2004 SAAB 9-5 fuel consumption

184 Starting and driving4 Close the doors on the left-hand side of
the car gently, to hold the carrier feet in
place.
5 Now go around to the other side of the
car and remove the plastic cover from
the carrier’s adjustable foot. Fold back
the rubber strip and insert the pins on
the foot into the fixing holes. Do the
same with the other carrier and close the
doors gently.
6 Tighten each carrier by turning the knob
clockwise (by hand). Tighten just
enough to bring the foot up against the
edges of the fixing holes.
Remove the carriers when not in use, as
they increase fuel consumption.
The instructions that accompany the carri-
ers also include advice on driving with a roof
load – we strongly recommend that you
read them carefully.
Fitting the roof carriers (accessory)
9-5 Wagon1 Clean the car’s roof rails.
2 Check the markings on the cross mem-
bers to see which is the front and which
is the rear roof carrier.
3 Place the cross members on the roof
rails, on their respective sides of the
center supports. The cross members
must not be placed beyond the front or
rear joint on the rail. Ensure that the dis-
tance between the cross members is at
least 28 inches (700 mm).
If a roof box is to be fitted, the cross
members must be positioned so that the
tailgate can be opened fully without hit-
ting the roof box.
4 Using your thumb, press the bracket so
that it lies snugly against the outside of
the roof rail. Make sure that the roof car-
riers are seated centrally on the rubber
spacers and that these sit correctly on
the roof rail. Pull the spacers down
slightly on the inside of the roof rail.
5 Center the roof carriers so that they pro-
trude equally on both sides.
6 Tighten the roof carriers by hand.
Ensure that the tightening knobs are
upright once the roof carriers have been
tightened.
7 Make sure the roof carriers are securely
in place.

186 Starting and drivingTires
The tire pressure should match the current
load and speed of the car; see page 279 or
the tire pressure label on page 280.
The tire pressures given apply to cold tires,
that is tires that are the same temperature
as the outside air temperature.
The tire pressure increases as the tires
become warm (e.g. during highway driving)
with approximately 0.3 bar (4 psi). When
the temperature of the tires changes by 50°
(10°C), the tire pressure will change 0.1 bar
(2 psi).Never reduce the pressure of a hot tire. If the
tires are hot when you check them, only
increase the pressure, if necessary.
Underinflated tires wear more quickly than
slightly overinflated tires.
If a valve is leaking, simply unscrew it and fit
a new one.
Important! Remember to adjust the tire
pressures if you change the load in the car
or intend to drive at substantially lower or
higher speeds than normal.
WARNING
Check the tire pressure at least once a
month and before long journeys. Under-
inflation can result in:
 Punctures
 Separation of the tire and tread
 Damage to the sidewalls
 Damage to the rims on poor roads
 Poor handling characteristics
 Premature tire wear
 Increased fuel consumption.

202 Car care and technical informationEngine familiesSaab cars imported into the United States
and Canada meet all applicable emission
control standards. The engine family and
appropriate tune-up specifications are iden-
tified on a label affixed to the left front inner
fender.
These engine families meet applicable EPA
Federal Standards, California State Stan-
dards and Canadian Federal Standards and
are equipped with the following systems:
• Sequential multiport fuel injection sys-
tem.
 Three way catalytic converter.
 Crankcase emissions control system.
 Evaporative emission control system.
 On-Board diagnostic (OBD II) system.
Emission 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
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.
WARNING
Engine exhaust, some of its constituents,
and certain vehicle components contain
or emit chemicals known to the State of
CA to cause cancer and birth defects and
reproductive harm. In addition, certain
fluids contained in vehicles and certain
products of component wear contain or
emit chemicals known to the State of Cali-
fornia to cause cancer and birth defects or
other reproductive harm.
NOTICEThe Trionic engine management systems
continuously monitors the operation of
these systems and have 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.
