149 Starting and driving
Refueling
1 Switch off the engine.
2 Open the filler cap, located in the
right-hand rear fender.
3 Insert the fuel pump nozzle beyond the
flange on the filler pipe and let the first
mark (a ring, a pimple or the first
spring-coil) rest on the flange. Do not
withdraw the nozzle while filling is in
progress.
4 Cease refueling the first time the pump
stops, and wait a few seconds after
you´ve finished pumping before you
remove the nozzle.Filler cap
When you put the filler cap back on, turn it
to the right (clockwise) until you hear three
clicks. Make sure you fully install the cap.
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.The fuel door has a built in filler cap holder
slot located on the fuel door. Slide the white
ring on the cap into the slot.
Notice: If you need a new fuel cap, be sure
to get the right type. Your dealer can get one
for you. If you get the wrong type, it may not
fit properly
WARNING
If a fire starts while you are refueling, do
not remove the nozzle. Shut off the flow of
fuel by shutting off the pump or by notify-
ing the station attendant. Leave the area
immediately.
NOTICE 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.
When refueling, hang the filler cap inside
the fuel door

Fuel
Use of the recommended fuel is an impor-
tant part of the proper maintenance of your
vehicle.
For optimum performance Saab recom-
mends:
AO N 93
Gasoline Octane
Use premium unleaded gasoline with a
posted octane of 93 or higher for best per-
formance. You may also use regular
unleaded gasoline rated at 87 octane or
higher, but your vehicle's acceleration may
be slightly reduced.
If the octane is less than 87, you may get a
heavy knocking noise when you drive. If this
occurs, use a gasoline rated at 87 octane or
higher as soon as possible. Otherwise, you
might damage your engine. A little pinging
noise when you accelerate or drive uphill is
considered normal. This does not indicate a
problem exists or that a higher-octane fuel
is necessary. If you are using 87 octane or
higher-octane fuel and hear heavy knock-
ing, your engine needs service.Gasoline Specifications
It is recommended that gasoline meet spec-
ifications which were developed by automo-
bile manufacturers around the world and
contained in the World-Wide Fuel Charter
which is available from the Alliance of Auto-
mobile Manufacturers at www.autoalli-
ance.org/fuel_charter.htm. Gasoline meet-
ing these specifications could provide
improved driveability and emission control
system performance compared to other
gasoline.
California Fuel
If your vehicle is certified to meet California
Emission Standards (see the underhood
emission control label), it is designed to
operate on fuels that meet California speci-
fications. If this fuel is not available in states
adopting California emissions standards,
your vehicle will operate satisfactorily on
fuels meeting federal specifications, but
emission control system performance may
be affected. The malfunction indicator lamp
may turn on and your vehicle may fail a
smog-check test. See Engine malfunction
(CHECK ENGINE) on page 58. If this
occurs, return to your authorized Saab
dealer for diagnosis. If it is determined that
the condition is caused by the type of fuel
used, repairs may not be covered by your
warranty.
WARNING
Never fill a portable fuel container while it
is in your vehicle. Static electricity dis-
charge from the container can ignite the
gasoline vapor. You can be badly burned
and your vehicle damaged if this occurs.
To help avoid injury to you and others:
 Dispense gasoline only into approved
containers.
 Do not fill a container while it is inside
a vehicle, in a vehicle’s trunk, pickup
bed or on any surface other than the
ground.
 Bring the fill nozzle in contact with the
inside of the fill opening before operat-
ing the nozzle. Contact should be
maintained until the filling is complete.
 Do not smoke while pumping gaso-
line.95usM06.book Page 150 Thursday, November 17, 2005 8:59 AM

