flat tire SAAB 9-3 2003 Owners Manual

75 Instruments and controls
Turn signal & lane change indicatorsThe stalk switch has an intermediate,
spring-loaded position that is useful for sig-
nalling when changing lanes or passing.
The stalk switch also has fixed positions for
indicating a right or left turn, that are can-
celled automatically when the steering
wheel is centered.If an indicator bulb breaks, the frequency
with which the indicators flash will be
doubled.
This frequency is also doubled if a trailer is
being towed and one of its indicator bulbs
breaks.
Hazard warning lightsThe button for the hazard warning lights is
located on the climate control panel.
When the button is pressed, all the direction
indicators and the symbol in the button flash
simultaneously.
If an indicator bulb breaks, the frequency
with which the indicators flash will be
doubled.
Hazard warning lights should only be used
if, because of an accident or breakdown, the
car constitutes a hazard to other road users.
WARNING
Switch on the hazard flashers if the car
has to be left at the roadside on account
of a crash, engine trouble or a flat tire.
If you carry a warning triangle or flares,
they should be set up along the side of the
road 50–110 yds. (50–100 metres)
behind your vehicle. If the car is not
clearly visible (e.g. over the brow of a hill
or bridge), place the triangle/flare even
further back.

122 Starting and drivingIgnition switchThe ignition switch is located on the center
console between the front seats. In cars
with automatic transmission, the remote
control can only be removed when the
selector lever is in position P.NOTICETake care not to spill drinks or to drop
crumbs over the ignition switch. If dirt or
liquid gets into it, the switch may not
operate properly.
WARNING
• Always remove the remote control
before leaving children unattended in
the car.
 Apply the parking brake before remov-
ing the remote control.
 Never remove the remote control
while the car is moving. This will acti-
vate the steering wheel lock and make
it impossible to steer the car.
LOCK position
The position lights, hazard warning lights and interior lighting can be
turned on.
Cars with automatic transmission: Move the gear lever to P.
The gear lever is locked in position. This is the only position in which the
remote control can be removed.
Cars with manual transmission: The remote control can be removed
regardless of the position of the gear lever.
OFF position
Parts of the electrical system are operative.
Do not leave the remote control in the OFF position with the engine
not running as this could cause the battery to run flat in a matter of
hours.
Cars with automatic transmission: The gear lever is not locked. See
also page 135.
ON position
The entire electrical system is operative.
Do not leave the remote control in the ON position when the engine
is not running.
Turn the remote control to the OFF position to disconnect the electrical
system.
When you turn the remote control to ON, some indicator and warning lights
will come on in the main instrument panel. These should go out after about
3 seconds.
ST - starter position
The starter motor operates (automatic transmission: selector lever must
be in P or N) when the remote control is turned to this position. When
released, the remote control will spring back to the ON position.
The car has an electronic restart lock. If the engine fails to start, the remote
control must first be turned back to a position between OFF and LOCK
before the starter motor can be operated again.

162 Starting and drivingDriving with a loadThe handling characteristics are affected by
how the car is loaded.
 Place the heaviest load as far forward and
as low as possible in the trunk.
 Secure the load to the lashing eyes (see
page 118).
 Heavy loads mean that the car’s center of
gravity is further back. As a result, the car
will sway more during evasive steering.
 Never exceed the permissible load of the
roof box, even if there is room for more.
 Ensure that the tire pressure is correct –
slight overinflation is preferable to under-
inflation.
 The braking distance of a loaded car is
always greater. Keep your distance from
the vehicle in front.
 Do not exceed the car’s permissible
gross vehicle weight or axle load (see
page 236).
 Roof loads can negatively affect telecom-
munication.
TiresNote: Low tire pressure also causes prema-
ture tire wear and increased fuel consump-
tion.
Tire pressure should match the current load
and speed of the car (see page 245).
The tire pressures given apply to cold tires,
that is tires that are the same temperature
as the outside air temperature.
The tire pressure increases approximately
4 psi/27 kPa as the tires become warm (e.g.
during highway driving). When the temper-
ature of the tires changes by 50°F (10°C),
the tire pressure will change 2 psi/13 kPa.Never reduce the pressure of a hot tire. If the
tires are hot when you check them, only
increase the pressure, if necessary.
Underinflated tires wear more quickly than
slightly overinflated tires.
If a valve is leaking, simply unscrew it and fit
a new one.
Note: Remember to adjust the tire pres-
sures if you change the load in the car sig-
nificantly or intend to drive at substantially
lower or higher speeds than normal.
Automatic tire pressure monitoring, see
page 207.
WARNING
Check the tire pressure at least once a
month and before long journeys. Under-
inflation can result in:
 punctures
 separation of the tire and tread
 damage to the sidewalls
 damage to the rims on poor roads
 poor handling characteristics
 premature tire wear
 increased fuel consumption.

