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.

206 Car careChanging bulbs Headlight 1 Unscrew the cover from the back of the light units.
2 Unplug the connector.
3 Unhook the spring clip by pushing it forward and then to the side.
4 Remove the bulb.
5 Insert the new bulb, without touching the glass with your fingers.
Line it up so that the three lugs fit into the corresponding slots in
the reflector and secure it with the spring clip.IMPORTANT! When changing bulbs, use the same type of bulb,
(e.g. Long-life).
Headlight aiming, see page 233.
Parking lights The parking-light bulb is fitted in the same light unit as the headlight
bulb.
1 Remove the bulb holder from the lamp unit.
2 Then take the bulb out of the holder.
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. NOTEDo not fit bulbs with a rating above 60/55W, since the headlight
reflector and the wiring of the car are not designed for a higher
wattage.
Do not touch the glass of the bulbs with your fingers. The oil on
your skin can shorten the life of the bulb.

226 Car careEngine bayClean the engine compartment using an
engine detergent and rinse with hot water.
Cover the headlights. If using a high-pres-
sure washer do not aim the spray nozzle on
the:
Radiator
 Throttle cable
 Throttle housing
 Other engine controls
 The alternator
 Ignition system and other electrical com-
ponents
Avoid spraying the hood liner, as this can
become heavy and hang down and touch
the engine when the hood is closed.
Additional care should be taken if using a
high-pressure washer. Hold the nozzle at
right angles to the area to be cleaned. This
is particularly important when spraying
labels.
Do not use gasoline as a cleaning agent or
solvent when carrying out repairs or mainte-
nance. Saab recommends the use of envi-
ronmentally safe degreasing agents.
WashingThe bodywork must be washed frequently.
When the car is new, the body should be
washed by hand using plain cold water and
a clean, soft brush, or in a brushless car-
wash that uses mild detergent. Automatic
carwashes with brushes should be avoided
when the car is new. Do not use automatic
car washes for the first five or six months,
before the paintwork has hardened prop-
erly. Thereafter, use a high quality car wash
soap added to lukewarm water.
Do not use a pressure washer at close
range on stone chip damage, scratches or
other damage to the paintwork. The paint
can otherwise start to flake.
Remove any bird droppings without delay,
as these can discolor the paintwork and
prove difficult to polish out.
Use a soft cloth moistened with methyl alco-
hol to remove splashes of tar or asphalt. Do
not use strong cleaners, as these can dry
out the paintwork. The underside of the car also needs wash-
ing regularly, and this should be done very
thoroughly at the end of winter. Clean the
underside of the car by hand if the car is usu-
ally washed in an automatic car wash with-
out special facilities for underbody cleaning.
Never wash or leave the car to dry in the
sun, but wipe it dry with a chamois leather
immediately after washing to avoid smears
and streaks.
Clean the window glass inside and out using
a high quality window cleaner. This is partic-
ularly important when the car is new, as
upholstery and trim have a tendency to
sweat a little at first.
Keep the glass well cleaned, as this helps to
prevent misting.NOTEAvoid using any alcohol-based cleaners
on the front and rear light clusters, as
these can cause cracking of the lenses.