151 Starting and driving
Additives
To provide cleaner air, all gasolines in the
United States are now required to contain
additives that will help prevent engine and
fuel system deposits from forming, allowing
your emission control system to work prop-
erly. You should not have to add anything to
your fuel. However, some gasolines contain
only the minimum amount of additive
required to meet U.S. Environmental Pro-
tection Agency regulations. Saab recom-
mends that you buy gasolines that are
advertised to help keep fuel injectors and
intake valves clean. If your vehicle experi-
ences problems due to dirty injectors or
valves, try a different brand of gasoline.
Gasolines containing oxygenates, such as
ethers and ethanol, and reformulated gaso-
lines may be available in your area to con-
tribute to clean air. Saab recommends that
you use these gasolines, particularly if they
comply with the specifications described
earlier.Notice: Your vehicle was not designed
for fuel that contains methanol. Do not
use fuel containing methanol. It can cor-
rode metal parts in your fuel system and
also damage the plastic and rubber
parts. That damage would not be cov-
ered under your warranty.
Some gasolines that are not reformulated
for low emissions may contain an
octane-enhancing additive called methylcy-
clopentadienyl manganese tricarbonyl
(MMT); ask the attendant where you buy
gasoline whether the fuel contains MMT.
Saab does not recommend the use of such
gasolines.
Fuels containing MMT can reduce the life of
spark plugs and the performance of the
emission control system may be affected.
The malfunction indicator lamp may turn on.
If this occurs, return to your authorized Saab
dealer for service.Fuels in Foreign Countries
If you plan on driving in another country out-
side the United States or Canada, the
proper fuel may be hard to find. Never use
leaded gasoline or any other fuel not recom-
mended in the previous text on fuel. Costly
repairs caused by use of improper fuel
would not be covered by your warranty.
To check the fuel availability, ask an auto
club, or contact a major oil company that
does business in the country where you will
be driving.95usM06.book Page 151 Thursday, November 17, 2005 8:59 AM

154 Starting and drivingWhen the car is stationary, the engine must
be at idling speed when the selector lever is
moved.
You must have your foot on the brake
pedal to move the lever out of park.
If the accelerator is depressed while the
lever is moved, this will result in abnormal
wear in the transmission.
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, Manual and
Sport.
Normal mode
The Normal mode, which provides the best
fuel economy, is the default setting when
the engine is started.
Manual mode (Sentronic): see page 158.
Sport mode
When the Sport mode is selected, the throt-
tle angle is altered to provide more power at
the same throttle setting. The transmission
also changes up later than in Normal mode
to provide higher performance. In this
mode, the SPORT indicator will appear on
the main instrument panel (see page 160).
Adaptive gear-change pattern
Adaptive gear-change pattern is a transmis-
sion function in the Normal and Sport
modes which matches gear changing to
current driving conditions. The transmission
control module senses the load on the
engine and temperature of the transmis-
sion. A suitable gear change pattern is then
selected automatically to avoid unneces-
sary gear changes and undesired tempera-
ture increases in the transmission.
NOTICEAfter selecting a drive position, pause
briefly to allow the gear to engage (the car
starts to pull a little) before you accel-
erate.

155 Starting and driving
Lock-up function The automatic transmission has a lock-up
function, which can render the torque con-
verter inoperative in 3rd, 4th and 5th gears,
thus reducing the engine speed and fuel
consumption.
When the lock-up function comes into oper-
ation, it may give the impression of an over-
drive being engaged.Kick-downWhen the accelerator is pressed down hard,
a change-down to the next gear will be
effected to provide maximum acceleration,
e.g. for overtaking.
Following this, the next higher gear will be
selected at the optimum engine speed for
acceleration or, if you ease off the acceler-
ator, before reaching this.
Park Brake Shift LockThe transmission has a security function
known as Park Brake Shift Lock. To move
the gear selector out of the P position, the
brake pedal must be depressed at the same
time as the gear selector catch (detent) is
pressed in.
Shift Lock override
Check fuse No. 1 (see page 221). If the
problem was cured by changing the fuse or
battery, you do not have to contact a work-
shop.
If the fuse blows again as soon as the Shift
Lock feature is activated you should contact
a workshop. We recommend that you con-
tact an authorized Saab dealer.If the fuse is OK, check the battery regarding
the voltage.
1 Apply the parking brake
2 Make sure the key is in position ON
3 Use a small tool such as a screwdriver
and push the lever (see picture) down-
wards so that the detent button can be
pressed approx. 10 mm
4 Move the selector out of position P to N
5 Remove the tool
6 Release the parking brake if the car is to
be moved immediately; otherwise keep
it applied.NOTICEDue to electrical problems it may not be
possible to move the selector out of the
park position, even if the ignition is ON. If
for some reason the selector has to be
moved out of the park position (i.e. to tow
the car a short distance) do as described
below.

