44 SecurityActivating 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 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 SID.
If a fault is detected in the glass sensor,
”SERVICE THEFT ALARM” will appear on
the 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
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.

Indicator and warning
lights A number of indicator and warning lights will
come on when the ignition is switched on
prior to starting. Under normal conditions,
these should go out a few seconds after the
engine has started (see page 56).
Warning, oil pressure
(engine oil)
This light will come on together with if
the engine oil pressure is dangerously low.
If the light flashes or comes on while you are
driving, stop the car, switch off the engine
and check the engine oil level (see page
193). NOTEUnder no circumstances must the car be
driven when the warning light is on. Low
oil pressure can result in serious engine
damage.

the battery is discharging. If it comes on
while you are driving, stop the car as soon
as possible and switch off the engine.

201). If the belt has broken, the engine may
overheat (cooling system will not function
properly), the battery will not be charged,
the A/C compressor will not run and power
assistance for the steering will be lost.
Brake warning light
This light will come on together with if
there is insufficient brake fluid in the reser-
voir (see pages 197 / 197).
If the ABS warning light is on at the same
time, the ABS system may be inoperative
because of a fault (see ”Anti-lock brake
warning”, page 52).
Parking brake warning

is on (see page 185).
If the car is driven with the parking brake still
on, will also come on and a chime will
sound.
The parking brake is mechanical and oper-
ates on the rear wheels.
WARNING
Never drive the car when these warning
lights are on. Danger of brake failure!
Have the brake system checked by an
authorized Saab dealer.
WARNING
 Always apply the parking brake when
parking, see page 185.
 Always apply the parking brake before
removing the ignition key.
 Do not apply the parking brake while
the car is moving.

52 Instruments and controls

Anti-lock brake warning
This light will come on if a fault has occurred
in the ABS system.
On certain variants and as well
as can light up to indicate a fault in the
electronic brake force distribution system
(distribution of the brake pressure between
the front and rear wheels).
Conventional braking without the ABS func-
tion will still be available.
For safety reasons, stop the car and check
the level of the brake fluid (see page 197).If the level is normal, depress the brake
pedal firmly two or three times. Now check
the level again. If the level is still normal, you
may drive the car, with considerable cau-
tion, to the nearest authorized Saab dealer
to have the brake system checked.

Airbag warning light
This light together with will come on if
a potentially serious fault has occurred in
the airbag system.
The light will come on for about three sec-
onds when the ignition switch is turned to
the Start or Drive position. It should go out
after the engine has started.
WARNING
 If the ABS is inoperative, there is a
danger of the rear wheels locking up
on hard braking.
 If the level of brake fluid in the reser-
voir is below the MIN mark, the car
should be towed to an authorized
Saab dealer.
WARNING
 If the airbag readiness light stays on
after you start your vehicle, it means
the airbag system may not be working
properly. One or more of the following
conditions may occur:
- Non-deployment of the airbags in the
event of a crash.
- Deployment of the airbags without a
crash.
- Deployment of the airbags in
crashes less severe than intended.
 To help avoid injury to yourself or
others, have your vehicle serviced
right away if the airbag readiness light
stays on after you start your vehicle.

CHECK message indicator
This light indicates that there is a message
in the SID. A chime will also sound
(see page 63).
Central warning light
This light will come 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.
 Electronic brake force distribution (distri-
bution of brake pressure between front
and rear wheels).
 Engine overheating.
 Alternator not charging properly.
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 (see page
149).
Indicator, fuel
This light comes on when there is less than
about 2.5 gallons (10 liters) of fuel left in the
tank.
WARNING
An illuminated ”Engine malfunction
(CHECK ENGINE)” indicator light indi-
cates a serious engine-related problem.
While your car may be able to be driven
with the ”Engine malfunction (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
further 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.).
NOTEThe car should be checked immediately
at an authorized Saab dealer to prevent
more serious faults from arising.NOTEIf the car runs out of fuel, air can be drawn
in with the fuel, which, in turn, can cause
the catalytic converter to be damaged by
overheating.
