206 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 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.
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.
NOTEThe 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 Tri-
onic 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 workshop as
soon as possible. We recommend 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 control 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 valve. The hydrocar-
bon/air mixture passes through the evap
canister purge valve and into the engine
where it is burned. “Refueling”, see
page 159.
When refueling, make sure you screw the
filler cap on and keep turning until it has
clicked 3 times.
NOTEThe ME9 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 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 workshop as soon as
possible. We recommend that you con-
tact a Saab dealer.

216 Car careBattery
Check the charge state and electrolyte level
of the battery regularly.
If frequent short journeys are made, the bat-
tery may need extra charging. This can be
done with a battery charger or by taking the
car for a long run.
If the battery is not being charged while the
engine is running, the following message
will appear on the SID:
Check the drive belt (see page 219). If the
belt is damaged, the engine may overheat,
the battery may not be charged and the A/C
compressor may not work.
WARNING
When working on the battery, highly
explosive gas can build up. A spark
could ignite this gas that collects
around the battery.
Therefore, always avoid sparks and
open flames in the vicinity of the bat-
tery.
The battery contains corrosive sulphu-
ric acid. Always wear a face mask or
goggles when working on the battery.
If battery acid gets into the eyes or
splashes onto skin or clothing, wash
the affected area liberally with water.
If acid gets into the eyes or a large
quantity makes contact with the skin,
seek medical help.
Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash your hands after
handling
NOTEA discharged battery can freeze and frac-
ture. Batteries should therefore always be
stored away from sub-zero temperatures.
Battery not charging.
Make a safe stop.
Checking the battery electrolyte level.
Dark or green level indicator means
correct fluid level.
Battery should be changed if indicator is
light

222 Car careWasher jetsThe washer jets, which are adjustable, can
be cleaned with a pin if necessary.
Changing bulbs
Autochecking 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.NOTESwitch off the ignition before changing a
bulb, to avoid possible short-circuiting.
Left low beam failure.

275 Car care
Other than in extremely cold weather, do not
screen the radiator, e.g. with netting, as this
will greatly diminish its cooling capacity.
Applicable to the manual climate control
system - During cold months the air condi-
tioning should be switched on once or
twice a month and run for 5–10 minutes
during highway driving once the engine is
warm.
This action saves the gaskets in the
compressor from being spoiled. The
compressor 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 cut in automatically
when the outside temperature is high
enough.
Headlight aimingThe vehicle has a visual optical headlight
aiming system equipped 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.NOTETo 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.
