55 Instruments and controls
This light together with will come on if
a potentially serious fault has occurred in
the airbag system. The light will come on for about three
seconds when the ignition switch is turned
to the Start or Drive position. It should go out
after the engine has started.This light indicates a malfunction in the
fuel-injection or ignition system. The car
may still be driven with care and with
somewhat diminished performance (see
page 136).This light comes on when there is less than
about 2.5 gallons (10 liters) of fuel left in the
tank.
This light indicates that there is a message
in the Saab Information Display (SID). A
chime will also sound (see page 64).
Airbag warning light
WARNING
 If the airbag readiness light stays on
after you start your vehicle, it means
the airbag system may not be working
properly. One or more of the following
conditions may occur:
– Non-deployment of the airbags in the
event of a crash.
– Deployment of the airbags without a
crash.
– Deployment of the airbags in crashes
less severe than intended.
 To help avoid injury to yourself or
others, have your vehicle serviced
right away if the airbag readiness light
stays on after you start your vehicle.
Engine malfunction
(CHECK ENGINE)
WARNING
An illuminated ”Engine malfunction
(CHECK ENGINE)” indicator light indica-
tes an engine-related problem. While
your car may be able to be driven with the
”Engine malfunction (CHECK ENGINE)”
indicator light illuminated (Limp-home
mode), you are advised to have your car
serviced at an authorized Saab dealer as
soon as possible.
Continued driving without this problem
being corrected might cause serious
further damage to your car and create
unsafe driving conditions. The driver
should be prepared to take action if such
unsafe conditions arise (e.g.brake
smoothly, engage neutral, stop in a suita-
ble place, switch off the engine, etc.).
NOTICEThe car should be checked immediately
at an authorized Saab dealer to prevent
more serious faults from arising.
Indicator, fuel
NOTICE
If the car runs out of fuel, air can be drawn
in with the fuel, which, in turn, can cause
the catalytic converter to be damaged by
overheating.

135 Starting and driving
Useful tips on cold climate
startingIf the engine has failed to start after several
attempts in very cold weather, press and
hold the accelerator down to the floor and
run the starter for 5–10 seconds. This will
prevent the engine being flooded (exces-
sively rich fuel-air mixture).
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.
Limp-home modeThe engine management system has a
diagnostic feature that continually checks a
number of internal functions. If, for example,
a fault is detected in the throttle valve, the
engine management system will go into
Limp-home mode.This limits idling control,
disables the cruise-control system and
limits the capacity of the A/C compressor.
If the limp-home mode is in operation
(”Engine malfunction (CHECK ENGINE)”
light on, see below) and the outside temper-
ature is close to or below freezing, you may
need to use some throttle on starting (some
pressure on the accelerator).
If the diagnostic system has detected a fault
in the engine-management system, the
”Engine malfunction (CHECK ENGINE)”
light on the main instrument panel will
come on (see page 55), indicating that you
should have the car checked as soon as
possible by an authorized Saab dealer.
NOTICEIf the CHECK ENGINE warning light
starts to flash, ease off the accelerator
slightly. If the light does not cease to flash
within 5 seconds, stop the car in a suita-
ble place as soon as possible and turn off
the engine. The car must be towed to an
authorized Saab dealer.
If the CHECK ENGINE warning light flas-
hes, it indicates that the engine is misfi-
ring which can result in damage to the
catalytic converter.

137 Starting and driving
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 (mixture of
precious metals).
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:
 Have the car serviced regularly in accor-
dance with the service program. The fuel
and ignition systems are particularly
important in this context.
 Always be alert to any misfiring of the
engine (not running on all cylinders) and
any loss of power or performance. At the
first sign of a malfunction, reduce speed
and take the car to an authorized Saab
dealer as soon as possible.
 If the engine fails to start (in very cold
weather or if the battery is flat), the car can
be push started (manual gearbox only) or
started using jumper cables to a donor battery. However, as soon as you have
started the engine, it is important that it
runs on all cylinders. If it is misfiring, allow
it to idle for up to five minutes to give it time
to settle and run smoothly. If, after this
time, the engine still fails to run properly,
turn off the engine and get in touch with
an authorized Saab dealer for advice.
 Never park the car on dry grass or other
combustible material. The catalytic con-
verter gets very hot and could therefore
start a fire.
 Never drive off if the engine is misfiring.
 If you jump start the car when the engine
is already up to normal temperature, the engine must start to run on all cylinders.
Stop jump-starting if the engine fails to
start immediately.
Failure to follow these directions could
result in the catalytic converter and associ-
ated components being damaged, and
could represent a breach of the warranty
conditions.
NOTICEUse only unleaded gasoline. Leaded
gasoline is detrimental to the catalyst and
oxygen sensor and will seriously impair
the function of the catalytic converter.
NOTICEIf the car runs out of fuel, it is possible for
air to get into the fuel system. If this
happens, the catalytic converter may
overheat and be damaged.

184 Car care and technical informationEngine familiesSaab cars imported into the United States
and Canada meet all applicable emission
control standards. The engine family and
appropriate tune-up specifications are iden-
tified on a label affixed to the left front inner
fender.
These engine families meet applicable EPA
Federal Standards, California State Stan-
dards and Canadian Federal Standards and
are equipped with the following systems:
 Sequential multiport fuel injection system
 Three way catalytic converter
 Crankcase emissions control system
 Evaporative emission control system
 On-Board diagnostic (OBD II) system.
Emission control
systemsThe systems for controlling emissions to the
atmosphere require regular checking and
adjustment at the intervals specified in the
service program.
In addition to meeting the exhaust emission
regulations and thereby helping to keep the
environment clean, a correctly tuned engine
will also give maximum fuel economy.
WARNING
Engine exhaust, some of its constituents,
and certain vehicle components contain
or emit chemicals known to the State of
CA to cause cancer and birth defects and
reproductive harm. In addition, certain
fluids contained in vehicles and certain
products of component wear contain or
emit chemicals known to the State of Cali-
fornia to cause cancer and birth defects or
other reproductive harm.
