2009 SAAB 9-3 octane

153 Starting and driving
Useful tips on starting the engineIf the engine has failed to start after several
attempts in very cold weather, proceed as
follows:
1 Turn the ignition switch to ON (it is
essential that you turn the ignition to
ON before depressing the accelerator).
2 Press the accelerator to the floor and run
the starter motor for 5-10 seconds. This
will prevent the engine being flooded
(fully depressed accelerator cuts off the
fuel supply).
3 Now start the engine in the normal way
- do not touch the accelerator.
If the engine stalls immediately after starting
(e.g. if the clutch was released too quickly),
do not touch the accelerator when restarting
the engine.
Important
considerations for
driving1 Starting and driving
 Do not use full throttle until the engine
is warm, so as to avoid unnecessary
wear. If the needle of the turbo gauge
repeatedly enters the red zone, the
engine may suddenly lose power, due
to the initiation of a monitoring system
that limits the boost pressure. We
recommend that you contact a Saab
dealer as soon as possible.
 Under certain barometric conditions
(high outside temperature and/or high
altitude) the needle may enter the first
part of the red zone without necessarily
indicating that a fault has arisen.
 A protective function (interruption of the
fuel supply) limits the engine speed.2 Stopping the engine
 Do not rev the engine immediately
before switching it off - stop the engine
when it is idling.
3 Regulating the boost pressure
 One of the advantages of boost pres-
sure regulation is that the engine can
also be run safely on gasoline with a
lower octane rating, although not lower
than AON 87. However, engine perfor-
mance will fall slightly and heavy load-
ing and laboring should be avoided. For
optimum performance, use the recom-
mended grade of fuel.
 The maximum boost pressure is regu-
lated according to the tendency of the
engine to knock. Short-lived knocking
is perfectly normal. This can occur
when the engine is running at about
3,000 rpm under a heavy load. The
extent of this knocking will depend on
the grade of fuel in the tank.
 Isolated instances of knocking can
occur with low-octane fuel. This
controlled form of knocking, followed by
a reduction in the boost pressure, is a
sign that the control system is working
normally, and is perfectly safe for the
engine.

154 Starting and drivingThe light comes on in the event of an engine
or gearbox fault (cars with automatic gear-
box), which may cause driveability prob-
lems but that does not affect exhaust emis-
sion. The car can still be driven but perhaps
with limited performance.
Contact a dealer whenever an opportunity
occurs. We recommend that you contact a
Saab dealer.
Limp-homeThe engine management system has a
diagnostic feature that checks a number of
internal functions. If a fault is detected in the
throttle valve, the engine management
system will set the throttle system to the
limp-home mode. This means:
 idling control will be poor (uneven idling
since regulated by ignition and fuel
supply)
 engine performance will be reduced
 the cruise control will not function
 the capacity of the A/C compressor will be
limited.
If the diagnosis function detects a fault in the
engine management system, the light
"Service Engine Light also known as
CHECK ENGINE" indicator light in the
instrument panel will come on (see
page 83). Have the car checked at a work-
shop as soon as possible. We recommend
that you contact a Saab dealer.
Important considerations with
catalytic 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 (precious
metal alloy).
NOTICE If the engine sounds strange there is a
malfunction. We recommend that you
contact a Saab dealer immediately.
 The use of fuel with too low an octane
rating can cause serious engine dam-
age.
Limited performance.
NOTICEIf "Service Engine Light also known
as CHECK ENGINE" indicator light warn-
ing light starts to flash (indicating that the
engine is misfiring and the catalytic con-
verter can be damaged), ease off the
accelerator slightly. The light should go
out or start to shine constantly. If the light
continues to flash despite easing off the
accelerator, you may continue to drive the
car but at the minimum throttle permitted
by the current traffic situation. Have the
car checked as soon as possible. We rec-
ommend that you contact a Saab dealer.NOTICEUse only unleaded gasoline. Leaded gas-
oline is detrimental to the catalyst and
oxygen sensor and will seriously impair
the function of the catalytic converter.

156 Starting and drivingRefueling
WARNING
If you spill fuel and then something ignites
it, you could be badly burned. Fuel can
spray out on you if you open the fuel cap
too quickly. This spray can happen if your
tank is nearly full, and is more likely in hot
weather. Open the fuel cap slowly and
wait for any “hiss” noise to stop. Then
unscrew the cap all the way.
Gasoline fumes are highly explosive.
Therefore:
never smoke while refueling.
never use gasoline for any purpose
other than as engine fuel.
 gasoline is extremely flammable and
can cause severe burns. No open or
exposed flames near gasoline.
do not use a mobile phone at the
same time as refueling.
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 Do not overfill. Fuel should not come
right up the filler pipe as room for
expansion is needed for when the
temperature rises.
 The use of fuel with too low an octane
rating can cause serious engine dam-
age.
 Clean fuel from painted surfaces as
soon as possible.
 Do not use additives with E85-fuel.
NOTICEThe engine control module (ECM) moni-
toring the engine parameters also stores
fault codes.
Under certain circumstances, this may
cause constant illumination of the “Ser-
vice Engine Light also known as CHECK
ENGINE” indicator light , thus indicat-
ing a fault that must be checked by your
Saab dealer, see page 83.
NOTE: always observe the following two
measures:
 Make sure that the fuel filler cap is
screwed on correctly before the
engine is started. Screw on the fuel
filler cap until you hear 3 clicks.
 Avoid driving with the fuel low level
indicator illuminated. The symbol illu-
minates when less than approximately
2.5 gallons (10 liters) of fuel remains
in the tank.

158 Starting and drivingThe most effective way to prevent conden-
sation forming in the tank (and thus avoid
possible running problems) is to keep the
tank full.
Refer to page 185 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.
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 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. Although
not required, use higher octane fuel for opti-
mum performance- 90 octane for the 2.0T
engine and 93 octane for the 2.8 V6.
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.

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 under hood
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 Service
Engine Light also known as 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 NOTICEGasolines 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_MY09.book Page 159 Tuesday, April 15, 2008 10:30 AM