207 Car care
Tire pressure
Note: Low tire pressure also causes prema-
ture tire wear and increased fuel consump-
tion.
Adjust the tire pressure to match the current
load and speed of the car (see page 245).
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
0.3 bar (4 psi). When the temperature of the
tires changes by 50°F (10°C), the tire pres-
sure will change 0.1 bar (2 psi).
Never reduce the pressure of a hot tire. If the
tires are hot when you check them, only
increase the pressure, if necessary.
Soft tires will cause faster wear than over-
pressurized tires.
If a valve is leaking, simply unscrew it and fit
a new one.
Note: Remember to adjust the tire pressure
if you change the load in the car or intend to
cruise at a speed that is substantially differ-
ent from normal.
Automatic tire pressure monitoring(option, certain variants only)
The pressure monitoring system consists of
a sensor in each wheel, a detector in each
wheel housing and a receiver. The sensors
are located inside the wheels directly adja-
cent to the air valves.
WARNING
Check the tire pressure at least once a
month and before long journeys. Under-
inflation can result in:
 punctures
 separation of the tire and tread
 damage to the sidewalls
 damage to the rims on poor roads
 poor handling characteristics.
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.
ProCarManuals.com

208 Car careThe receiver is located in the trunk. 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.If 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. Tire pressure low,
front left.
Check tires.
Flat tire front left.
Make a safe stop.

209 Car care
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.
Shifting the wheelsBecause 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.
The wheels should be marked, L (left) and
R (right), when changing between summer
and winter (snow) tires. This ensures that
the direction of rotation of the wheels is the
same when they are refitted. Fit the tires in
best condition to the rear wheels.
Store wheels lying flat or hanging – never
standing upright.
Tire markingsAn example of the meaning of the different
markings in a tire size is given below for a
tire size of 195/65 R15 91H: Tire pressure
system failure.
Contact Saab dealer.
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.
Always move rear left to front left and rear
right to front right, so that the direction of
rotation remains the same.

TemperatureThe 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. Excessive temperature
can lead to sudden tire failure. The grade C
corresponds to a level of performance
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.
Wear 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.
WARNING
The temperature grade for a tire is estab-
lished for a tire that is properly inflated
and not overloaded. Excessive speed,
underinflation, or excessive loading,
either separately or in combination, can
cause heat buildup and possible tire fail-
ure.

213 Car care
The spare wheel, the tools and the jack with
its crank are carried under a panel in the
trunk.
Fold the carpeting forward to ease access to
the tools and spare wheel.
The screwdriver handle has a "button" for
removing plastic rivets. This type of rivet
must be removed when changing the light
bulb in the trunk lid (see page 195).Your Saab is equipped with a trip computer
and you can use its "Speed warning" func-
tion, to monitor driving speed since you
must not exceed 50 mph (80 km/h).
NOTICETo avoid damaging an alloy wheel with a
flat tire, this can be placed outside up in
the spare-wheel well but only while driv-
ing to the closest workshop.
A general rule is that all heavy loads must
be well secured in the luggage compart-
ment (see page 118).

215 Car care
When the car has to be lifted, the jack must
be positioned at one of the four jacking
points (front or rear) under the sill members.
If a floor jack is used, the lifting plate must
be positioned under the normal jacking
points. If the car is equipped with a towbar,
the jack can also be placed under this.
1 Apply the parking brake and engage 1st
or reverse gear (automatic transmis-
sion: select P).
2 Wind the jack up to a suitable height
before placing it under the jacking point.
Each jacking point is indicated by an arrow on the sill (see illustration).
Make sure that the jack fully engages
the jacking point in the underside of the
sill member and that the entire foot of the
jack is steady and flat on the ground.
The jack must not stand on snow, ice or
similar.
Wind up the jack until it just begins to lift
the car.
3 It is not necessary to remove the wheel
cover.
If, none the less, you wish to remove the
wheel cover, take hold of the outer edge
and pull it straight out.
Loosen the wheel bolts half a turn.
4 Wind the jack to raise the wheel clear of
the ground. Remove the wheel bolts and
lift off the wheel.5 Clean any rust or dirt from the contact
surfaces between the wheel and brake
disc. Do not wipe away the grease in the
wheel hub.
6 Fit the wheel and screw in the bolts in the
sequence shown on the following page
(opposite pairs).
Tighten the bolts enough for the bolts
and wheel to be seated correctly.
7 Lower the car and tighten the wheel
bolts to torque in sequence as shown on
the following page.
Tightening torque:
Light-alloy wheels: 110 Nm.
Steel wheels: 110 Nm.NOTICEApply the jack only to the jacking points
indicated on the body.

217 Car care
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.
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.
Upholstery and trimTo remove fluff and hairs from the seats,
door armrests and headlining, use a
vacuum cleaner, a moist lint-free cloth, or a
clothes brush. Remove spots and dirt using
a cloth moistened with lukewarm soapy
water.
When using a stain remover, always work
from the outside towards the centre to avoid
leaving a ring. If a soiled ring or spot should
remain, it can usually be removed using
lukewarm soapy water or water alone.
Spots left by liquids, such as soft drinks or
thin oil, must be removed at once with an
absorbent material, such as kitchen towel-
ling. Then clean with a stain remover.
White spirit is recommended for removing
grease and oil stains. A medium stiff brush
may also be used.
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 safetybelts yourself but visit a Saab
dealer.
