Scrapping or working on airbag and
belt pretensioners Frequently asked questions on func-
tion of the airbag
Do you still need to wear a
safety b
elt if air-
bags are fitted?
Yes, always! The airbag merely supple-
ments the car’s normal safety system.
Moreover, the airbag will only be actuated in
a moderate to severe frontal, or near-frontal
collision, which means, of course, that it pro-
vides no protection in minor frontal colli-
sions, major rear-end or side-on collisions
or if the car rolls over.
The safety belts help reduce the chance of
the car occupants from being thrown around
and injured inside the car.
But they also ensure that, if a collision
occurs in which the airbags are inflated, the
airbag will make the optimum contact with
the occupant, i.e. square on from the front.
If the occupant meets the airbag in an offset
position, the protection afforded will be
reduced.
In addition, airbags provide no protection
against a secondary impact occurring in the
same incident. So there is no doubt about
the benefit of wearing safety belts at all
times.
Do not sit too close to the airbag: it needs
room to inflate.
The airbag inflates very quickly and power-
fully in order to protect an adult person in a
serious frontal collision.
How do I position the seat to leave room for
the airbag to inflate?Don’t have your seat too far forward.
Recline the seat back to increase the dis-
tance between you and the airbag. For short
drivers, special accessory pedal extensions
are available through your Saab dealer.
Airbags inflate extremely rapidly and with
great force - to be fast enough to protect an
adult in the seat. When does the airbag inflate? The airbag will only be inflated under certain
predetermined conditions in a moderate to
severe frontal, or near-frontal collision,
depending on such factors as the force and
angle of the impact, the speed of the car on
impact, and the resistance to deformation of
the impacting object.
The airbag can only be activated once in the
same incident.
Do not attempt to drive the car after an
airbag has been inflated, even if it is possi-
ble. What won’t trigger the airbag? The airbag will not be activated in all
front-end collisions. For instance, if the car
has hit something relatively soft and yielding
(e.g. a snow drift or a hedge) or a solid
object at a low impact speed, the airbag will
not necessarily be triggered.
WARNING
 Under no circumstances should any
modifications be made that affect the
steering wheel or the airbag’s electri-
cal circuitry.
 Before starting any welding work on
the car, always disconnect the nega-
tive (–) battery lead and cover the con-
ductor.
 Airbags and belt pretensioners must
be deployed under controlled condi-
tions before the car is scrapped or any
of the system’s components are
removed. Airbags or belt pretension-
ers that have been deployed as a
result of an accident must be replaced
by new ones.
 Airbag-system components must
never be transferred for use in another
vehicle.
 All work involving the scrapping or
replacement of airbags or belt preten-
sioners must only be carried out by
knowledgeable personnel.

27 Safety
Side airbagSide airbags are housed inside the back-
rests of the front seats and are designed to
protect the driver and front passenger in the
event of a side impact.
In a side impact, only the airbag on that side
will be activated, and only then if certain pre-
determined conditions are met such as the
force and angle of the impact, the speed of
the car on impact, and at which point on the
car’s side the impact occurs.
The sensors, which are fitted in the front
doors, sense the rise in pressure caused by
the door panel being pressed in during an
impact condition. The side airbag trigger will
be commanded based on the characteris-
tics of this pressure rise.
WARNING
 This car is equipped with side airbags
and no extra interior trim should be fit-
ted. Failure to observe this warning
could result in the side airbags not
inflating as intended and thus not pro-
viding the intended protection either.
 Never place any object in the area that
would be occupied by the inflated air-
bag.
 For optimum protection, sit upright in
the seat, with your safety belt correctly
fastened.
 The sensors for the side airbags are
fitted in the doors.
 We advise against doing any work on
the doors that could affect the mois-
ture barrier in the door or the airbag
sensors. It is essential that the mois-
ture barrier (thick plastic film) in the
door is not damaged in any way.
 Improvement of the anticorrosion
treatment of the doors should only be
carried out by an authorized Saab
dealer. Otherwise there is a risk that
the side impact sensor and the mois-
ture barrier in the door could be dam-
aged.
 The side airbags will inflate only in the
event of a side impact; not in the event
of a front or rear-end collision or of the
car’s rolling over.
 Damage to the seat cover, or the seat
seam, in the area of the side airbag
must immediately be repaired by an
authorized Saab dealer.
 Do not modify the speaker installation
in the front doors or install speakers
other than those specifically approved
by Saab.