169 Starting and driving
Long-term parkingIf the car is not going to be used for some
time, e.g. 3–4 months, the following steps
are recommended:
 Run the engine to normal temperature
before long-term parking.
 Drain the washer-fluid reservoir and
hoses.
 Wash and wax the car. Clean the rubber
seals on the hood, luggage compartment lid and doors, and lubricate them with
glycerol (glycerin).
 After washing the car, dry the brake discs
by taking the car out on the road and
applying the brakes a few times.
 Fill the fuel tank with fuel to prevent con-
densation forming in it.
 Top up the coolant and check the anti-
freeze before the onset of winter.
 Park the car in a dry, covered and
well-ventilated building. Leave the park-
ing brake OFF!  Disconnect the negative (–) battery lead.
If frost is likely to occur during the
long-term parking, remove the battery
and store it away from the frost.
 Ideally, the car should be put up on blocks,
with the wheels off the ground. If this is not
possible, inflate the tires to about 43 psi
(300 kPa).
 Leave all the windows open a crack and
cover the car with a fabric tarpaulin – not
one made of plastic.

172 Starting and drivingEconomical motoringFactors affecting fuel
consumptionFuel consumption is greatly affected by the
general driving conditions, the way in which
the car is driven and at what speeds, the
weather, the state of the road, the condition
of the car, etc. Breaking-inFuel consumption may be somewhat higher
during the break-in period (the first 3,000–
4,000 miles (5,000–7,000 km) than stated.Weather conditionsFuel consumption can be as much as 10 %
lower in summer than in winter. The higher
consumption in cold weather is explained by
the longer time it takes for the engine to
reach normal operating temperature, and
for the transmission and wheel bearings to
warm up. Fuel economy is also affected by
the distance driven: short journeys of
3–5 miles (5–8 km) do not give the engine
enough time to reach normal temperature.
Strong winds can also affect fuel con-
sumption. How to read the graph above:
If fuel consumption with the engine at
normal temperature is 28 mpg
(10l/100 km), the actual fuel consumption 3
miles (5 km) after the engine has started
from cold will be:
– 23.5 mpg (12l/100 km) at outside temp. of
68°F (20°C) (increase of 20 %).
– 17.7 mpg (16l/100 km) at outside temp. of
32°F (0°C) (increase of 60 %).
– 14 mpg (20l/100 km)) at outside temp. of
–4°F (–20°C) (increase of 100 %).
As can be seen, both the distance travelled
by the car and the outside temperature have
a major impact on fuel consumption after
the engine has started from cold. Thus, if the
car is mainly used for short journeys of
3–5 miles (5–8 km), the fuel consumption
will be 60–80 % higher than normal.

173 Starting and driving
Driving technique To obtain the best running economy, not
only regarding fuel consumption but gen-
eral wear also, regular service is required.
 High speed, unnecessary acceleration,
heavy braking and much low gear work all
gives rise to higher fuel consumption.
 Frequent gear changing in traffic, starting
in cold weather, the use of studded tires
and roof racks, and towing a trailer all
increase fuel consumption.
 Do not run the engine when the car is sta-
tionary.
If idling, it will take much longer before the
engine becomes hot. Engine wear is
greatest during this warming-up phase.
Therefore drive away as soon as possible
after the engine is started and avoid high
revving. Driving in a low gear results in higher fuel
consumption than in a high gear because
of the higher engine speed for a given
road speed. Always change up to a higher
gear as soon as traffic conditions allow
and use the highest gear as much as pos-
sible.
 Check the air pressure in the tires once a
month. Incorrect pressures increase tire
wear. It is better to have slightly higher
pressure than lower.
 Check fuel consumption regularly.
Increased consumption can indicate that
something is wrong and that the car
needs to be checked by a workshop. We
recommend that you contact an autho-
rized Saab dealer.
Practical trials on the roads have demon-
strated that substantial savings in fuel con-
sumption can be made if the above advice
is heeded.
Road conditionsWet roads increase fuel consumption, as do
unpaved roads and driving in hilly country
(the amount of fuel saved driving downhill is
less than the additional amount required to
climb the hill).
WARNING
Never switch the engine off while driving
as the effect of the brakes and power
steering will be greatly reduced.
