2000 SAAB 9-5 refuelling

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.

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.
Opening the fuel filler flap in an emergency,
see page 126.
Recommended fuel:The engine in your Saab 9-5 is designed to
operate on unleaded gasoline that has an
octane rating of 87 or higher. Octane rating
is determined according to the formula:
where MON is the Motor Octane Number,
and RON is the Research Octane Number.
The average of these two values is the
octane rating of the gasoline as it appears
on the pump at a retail gas station. This
value is sometimes referred to as the
"Anti-Knock Index" (AKI) or the "Average
Octane Number" (AON).To avoid deposit formation on the fuel injec-
tors which can cause poor driveability, use
only quality gasolines that contain deter-
gents and corrosion inhibitors. Because
gasolines sold at retail gas stations vary in
their composition and quality, you should
switch to a different brand if you begin expe-
riencing driveability and/or hard starting
problems shortly after refueling your car. In
recent years, a variety of fuel additives and
alcohols or oxygenates have been blended
with gasoline. These types of gasolines may
be found in all parts of the United States and
Canada, but particularly in geographic
areas and cities that have high carbon mon-
oxide levels. Saab approves the use of such
"reformulated" gasolines in its products,
which help in reducing pollution from all
motor vehicles, provided that the following
blending percentages are met by such
fuels:
 Up to 10% ethanol by volume, with corro-
sion inhibitors.
 Up to 15% MTBE by volume (methyl ter-
tiary butyl ether).
 Up to 5% methanol by volume, with an
equal amount of a suitable co-solvent and
added corrosion inhibitors.
Other, less common, fuel additives used by
some gasoline dealers are also acceptable,
provided that the resultant gasoline is not
more than 2.7% oxygen by weight.
Some Canadian and U.S. gasolines contain
an octane enhancing additive called meth-
lycyclopentadienyl manganese tricarbonyl
WARNING
 Never use fuel for any purpose other
than as engine fuel.
 Fuel is highly flammable and can
cause severe burns. Never use an
open flame in the vicinity of gasoline
and do not smoke when refuelling.