57 Instruments and controls
Central warning light
This light comes on and a chime will sound
if a fault has been detected in any system
that is critical to safety. Any of the following
can activate the central warning light and
alarm:
 Airbag system.
 Low oil pressure in engine.
 Parking brake is on (when car is moving).
 Brake fluid level low.
 Fault detected in ABS system.
 Engine overheating.
 Alternator not charging properly.
The symbol and the chime will also sound if
the ignition key is turned to the ON position
but the engine is not started within 10 sec-
onds.
Cruise Control
indicator light
The symbol is lit when cruise control is
active.
Engine malfunction
(CHECK ENGINE)
This light indicates a malfunction in the
fuel-injection or ignition system. The car
may still be driven with care and with some-
what diminished performance.
SPORT Mode Indicator
On cars with automatic transmission the
indicator light comes on when you press the
SPORT button on the gear-lever knob.
In SPORT mode, the transmission remains
longer in the (D, 3, 2, 1) gears before
upshifting.
Quit Sport mode by again depressing the
SPORT button; see also page 147.
WINTER Mode Indicator
On cars with automatic transmission the
indicator light comes on when, in the D posi-
tion, you press the WINTER button on the
center console next to the gear selector.
When the car is in the Winter mode it starts
in 3rd gear, which gives a better grip in
slippery conditions by reducing the ten-
dency to spin the wheels.
Quit Winter mode by again depressing the
WINTER button; see also page 147.
WARNING
An illuminated CHECK ENGINE indicator
light indicates a serious engine-related
problem. While your car may be able to be
driven with the CHECK ENGINE indicator
light illuminated (limp-home mode), you
are advised to have your car serviced at
an authorized Saab dealer as soon as
possible.
Continued driving without this problem
being corrected might cause serious fur-
ther damage to your car and create
unsafe driving conditions. The operator
should be prepared to take action if such
unsafe conditions arise (e.g., apply the
brakes, disengage transmission, turn off
the ignition etc.).

76 Instruments and controlsManual climate-control
systemThe air is drawn in through an intake at the
bottom edge of the windshield. It passes
through an efficient filter before being
routed through the climate-control system
and into the cabin. The cabin discharge vent
is located on the right behind the rear
bumper. The air discharge vents should be
kept free of snow and ice in the winter.
The rate of air flow inside the car is con-
trolled by means of the fan switch. Temperature control The temperature of the incoming air can
be steplessly varied using the temperature
control.
Air distribution The air distribution control is used to direct
the flow of air to the defroster, dash and floor
vents.
The control permits settings intermediately
between the three main settings so that the
available air can be apportioned between
the floor and the windshield (defroster) or
between the floor and the panel.
To counter cold drafts from the front side
windows when the control has been set to
defroster or floor, a small flow of air issues
from the dash vents. The dash vents swivel universally, so that
the air can be directed as desired.
The flow of air through the dash vents can
be adjusted for each vent by means of the
adjacent control.
Air to the rear side windows is supplied by
the floor ducts. To demist these windows
you should therefore select a defroster/floor
combination.
If the windows are thoroughly cleaned it is
much easier to keep them free of mist.

78 Instruments and controls
The air conditioning is combined with the
conventional climate-control system and is
switched on by pressing the button,
provided that the fan control is in
position 1-4.
The incoming air is treated in three stages:
first it passes through a filter; it is then dehu-
midified and cooled and, finally, if required,
heated.
The air conditioning can be used at outdoor
temperatures down to 32°F (0°C). Condensation water When the A/C compressor is on, the incom-
ing air is dehumidified. The resulting con-
densation water is drained away through an
outlet under the car.
It is therefore perfectly normal for water to
be seen dripping from this outlet when the
car is parked. The warmer the ambient air
and the higher the humidity, the more con-
densation will form. When the button is depressed the
regular air intake will be closed. In this posi-
tion, the air inside the cabin is recirculated.
Use recirculation when you want rapid cool-
ing, at extremely high air temperatures.
Switch the air conditioning (A/C) on first.
Recirculation can be useful to activate man-
ually to prevent unpleasant smells being
drawn into the car from outside.
Note that recirculation should not be
used when the outside temperature is
lower than 50°F (+10°C) except briefly,
e.g. to avoid unpleasant air from enter-
ing the car. Prolonged use of recircula-
tion could cause the windows to mist or
ice up.

