Engine malfunction
(CHECK ENGINE)
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 fur-
ther 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.).

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 144).
This light will come on if the engine oil pres-
sure 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 194).
This light will come on if the battery is dis-
charging. If it comes on while you are driv-
ing, stop the car as soon as possible and
switch off the engine.
Check the alternator drive belt (see page
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.This light will come on if there is insufficient
brake fluid in the reservoir (see pages 196).
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 60).
NOTICEThe car should be checked immediately
at a workshop to prevent more serious
faults from arising. We recommend that
you contact an authorized Saab dealer.
Warning, oil pressure
(engine oil)
NOTICE
Under no circumstances must the car be
driven when this warning light is on. Low
oil pressure can result in serious engine
damage.
Warning, charging
Brake warning light
WARNING
Never drive the car when this warning
lights is on. Danger of brake failure!
If the level of brake fluid in the reser-
voir is below the MIN mark, the car
should be towed to a workshop. We
recommend that you contact an
authorized Saab workshop.
Have the brake system checked at
once by a workshop. We recommend
that you contact an authorized Saab
dealer.

This light 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.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 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
oncoming traffic. Adjust your speed accord-
ingly as visibility will be reduced.
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.
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.
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.
Xenon headlight fault
indicator3
NOTICE
If the Xenon headlight fault indicator lights
up, have your car checked as soon as
possible a workshop. We recommend
that you contact an authorized Saab
dealer.
If you do not rectify the problem, nighttime
visibility will be poor since the range of the
headlights is reduced.

62 Instruments and controlsThis light shows when the cruise-control
system is active (see page 159).
This light shows when the headlights are on
high beam (see page 73).
This light shows when the rear fog light is on
(see page 74).
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.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 158.
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
when the selector lever is moved to P, R, M
or L, or when the ignition is switched off.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 154).
Have the automatic transmission checked
by an authorized Saab dealer as soon as
possible.

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.

The ESP
® indicator light is located in the
tachometer and will be illuminated when the
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
® system 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 163).The indicator light goes on when the system
is switched off with the ESP
® button.
IMPORTANT: the system is automatically
engaged every time the engine is started
(see page 163).
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.

(ESP
®) on page 163.

main instrument panel The above warning and indicator lights
should come on when the ignition is
switched on prior to starting. They should go
out after about 3 seconds.
The following lights light up until the engine
is started, presuming that no fault exists:
Oil pressure warning light .
Warning, charging .
InstrumentsTachometerThe tachometer indicates the engine speed
in thousands of revolutions per minute. The
needle may be allowed to enter the broken
red zone on the dial only for an instant.
A safety cut-out function (in the fuel system)
prevents the engine speed from exceeding
approximately 6,000 rpm.
Odometer and trip meter The odometer records the distance traveled
in miles on U.S. vehicles and on Canadian
vehicles the distance indicated is in kilome-
tres, and the trip meter in miles and tenths
(kilometres and tenths of kilometres on
Canadian vehicles). Reset button The reset button has two functions, deter-
mined by whether the ignition is ON or OFF.
When the ignition is ON, pressing the
button will reset the trip meter.
When the ignition is OFF, the display
lights up enabling you to read the odome-
ter and trip meter. Pressing the button a
second time will reset the trip meter.

Speedometer(U.S. speedometer shown)
The speedometer receives signals from the
wheel sensors in the ABS system.
Cars sold in U.S.: The speedometer dis-
plays the speed of the car in miles per hour
(mph).
Cars sold in Canada: The speedometer dis-
plays the speed of the car in kilometres per
hour (km/h).
Fuel gauge Fuel-tank capacity, 18.5 US gal. (70 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 61).
Use the Saab Information display (SID) to
check the approximate distance that can be
traveled on the remaining fuel
(see page 68).
Temperature gauge The 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 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 messages When the engine is started, CHECKING will
appear on the display for about 4 seconds
while the SID CHECK functions are being
performed.
When a CHECK message is activated while
driving, a chime sounds and the message
appears in SID. The number of possible
CHECK messages varies depending on the
car’s specifications.
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 whilst 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.
Briefly press the CLR button to acknowl-
edge a message from the display. After
acknowledgement, the message is dis-
played each time the ignition is re-started
until remedied.The following messages may be displayed:
1) This message will be displayed approximately
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 CLR button, then depressing it a
second time for at least eight seconds until
”SERVICE” appears on the display and a chime
sounds. The message can only be deleted when
it is shown on the SID.
