204 Car careEmission 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.
Saab Trionic engine
management system, 4-cyl
engineThe Saab Trionic engine management
system is a unique Saab development that
combines sequential mult iport 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.
WARNING
Engine exhaust, some of its constituents,
and certain vehicle components contain
or emit chemicals known to the State of
California to cause cancer and birth
defects and reproductive harm. In addi-
tion, certain fluids contained in vehicles
and certain products of component wear
contain or emit chemicals known to the
State of California to cause cancer and
birth defects or other reproductive harm.
NOTICEThe Trionic engine management system
continuously monitors the operation of
these systems and has on-board diag-
nostic capabilities (OBD II). If the Service
Engine Light also known as CHECK
ENGINE light in the main instrument illu-
minates, the Trionic ECM has detected a
problem. The car will continue to operate,
but performance may be diminished. You
should have your car checked by a work-
shop as soon as possible. We recom-
mend that you contact a Saab dealer.

Bosch ME9 engine management
system, V6 engineThe Bosch ME9 engine management
system is a system that combines sequen-
tial multiport fuel injection, electronic distrib-
utorless ignition and turbocharger boost
pressure control into one system and intake
camshaft phasing control.
The ME9 engine control module (ECM)
monitors many different engine parameters
such as:
 Charge air pressure
 Intake air temperature
 Crankshaft position
 Engine coolant temperature
 Throttle position
 The oxygen content of the exhaust gases.
By processing all of this information, the
ME9 system can contro l fuel injector open-
ing duration, ignition timing, intake camshaft
phasing and turbocharger boost pressure to
provide excellent engine performance while
maintaining low emissions and fuel con-
sumption.
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 va lve. The hydrocar-
bon/air mixture passes through the evap
canister purge valve and into the engine
where it is burned. “ Refueling”, see
page 156.
When refueling, make sure you screw the
filler cap on and keep turning until it has
clicked 3 times.
NOTICEThe ME9 engine management system
continuously monitors the operation of
these systems and has on-board diag-
nostic capabilities (OBD II). If the Service
Engine Light also known as CHECK
ENGINE light in the main instrument illu-
minates, the ME9 ECM has detected a
problem. The car will continue to operate,
but performance may be diminished. You
should have your car checked by a work-
shop as soon as possible. We recom-
mend that you contact a Saab dealer.

218 Car careChanging bulbs
Auto checking of lightsThe bulbs that are most important from the
point of view of traffic safety are monitored
by the car’s electrical system. If one of these
bulbs should fail, a message will be dis-
played on the SID.
Example of SID message:
The following bulbs are not checked: park-
ing lights, front fog lights, reversing lights,
license plate lighting, side marker lights and
side direction indicators.
SportCombi
The tail lights and brake lights consist of
LEDs. If approx. 3/4 of the LEDs on one side
are broken then this is indicated in the SID. If a stop light bulb fails
SportSedan:
If a stop light bulb fails, the
adjacent taillight will act as a stop light to
ensure traffic safety. Change the broken
bulb when possible.
All rear light bulbs are of the same type and
rated 21 W, with the exception of the license
plate lighting which is rated 5 W.
WARNING
Before changing a bulb in the engine
bay, switch off the engine to avoid the
danger of fingers and hands being
injured by moving parts.
The radiator fan can cut in even when the
engine is switched off.NOTICESwitch off the ignition before changing a
bulb, to avoid possible short-circuiting.
Left low beam failure.

274 Car carecompressor uses a lubricant that circu-
lates with the coolant.
Note
The A/C system cannot be switched on
when the outside temperature is below 32°F
(0°C). Turn on the A/ C system when the car
is standing in a warm place. Simplest is to
always have the A/C button pressed in. The
A/C system will then cu t in automatically
when the outside temperature is high
enough.
Headlight aimingThe vehicle has a visual optical headlight
aiming system equippe d with vertical
aiming device. The aim has been preset at
the factory and should normally not need
further adjustments.
If your headlights are damaged in a crash,
the headlight aim may be affected. If you
believe your headlights need to be
re-aimed, we recommend that you take it to
your Saab dealer for service. However, it is
possible for you to re-aim your headlights as
described in the following procedure. To check the aim, the vehicle should be
properly prepared as follows:
 The vehicle shall be placed so that the
headlights are 25 ft (7.6 m) from a light
colored wall or other flat surface. The
aiming area should be darkened, this will
improve your ability to see the beam of the
low beam headlight being aimed.
An optical headlamp aimer can also be
used and will than replace the wall.
 The vehicle must have all four wheels on a perfectly level surface which is level all
the way to the wall or other flat surface.
 The vehicle should be placed so it is perpendicular to the wall or other flat
surface.
 The vehicle should be unloaded and fuel tank full, and one person or 160 lbs.
(75 kg) on the drivers seat.
 The vehicle should be fully assembled and all other work stopped while headlight
aiming is being done.
 The vehicle should not have any snow, ice or mud attached to it.
 Tires should be inflated to the prescribed pressure.
 Close all doors.
 Rock the vehicle to stabilize the suspen- sion.
Headlight aiming is done with the vehicle
low beam lamps. The high beam lamps will
WARNING
Before checking/adjusting the headlight
aiming, switch off the engine to avoid
danger of fingers and hands being injured
by moving parts.
The radiator fan can start up even when
the engine is switched off.NOTICETo make sure that your headlights are
aimed properly read all instructions
before beginning. Failure to follow these
instructions could cause damage to
headlight parts or a not correctly aimed
headlight.