136 Starting and drivingUseful tips on cold climate startingIf the engine has failed to start after several
attempts in very cold weather, press and
hold the accelerator down to the floor and
run the starter for 5–10 seconds. This will
prevent the engine being flooded (exces-
sively rich fuel-air mixture).
Now start the engine in the normal way – do
not touch the accelerator.
If the engine stalls immediately after starting
(e.g. if the clutch was released too quickly),
do not touch the accelerator when restarting
the engine.
Every time the engine is switched off the
spark plugs are automatically cleaned. If
your attempt to start nevertheless fails, let
go of the ignition key and allow it to spring
back. This initiates more vigorous cleaning
of the sparking plugs which goes on for
about 5 seconds. Then start in the ordinary
way. Do not touch the accelerator; if the
accelerator is pressed to the floor the fuel
supply is shut off.
Important
considerations for
drivingThe engine-management system in the
Saab 9-3 is called Saab Trionic T7. The
system manages the ignition, fuel injection
and turbo boost pressure.
The Trionic T7 system developed by Saab
is an intelligent engine-management
system designed to achieve optimum drive-
ability under differing driving conditions.
The system makes adjustments automati-
cally, for instance, if the car is being driven
at altitude (oxygen-deficient air), for differ-
ent grades of fuel (AON 87–93) and for dif-
ferent load conditions.
1 Starting and driving
 Refrain from using full throttle before
the engine has warmed up (before
needle is in the mid-range on tempera-
ture gauge) to avoid unnecessary
wear. If the needle of the pressure
gauge repeatedly enters the red zone
the engine may suddenly lose power,
owing to the intervention of a monitor-
ing system which curtails the charging
pressure. Get in touch with an autho-
rized Saab dealer at once.
 A safety function prevents the engine
from revving faster than 6,200 rpm by
temporarily shutting of the fuel injec-
tors.2 Stopping the engine
 Do not rev the engine immediately
before switching it off - stop the engine
when it is idling.
3 Regulating the charging pressure
 The system is optimized for fuel with an
octane rating of AON 90. For cars with
205 hp engines and the Viggen, the
system is optimized for AON 93. One of
the advantages of the system is that it
enables the engine to be run safely on
lower-grade fuel, although not lower
than AON 87. However, engine perfor-
mance will fall off slightly, and heavy
loading should be avoided. For best
performance you should use the rec-
ommended grade of fuel, AON 90
(205 hp engine and Viggen AON 93).
 The maximum boost pressure is
adjusted automatically to the knocking
or pinging tendency of the engine.
Occasional, short-lived knocking when
the engine is under a heavy load is per-
fectly normal; the extent will depend on
the grade of fuel in the tank.
 Isolated instances of knocking are
more likely to occur with low-octane
fuel. This controlled form of knocking,
followed by a reduction in the boost
pressure, is a sign that the wastegate is
functioning and is perfectly safe for the
engine.

138 Starting and drivingStop jump-starting if the engine fails to
start immediately.
 Failure to follow these directions could
result in the catalytic converter and asso-
ciated components being damaged, and
could represent a breach of the warranty
conditions.
RefuelingEnsure that you are using the correct grade
of fuel, unleaded AON 87-93. For optimum
performance we recommend:
AO N 90 for 2.0 Turbo 185 hp.
AO N 93 for 2.0 Turbo 205 hp and
2.3 Turbo Viggen.
If fuel containing a mixture of alcohol is
used, the following restrictions apply:
Methanol: max. 5% by volume.
Ethanol: max. 10% by volume.
MTBE: max. 15% by volume.
The fuel filler cap is located in the right rear
quarter panel.
Switch off engine.
Insert the fuel-pump nozzle beyond the
flange on the filler pipe. Do not withdraw the
nozzle while filling is in progress.
Cease refuelling the first time the pump
stops.
Fuel-tank capacity: 17.0 US gal. (64 liters)
Screw on the filler cap and keep turning until
it has clicked at least three times.
Manually opening the fuel filler door, see
page 131, Convertible, page 52.The most effective way to prevent conden-
sation forming in the tank (and thus avoid
possible running problems) is to keep the
tank well filled.
Before the onset of freezing temperatures in
winter, it may be advisable to add gasoline
anti-freeze to the fuel a few times to dispel
any condensation in the system.
NOTEIf the car runs out of fuel, it is possible for
air to get into the fuel system. If this
happens, the catalytic converter may
overheat and be damaged.
NOTEDo not overfill. Fuel should not come right
up the filler pipe as expansion room is
needed.
WARNING
 Never use fuel for any purpose other
than as engine fuel.
 Gasoline is highly flammable and can
cause severe burns. Never use an
exposed flame in the vicinity of gaso-
line. Never smoke when filling the
vehicle up with gasoline.
