55 Instruments and controls
Speedometer (U.S. speedometer
shown)The speedometer receives signals from the
wheel sensors in the ABS system.
If the NIGHT PANEL mode has been
selected, the scale will be illuminated up to
87 mph (140 km/h). The remainder of the
scale will be illuminated if the speed of the
car exceeds 84 mph (135 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 51).
Use the Saab Information display (SID) to
check the approximate distance that can be
traveled on the remaining fuel
(see page 57).
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.
If the needle enters the red zone, the
warning light will come on and an alarm
chime will sound.

154 Starting and drivingRefueling
Only 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 4-cylinder engines
AO N 93 for 3.0t V6 and 2.3T Aero, (see
page 252).
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 refueling 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
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.
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.
 Do not use the phone when refueling .
Gasoline fuels are highly explosive.
NOTEDo not overfill. Fuel should not come right
up the filler pipe as expansion room is
needed.

155 Starting and driving
Opening the fuel filler flap in an emergency,
see page 145.
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
(MMT). If such fuel is used, your emission
control system performance may deterio-
rate and the malfunction indicator lamp on
your instrument panel may turn on. If this
occurs, return to your authorized Saab
dealer for service.
However, these blended gasolines are reg-
ulated and should never exceed these rec-
ommended blend percentages and service
station operators should know if their gaso-
lines contain detergents and oxygenates,
and have been reformulated to reduce vehi-
cle emissions. Nevertheless, if you begin to
notice a problem with the way your car starts
or runs shortly after it has been refueled, try
a different brand of gasoline.
NOTE Fill to maximum filling capacity
 Stop filling after the first time that the
nozzle trips to shut off the flow of fuel
 Filling capacity can differ between
different fuel stations and outside
temperature. Fuel tank volume when
nozzle trips to shut off, may vary by
0.5 gal. (2 liters).
 Do not fill fuel all the way up the filler
pipe. The gasoline must be allowed
room for expansion especially during
hot weather.
