2004 SAAB 9-3 fuel cap

144 Starting and drivingImportant
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. 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 charging pressure
 The system is optimized for AON 90.
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. Severe engine damage
will occur if gasoline lower than 87
octane is used. However, engine
performance will fall slightly and heavy
loading and laboring should be
avoided. For optimum performance,
use the recommended 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 work-
ing normally, and is perfectly safe for
the engine.
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.NOTICE If the engine sounds strange there is a
malfunction. Contact a Saab dealer
immediately.
 The use of fuel with too low an octane
rating can cause serious engine
damage.

147 Starting and driving
Refueling
Only use fuel from a well-known oil
company.
All Saab gasoline engines can be driven on
gasoline with an octane rating between
AON 87–93.
The engine management system monitors
the combustion and automatically adapts to
the fuel used.
Always use the correct grade of fuel:
unleaded AON 87–93.For optimum performance Saab recom-
mends:
2.0t engine 175 hp – AON 90.
2.0 Turbo engine 210 hp - AON 90.
Sometimes, gasoline can contain a number
of additives containing oxygen. The most
common of these are alcohol or some type
of ether. The maximum oxygen level is
restricted by national regulations.
If fuel containing a mixture of alcohol is
used, the maximum levels approved by
Saab are: 5 % by volume of methanol; or
10 % by volume of ethanol. The most
common type of ether used is MTBE
(methyl tertiary butyl ether), of which fuel
may contain a maximum of 15 % by volume.
Refueling1 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.
WARNING
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
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
damage.

148 Starting and driving
Filler cap
Open the cap by turning it to the left. When
you feel the spring release in the cap, pull
the cap straight out.
To secure the cap after refueling fit the cap
to the fuel pipe and turn it to the right until
three clicks are heard.
The 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 175 for information regarding
gasoline anti-freeze.The fuel door has a built in fuel cap holder
slot located on the fuel door. Slide the white
ring on the cap into the slot.
NOTICEDo 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
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.

150 Starting and driving
Fuel (Gasoline Engine)Use regular unleaded gasoline rated at 87
octane or higher. Use of gasoline with an
octane rating lower than 87 can result in
severe engine damage. Damage caused by
incorrect fuel being used is not covered
under the terms of the New Car Warranty
and will be the responsibility of the owner. It
is recommended that the gasoline meet
specifications which were developed by the
American Automobile Manufacturers Asso-
ciation (AAMA) and endorsed by the Cana-
dian Motor Vehicle Manufacturers Associa-
tion for better vehicle performance and
engine protection. Gasolines meeting the
AAMA specification could provide improved
driveability and emission control system
performance compared to other gasolines.
Be sure the posted octane is at least 87. If
the octane is less than 87, you may get a
heavy knocking noise when you drive. If it’s
bad enough, it can damage your engine. If
you’re using fuel rated at 87 octane or
higher and you hear heavy knocking, your
engine needs service. But don’t worry if you
hear a little pinging noise when you’re accel-
erating or driving up a hill. That’s normal,
and you don’t have to buy a higher octane
fuel to get rid of pinging. It’s the heavy, con-
stant knock that means you have a problem.
NOTICEHigher concentrations of methanol than
listed above, or the use of methanol-
blended gasoline without suitable co-
solvents and corrosion inhibitors, can
damage your car’s fuel system, leading to
the need for repairs which are not
covered by Saab’s product warranty.
NOTICEThe engine control module (ECM) moni-
toring the engine parameters also stores
fault codes.
Under certain circumstances, this may
cause constant illumination of the Engine
malfunction (CHECK ENGINE) lamp
, thus indicating a fault that must be
checked by your Saab dealer, see page
75.
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 a distinct click.
Avoid driving with the fuel low level indi-
cator illuminated. The symbol illuminates
when less than approximately 2.5 gallons
(10 litres) of fuel remains in the tank.
In Canada, look for the
"Auto Makers’ Choice" label on
the fuel pump

