45 Security
Check to ensure that all the doors, plus
trunk lid/tailgate and hood, are closed pro-
perly.
If the fault persists (LED flashing when
another attempt is 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 contact an
authorized Saab dealer.
To avoid inconvenience caused by the
alarm being triggered inadvertently, make
sure that anyone else using the car is fami-
liar 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 horn is on) it can be
turned off by unlocking the car using the
button.
Activating the car alarm The car alarm cannot be activated if the dri-
ver’s door is open or if the ignition switch is
in ON position.
If one of the other doors or the trunk or hood
is open or opened and not closed again
during the 10-second 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-second period has elapsed.
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.
Contact service.”
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.

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 186).
This light will come on together with if
the battery is discharging. If it comes on
while you are driving, stop the car as soon
as possible and switch off the engine.
Check the alternator drive belt (see
page 194). If the belt has broken, the engine
may overheat (cooling system will not func-
tion properly), the battery will not be char-
ged, the A/C compressor will not run and
power assistance for the steering will be
lost.This light will come on together with if
there is insufficient brake fluid in the reser-
voir (see pages 189).
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 war-
ning”, page 54).

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
seconds when the ignition switch is turned
to the Start or Drive position. It should go out
after the engine has started.This light indicates a malfunction in the
fuel-injection or ignition system. The car
may still be driven with care and with
somewhat diminished performance (see
page 136).This light comes on when there is less than
about 2.5 gallons (10 liters) of fuel left in the
tank.
This light indicates that there is a message
in the Saab Information Display (SID). A
chime will also sound (see page 64).
Airbag warning light
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.
Engine malfunction
(CHECK ENGINE)
WARNING
An illuminated ”Engine malfunction
(CHECK ENGINE)” indicator light indica-
tes an 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 driver
should be prepared to take action if such
unsafe conditions arise (e.g.brake
smoothly, engage neutral, stop in a suita-
ble place, switch off the engine, etc.).
NOTICEThe car should be checked immediately
at an authorized Saab dealer to prevent
more serious faults from arising.
Indicator, fuel
NOTICE
If 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.

56 Instruments and controlsThis light shows when the cruise-control
system is active (see page 151).
This light shows when the headlights are on
high beam (see page 67).
This light shows when the rear fog light is on
(see page 68).
The rear fog light is switched off automat-
ically when the engine is switched off. When
the fog light is next needed, it will have to be
switched on manually again.
The rear fog light consists of one light so it
should not be mistaken for brake lights.This light indicates that there is a fault in the
Xenon headlight system, which consists of
xenon headlights and an automatic levelling
system.
If a fault arises in the Xenon headlight sys-
tem, the headlights will be angled down to
avoid impairing the vision of drivers in onco-
ming traffic. Adjust your speed accordingly
as visibility will be reduced.If a door has not been closed properly, the
pictogram will indicate the door concerned
(or tailgate).
This light will come on in cars with automatic
transmission when the S (SPORT) button
on the selector lever has been pressed
(position N or D) see page 150.
In this mode, the gear changes occur later,
at higher engine revs, giving the engine and
transmission a sportier feel.
To cancel the SPORT mode, press the S
button on the selector lever again. The
mode is also deselected automatically
w h e n t h e s e l e c t o r l e v e r i s m o v e d t o P , R , M

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 146).
Have the automatic transmission checked
by an authorized Saab dealer as soon as
possible.
The indicator light goes on when the Elec-
tronic Stability Program is switched off with
the ESP-button.
IMPORTANT: the system is automatically
engaged every time the engine is started
(see page 155).
The indicator light also goes on when there
is a fault in the system. In this case the light
cannot be turned off by means of the ESP
button. If a fault is indicated, have the
system checked by an authorized Saab
dealer.
See also “Electronic Stability Program
(ESP) on page 155.The ESP indicator light is located in the
tachometer and will be illuminated when
ESP regulation is occurring, i.e. when there
is insufficient traction between the tires and
the road surface to provide the grip required
for the acceleration called for. The driver
can also sense that the engine is not
responding normally to the accelerator.
Operation of the ESP indicates reduced
traction between the tires and the road, and
that extra care should be taken by the driver.
In normal driving, the ESP will help to
improve both ride comfort and safety, but
must not be regarded as a system to enable
the driver to drive at or maintain a higher
rate of speed. The same precautions for
safe cornering and driving on slippery roads
must still be applied (see page 155).
Automatic transmission,
fault indicator
NOTICE
If the control module has actuated the
Limp-home function for the automatic
transmission, the car will remain in 5th
gear when D is selected, making it very
sluggish. To overcome this, select posi-
tion L to prevent unnecessary wear on the
transmission. The transmission then
starts in 2nd gear. When the car is moving
you can select position D.
When the indicator light is on, the car
must not be driven with a trailer attached.
