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.

212 Car careTransmission fluidManual transmission
Check and top up the oil in accordance with
the service program.
Automatic transmission
Check and top up the oil in accordance with
the service program.Coolant
There is an overpressure in the cooling
system. Coolant temperatures can some-
times exceed 212° F (100° C).
If the coolant level drops too low, the follow-
ing message appears on the SID:
The properties of the coolant are retained
for the entire service life of the car. There-
fore, it is not necessary to change the cool-
ant.
The coolant contains 45 % antifreeze and
anti-corrosion fluid. This ratio gives the best
cooling effect. Lower concentrations should
be avoided, in view of the corrosion risk.
Coolants of a different brand could damage
the engine or cooling system. We therefore
recommend strict use of coolants that have
been approved by Saab.Note
If incorrect coolant is used or added, the
life-time properties will be affected. Even if
the coolant is flushed from the system and
replaced with life-time coolant, life-time
properties are no longer retained and the
coolant must then be drained and replaced
at regular intervals.
WARNING
Proceed with caution if the radiator is
boiling when you open the hood.
Never remove the expansion-tank
filler cap when the radiator is boiling.
The cooling system is pressurized –
hot coolant and vapor can escape
when the filler cap is released. These
can cause injury to your eyes and
burns. Loosen the cap carefully, and
let the engine cool before removing
the cap.
Exercise care when adding coolant.
Coolant on hot surfaces constitutes a
fire risk.
Coolant level low.
Refill.
NOTEIf the cooling system needs topping up,
mix the antifreeze with the appropriate
quantity of drinking water or distilled
water before adding it to the system.
If undiluted antifreeze is added, the
engine could still freeze and be damaged.
This is because the antifreeze will not mix
properly with the coolant before the ther-
mostat has opened to allow full circula-
tion.

4-cyl engine: The expansion tank is trans-
parent to facilitate checking the coolant
level.
When the engine is cold, the coolant shall lie
on or just above the KALT/COLD mark on
the expansion tank (boundary between the
upper and lower sections of the tank, see
illustration).
Top up with a mixture of equal parts of
Saab-approved concentrated coolant and
clean water. We recommend that you con-
tact an authorized Saab dealer.
If the expansion tank is empty when coolant
is added, run the engine until warm so that
the thermostat opens. Top up the tank
again, as necessary.V6 engine: The expansion tank is not trans-
parent. The cap must be unscrewed so that
the coolant level can be checked. When the
cap is screwed off there are two level mark-
ings, HOT and COLD.
When the engine is cold, the coolant shall lie
on or just above the COLD mark in the
expansion tank.

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.
