49 Instruments and controls

Engine malfunction
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
132).
Indicator, fuel
This light comes on when there is less than
about 2.5 gallons (10 liters) of fuel left in the
tank.
Indicator, cruise control
This light shows when the cruise-control
system is active (see page 145).
Indicator, high beam
This light shows when the headlights are on
high beam (see page 61).
Indicator, rear fog light
This light shows when the rear fog light is on
(see page 62).
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 rear light.
Indicator, open door
If a door has not been closed properly, the
pictogram will indicate the door concerned
(or tailgate).
WARNING
An illuminated “Engine malfunction” indi-
cator light indicates a serious
engine-related problem. While your car
may be able to be driven with the “Engine
malfunction” indicator light illuminated
(Limp-home mode), you are advised to
have your car serviced at a qualified facil-
ity 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 operator
should be prepared to take action if such
unsafe conditions arise (e.g., apply the
brakes, disengage transmission, turn off
the ignition etc.).
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.

133 Starting and driving
advantages of the system is that it
enables the engine to be run safely on
lower-grade fuel, although not lower
than AON 87.
 The maximum boost pressure is
adjusted automatically to the knocking
or pinging tendency of the engine.
Occasional, short-lived knocking when
the engine is under a heavy load is per-
fectly normal; the extent will depend on
the grade of fuel in the tank.
 Isolated instances of knocking are
more likely to occur with low-octane
fuel. This controlled form of knocking,
followed by a reduction in the boost
pressure, is a sign that the wastegate is
functioning and is perfectly safe for the
engine.
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).
NOTEIf constant knocking occurs every time a
load is put on the engine, this indicates a
malfunction in the system.
Have the car checked without delay by an
authorized Saab dealer.
WARNING
If the engine is being run with the car on a
rolling road or dynamometer, to ensure
adequate cooling, air must be blown into
the engine compartment and under the
car at a rate equivalent to the ram-air
effect that would be obtained at the corre-
sponding road speed.
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.

134 Starting and drivingTo 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 flat), the car can
be jump started (manual gearbox only) or
started using jump leads to a donor bat-
tery. However, as soon as you have
started the engine, it is important that it
runs on all cylinders. If it is misfiring, allow
i t t o i d l e f o r u p t o f i v e m i n u t e s t o g i v e i t t i m e
to settle and run smoothly. If, after this
time, the engine still fails to run properly,
turn off the engine and get in touch with an
authorized Saab dealer for advice.  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 associ-
ated components being damaged, and
could represent a breach of the warranty
conditions.
V6 engine: When starting the engine from
cold an electrical pump is activated. This
pump pumps air into the exhaust system so
that the catalytic converter will reach its
normal operating temperature more rapidly.
The pump is active for 30-60 seconds.
RefuelingAlways use the correct grade of fuel:
unleaded AON 87-93.
Saab recommends:
 AON 90 for 4-cylinder engines
 AON 93 for V6-engines and 2.3 Aero,
(see page 228).
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.
Open fuel door
Insert the fuel-pump nozzle beyond the
flange on the filler pipe. Do not withdraw the
nozzle while filling is in progress.
Cease refuelling the first time the pump
stops.
Fuel-tank capacity: 18.5 US gal. (70 liters)
Screw on the filler cap and keep turning until
it has clicked at least three times.
The most effective way to prevent conden-
sation forming in the tank (and thus avoid
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.
NOTEDo not overfill. Fuel should not come right
up the filler pipe as expansion room is
needed.

162 Starting and drivingParking brake The parking brake is situated between the
front seats and acts on the rear wheels.
When the parking brake is on, the indicator
light on the main instrument panel will be on.
To release the parking brake, lift the lever
slightly, press the release button and
release the lever by pushing down on it.
Parking Park where the vehicle will not create an
obstruction or a hazard to other road
users.
 Do not park on dry grass or other combus-
tible material. The catalytic converter gets
very hot and could start a fire.
 Apply the parking brake.
 Engage reverse (automatic transmission:
move selector lever to P (Park)), and
remove the ignition key.
 Lock the car.
WARNING
 Always apply the parking brake when
parking.
 Always apply the parking brake before
removing the ignition key.
 Do not use the parking brake when the
car is moving.
WARNING
Do not leave children or pets unattended
in the car. In warm, sunny weather, the
temperature inside the car can reach
160–180°F (70–80°C).

169 Car care and technical information
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 control system.
 On-Board diagnostic (OBD II) 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.Saab Trionic engine management
systemThe Saab Trionic engine management
system is a unique Saab development that
combines sequential multiport fuel injection,
electronic distributorless ignition and turbo-
charger boost pressure control into one sys-
tem.
The Trionic engine control module (ECM)
monitors many different engine parameters
such as:
 Intake manifold pressure.
 Intake air temperature.
 Crankshaft position.
 Engine coolant temperature.
 Throttle position and
 The oxygen content of the exhaust gases.
The ECM receives information regarding
engine knocking from a sophisticated feed-
back function in the ignition discharge unit.
By processing all of this information, the Tri-
onic system can control fuel injector open-ing duration, ignition timing and turbo-
charger boost pressure to provide excellent
engine performance while maintaining low
emissions and fuel consumption.
NOTEThe Trionic engine management systems
continuously monitors the operation of
these systems and have on-board diag-
nostic capabilities (OBD II).
If the “Engine malfunction” lamp in
the main instrument illuminates, this indi-
cates that the Trionic ECM has detected
a problem. The car will continue to oper-
ate, but performance may be diminished.
You should have your car checked by a
Saab dealer as soon as possible.
