174 Car careSaab Trionic engine management
systemThe 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.
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 hydrocarbon/
air mixture passes through the evap canis-
ter purge valve and into the engine where it
is burned. "Refueling", see page 128.
When refueling, make sure you screw the
filler cap on and keep turning until it has
clicked 1 time. Otherwise, it is possible for
the Engine malfunction (CHECK ENGINE)
light to illuminate. The following message
will appear on the SID:
NOTICEThe 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
Trionic 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 Saab dealer
as soon as possible.

188 Car careChanging bulbsAutochecking 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 displayed on the SID.
Example of SID message:
The following bulbs are not checked: parking lights, front fog lights,
reversing lights, license plate lighting, side marker lights and side
direction indicators.If a brake light bulb fails
If a brake light bulb fails, the adjacent tail light will act as a brake 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.
Wrong bulb fitted
If a dipped or main beam bulb of too high a rating is fitted, a bulb
failure message will be shown on the SID (a too high wattage bulb
can damage the reflector).
If the following message is displayed but the bulb shines, it is most
likely that an incorrect bulb has been fitted.
Note:
When changing bulbs, fit the same type of bulb (e.g. Long-Life)
as that removed.
Headlight aiming, page 226.
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.

Right high beam failure.

226 Car careHeadlight 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 per-
pendicular 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
be correctly aimed if the low beam lamps
are aimed properly.
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.
