61 Instruments and controls
This light will come on if a potentially serious
fault has occurred in the airbag system. The light will come on for about three sec-
onds when the ignition switch is turned to
the Start or Drive position. It should go out
after the engine has started.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 fault in the
Xenon headlight system, which consists of
xenon headlights and an automatic levelling
system.
If a fault arises in the Xenon headlight sys-
tem, the headlights will be angled down to
avoid impairing the vision of drivers in
oncoming traffic. Adjust your speed accord-
ingly as visibility will be reduced.
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.
 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.
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.
Xenon headlight fault
indicator3
NOTICE
If the Xenon headlight fault indicator lights
up, have your car checked as soon as
possible a workshop. We recommend
that you contact an authorized Saab
dealer.
If you do not rectify the problem, nighttime
visibility will be poor since the range of the
headlights is reduced.

143 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 (”Ser-
vice Engine Light also known as CHECK
ENGINE” light on, see below) and the out-
side temperature is close to or below freez-
ing, 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
”Service Engine Light also known as
CHECK ENGINE” light on the main
instrument panel will come on (see page
58), indicating that you should have the car
checked as soon as possible by a work-
shop. We recommend that you contact 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 suit-
able place as soon as possible and turn
off the engine. The car must be towed to
a workshop. We recommend that you
contact an authorized Saab dealer.
If the CHECK ENGINE warning light
flashes, it indicates that the engine is mis-
firing which can result in damage to the
catalytic converter.

145 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 a workshop as soon as
possible. We recommend that you
contact an authorized Saab dealer.  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 a
workshop for advice. We recommend that
you contact an authorized Saab dealer.  Never park the car on dry grass or other
combustible material. The catalytic
converter gets very hot and could there-
fore 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 gas-
oline 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.

190 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 Cal-
ifornia to cause cancer and birth defects
or other reproductive harm.
