62 Instruments and controls
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 200).
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. 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.
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.

156 Starting and driving
Important considerations with cata-
lytic convertersThe catalytic converter is an emission-con-
trol device incorporated in the car’s exhaust
system. It consists of a metal canister with a
honeycomb insert, the cells of which have
walls coated in a catalytic layer (mixture of
precious metals).
To ensure that the catalytic converter con-
tinues to function properly, and also to avoid
damage to the converter and its associated
components, the following points must be
observed:
 Have the car serviced regularly in accor-
dance with the service program. The fuel
and ignition systems are particularly
important in this context.
 Always be alert to any misfiring of the
engine (not running on all cylinders) and
any loss of power or performance. At the
first sign of a malfunction, reduce speed
and take the car to an authorized Saab
dealer as soon as possible. If the engine fails to start (in very cold
weather or if the battery is dead), the car
can be push started (manual gearbox
only) or started using jumper cables to a
donor battery. However, as soon as you
have started the engine, it is important
that it runs on all cylinders. If it is misfiring,
allow it to idle for up to five minutes to give
it time to settle and run smoothly. If, after
this time, the engine still fails to run prop-
erly, turn off the engine and get in touch
with an authorized Saab dealer for
advice.
NOTEIf the CHECK ENGINE warning light
starts to flash, ease off the accelerator
slightly. If the light does not cease to flash
within 5 seconds, stop the car in a suita-
ble place as soon as possible and turn off
the engine. The car must be towed to an
authorized Saab dealer.
If the CHECK ENGINE warning light
flashes, it indicates that the engine is
misfiring which can result in damage to
the catalytic converter.
NOTEUse only unleaded gasoline. Leaded gas-
oline is detrimental to the catalyst and
oxygen sensor and will seriously impair
the function of the catalytic converter.

157 Starting and driving
 Never park the car on dry grass or other
combustible material. The catalytic con-
verter gets very hot and could therefore
start a fire.
 Never drive off if the engine is misfiring.
 If you jump start the car when the engine
is already up to normal temperature, the
engine must start to run on all cylinders.
Stop jump-starting if the engine fails to
start immediately.
 Failure to follow these directions could
result in the catalytic converter and asso-
ciated components being damaged, and
could represent a breach of the warranty
conditions.
RefuelingOnly fuel from well-known oil companies
should be used.
All Saab gasoline engines can be driven on
fuel of grade AON 87-93.
For optimum performance we recommend:
AO N 90 for 2.0 Turbo 185 hp.
AO N 93 for 2.0 Turbo 205 hp and
2.3 Turbo Viggen.
If fuel containing a mixture of alcohol is
used, the following restrictions apply:
Methanol: max. 5% by volume.
Ethanol: max. 10% by volume.
MTBE: max. 15% by volume.The fuel filler cap is located in the right rear
quarter panel.
Switch off engine.
Insert the fuel-pump nozzle beyond the
flange on the filler pipe. Do not withdraw the
nozzle while filling is in progress.
Cease refueling the first time the pump
stops.
Fuel-tank capacity: 17.0 US gal. (64 liters)
Screw on the filler cap and keep turning until
it has clicked at least three times.
Manually opening the fuel filler door, see
page 150, Convertible, page 58.
The most effective way to prevent conden-
sation forming in the tank (and thus avoid
possible running problems) is to keep the
tank well filled.
Before the onset of freezing temperatures in
winter, it may be advisable to add gasoline
anti-freeze to the fuel a few times to dispel
any condensation in the system.
NOTEIf the car runs out of fuel, it is possible for
air to get into the fuel system. If this
happens, the catalytic converter may
overheat and be damaged.
WARNING
 Never use fuel for any purpose other
than as engine fuel.
 Gasoline is highly flammable and can
cause severe burns. Never use an
exposed flame in the vicinity of gaso-
line. Never smoke when filling the
vehicle up with gasoline.
 Do not use the phone when refueling
with gasoline. Gasoline fuels are
highly explosive.
NOTEDo not overfill. Fuel should not come right
up the filler pipe as expansion room is
needed.

163 Starting and driving
The detent button on the selector lever has
to be pressed before the selector can be
moved between certain positions.
Three modes for the automatic transmis-
sion can be selected: Normal, Sport and
Winter.
The Normal mode, which provides the best
fuel economy, is the default setting when
the engine is started.
Sport mode alters the angle of the throttle
valve for increased power compared to the
same accelerator position in Normal mode.
This means gear changes are made to opti-
mize the car’s performance. The SPORT
indicator light is shown on the main instru-
ment panel; see page 168). The Winter mode is intended for use when
pulling away and driving on icy roads. In this
mode, the transmission starts in 3rd gear, to
provide better grip, and the WINTER indica-
tor appears on the main instrument panel.
When the ignition is turned to OFF, the auto-
matic transmission will automatically revert
to Normal mode (see page 168).Adaptive gear change pattern is a func-
tion of the Normal and Sport modes. It
allows gear changing to be suited to the pre-
vailing driving conditions. The transmission
control module senses the engine load and
temperature of the transmission and selects
one of the four available gear change pat-
terns. Unnecessary gear changes and
undesired temperature increases in the
transmission are avoided.
The automatic transmission has a special
shift pattern during the first minute after a
cold engine is started so that the catalytic
converter will reach its correct working tem-
perature more rapidly

194 Car careEngineThe engine is a transverse four-cylinder
in-line engine with twin overhead camshafts
and 16 valves.
The engine is equipped with two balance
shafts that reduce engine vibration to a min-
mimum.
The balance shafts are chain-driven and
rotate at twice the speed of the crankshaft.
They produce forces and torques that are
opposed to those generated by the pistons
and connecting rods. The effect occurs
twice in each revolution of the engine, coun-
teracting the vibration from its moving parts,
and at the same time reducing unwanted
engine noise.
The gearbox, located on the right (viewed
from the front), is integrated with the engine.
Engine familiesSaab cars imported into the United States
and Canada meet all applicable emission
control standards. The engine family and
appropriate tune-up specifications are iden-
tified on a label affixed to the left front inner
fender.
These engine families meet applicable EPA
Federal Standards, California State Stan-
dards and Canadian Federal Standards and
are equipped with the following systems:
• Sequential multiport fuel injection system.
 Three way catalytic converter.
 Crankcase emissions control system.
 Evaporative emission system.
Emission control
systemsThe systems for controlling emissions to the
atmosphere require regular checking and
adjustment at the intervals specified in the
service program.
In addition to meeting the exhaust emission
regulations and thereby helping to keep the
environment clean, a correctly tuned engine
will also give maximum fuel economy.
