195 Car care and technical information
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 and
 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)Hydrocarbon vapors formed when refueling
will be recovered by the car and not
released into the atmosphere. The hydro-
carbons are absorbed in a evaporative
emission canister. When the engine is sub-
sequently started, the evaporative emission
canister is gradually purged as air is sucked
into it through a shut-off valve. The hydro-
carbon/air mixture passes through the evap
canister purge valve and into the engine
where it is burned.
When refueling, make sure you screw the
filler cap on and keep turning until it has
clicked at least 3 times. Otherwise, it is pos-
sible for the CHECK ENGINE light to illumi-
nate.
Refueling, see page 148.
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)” lamp in the main instru-
ment illuminates, this indicates that 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.

207 Car care and technical information
Changing bulbsCheck that the new bulb is working when finished.
Use only "Long Life" bulbs.
Headlight aiming, see page 250.
Xenon headlight




Xenon headlights produce roughly twice as much light as halogen
bulbs and have a significantly longer service life.
The lamp units consist of a gas discharge lamp containing xenon.
When the lights are switched on a very high voltage activates the
xenon gas. The lamps soon reach full intensity.
Cars with xenon headlights have automatic levelling. The levelling
system comprises two sensors on the front axle, one on the rear axle
and a control unit under the headlight housing. Headlight alignment
is regulated automatically to prevent dazzling oncoming traffic.
Alignment is also adjusted during braking.
WARNING
Before changing a bulb in the engine bay, 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.
Xenon headlights




are high voltage and must therefore be
changed at a workshop. We recommend that you contact an
authorized Saab workshop. Work involving high-voltage
components is potentially lethal.NOTICE Since the headlight lenses are made of plastic, rinse dried-on
dirt with water and allow it time to soften up before cleaning
the lenses. Avoid rubbing the lenses when dry and never use
solvents.
 Use de-icer spray instead of scraping the ice off.
NOTICE Do not fit bulbs with a higher rating than 55 W, since the head-
light reflector and the wiring of the car are not designed for a
higher wattage.
 Switch off the ignition before changing a bulb, to avoid possi-
ble short-circuiting.
 Do not touch the glass of the bulbs with your fingers. The oil
on your skin can shorten the life of the bulb.

220 Car care and technical informationMaxi 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 that monitor and control a variety
of functions:
DICE controls (among other things):
 Front lights and interior lighting
 Instrument illumination
 Intermittent wiper operation
 Electric heating of rear window and door
mirrors
 Cooling fans
TWICE controls (among other things):
 Central locking.
 Car alarm (Anti-theft system)
 Engine immobilizer
 Autochecking of lights.
 Electric heating of rear seat
 Safety belt reminder
 Electrically adjustable passenger seatThe 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 facilitates fault
diagnosis. We recommend that you contact
an authorized Saab dealer.
The scan tool connector for fault diagnosis
is located under the instrument panel on the
drivers side.
NOTICEIf a Maxi fuse blows, it means that there is
a major fault in the electrical system.
Have the car checked without delay by a
workshop. We recommend that you con-
tact an authorized Saab dealer.

250 Car care and technical informationRecovery and/or
recycling of automotive
materialsA typical car consists of metals (65–75 %),
plastics (10–15 %), rubber (5 %) and small
quantities of glass, wood, paper and tex-
tiles. The recycling of metals has been com-
monplace for a long time now.
To facilitate sorting of other materials for
recycling, plastic parts, for instance, have
been marked to identify the precise nature
of the plastic.
The quantity of materials in the car that can
be recycled or recovered depends on the
scrapping facilities in different countries. EU
legislation that comes into force in 2006 will
require a minimum of 85 % of the total
weight of materials to be recycled. How-
ever, every major car salvage yard in each
market will receive details from Saab of how
the highest percentage of materials can be
reclaimed.
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.
 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.
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.
