47 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.
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.
Alarm signals When the car alarm is armed, it will be trig-
gered if any door, or the trunk lid or hood, is
opened.
The alarm will also be triggered if an attempt
is made to bypass or short-circuit the igni-
tion switch, or to disconnect the battery.
If the alarm is triggered, the following alarm
signals will be set off:
 Flashing of hazard warning lights for five
minutes.
 Horn wailing for 30 seconds.
The alarm signals will stop if the alarm is
deactivated (car unlocked) during the alarm
period.

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 208).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.

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.

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
151).
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 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 operator
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.NOTICEIf 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.

58 Instruments and controls
Indicator, cruise control
This light shows when the cruise-control
system is active (see page 167).
Indicator, high beam
This light shows when the headlights are on
high beam (see page 69).
Indicator, rear fog light
This light shows when the rear fog light is on
(see page 70).
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.
Xenon headlight fault
indicator
(certain variants only)
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 dazzling drivers in oncoming traffic.
Adjust your speed accordingly as visibility
will be reduced.
Indicator, open door
If a door has not been closed properly, the

59 Instruments and controls
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 161).
Have the automatic transmission checked
by an authorized Saab dealer as soon as
possible.
Indicator TCS/ESP OFF
The indicator light goes on when the Elec-
tronic Stability Program/Traction Control
System is switched off with the TCS/ESP-
button.
IMPORTANT: the system is automatically
engaged every time the engine is started
(see page 171).
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
TCS/ESP button. If a fault is indicated, have
the system checked by an authorized Saab
dealer.
See also ”Traction Control System (TCS)”,
on page 171 and “Electronic Stability Pro-
gram (ESP) on page 172.
Indicator TCS/ESP
The TCS/ESP indicator light is located in the
tachometer and will be illuminated when
TCS/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 TCS/ESP indicates
reduced traction between the tires and the
road, and that extra care should be taken by
the driver.
In normal driving, the TCS/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 171).
NOTICEIf 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.
