2008 SAAB 9-3 engine

160 Starting and drivingRefueling1 Switch off the engine.
2 Open the fuel 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.Fuel cap
To remove the fuel cap, turn it slowly to the
left (counterclockwise). The fuel cap has a
spring in it; if you let go of the cap too soon,
it will spring back to the right.
When you put the fuel cap back on, turn it to
the right (clockwise) until you hear three
clicks. Make sure the cap is fully installed.
The diagnostic system can determine if the
fuel cap has been left off or is improperly
installed. See Engine malfunction (CHECK
ENGINE) on page 83.
The most effective way to prevent conden-
sation forming in the tank (and thus avoid
possible running problems) is to keep the
tank full.
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.
NOTEDo not overfill. Fuel should not come right
up the filler pipe as expansion room is
needed when the temperature rises.
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 dif-
ferent fuel stations and outside tem-
perature. 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.

161 Starting and driving
Refer to page 187 for information regarding
gasoline anti-freeze.
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.
Filling a portable fuel container Fuel (Gasoline Engine)
Fuel
Use of the recommended fuel is an impor-
tant part of the proper maintenance of your
vehicle.
For optimum performance Saab recom-
mends:
Gasoline engines – AON 90.
Gasoline Octane
Use regular unleaded gasoline with a
posted octane of 87 or higher. If the octane
is less than 87, you may get a heavy knock-
ing 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 con-
sidered 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.
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.
When refueling, hang the fuel cap inside
the fuel door93_US_M08.book Page 161 Friday, May 11, 2007 11:37 AM

162 Starting and drivingGasoline 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
emission system inspection. See Engine
malfunction (CHECK ENGINE) on page 83.
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.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 NOTEGasolines containing oxygenates, such
as ethers and ethanol, and reformulated
gasolines may be available in your area.
We recommend that you use these gaso-
lines, if they comply with the specifica-
tions described earlier. However, E85
(85% ethanol) and other fuels containing
more than 10% ethanol must not be used
in vehicles that were not designed for
those fuels.93_US_M08.book Page 162 Friday, May 11, 2007 11:37 AM

163 Starting and driving
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.
Engine Break-in PeriodPistons, cylinder bores and bearings need
time to obtain uniform, wear-resistant
surfaces.
If a new engine is driven too hard, this grad-
ual process of bedding-in will not be possi-
ble and the life of the engine will be short-
ened.
During the first 1,200 miles (2,000 km),
do not exceed 5,000 rpm.
In addition, refrain from driving the car at full
throttle, other than for brief instances,
during the first 1,800 miles (3,000 km).
Wearing in new brake padsNew brake pads take time to bed in, about
90 miles (150 km) if the car is driven largely
under stop-and-go conditions or about
300 miles (500 km) of highway driving.
To extend the useful life of the pads, avoid
hard braking as much as possible.

165 Starting and driving
Automatic
transmission3
33 3The automatic transmission has an elec-
tronic control module. The control module
receives information including accelerator
position and road speed. Using this and
other information, it controls the hydraulic
pressure of the transmission to ensure that
gear changing is as smooth as possible.The remote control can only be removed
when the selector lever is in the P position.The engine can only be started when the
selector lever is in the P or N position.
When the car is stationary, the engine must
be idling when you move the selector lever
from one position to another. If not, the
transmission could be damaged.
WARNING
Depress the brake pedal when shifting
the selector lever from P or N.
The car must be at a standstill before
P, R or N is selected. You have to have
your foot on the brake pedal to move
the lever out of P. If the car is still
moving when a drive position is subse-
quently selected, this could cause a
crash or damage the automatic trans-
mission.
Never park the car with the selector
lever in a drive position, even if the
parking brake is on.
If you want to leave the car with the
engine running, move the selector
lever to P or N and apply the parking
brake.
NOTEAfter selecting a drive position, pause
briefly to allow the gear to engage (the car
starts to pull a little) before you acceler-
ate.

