Airbag system components Airbag in steering wheel
 Airbag in instrument panel in front of
passenger seat
 Side airbags in front seat backrests
Convertible: The side airbags help
protect the head also.
 Inflatable curtains along length of headlin-
ing (from front to rear roof pillars)
(Sport Sedan only)
 Safety belt pretensioners for front seats
and outer rear seats.
The airbag system supplements the protec-
tion provided by the safety belts to further
enhance the safety of occupants taller than
55 in. (140 cm).
When the system is activated at the moment
of impact, the airbag inflates and then
deflates through holes in the back. The
whole operation takes roughly 0.1 second,
quicker than the blink of an eye.
The steering wheel and passenger airbags
are so-called smart airbags. The driver and
passenger airbag system compensates for
safety belt usage and the force of the crash
at the moment of impact.Note:
The sensor reacts differently depending on
whether or not the front safety belts 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 safety belt pretensioners to be acti-
vated and for the airbags to remain unin-
flated.
If only Stage I is activated at the moment of
impact, Stage II will automatically be acti-
vated later to neutralize the gas generator in
the airbag.
WARNING
To reduce risk of death or serious 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
comfortably.
 Passengers 12 and under or shorter
than 55 inches (140 cm) must always
travel in the rear seat as the car is fitted
with a passenger airbag.
Never fit a child seat in front of the
passenger airbag.

29 Safety
The driver and passenger front airbags are
triggered by violent front-end crashes. They
are not activated by minor front-end
impacts, if the car overturns or by rear- and
side-impacts.There are two impact sensors on the front
bumper, under the lacquered shell. Very
soon after the moment of impact, these
register that the car is involved in a crash.
Using this information and data from the
central sensor in the control module, the
control module determines whether or not to
inflate the airbags. The control module also
controls whether other components of the
airbag system are to be deployed: safety
belt pretensioners, inflatable curtains (Sport
Sedan) and roll over bars (Convertible).
Which airbag system components are
deployed depends on a number of factors,
such as the force of the crash and the angle
of impact.If the airbag system registers forces equiv-
alent to a high-speed crash (airbags inflated
to Stage II), the inflatable curtains will also
be activated (Sport Sedan) see page 34.
If the airbags are deployed, the positive
terminal of the battery will be disconnected,
See page 204.
If a fault arises in the airbag system during
a journey, the airbag warning lamp on the
main instrument panel will come on and the
Saab Information Display (SID) will display:
The car is equipped as standard with
a passenger airbag.Airbag malfunction.

32 Safety
Front passenger seatThe system is the same as that used on the
driver’s side.
The airbag systems are interconnected and
have a common warning light . The pas-
senger airbag module is housed in the
fascia above the glove compartment and is
marked "AIRBAG".
Both airbags will be inflated in the event of a
moderate to severe frontal, or near-frontal
crash, even if the passenger seat is unoccu-
pied.
The car is equipped as standard with
a passenger airbag.
WARNING
Never secure a rear-facing child seat in
the right front seat of a car equipped with
a passenger airbag. Inflation of the airbag
in the event of a crash could seriously
injure or kill a child.
WARNING
 DEATH or SERIOUS
INJURY can occur
 Children 12 and under or
shorter than 55 inches
(140 cm) can be killed by the
airbag
 The BACK SEAT is the SAFEST place
for children
 NEVER put a rear-facing child seat in
the front
 Sit as far back as possible from the
airbag
 ALWAYS use SAFETY BELTS and
CHILD RESTRAINTS
Never allow a child to stand in front of
the seat or to sit on the lap of a front
seat passenger. Serious injury or
death could result if the airbag is
inflated in a crash.
 The glove compartment must be
closed while travelling. An open glove
compartment door could cause leg
injuries in the event of a crash.

Sensors detect a
deceleration and send

33 Safety
Head protectionThe pillar trim and headlining (not Converti-
ble soft top) are designed to absorb energy,
softening possible blows to the head. After
a crash, these items must be changed in the
seat positions that were occupied. Never fit
accessories to the pillar trim or headlining
as these could reduce the effectiveness of
the head protection and inflatable curtain
(Sport Sedan).
Side-impact protection
The side airbags, which help protect the
upper body (head also in Convertible), are
integrated in the outside edges of the front
seat backrests. The side impact protection
of the Sport Sedan also includes inflatable
curtains (see page 34.
The front seats and outer rear seats have
safety belt pretensioners.
There are two sensors on each side of the
car, one at the rear of each door sill and one
in the lower part of each C-pillar. The side-
impact protection is only activated on the
side of impact, while the safety belt preten-
sioners on both sides are deployed.
Convertible: The Convertible has two side
impact protection sensors, one on each side
of the car. These are located at rear of the
sills.  Never place anything on the dash or in
front of the seat as, in addition to being
a hazard to passengers, this could
interfere with the function of the airbag
in the event of a crash. The same
applies to the mounting of accessories
on the dash.
 Keep feet on the floor – never put feet
up on the dash, on the seat or out of
the window.
 Do not carry anything in your lap.
WARNING
 This car is equipped with side airbags
and no extra seat cover should be
fitted. Failure to observe this warning
could result in the side airbags not
inflating as intended and thus not
providing 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 side-impact protection will only be
activated in the event of a side-on
crash and not in the event of a rear-
end crash or the car rolling over. For
the Convertible’s Roll-over protection
see page 68.
 Damage or wear to the seat cover, or
the seat seam, in the area of the side
airbag must immediately be repaired
by an authorized Saab dealer.

43 Security
Locking a car with dead batteryThe steering wheel lock requires sufficient
battery voltage to lock and unlock. If the bat-
tery voltage drops below a certain level
while the remote control is in the ignition
switch, you will not be able to remove the
remote control.
If you must leave the car, proceed as
follows:
1 Lock the car by pressing down the lock
buttons on the doors.
2 Lock the front left door from outside with
the traditional key (see page 42). The
car is now locked but the car alarm will
remain inactive.
Trunk lidOpening
The trunk lid is unlocked and slightly opened
when the button on the remote control
or on the inside of the driver’s door is
pressed once.
The hazard warning lights will flash three
times to confirm.
Closing
The trunk lid is locked when closed.
If the doors are locked when the trunk lid is
closed it is armed and the movement sensor
in the cabin will be armed.

96 Instruments and controls
Rain sensor (option)The rain sensor automatically controls the
windshield wipers. The sensor is located on
the windshield beside the rearview mirror.
The system varies the frequency of wiping
between single sweeps and continuous
wiping, depending on the amount of pre-
cipitation.
Activate the rain sensor by lifting the stalk
switch to the AUTO position. The wipers
make one sweep for reference to see how
much water is on the windshield. In the
future, the sensor compares the amount of
water on the windshield with this reference
value.If the stalk switch is left in the AUTO position
when the engine is switched off, when the
engine is next started it must first be moved
to the 0 or 3 position and then back to AUTO
to reactivate the sensor.
If the system malfunctions, the wipers will
operate at low speed when the stalk switch
is set to the AUTO position.
WARNING
Turn the rain sensor off if the ignition is
ON to avoid personal injury when clearing
snow and ice from the windshield.NOTICETurn the rain sensor off before washing
the car in an automatic carwash, to avoid
damaging the windshield wipers.
