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.

TiresYour new vehicle comes with high-quality
tires made by a leading tire manufacturer. If
you ever have questions about your tire
warranty and where to obtain service, see
your Saab Warranty and Service Record
Booklet for details.
Inflation - Tire PressureThe Tire-Loading Information label shows
the correct inflation pressures for your tires
when they’re cold. “Cold” means your vehi-
cle has been sitting for at least three hours
or driven no more than 1 mile (1.6 km).Notice:
Don’t let anyone tell you that
underinflation or overinflation is all
right. It’s not. If your tires don’t have
enough air (underinflation), you can get
the following:
Too much flexing
Too much heat
Tire overloading
Bad wear
Bad handling
Bad fuel economy
If your tires have too much air (overinfla-
tion), you can get the following:
Unusual wear
Bad handling
Rough ride
Needless damage from road hazardsAdjust the tire pressure to match the current
load and speed of the car (see page 292).
The stated tire pressures apply to cold tires,
i.e. tires that are the same temperature as
the outside air temperature. Tire pressure
increases as the tires become warm (e.g.
during highway driving) by approximately
4 psi (28 kPa). When the temperature of the
tires changes by 50°F (10°C), the tire pres-
sure will change 2 psi (14 kPa).
Never reduce the pressure of a hot tire. If the
tires are hot when you check them, only
increase the pressure, if necessary.
WARNING
Poor maintained and improperly used
tires are dangerous.
Overloading your tires can cause
overheating as a result of too much
friction. You could have an blow-out
and a serious accident. See “” on
page 251.
Underinflated tires pose the same
danger as overloaded tires. The
resulting accident could cause serious
injury. Check all tires frequently to
maintain the recommended pressure.
Tire pressure should be checked
when your tires are cold.
Overinflated tires are more likely to be
cut, punctured or broken by a sudden
impact – such as when you hit a
pothole. Keep tires at the recom-
mended pressure.
Worn, old tires can cause accidents. If
your tread is badly worn, or if your tires
have been damaged, replace them.93_U S _M 07.book Page 241 W ednesday, April 12, 2006 9:30 AM

251 Car care
Loading Your VehicleThis is an example of what your vehicle´s
Tire-Loading Information/Certification label
might look like. It is located on the B-pillar
and shows how much weight your vehicle
may properly carry. The label tells you the
proper size, and recommended inflation
pressures for the tires on your vehicle. It
also gives you important information about
the number of people that can be in your
vehicle and the total weight that you can
carry. This weight is called the Vehicle
Capacity Weight, and includes the weight of
all occupants, cargo and all nonfactory-
installed options.
Tire Terminology and DefinitionsAir Pressure: The amount of air inside the
tire pressing outward on each square inch of
the tire. Air pressure is expressed in pounds
per square inch (psi) or kilopascal (kPa).
Accessory Weight: This means the com-
bined weight of optional accessories, for
example, automatic transmission, power
steering, power brakes, power windows,
power seats, radio and air conditioning.
Aspect Ratio: The relationship of a tire´s
height to its width.
Belt: A rubber coated layer of cords that is
located between the plies and the tread.
Cords may be made from steel or other rein-
forcing materials.
Bias Ply Tire: A pneumatic tire in which the
ply cords that extend to the beads are laid at
alternate angles substantially less than 90
degrees to the centerline of the tread.
Cold Inflation Pressure: The amount of air
pressure in a tire, measured in pounds per
square inch (psi) or kilopascal (kPa), before
a tire has built up heat from driving. See
“Inflation - Tire Pressure” on page 241.
Curb weight: This means the weight of a
motor vehicle with standard and optional
equipment including the maximum capacity
of fuel, oil and coolant, without passengers
and cargo.
This label can only be found on vehicles
sold in the U.S.
Vehicles sold in Canada have the tire
information label in the glove box, see
page 293.

269 Car care
Other than in extremely cold weather, do not
screen the radiator, e.g. with netting, as this
will greatly diminish its cooling capacity.
Applicable to the manual climate control
system - During cold months the air condi-
tioning should be switched on once or
twice a month and run for 5–10 minutes
during highway driving once the engine is
warm.
This action saves the gaskets in the
compressor from being spoiled. The
compressor uses a lubricant that circu-
lates with the coolant.
Note:
The A/C system cannot be switched on
when the outside temperature is below 32°F
(0°C). Turn on the A/C system when the car
is standing in a warm place. Simplest is to
always have the A/C button pressed in. The
A/C system will then cut in automatically
when the outside temperature is high
enough.
Headlight aimingThe vehicle has a visual optical headlight
aiming system equipped with vertical
aiming device. The aim has been preset at
the factory and should normally not need
further adjustments.
If your headlights are damaged in a crash,
the headlight aim may be affected. If you
believe your headlights need to be re-
aimed, we recommend that you take it to
your Saab dealer for service. However, it is
possible for you to re-aim your headlights as
described in the following procedure.To check the aim, the vehicle should be
properly prepared as follows:
The vehicle shall be placed so that the
headlights are 25 ft (7.6 m) from a light
colored wall or other flat surface. The
aiming area should be darkened, this will
improve your ability to see the beam of the
low beam headlight being aimed.
An optical headlamp aimer can also be
used and will than replace the wall.
The vehicle must have all four wheels on
a perfectly level surface which is level all
the way to the wall or other flat surface.
The vehicle should be placed so it is per-
pendicular to the wall or other flat surface.
The vehicle should be unloaded and fuel
tank full, and one person or 160 lbs.
(75 kg) on the drivers seat.
The vehicle should be fully assembled
and all other work stopped while headlight
aiming is being done.
The vehicle should not have any snow,
ice or mud attached to it.
Tires should be inflated to the prescribed
pressure.
Close all doors.
Rock the vehicle to stabilize the suspen-
sion.
Headlight aiming is done with the vehicle
low beam lamps. The high beam lamps will
be correctly aimed if the low beam lamps
are aimed properly.
WARNING
Before checking/adjusting the headlight
aiming, 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.NOTICETo make sure that your headlights are
aimed properly read all instructions
before beginning. Failure to follow these
instructions could cause damage to
headlight parts or a not correctly aimed
headlight.

