 Check that the chains do not contact
the wheel-arch liner at full lock.
 See section ”Specifications”,
page 260, for information on allowable
wheel dimensions for the fitting of tire
chains.

218 Car care and technical informationWhen 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 gauge to
check tire pressure. You can’t tell if your
tires are properly inflated simply by looking
at them. Radial tires may look properly infla-
ted 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 RotationAny 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 219 and “Wheel Repla-
cement” on page 222 for more information.
The purpose of regular rotation is to achieve
more uniform wear for all tires on the
vehicle. The first rotation is the most impor-
tant.
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 tigh-
tened. See page 233.
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
balancing.
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 wheel” on
page 231.

220 Car care and technical informationThe wheels and tires have been carefully
matched to the characteristics of the car and
play a key role in its outstanding roadhol-
ding 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 wheels and tires on your
Saab.
Wide wheels and tires with sidewalls that
are too low can:
 be damaged in potholes etc.
 cause springs, shock absorbers and
wheel bearings and body mountings
can be overloaded.
 cause the wheels to come into contact
with chassis and body components.
 can affect the function of the Elec-
tronic Stability Program (ESP).
The speed and load limits for the tires
must not be exceeded; see page 225.
Wheels larger than 17” must not be fitted.
The maximum permissible offset is
49 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 230.
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.

221 Car care and technical information
Uniform Tire Quality GradingQuality grades can be found where applica-
ble on the tire sidewall between tread shoul-
der and maximum section width. For
example:Treadwear 200 Traction AA
Temperature AThe following information relates to the
system developed by the United States
National Highway Traffic Safety Administra-
tion, which grades tires by treadwear, trac-
tion and temperature performance. (This
applies only to vehicles sold in the United
States.) The grades are molded on the side-
walls of most passenger car tires. The Uni-
form Tire Quality Grading system does not
apply to deep tread, winter-type snow tires,
space-saver or temporary use spare tires,
tires with nominal rim diameters of 10 to 12
inches (25 to 30 cm), or to some limited-pro-
duction tires.
While the tires available on General Motors
passenger cars and light trucks may vary
with respect to these grades, they must also
conform to federal safety requirements and
additional General Motors Tire Perfor-
mance Criteria (TPC) standards.
TreadwearThe treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions on
a specified government test course. For
example, a tire graded 150 would wear one
and a half (1.5) times as well on the govern-
ment course as a tire graded 100. The rela-
tive performance of tires depends upon the
actual conditions of their use, however, and
may depart significantly from the norm due
to variations in driving habits, service prac-
tices and differences in road characteristics
and climate.Traction – AA, A, B, CThe traction grades, from highest to lowest,
are AA, A, B, and C. Those grades repre-
sent the tire’s ability to stop on wet pave-
ment as measured under controlled condi-
tions on specified government test surfaces
of asphalt and concrete. A tire marked C
may have poor traction performance. War-
ning: The traction grade assigned to this tire
is based on straight-ahead braking traction
tests, and does not include acceleration,
cornering, hydroplaning, or peak traction
characteristics.
Temperature – A, B, CThe temperature grades are A (the highest),
B, and C, representing the tire’s resistance
to the generation of heat and its ability to dis-
sipate heat when tested under controlled
conditions on a specified indoor laboratory
test wheel. Sustained high temperature can
cause the material of the tire to degenerate
and reduce tire life, and excessive tempera-
ture can lead to sudden tire failure. The
grade C corresponds to a level of perfor-
mance which all passenger car tires must
meet under the Federal Motor Vehicle
Safety Standard No. 109. Grades B and A
represent higher levels of performance on
the laboratory test wheel than the minimum
required by law.
Warning: The temperature grade for this tire
is established for a tire that is properly infla-
ted and not overloaded. Excessive speed,
underinflation, or excessive loading, either
separately or in combination, can cause
heat buildup and possible tire failure.

Tire Chains
Notice:
If your vehicle does not have
225/45R17 size tires, use tire chains only
where legal and only when you must.
Contact your Saab dealer regarding sui-
table snow chains. Install them on the
front tires and tighten them as tightly as
possible with the ends securely faste-
ned. 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. Dri-
ving too fast or spinning the wheels with
chains on will damage your vehicle.If a Tire Goes Flat
It’s unusual for a tire to “blow-out” 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 “blow-out”, 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 blow-out, 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 accele-
rator 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 225/45 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.
