33 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 58 and
38).
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 front airbags are inflated in two stages.
Stage 1: process is a less severe, softer
inflation of the airbag. This stage is used in
lower force crashes, or if the seat is posi-
tioned close to the steering wheel or dash-
board.
Stage 2: process is a more forceful and
quicker inflation of the airbag. This stage is
used in more severe crashes and/or when
the seat adjustment is back a significant
distance from the steering wheel or dash-
board.
Note:
The sensor reacts differently depending on
whether or not the front seatbelts on the
driver’s and passenger sides are used. Situ-
ations can therefore arise where only one of
the airbags inflates.
The entire process takes less than
0.1 second – literally, faster than the blink-
ing of an eye.
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 reach the steering wheel and
controls comfortably.
 Children 12 and under or shorter than
55 inches (140 cm) should always
travel in the rear as the vehicle is
equipped with an airbag on the
passenger side.
WARNING
 Even if the car is equipped with
AIRBAG, safety belts must still
always be worn by all occupants.
 Note that because an airbag inflates
and deflates extremely rapidly, it will
not provide protection against a
second impact occurring in the same
incident. Always use your safety belt.
 Always sit with the whole of your back
in contact with the backrest of the seat,
and with your seat as far back as is
practical. Otherwise you will be thrown
back against the backrest when the
airbag inflates which could cause you
injury or death. The airbag needs
room in which to inflate.
 Never attach anything to the steering
wheel or passenger side of the instru-
ment panel, as this could result in
injury if the airbag should inflate. The
same applies to anything you might
have in your mouth, such as a pipe, for
instance.
 Some components of the airbag will
be warm for a short time. In some
circumstances the airbag can cause
minor burns or abrasions to the body
when the airbag inflates/deflates.

34 Safety Never rest your hands or forearms on
the steering-wheel center padding.
 If the AIR BAG warning light remains
on after the car has been started or
comes on while you are driving, have
the car checked immediately by an
authorized Saab dealer. The warning
light could signify that the airbags may
not inflate in a crash, or they could
even inflate without a crash. See
page. 58.

36 SafetyFront passenger seat The airbags are interconnected and have a
common warning light. The passenger
airbag module is housed in the fascia above
the glove compartment and is marked ”SRS
AIRBAG”. (SRS = Supplementary Restraint
System)
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.
Side airbags Side 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
predetermined 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
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 12 and
under can be killed by
the airbag
 The back seat is the
safest place for children
 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.
 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 fascia, on the seat or out of
the window.
 Do not carry anything in your lap.

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
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
airbag.
 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 an authorized Saab
dealer. Otherwise there is a risk that
the side impact sensor and the mois-
ture barrier in the front door could be
damaged.

38 Safety
Crash sensingCrash sensing and diagnostic modules
have been used in many automobiles since
air bags were first produced. The technical
information gained from these modules can
be useful to understanding the circum-
stances that led to the air bag deployment.
In addition, information from many field
events can be used in the aggregate to help
manufactures and others better understand
real world crashes. This, in turn, can lead to
improved automotive safety.
Your vehicle is equipped with two electronic
frontal sensors, which helps the sensing
system distinguish between a moderate
frontal impact and a more severe frontal
impact. Your vehicle is also equipped with a
crash sensing and diagnostic module,
which records information about the frontal
air bag system. The module records infor-
mation about the readiness of the system,
when the system commands air bag infla-
tion and driver´s safety belt usage at deploy-
ment or in a near-deployment crash. The
module also records speed, engine rpm,
brake and throttle data etc.
AIR BAG warning light
AIRBAG servicingThe AIRBAG must be inspected as part of
the normal service program but otherwise
may be regarded as maintenance-free.  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
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.
WARNING
 If the airbag readiness light stays on
after you start your vehicle, it means
the air bag system may not be working
properly. See page. 58. The airbags
in your vehicle may not inflate in a
crash, or they could even inflate with-
out a crash.
 To help avoid injury to yourself or
others, have your vehicle serviced
right away if the air bag readiness light
stays on after you start your vehicle.

