2007 SAAB 9-5 ignition

193 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 146.
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.

204 Car care and technical informationChanging bulbs
Check that the new bulb is working when fin-
ished.
Use only "Long Life" bulbs.
Headlight aiming, see page 247.
Xenon headlight3Xenon headlights produce roughly twice as
much light as halogen bulbs and have a sig-
nificantly 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 head-
light housing. Headlight alignment is regu-
lated 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 headlights3 are high voltage
and must therefore be changed at a
workshop. We recommend that you
contact an authorized Saab work-
shop. 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 headlight reflec-
tor and the wiring of the car are not
designed for a higher wattage.
Switch off the ignition before chang-
ing a bulb, to avoid possible short-cir-
cuiting.
Do not touch the glass of the bulbs
with your fingers. The oil on your skin
can shorten the life of the bulb.
