2003 SAAB 9-3 fuel cap

126 Starting and drivingLimp-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
"Engine malfunction (CHECK ENGINE)" in
the instrument panel will come on (see page
55). Have the car checked at a Saab dealer
as soon as possible.
The following message is shown on the SID:
Important considarations 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).
To ensure that the catalytic converter con-
tinues to function properly, and also to avoid
damage to the converter and its associated
components, the following points must be
observed:
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.
Reduced engine power.
Contact Saab dealer.
NOTICEIf "Engine malfunction (CHECK
ENGINE)" warning light starts to flash
(indicating that the engine is misfiring and
the catalytic converter 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 mini-
mum throttle permitted by the current traf-
fic situation. Have the car checked as
soon as possible at a Saab dealer.
NOTICEUse only unleaded gasoline. Leaded
gasoline is detrimental to the catalyst and
oxygen sensor and will seriously impair
the function of the catalytic converter.

128 Starting and drivingRefuelingOnly use fuel from a well-known oil com-
pany.
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 93.
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.
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.

129 Starting and driving
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.Filler cap
The filler cap has a bayonet fitting. Turn the
cap approximately 1/4 of a turn until you
hear one click.
If the fuel filler cap is not on correctly, the fol-
lowing message is displayed on the SID:
Manually opening the fuel filler door, see
page 52.
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 155 for information regarding
gasoline anti-freeze.NOTICEDo not overfill. Fuel should not come right
up the filler pipe as expansion room is
needed when the temperature rises.
Tighten fuel filler cap.
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.

131 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
55.
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

174 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 128.
When refueling, make sure you screw the
filler cap on and keep turning until it has
clicked 1 time. Otherwise, it is possible for
the Engine malfunction (CHECK ENGINE)
light to illuminate. The following message
will appear on the SID:
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.
Tighten fuel filler cap.

Oil grade
:
We recommend the use of Saab or Mobile oils, available from
you Saab dealer, for regular oil changes.
These oils are specially developed from high-quality compo-
nents to meet the demands of extended service intervals (max.
18,000 miles (30,000 km) or 2 years). Saab and Mobil oils are
tested and approved in accordance with the GM standard for
long-life oils. Such gasoline engine oils are given the designa-
tion GM-LL-A 025. The requirements are the same for diesel
oils, though these are given the designation GM-LL-B 025.
To ensure optimum engine performance, with regard to lu-
brication, the ability to dissolve residues and the neutrali-
sation of combustion products in the oil, for a service
interval of 18,000 miles (30,000 km) or a maximum of
2 years, the engine oil used must fulfil GM-LL-A 025 (gaso-
line engines) or GM-LL-B 025 (diesel engines).
Only oil of the above grades may be used.
Oils of the above grades contain the additives required for
the engine to function well. We advise against the use of
further additives.
The gasoline engine oil is unique in that not only does it fulfil the
stringent requirements demanded by API and ACEA standards
but also meets ACEA requirements for fuel-saving properties.
