185 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 ope-
ning duration, ignition timing and turbochar-
ger 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 rele-
ased into the atmosphere. The hydrocar-
bons are absorbed in a evaporative emis-
sion canister. When the engine is
subsequently started, the evaporative emis-
sion canister is gradually purged as air is
sucked into it through a shut-off valve. The
hydrocarbon/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 138.
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.

192 Car care and technical informationBattery
The battery is provided with a cover to pro-
tect it from radiated heat. If the battery is
exposed to high temperatures, its life will be
shortened. To remove the cover, release
the two clips along its long sides.
The cover fits the standard battery installed
in the car. If a new battery is to be fitted,
make sure that its dimensions are the same
as the standard one.
The battery is maintenance free and should
be changed if the electrolyte level is too low.
The indicator on the top side of the battery
will be white if the battery needs replacing.
The fluid level and the charge level should
be checked regularly.
If frequent short journeys are made, the bat-
tery may need to be given a booster charge.
This can be done either using a battery
charger or by taking the car for a long run.
A car with a standard equipment specifica-
tion and a fully charged battery can be left
for up to 40 days and still have a sufficient
charge for starting. If extra equipment is fit-
ted, such as a car phone, the charge may
only be sufficient for about 15 days.
WARNING
 Work on the battery may entail an
explosion hazard, since the battery
gives off hydrogen which forms an
explosive mixture with the oxygen in
the air.
For this reason, always avoid sparks
or open flames when working near the
battery.
 The battery contains corrosive sulfuric
acid. Always wear a face mask or
goggles when working on the battery.
 If battery acid gets into the eyes or
splashes the skin or clothing, wash the
affected area liberally with water.
If acid gets into the eyes or a large
quantity makes contact with the skin,
seek medical help.
 Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash your hands after
handling.
NOTICEA discharged battery can freeze and frac-
ture. Batteries should therefore always be
stored away from frost.

196 Car care and technical informationUse a small screwdriver to adjust the
washer jet on the rear window wiper of the
9-5 SportWagon, as illustrated.
WashersThe washer-fluid reservoir holds 6.4 quarts
(6 liters). When
"Washer fluid level low.
Refill."
comes up on the SID, the reservoir is down
to about 1 quart (1 liter) of fluid. Add at least
50 % of washer- fluid to water to prevent
freezing and for effective cleaning.
WARNING
Take care not to spill washer fluid
concentrate onto hot surfaces. Washer
fluid concentrate contains flammable
ingredients such as alcohol.

197 Car care and technical information
Changing bulbsCheck that the new bulb is working when finished.Use only "Long Life" bulbs.Headlight aiming, see page 242.
Xenon headlight(if equipped)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 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.

198 Car care and technical informationHeadlight bulb for high beam (Halogen)On cars equipped with Xenon lamps the Halogen lamps are used
only for high beam flasher if the daytime running lights are deacti-
vated and the headlight switch is in the off position (otherwise Xenon
lamp is utilized):
1 Unscrew the cover from the back of the lamp unit. To improve
accessibility to the right-hand headlight, hold aside the induction
air hose. To improve accessibility to the left-hand headlight,
remove the battery cover. Release the two clips along the long
sides of the cover.
