29 Safety
Airbag The AIRBAG system comprises an airbag in
the steering wheel, a front passenger airbag
and side airbags in the front seats.
The system supplements the protection
provided by the safety belts to further
enhance the safety of the occupants.
If a fault is detected in the AIRBAG, the
AIR BAG warning light on the main instru-
ment panel will come on (see pages 61
and 37). When the system is triggered by impact of a
frontal crash, the airbags in the steering
wheel and passenger side of the dash board
are inflated, after which they deflate through
vents in the back of the bags.
The entire process takes less than
0.1 second – literally, faster than the blink-
ing of an eye.
The driver and passenger airbags are
referred to as ‘smart’ airbags. This means
that the system compensates for factors
such as the force of the collision.Note:
The sensor reacts differently depending on
whether or not the front seatbelts on the
driver’s and passenger sides are used. Sit-
uations can therefore arise where only one
of the airbags inflates.
It is also possible for only the seatbelt pre-
tensioners to be activated and for the air-
bags to remain uninflated.
These airbags are triggered only by moder-
ate to severe frontal or near-frontal crashes.
They will not be activated by minor front-end
impacts, rear-end or side impacts, or by the
car rolling over.
WARNING
To reduce risk of injury:
Always wear your safety belt.
Always adjust your seat so that you
are as far back as possible but still
able to operate the pedals and reach
the steering wheel and controls com-
fortably.
Children 12 and under or shorter than
59 inches (150 cm) should always
travel in the rear seat as the car is fitted
with a passenger airbag.
Never fit a child seat in front of the pas-
senger airbag.

33 Safety
Passenger Sensing SystemVehicles with a passenger sensing system
have indicator LEDs on the fascia. The indi-
cators will be lit during the system check
when you turn your ignition key to ST or ON.
When the system check is complete, either
the ON or the OFF LED, will be lit. See
AIRBAG warning light on page 61.
The passenger sensing system will turn off
the right front passenger’s frontal airbag
and side airbag under certain conditions.
The driver’s airbags is not part of the pas-
senger sensing system.
The passenger sensing system works with
sensors that are part of the right front pas-
senger’s seat and safety belt. The sensors
are designed to detect the presence of a
properly-seated occupant and determine if
the passenger’s frontal airbag should be
enabled (may inflate) or not.
Accident statistics show that children are
safer if they are restrained in the rear rather
than the front seat.Saab recommends that child restraints be
secured in a rear seat, including an infant
riding in a rear-facing infant seat, a child
riding in a forward-facing child seat and an
older child riding in a booster seat.
Your vehicle has a rear seat that will accom-
modate a rear-facing child restraint. A label
on your sun visor says, “Never put a
rear-facing child seat in the front.” This is
because the risk to the rear-facing child is so
great, if the airbag deploys.

36 SafetySide airbags
The side airbags, which help protect the
upper body are integrated in the outside
edges of the front seat backrests.
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 front doors. We advise
against doing any work on the doors
that could affect the moisture barrier in
the door or the airbag sensors. It is
essential that the moisture barrier
(thick plastic film) in the front door is
not damaged in any way.
Improvement of the anticorrosion
treatment of the doors should only be
carried out by a workshop. We recom-
mend that you contact an authorized
Saab dealer. Otherwise there is a risk
that the side impact sensor and the
moisture barrier in the front door could
be damaged.
The side airbags will inflate only in the
event of a side impact; not in the event
of a front or rear-end crash or of the
car’s rolling over.
Damage or wear to the seat cover, or
the seat seam, in the area of the side
airbag must immediately be repaired.
We recommend that you contact an
authorized Saab dealer.
Do not modify the speaker installation
in the front doors or install speakers
other than those specifically approved
by Saab.