194 Car careSaab Trionic engine management
systemThe Saab Trionic engine management
system is a unique Saab development that
combines sequential multiport fuel injection,
electronic distributorless ignition and turbo-
charger boost pressure control into one sys-
tem.
The Trionic engine control module (ECM)
monitors many different engine parameters
such as:
 Intake manifold pressure.
 Intake air temperature.
 Crankshaft position.
 Engine coolant temperature.
 Throttle position.
 The oxygen content of the exhaust gases.
The ECM receives information regarding
engine knocking from a sophisticated feed-
back function in the ignition discharge unit.
By processing all of this information, the Tri-
onic system can control fuel injector open-
ing duration, ignition timing and turbo-
charger boost pressure to provide excellent
engine performance while maintaining low
emissions and fuel consumption.
ORVR (Onboard Refueling Vapor
Recovery)All hydrocarbons formed when refueling will
be recovered by the car and not released
into the atmosphere. The hydrocarbons are
absorbed in an evaporative emission canis-
ter. When the engine is subsequently
started, the evaporative emission canister is
gradually purged as air is sucked into it
through a shut-off valve. The hydrocarbon/
air mixture passes through the evap canis-
ter purge valve and into the engine where it
is burned. “Refueling”, see page 147.
When refueling, make sure you screw the
filler cap on and keep turning until it has
clicked 3 times.
NOTICEThe Trionic engine management system
continuously monitors the operation of
these systems and has on-board diag-
nostic capabilities (OBD II). If the Engine
malfunction (CHECK ENGINE) light in
the main instrument illuminates, the
Trionic ECM has detected a problem. The
car will continue to operate, but perfor-
mance may be diminished. You should
have your car checked by a Saab dealer
as soon as possible.

240 Car careLoading Your VehicleThis is an example of what your vehicle´s
Tire-Loading Information/Certification label
might look like. It is located on the B-pillar
and shows how much weight your vehicle
may properly carry. The label tells you the
proper size, and recommended inflation
pressures the the tires on your vehicle. It
also gives you important information about
the number of people that can be in your
vehicle and the total weight that you can
carry. This weight is called the Vehicle
Capacity Weight, and includes the weight of
all occupants, cargo and all nonfactory-
installed options.
Tire Terminology and DefinitionsAir Pressure: The amount of air inside the
tire pressing outward on each square inch of
the tire. Air pressure is expressed in pounds
per square inch (psi) or kilopascal (kPa).
Accessory Weight: This means the com-
bined weight of optional accessories, for
example, automatic transmission, power
steering, power brakes, power windows,
power seats, radio and air conditioning.
Aspect Ratio: The relationship of a tire´s
height to its width.
Belt: A rubber coated layer of cords that is
located between the plies and the tread.
Cords may be made from steel or other rein-
forcecing materials.
Bias Ply Tire: A pneumatic tire in which the
ply cords that extend to the beads are laid at
alternate angles substantially less than 90
degrees to the centerline of the tread.
Cold Inflation Pressure: The amount of air
pressure in a tire, measured in pounds per
square inch (psi) or kilopascal (kPa), before
a tire har built up heat from driving. See
“Inflation - Tire Pressure” on page 231.
Curb weight: This means the weight of a
motor vehicle with standard and optional
equipment including the maximum capacity
of fuel, oil and coolant, without passengers
and cargo.DOT Markings: A code molded into the
sidewall of a tire signifying that the tire is in
compliance with the U.S. Department of
Transportation motor vehicle safety stan-
dards. The DOT code includes the Tire
Identification Number (TIN), an alphanu-
meric designator which can also indentify
the tire manufacturer, production plant,
brand and date of production.

gines are filled with specially designed synthetic factory fill oils.
Long service intervals, fuel economy and environmental issues
are the base for our choice of oil. By using oils approved by
Saab you minimise the tendencies for oil sludge build, by that
protecting the engine from harmful, wear increasing, deposits.
Approved oils:
All gasoline engines - Fully Synthetic Engine Oil fulfilling GM-
LL-A-025 requirements.
To ensure being able to take advantage of the Saab specified
service intervals, be sure to select a fully synthetic engine oil
fulfilling GM-LL-A-025 requirements.
Servicing/Oil changes:
To be able to use recommended service intervals the need to
use only approved engine oils is vital. Use only engine oils ap-
proved for your engine. Service should be done according to
the recommended service intervals to optimize your engine's
function through out its entire life. Saab Automobile AB will not
take responsibility for any damage that might occur due to ne-
glecting to meet above mentioned requirements.
At your Saab dealers you can find Saab Genuine or Mobil en-
gine oils. Among those there are oils specially designed to meet
your engines specific needs. We recommend that you, with the
help of our skilled service personnel, choose your oil from that
selection.
Other oil companies also have engine oils approved according
to the table above. Oils meeting these standards may be identi-
fied as synthetic. However, not all synthetic oils will meet your
engines requirements. You should only use oil that meets your
engines specific requirements
