2000 SAAB 9-3 check engine light

36 SecurityActivating the car alarmThe car alarm (anti-theft system) is
activated/deactivated when the car is
locked/unlocked by the remote control or by
the key.
The car alarm cannot be activated if the
driver’s door is open or if the ignition switch
is in position ON.
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 every three seconds after the 10-sec-
onds period has elapsed.
Window glass sensorThe car-alarm (anti-theft system) incorpo-
rates a sensor that monitors the window
glass for the sound of breakage. The sensor
is fitted inside the rear dome light (on Con-
vertibles: in the front interior light).
To avoid false alarms, such as the alarm
being triggered by children or pets left inside
the car, the sensor can be temporarily dis-
abled.
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 the next time the car is
unlocked. The sensor can also be enabled
again by repeating the procedure for dis-
abling 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.
9-3 Convertible: when the car is parked
with the soft top down, the glass sensor will
be automatically disabled.
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.
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 remote control.
Take the car to an authorized Saab dealer to
have the system checked.
The LED on the top of the dash dou-
ble-flashes when the car is immobilized.

battery is not charging. If it comes on while
you are driving, stop the car as soon as pos-
sible and switch off the engine.
Check the alternator drive belt (see page
179). If the belt has broken, the engine may
overheat (cooling system will not function
properly), the belt is slack or broken, battery
charging will be poor and engine cooling
unsatisfactory.
Brake warning light
This light will come on together with if
there is insufficient brake fluid in the reser-
voir, see page 176.
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 warn-
ing).
Parking brake warning
light
The light will show when the parking brake
is on (see page 151.)
If the car driven with the parking brake on,
will also come on and a chime will
sound.
The parking brake is mechanical and oper-
ates on the rear wheels.

Anti-lock brake warning
This light together with and indi-
cates that a fault has occurred in the ABS
system. Conventional braking without the
ABS function will still be available.
For safety reasons, stop the car and check
the level of the brake fluid (see page 176).
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.
This 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.

Indicator, fuel
This light comes on when there is less than
about 2.5 gallons (10 litre) of fuel left in the
tank.
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.
 The airbags in your vehicle may not
inflate in a crash, or they could even
inflate without a crash.
 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.
NOTEIf the car runs out of fuel, air can have
been drawn in with the fuel, which, in turn,
can cause the catalytic converter to be
damaged by overheating.

Central warning light
This light comes 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.
 Engine overheating.
 Alternator not charging properly.
The symbol and the chime will also sound if
the ignition key is turned to the ON position
but the engine is not started within 10 sec-
onds.
Cruise Control
indicator light
The symbol is lit when cruise control is
active.
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.
SPORT Mode Indicator
On cars with automatic transmission the
indicator light comes on when you press the
SPORT button on the gear-lever knob.
In SPORT mode, the transmission remains
longer in the (D, 3, 2, 1) gears before
upshifting.
Quit Sport mode by again depressing the
SPORT button; see also page 147.
WINTER Mode Indicator
On cars with automatic transmission the
indicator light comes on when, in the D posi-
tion, you press the WINTER button on the
center console next to the gear selector.
When the car is in the Winter mode it starts
in 3rd gear, which gives a better grip in
slippery conditions by reducing the ten-
dency to spin the wheels.
Quit Winter mode by again depressing the
WINTER button; see also page 147.
WARNING
An illuminated CHECK ENGINE indicator
light indicates a serious engine-related
problem. While your car may be able to be
driven with the 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 fur-
ther 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.).

This light indicates that there is a message
in the SID. A chime will also sound
(see page 63).
Automatic transmission
fault indicator
On a car with an automatic transmission,
this warning symbol is illuminated if a fault
has been detected in the transmission.
Switch the ignition off and on again to check
if the fault persists.
Even if the fault persists, it is still possible in
most cases to drive the car (see page 144).
Have the automatic transmission checked
by an authorized Saab dealer as soon as
possible.
Rear fog light Indicator
This light shows when the rear fog light is on
(see page 73).
The rear fog light is switched off automati-
cally when the engine is switched off. When
the fog light is next needed, it will have to be
switched on manually again.
High beam Indicator
The symbol is lit when the high beam
is on.
Open door Indicator
If a door has not been closed properly, the
pictogram will indicate the door concerned
(or trunk).
Autochecking of lights,
main instrument panel The above warning and indicator lights
should come on when the ignition is
switched on. They go out after about 3 sec-
onds.
The following lamps light up until the engine
starts, as long as no faults exist:
Central warning light .
Oil pressure warning light .
Charge warning light .
NOTEIf the control module has actuated the
Limp-home function for the automatic
transmission, the car will remain in 4th
gear when D is selected, making it very
sluggish. To overcome this, move the
selector lever to position 2.
When the indicator light is on, the car
must not be driven with a trailer attached.

60 Instruments and controlsTemperature gaugeThe 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 enters the red zone, the
warning light will come on and an alarm
chime will sound. 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.
Check fuse 3 (radiator fan) in the fuse panel
under the hood, see page 191.
If the needle repeatedly enters the red zone,
stop the car as soon as it is safe to do so and
check the coolant level by looking at the
level visible through the plastic tank - do not
remove the cap.
If the coolant level falls below the MIN mark,
the SID will display the message ”FILL
COOLANT FLUID”.
Pressure gaugeThe pressure gauge indicates the pressure
in the induction manifold. Under low load
and while the engine is braking there will be
vacuum in the induction manifold.The
needle of the pressure gauge will then move
within the white zone. At higher engine
speeds and higher loads, the turbo-com-
pressor produces an overpressure in the
induction manifold. The needle will then
enter the orange zone. Normally the needle
should not enter the red zone, since a mon-
itoring system sets limits to the charging
pressure and protects the engine.
NOTEIf the needle, despite the above action,
enters the red zone, stop the car immedi-
ately.
If the needle stays in the red zone, stop
the engine.
WARNING
Never open the coolant expansion tank
cap when the engine is hot. It contains hot
coolant under pressure. Failure to heed
this warning may result in personal injury.

61 Instruments and controls
Under certain barometric conditions the
needle may enter the first part of the red
zone without necessarily indicating that a
fault has arisen.
If the needle repeatedly enters the red zone
and the engine at the same time loses
power, because the monitoring system is
holding the charging pressure down, you
should contact an authorized Saab dealer.
If the speed exceeds 143 mph (230 km/h),
the increase in speed will be limited by the
lowering of the boost pressure. The pres-
sure gauge then moves towards the middle
of the orange zone, indicating reduced
engine output and thus reduces the speed
of the car as well.
Fuel gaugeThe fuel-tank capacity is 17.0 gal. (64 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 56).
Use the Saab Information display (SID) to
check the approximate distance that can be
travelled on the remaining fuel
(see page 62).
Refueling; see page 138.
Gear selector indication
(cars with automatic transmission)An indicator showing which gear is selected
is situated in the main instrument panel.
