204 Car careEmission control
systemsThe systems for controlling emissions to the
atmosphere require regular checking and
adjustment at the intervals specified in the
service program.
In addition to meeting the exhaust emission
regulations and thereby helping to keep the
environment clean, a correctly tuned engine
will also give maximum fuel economy.
Saab Trionic engine
management system, 4-cyl
engineThe Saab Trionic engine management
system is a unique Saab development that
combines sequential mult iport 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
 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.
WARNING
Engine exhaust, some of its constituents,
and certain vehicle components contain
or emit chemicals known to the State of
California to cause cancer and birth
defects and reproductive harm. In addi-
tion, certain fluids contained in vehicles
and certain products of component wear
contain or emit chemicals known to the
State of California to cause cancer and
birth defects or other reproductive harm.
NOTICEThe Trionic 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 Trionic 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.

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.

240 Car careTiresYour 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 hazards. Adjust the tire pressure
to match the current
load and speed of the car (see page 291).
The stated tire pressure s apply to cold tires,
i.e. tires that are t he 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 “Loading
Your Vehicle” on page 250.
 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 pot-
hole. Keep tires at the recommended
pressure.
 Worn, old tires can cause accidents. If your tread is badly worn, or if your tires
have been damaged, replace them.93_US_7carcare_MY09.fm Page 240 Tuesday, April 15, 2008 11:26 AM

250 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 nonfac-
tory-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 kilo pascal (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 ki lo pascal (kPa), before
a tire has built up heat from driving. See
“Inflation - Tire Pressure” on page 240.
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 292.

274 Car carecompressor 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 cu t in automatically
when the outside temperature is high
enough.
Headlight aimingThe vehicle has a visual optical headlight
aiming system equippe d 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 perpendicular 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
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.

282 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,
