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.

CHECK messages When the engine is started, CHECKING will
appear on the display for about four sec-
onds, while the SID checks are being per-
formed.
When a CHECK message is generated
while the car is being driven, a chime will
sound, INFO DISPL will illuminate on the
main instrument panel, and the message
will appear on the SID. The number of mes-
sages that can be displayed by the SID
varies with the specification of the car.
If more than one CHECK message has
been generated, the
+ symbol will appear to
the left of the text on the display. The mes-
sages appear in order of priority.
If a new fault occurs while another message
is being displayed, the message relating to
the new one will appear for 10 seconds,
after which the display will return to the ear-
lier one.
Press CLEAR once to acknowledge a mes-
sage, whereupon it will be cleared from the
display. It will not be displayed again before
the ignition has been switched off and then
on again. The following messages may be displayed:
1 This message will be displayed approxi-
mately 600 miles (1,000 km) before the next
scheduled service is due, or when 365 days
have elapsed since the last service. The
message should be cleared at the time of that
service (see the Saab Warranties & Service
Record Booklet).
This message can also be deleted by first
briefly pressing the CLEAR button, then
depressing it a second time for at least eight
seconds until ”SERVICE” appears on the dis-
play and a chime sounds. The message can
only be deleted when it is shown on the SID.
Night panelTo improve night-driving conditions inside
the car, the Night Panel mode can be
selected. In this mode, the amount of infor-
mation displayed is reduced, and only the
most important instruments and displays
will be illuminated.
When the Night Panel button is pressed,
only the speedometer will be illuminated (up
to the 87-mph or 140-km/h graduation), all
the other instruments illumination being
extinguished and their needles moved to
zero. Both the SID and the ACC displays will
be extinguished and the backlighting for
switches and other controls will be dimmed.
Note: All indicator and warning lights,
together with the display of CHECK mes-
sages, will operate as normal, except ”Out-
door temperature (Frost warning)”, see
page 60. Message See

160 Starting and driving
Overheated transmission fluid If the automatic-transmission fluid should
overheat, the following message will appear
on the SID:
”TRANSMISSION OVERHEATING”. If this
happens, stop the car and wait for the mes-
sage to be extinguished. Continue driving in
a locked gear that produces an engine
speed of about 3,000 rpm.
Overheating of the automatic-transmission
fluid can occur when the car is towing a
heavy load, such as a camping trailer in hilly
country, with the wrong gear selected,
resulting in abnormally frequent gear
changing. Try selecting position L, 3 or 4.
High ambient temperatures can also
increase the temperature of the transmis-
sion fluid or the oil cooler may be faulty.
Contact an authorized Saab dealer (see
also page 173).
Driving on hilly roads with a heavy
loadThe transmission fluid can overheat when
the gearbox is strained, for example, when
driving with a trailer on hilly roads with the
wrong gear is selected, resulting in many
extra gear changes. To avoid the transmis-
sion fluid overheating, always drive in
Normal mode. The adaptive gear change
patterns are then active.
High air temperatures or a faulty oil cooler
can also cause the transmission fluid to
overheat. Overheating reduces the service
life of the fluid. Contact an authorized Saab
dealer (see also page 173). Towing Towing of cars with automatic transmission,
see page 180.
NOTEIf 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, move the
selector lever to position L.
WARNING
Remember to use engine-braking (selec-
tor position L, 3, or 4) to spare the brakes
when you are driving on a long or steep
downhill slope.
Brake failure can result from overheated
brakes!
