Bosch ME9 engine management
system, V6 engineThe Bosch ME9 engine management
system is a system that combines sequen-
tial multiport fuel injection, electronic distrib-
utorless ignition and turbocharger boost
pressure control into one system and intake
camshaft phasing control.
The ME9 engine control module (ECM)
monitors many different engine parameters
such as:
 Charge air pressure
 Intake air temperature
 Crankshaft position
 Engine coolant temperature
 Throttle position
 The oxygen content of the exhaust gases.
By processing all of this information, the
ME9 system can contro l fuel injector open-
ing duration, ignition timing, intake camshaft
phasing and turbocharger boost pressure to
provide excellent engine performance while
maintaining low emissions and fuel con-
sumption.
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 va lve. The hydrocar-
bon/air mixture passes through the evap
canister purge valve and into the engine
where it is burned. “ Refueling”, see
page 156.
When refueling, make sure you screw the
filler cap on and keep turning until it has
clicked 3 times.
NOTICEThe ME9 engine management system
continuously monitors the operation of
these systems and has on-board diag-
nostic capabilities (OBD II). If the Service
Engine Light also known as CHECK
ENGINE light in the main instrument illu-
minates, the ME9 ECM has detected a
problem. The car will continue to operate,
but performance may be diminished. You
should have your car checked by a work-
shop as soon as possible. We recom-
mend that you contact a Saab dealer.

216 Car careWipers and washersWiper bladesCheck and clean all wiper blades regularly.
If poor wiper performance is experienced,
clean the windshield with washer fluid. This
is particularly important if the car has been
through an automatic car wash, as these
sometimes leave a wax coating on the wind-
shield.
If wiper performance is still unsatisfactory,
fit new blades.
Windshield1 Press in the two catches (1) together.
2 Hold the wiper arm and move the wiper blade out and diagonally up.
Fitting the wiper blade 1 Align the wiper arm’s guide lug in the blade’s corresponding slot.
2 Move the blade in towards the wiper arm until the two catches grip the blade.
Check that the blade is fitted firmly.
Rear window, SportCombi1 Detach the blade from the arm by press-ing on the mounting for the blade from
below.
2 Fit the new blade by pressing the shaft of the blade into the arm's mounting.
The washer jet, which is located next to the
high-mounted brake light, is not adjustable.

Washers
The reservoir capacity is approx. 6 qts.
(5.8 liters).
When the washer fluid level drops below
1 quart (1 liter), the headlight washers (if
equipped) are deactivated. This is in order
to prioritize the windshield. The following
message is displayed on the SID:
Headlight washers are only available on
certain markets.
Fill with a mixture of washer fluid and water
as recommended by the table on
the packaging to reduce the risk of freezing
and to ensure effective cleaning (see also
page 104).
Washer jetsThe washer jets, which are adjustable, can
be cleaned with a pin if necessary.
WARNING
Take care not to spill washer fluid concen-
trate onto hot surfaces. Washer fluid con-
centrate can contain flammable ingredi-
ents such as alcohol.
Washer fluid level low.
Refill.

218 Car careChanging bulbs
Auto checking of lightsThe bulbs that are most important from the
point of view of traffic safety are monitored
by the car’s electrical system. If one of these
bulbs should fail, a message will be dis-
played on the SID.
Example of SID message:
The following bulbs are not checked: park-
ing lights, front fog lights, reversing lights,
license plate lighting, side marker lights and
side direction indicators.
SportCombi
The tail lights and brake lights consist of
LEDs. If approx. 3/4 of the LEDs on one side
are broken then this is indicated in the SID. If a stop light bulb fails
SportSedan:
If a stop light bulb fails, the
adjacent taillight will act as a stop light to
ensure traffic safety. Change the broken
bulb when possible.
All rear light bulbs are of the same type and
rated 21 W, with the exception of the license
plate lighting which is rated 5 W.
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.NOTICESwitch off the ignition before changing a
bulb, to avoid possible short-circuiting.
Left low beam failure.

Car care
Wrong bulb fitted
If a low or main beam bulb of too high a
rating is fitted, a bulb failure message will be
shown on the SID (a too high wattage bulb
can damage the reflector).
If the following message is displayed but the
bulb shines, it is most likely that an incorrect
bulb has been fitted.
Note
When changing bulbs, fit the same type of
bulb (e.g. Long-Life) as that removed.
Headlight aiming , page 274.
Xenon headlights 3Xenon headlights produce roughly two
times 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 hi gh voltage activates
the xenon gas. The lamps soon reach full
intensity.
Cars with xenon headlights have automatic
levelling. The levelling system is comprised
of two sensors, one on the front suspension
and one on the rear suspension, and a con-
trol unit by the engine bay fuse box. Head-
light alignment is adjus ted automatically to
the car’s load to prevent dazzling drivers in
oncoming traffic.
If a fault is detected in the system, the fol-
lowing message will be displayed on the
SID:
Right high beam failure.
WARNING
Xenon headlights are high tension. All
work on xenon headlights, including
changing bulbs, must be carried out by
dealer personnel.
Headlight levelling
malfunction.
We recommend you to contact a Saab
dealer to have a xenon headlight changed
