Saab 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 hydrocar-
bon/air mixture passes through the evap
canister purge valve and into the engine
where it is burned. "Refueling", see page
157.
NOTEThe Trionic engine management system
continuously monitors the operation of
these systems and has on-board diag-
nostic capabilities (OBD II). If the 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 Saab
dealer as soon as possible.

MAXI fusesThe MAXI fuses are housed in the fuse box
under the hood. These fuses can be
checked in the same way as the other fuses.
The MAXI fuses are designed to protect the
car’s electrical system from being dam-
aged. Each MAXI fuse protects a number of
electrical circuits and functions and there-
fore has a higher rating (amperage) than the
standard fuses. No spare MAXI fuses are
supplied with the car.
DICE / TWICEDICE = Dashboard Integrated Central Elec-
tronics
TWICE = Theft-Warning Central Electronics
DICE and TWICE are electronic control
modules.
DICE controls, among other things:
 Front lights and interior lighting.
 Instrument illumination.
 Intermittent wiper operation.
 Electric heating of rear window and door
mirrors.
TWICE controls, among other things:
 Central locking.
 Car alarm (Anti-theft system).
 Engine immobilizer.
 Auto checking of lights.
 Electric heating of rear seat.
 Safety belt reminder.
 Electrically adjustable passenger seat.The DICE and TWICE control modules are
linked to a data bus, which is basically an
information carrier that allows information to
be exchanged between all the control mod-
ules and components connected to the bus.
If a fault occurs in any of these components,
diagnostic faults codes are set in the rele-
vant control module, which enhances fault
diagnosis at the Saab dealer.
The scan tool connector for fault diagnosis
is located under the instrument panel on the
drivers side.
NOTEIf a MAXI fuse blows, it means that there
is a major fault in the electrical system.
Have the car checked without delay by an
authorized Saab dealer.

233 Car care
Maintenance  The drive belt for the compressor should
be inspected under the regular service
program.
 Clean dirt and insects away from the con-
denser and radiator to prevent clogging.
When washing the car, use the hose to
spray the radiator and condenser (located
forward of the radiator) from both sides
(both from the front of the car and from
inside the engine bay). Do not use a pres-
sure washer.
Caution: Do not use the hose when the
engine is hot.
Other than in extremely cold weather, do not
cover the radiator, e.g. with screen netting,
as this will greatly diminish its cooling capac-
ity.
Note: The A/C system will only operate
when the outdoor temperature is above the
freezing point (0°C, 32°F). Switch on the
A/C system when the car stands in a warm
place.
Headlight aimingThe vehicle is equipped with vertical and
horizontal aim indicators. The aim has been
preset at the factory and should normally not
need further adjustments. This is true even
though your vertical and horizontal aim indi-
cators may not fall exactly on the "0" (zero)
marks on their scales.
If your headlight is damaged in an accident,
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: Place the vehicle on a level pad or surface
 The vehicle should be unladen and fuel
tank full, and one person or 160 lbs.
(75 kg) on the drivers seat
 The vehicle should not have any snow, ice
or mud attached to it
 Tires should be inflated to the prescribed
pressure
 Rock the vehicle to stabilize the suspen-
sion
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.