278 Customer Assistance and InformationVehicle Data Collection and
Event Data RecordersYour vehicle, like other modern motor vehi-
cles, has a number of sophisticated com-
puter systems that monitor and control sev-
eral aspects of the vehicle’s performance.
Your vehicle uses on-board vehicle comput-
ers to monitor emission control components
to optimize fuel economy, to monitor condi-
tions for air bag deployment and, if so
equipped, to provide anti-lock braking and
to help the driver control the vehicle in diffi-
cult driving situations. Some information
may be stored during regular operations to
facilitate repair of detected malfunctions;
other information is stored only in a crash
event by computer systems commonly
called event data recorders (EDR).
In a crash event, computer systems, such
as the Air Bag Sensing and Diagnostic
Module (SDM) in your vehicle may record
information about the condition of the vehi-
cle and how it was operated, such as data
related to engine speed, brake application,
throttle position, vehicle speed, steering
wheel angle, lateral acceleration, safety belt
usage, air bag readiness, air bag perfor-
mance, and the severity of a collision. This
information has been used to improve vehi-
cle crash performance and may be used to
improve crash performance of future vehi-
cles and driving safety. Unlike the data
recorders on many airplanes, these on-
board systems do not record sounds, such
as conversation of vehicle occupants.To read this information, special equipment
is needed and access to the vehicle or the
SDM is required.
Saab will not access information about a
crash event or share it with others other than
with the consent of the vehicle owner or,
if the vehicle is leased, with the consent of
the lessee,
in response to an official request of police
or similar government office,
as part of Saab’s defense of litigation
through the discovery process, or
as required by law.
In addition, once Saab collects or receives
data, Saab may
use the data for Saab research needs,
make it available for research where
appropriate confidentiality is to be main-
tained and need is shown, or
share summary data which is not tied to a
specific vehicle with non-Saab organiza-
tions for research purposes.
Others, such as law enforcement, may have
access to the special equipment that can
read the information if they have access to
the vehicle or SDM.
If your vehicle is equipped with OnStar®,
please check the OnStar® subscription ser-
vice agreement or manual for information
on its operations and data collection.93_U S _M 07.book Page 278 W ednesday, April 12, 2006 9:30 AM

284 Technical dataEngine oilTo meet demands in Saab's extended service intervals all en-
gines are filled with specially designed synthetic factory fill oils.
Long service intervals, fuel economy and environmental issues
are the base for our choice of oil. By using oils approved by
Saab you minimise the tendencies for oil sludge build, by that
protecting the engine from harmful, wear increasing, deposits.
Approved oils:
For all gasoline engines - fully synthetic engine oil - approved
against the GM-LL-A025 specification - with viscosity SAE 0W-
30 or 0W-40. To benefit from Saab´s specified service intervals,
pleasure ensure to select a fully synthetic engine oil approved
against GM-LL-A025.
For optimum performence Saab recommends the use of Saab
Long Life Turbo Oil 0W-30 or Mobil 1 0W-40 European Car For-
mula, but other fully synthetic oils approved against the above
specification and with proper SAE viscosity 0W-30 or 0W-40
may also be used.Servicing/Oil changes:
To be able to use recommended service intervals the need to
use only approved engine oils is vital. Use only engine oils ap-
proved for your engine. Service should be done according to
the recommended service intervals to optimize your engine's
function through out its entire life. Saab Automobile AB will not
take responsibility for any damage that might occur due to ne-
glecting to meet above mentioned requirements.
At your Saab dealers you can find Saab Genuine or Mobil en-
gine oils. Among those there are oils specially designed to meet
your engines specific needs. We recommend that you, with the
help of our skilled service personnel, choose your oil from that
selection.
Other oil companies also offer engine oils approved against GM
specifications. Oils meeting these standards may be marked as
synthetic. However, not all synthetic engine oils will meet your
engines specific requirements. Please ensure only to use fully
synthetic oils approved against your engines specific require-
ments, i.e. GM-LL-A025 with viscosity SAE 0W-30 or SAE 0W-
40.
Recommended oil viscosities.
Viscosity is a measurement of the oil´s thickness at various
temperatures, according to the SAE standard. The thickness in-
fluences e.g. fuel economy and cold starting properties. For op-
timum performance Saab recommends:
For gasoline engines:
SAE 0W-30 or SAE 0W-40 engine oil.
