The airbag system supplements the protec-
tion provided by the safety belts to further
enhance the safety of occupants taller than
59 in. (150 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.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
(SportSedan and SportCombi) 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 (SportSedan and SportCombi)
see page 42.
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:
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 com-
fortably.
Passengers 12 and under or shorter
than 59 inches (150 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 pas-
senger airbag.
Airbag malfunction.

33 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.
The car is equipped as standard with
a passenger airbag.Note
Impact sensors react differently depending
on whether or not the front safety belts on
the driver’s and passenger sides are used.
Situations can therefore arise where only
one of the airbags inflates. It is also possible
for only the safety belt pretensioners to be
activated 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.When the airbag system is activated all of
the doors are unlocked while the inte-
rior/exterior lighting and the hazard warning
lights are illuminated at the same time.

36 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 box 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
Children can be killed or
seriously injured by the
airbag
The BACK SEAT is the SAFEST place
for children 12 and under or shorter
than 55 inches (140 cm)
ALWAYS use SAFETY BELTS and
CHILD RESTRAINTS
NEVER put a rear-facing child seat in
the front
Sit as far back as possible from the
airbag
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 box must be closed while
travelling. An open glove box door
could cause leg injuries in the event of
a crash.
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.

37 Safety
Passenger Sensing SystemVehicles with a passenger sensing system
have indicator LEDs on the facia. The indi-
cators will be lit during the system check
when you turn the ignition switch 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 85.
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. 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.

41 Safety
The side-impact protection is only activated
on the side of impact, while the safety belt
pretensioners on both sides are deployed.
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.
Convertible: The Convertible has two side
impact protection sensors, one on each side
of the car. These are located at the rear of
the sills.

above should come on when the ignition
switch is turned to ON. They should go out
after about 4 seconds once the engine has
started or after the fault-free self-diagnosis
of each system or function.
InstrumentsTachometerThe tachometer displays the engine speed
in thousands of revolutions per minute.
A protective function (interruption of the fuel
supply) limits the engine speed within the
red zone.

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
displays the speed of the car in kilometres
per hour (km/h).
It receives information about vehicle speed
from the ABS’s wheel sensors.