166 Starting and drivingPark Brake Shift LockThe transmission has a security function
known as Park Brake Shift Lock. To move
the gear selector lever out of the P or N posi-
tion, the gear selector lever detent (catch)
must be pressed in at the same time as the
brake pedal is held depressed.
The detent button on the selector lever has
to be pressed in before the lever can be
moved between certain positions.
Temporary override of Park Brake Shift
Lock, see page 168.
Adaptive gear change patternsThe adaptive gear change pattern function
adapts gear changing to the prevailing driv-
ing conditions. The transmission control
module senses the engine load, vehicle
speed and temperature of the transmission.
A suitable gear change pattern is then
selected automatically to avoid unneces-
sary gear changes and undesired increases
in transmission temperature.
Certain variants use a special change pat-
tern for the first few minutes after a cold start
so that the catalytic converter reaches its
working temperature more quickly.
Thermal transmission protectionThe transmission has built-in protection
against overheating. If the temperature of
the transmission fluid exceeds 302°F
(150°C), engine torque will be limited to
147 ft.lbs. (200 Nm).
The following message is shown on the SID:
If this message appears, stop the car as
soon as it is safe to do so and allow the
engine to idle until the message has gone
out. The selector lever should be in
position P.Gearbox too hot. Make a
safe stop. Open hood.

167 Starting and driving
Sport mode3
33 3
Sport mode is selected using the
button, while the word SPORT illuminates
on the SID . Changing up occurs later
and changing down occurs earlier at the
same accelerator pedal position.
Sport mode will be deselected if:
The Sport button is depressed again
the engine is switched off.
Lock-upThe transmission’s torque converter has a
lock-up function. This can lock the torque
converter, thus reducing the engine speed
and fuel consumption.Kick-downWhen the accelerator is pressed down fully,
a down change is made to optimize acceler-
ation, e.g. for overtaking.
Following this, the next higher gear will be
selected at the optimum engine speed,
unless you ease off the accelerator before
reaching this.Driving in hilly country with a
heavy loadThe transmission fluid can overheat when
the gearbox is strained, for example, when
driving with a trailer on hilly roads. To avoid
the transmission fluid overheating, always
drive with the selector lever in the D posi-
tion. The adaptive gear change patterns are
then active.
High air temperatures or a faulty oil cooler
can also cause the transmission fluid to
overheat. Overheating reduces the service
life of the fluid.
TowingTowing of cars with automatic transmission,
see page 197.Descending hillsIf the speed of the car increases while
descending a steep hill, despite the acceler-
ator being released, the control module will
change down. If you desire more powerful
engine braking, manually select a lower
gear (see page 170).
WARNING
Remember to use the braking effect of the
engine (1st, 2nd or 3rd gear) when you
are descending long or steep hills to
spare the brakes.
Overheating can cause the brakes to
fade!

168 Starting and drivingLimp-homeIf the transmission malfunctions, the control
module will activate limp-home mode. Driv-
ability will be affected to varying degrees.
Cars with 5-speed transmission3
33 3
In this mode, only 2nd and 5th gears are
available. Select 2nd gear when driving at
low speeds and 5th gear at higher speeds.
2nd gear must be selected manually. Select
5th gear manually or move the selector
lever to D, see page 170.
Cars with 6-speed transmission3
33 3
The car may be totally powerless. If this is
case, have the car transported to a work-
shop to have the problem rectified.
The car may feel weak but can be driven
carefully to a workshop to have the prob-
lem rectified.
Drivability may barely be affected.
Irrespective of the drivability of the car, the
car must be taken to a workshop to have the
problem checked and rectified.Temporary override of Park Brake Shift

1 Apply the parking brake.
2 Lift up the rubber mat in the storage
compartment ahead of the selector
lever.
3 Under the floor of the storage compart-
ment is a yellow plastic lever. Use a thin
tool, such as a screwdriver, to press and
hold the plastic lever while moving the
selector lever from P to N.
4 Remove the tool.
5 Release the parking brake if the car is to
be moved immediately, otherwise it
should remain on.
Check fuse 6 in the engine bay fuse box.
If the fuse is OK the battery may be dead.
Contact a workshop to have the problem
checked and rectified. We recommend that
you contact a Saab dealer.NOTEDo not tow a trailer if limp-home mode is
engaged.
NOTEDue to electrical problems it may not be
possible to move the selector lever out of
the park position, even if the ignition is
ON. If for some reason the selector lever
has to be moved out of the park position
(i.e. to tow the car a short distance) do as
described below.