48 SecurityCar alarm The car alarm (anti-theft system) is acti-
vated/deactivated when the car is
locked/unlocked by the remote control or by
the key, see page 43.
The antenna for the alarm system is located
in the center console.
All the doors plus trunk lid/tailgate and hood
are monitored by microswitches, and win-
dow-glass sensors will trigger the alarm if
any glass is broken. Your Saab 9-5 is equipped with an Elec-
tronic starting interlock (immobilizer), see
page 49 for details.
The car alarm is armed 10 seconds after the
car has been locked by the remote control.
During this ten-second delay period, the
doors, trunk lid/tailgate and hood may still
be opened without the alarm being trig-
gered.
The LED indicator on the instrument panel
fascia will be on continuously during this
period, at the end of which it will start to flash
(once every other second). If a door or the trunk lid/tailgate or hood has
been left open when the car is locked, the
LED on the fascia will flash (three times per
second) for ten seconds to indicate this.
Check to ensure that all the doors, plus
trunk lid/tailgate and hood, are closed prop-
erly.
If the fault persists (LED flashing when
renewed attempt made to activate the car
alarm by remote control), lock the car using
the key instead. The car alarm will not have
been activated and you should get in touch
with an authorized Saab dealer.
To avoid inconvenience caused by the
alarm being triggered inadvertently, make
sure that anyone else using the car is famil-
iar with how both the car alarm and the lock-
ing system work.
If the alarm is tripped (the direction indica-
tors are flashing and the siren is on) it can
be turned off by unlocking the car using the
button.
WARNING
Leaving children or pets unattended in a
locked car is dangerous. It is also danger-
ous to leave children in a vehicle with the
ignition key. A child or others could be
badly injured or even killed.

49 Security
Activating the car alarm The car alarm cannot be activated if the
driver’s door is open or if the ignition switch
is in ON position.
If, on the other hand, one of the other doors
or the trunk or hood is open or opened and
not closed again during the 10-seconds
delay period, it will be excluded from the
alarm function.
If it is then closed, a new delay period of ten
seconds will start, and the door (or trunk or
hood) will once again be secured by the
alarm system.
As usual, the LED will be on continuously
during the new delay period and will start to
flash once every other second after the
10-seconds period has elapsed.
Window glass sensorThe car-alarm system incorporates a
sensor that monitors the window glass for
the sound of breakage. The sensor is fitted
inside the rear dome light.
To avoid false alarms, such as the alarm
being triggered by noise from passers by
when the windows have been left open, or
when children or pets are left inside the car,
the sensor can be temporarily disabled.
To disable the sensor
To disable the sensor, first turn off the igni-
tion and remove the key from the switch.
Next, press and hold the NIGHT PANEL
button until ”DOOR ALARM ONLY” appears
on the Saab Information Display (SID) and
a chime sounds. The car alarm must now be
activated within three minutes, or the glass
sensor will become active again.
The glass sensor will be enabled again
automatically when the car is next unlocked.
The sensor can also be enabled again by
repeating the procedure for disabling it.
When the sensor has been enabled, ”FULL
THEFT ALARM” will appear on the Saab
Information Display (SID).
If a fault is detected in the glass sensor,
”SERVICE THEFT ALARM” will appear on
the Saab Information Display (SID).
Electronic starting interlock
(immobilizer) When the key is inserted in the ignition, a
signal is sent to the receiver. If the signal is
verified, the engine can be started.
Each time the key is removed from the igni-
tion, the electronic immobilizer is activated.
This means that the car cannot be started
without the correct key inserted in the igni-
tion and the immobilizer thus deactivated.
If a fault is detected (e.g. in the transmitter)
”KEY NOT ACCEPTED” will appear on the
Saab Information Display (SID).
In this case, you can still start the car if you
turn the ignition key to ON and press one of
the buttons on the key (providing that the
receiver gets the right signal from the key).
Take the car to an authorized Saab dealer to
have the system checked.
The LED double-flashes when the car is
immobilized.