65 Instruments and controls
Speedometer(U.S. speedometer shown)
The speedometer receives signals from the
wheel sensors in the ABS system.
Cars sold in U.S.: The speedometer dis-
plays the speed of the car in miles per hour
(mph).
Cars sold in Canada: The speedometer dis-
plays the speed of the car in kilometres per
hour (km/h).
Fuel gauge Fuel-tank capacity, 18.5 US gal. (70 liters).
The fuel gauge shows the amount of fuel left
in the tank. When this is down to about
2.5 gal. (10 liters), a warning light on the
main instrument panel will come on (see
page 61).
Use the Saab Information display (SID) to
check the approximate distance that can be
traveled on the remaining fuel
(see page 68).
Temperature gauge The temperature gauge shows the temper-
ature of the coolant. The needle should be
in the middle of the scale when the engine
is at normal operating temperature.
If the needle approaches the red zone,
which can occur in very hot weather or when
the engine is under a heavy load, drive in the
highest gear possible, keep the engine revs
low and avoid shifting down.

77 Instruments and controls
Wipers and washers There are three intermittent wiper positions.
Moving the control stalk to the
spring-loaded position between 0 and 2 will
produce a single sweep of the wipers.
The wipers are designed for optimal clean-
ing at all driving speeds. At higher speeds,
it may be possible to detect a slight ”sweep-
ing” sound. This may be due to the
increased air pressure on the blades at
higher speeds.Headlight washers3
33 3If low beam is on, the headlights are washed
every fifth time the windshield washers are
used or if 2 minutes have elapsed since the
windshield was last washed. The headlight
washers cannot be activated separately.
The headlight washers are of the high-pres-
sure type, which means that other parts of
the car may become wet if you activate the
washers while the car is stationary.
Rain sensing wipers3
33 3
The rain sensor automatically controls the
windshield wipers. The sensor is located on
the windshield beside the rearview mirror.
The system varies between single sweeps
of the windshield and continuous wiping
depending on how much water or snow
there is on the windshield.
Activate the system by lifting the control
stalk to position 1. The wipers make one
sweep for reference to see how much water
and snow is on the windshield. In future, the
sensor compares the amount of water and
snow on the windshield with this reference
value.
WARNING
Turn the rain sensor off if the ignition is
ON when clearing snow and ice from the
windshield, to avoid personal injury.NOTETo avoid damaging the windshield wip-
ers, turn the rain sensor off before wash-
ing the car in an automatic carwash.

78 Instruments and controlsWhen the engine has been switched off,
the control stalk must be moved to posi-
tion 0 and back to position 1 to reactivate
the sensor.
Set the sensitivity using the control on the
wiper stalk (the same control as used for
wiper delay on cars not fitted with a rain sen-
sor). The sensor has three sensitivity set-
tings. It is most sensitive when in the upper-
most position (1). When a higher degree of
sensitivity is selected, the wipers make one
sweep of the windshield for reference.
The rain sensor has a daylight and a night
time mode. The sensor measures the
amount of available light and automatically
selects the appropriate mode. The sensor is
more sensitive at night. The function of the
rain sensor is impaired by dry snow.
Rear-window wiper
(SportCombi)3
33 3The rear-window wiper and washer are
operated with the same stalk switch as used
for washing and wiping the windshield and
headlights.
This stalk has two additional switches,
ON/OFF and .
The ON position provides intermittent wip-
ing.
The position provides washing and
wiping. After a few sweeps the wiper stops
or reverts to intermittent wiping, if this has
been chosen. About 15 seconds after com-
pletion of the washing/wiping of the rear
window, the wiper makes a single sweep to
wipe away any remaining washer fluid.
A spring-loaded position between the OFF
and ON positions allows for a single sweep
of the rear-window wiper.
Intermittent wiping of the rear window
occurs when reverse gear is engaged if the
windshield wipers are in position 1, 2 or 3,
see page 77.

80 Instruments and controls
The system has five sensors:
Outdoor temperature sensor
Interior temperature sensor
Sun sensor (mounted on top of the fascia)
Two blended-air temperature sensors
(mounted inside the front floor vents)
Note: If anything is placed over the sun sen-
sor, the ACC system will not function prop-
erly.
Panel vents The panel vents swivel in all directions so
that air can be directed as desired. In winter,
for instance, the outer vents can be directed
onto the door windows for enhanced
demisting.
The flow of air through the panel vents can
be controlled individually for each vent by
means of the adjacent control. The climate
control system works best if the panel vents
are open. If you find the air cold or that it is
drafty, start by directing the air away from
the body. If the center vent is aimed up, it will
cool the interior temperature sensor and
you may need to adjust ACC up or down,
depending upon temperature desired.
