204 Car careBosch 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 control 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 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.
When refueling, make sure you screw the
filler cap on and keep turning until it has
clicked 3 times.
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) light in
the main instrument illuminates, 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 workshop as
soon as possible. We recommend that
you contact a Saab dealer.

213 Car care
Battery
Check the charge state and electrolyte level
of the battery regularly.If frequent short journeys are made, the
battery may need extra charging. This can
be done with a battery charger or by taking
the car for a long run.
If the battery is not being charged while the
engine is running, the following message
will appear on the SID:
Check the drive belt (see page 216). If the
belt is damaged, the engine may overheat,
the battery may not be charged and the A/C
compressor may not work.
WARNING
When working on the battery, highly
explosive gas can build up. A spark
could ignite this gas that collects
around the battery.
Therefore, always avoid sparks and
open flames in the vicinity of the
battery.
The battery contains corrosive sulphu-
ric acid. Always wear a face mask or
goggles when working on the battery.
If battery acid gets into the eyes or
splashes onto 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 sub-zero temperatures.
Battery not charging.
Make a safe stop.
Checking the battery electrolyte level.
Level correct if level indicator dark.
Battery should be changed if indicator is
light

217 Car care
Wipers 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 catch (1).
2 Pull the complete wiper blade down-
wards so that it comes away from the
wiper arm. Slide the entire blade out
from the arm.
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.

218 Car careWashersThe reservoir capacity is approx. 6 qts.
(5.8 litres).
When the washer fluid level drops below
1 quart (1 litre), 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 102).
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
concentrate can contain flammable ingre-
dients such as alcohol.
Washer fluid level low.
Refill.

219 Car careChanging bulbs
Autochecking 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
Sport Sedan: 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.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 269.
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.
Right high beam failure.

220 Car care
Xenon headlight, low beam3Xenon 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 high 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
control unit by the engine bay fuse box.
Headlight alignment is adjusted automati-
cally 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:
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
