169 Car care and technical information
Engine 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 system.
 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.
NOTEThe Trionic engine management systems
continuously monitors the operation of
these systems and have on-board diag-
nostic capabilities (OBD II).
If the “Engine malfunction” lamp in
the main instrument illuminates, this indi-
cates that the Trionic ECM has detected
a problem. The car will continue to oper-
ate, but performance may be diminished.
You should have your car checked by a
Saab dealer as soon as possible.

174 Car care and technical informationCoolant The expansion tank is transparent to facili-
tate checking of the coolant level.
When the engine is cold, the coolant must
not lie over the KALT/COLD mark on the
expansion tank.
If the message “FILL COOLANT FLUID” is
displayed on the SID, check the level of fluid
in the expansion tank.
Top up, as necessary, with equal parts of
clean water and Saab-approved coolant.
If the expansion tank is empty when coolant
is added, run the engine to normal temper-
ature and top up again, as necessary.
Coolant The cooling system is charged at the factory
with coolant containing a 50% concentra-
tion of a combined antifreeze and corrosion
inhibitor. A weaker mixture will result in
reduced anticorrosion protection. For pro-
tection against freezing in very cold
weather, a stronger concentration will be
needed.
A 60% concentration of antifreeze will pro-
vide protection at temperatures down to
-58 F (-50°C).The corrosion-inhibiting properties of the
coolant deteriorate over time, but
Saab-approved coolant can be used for
year-round protection. Change the coolant
as specified in the service program and use
only Saab-approved coolant – other makes
may need changing more frequently and
may damage the system.

WARNING
 Proceed with caution if the radiator is
boiling when you open the hood.
Never remove the expansion-tank
filler cap when the radiator is boiling.
Loosen the cap carefully, and let the
engine cool before removing the cap.
 The cooling system is pressurized –
hot coolant and vapor can escape
when the filler cap is released.
NOTEAlways mix the antifreeze with the
appropriate volume of water before
adding it to the cooling system.
If pure antifreeze is added, the engine
could still freeze and be damaged. This is
because the antifreeze will not mix
properly with the coolant before the
thermostat has opened to allow full
circulation.

175 Car care and technical information
Changing the coolant (Usually carried out as part of the Saab orig-
inal service by an authorized Saab dealer)
1 If the engine is hot, open the expan-
sion-tank filler cap carefully to release
the pressure, but do not remove it com-
pletely. Place a suitable receptacle
under the radiator and undo the drain-
cock.
2 Remove the filler cap on the expansion
tank.
3 The system takes about two minutes to
drain. Close the draincock.
4 Mix the antifreeze and water to the
required strength in a suitable container.
Use only Saab-approved coolant.
5 Add the coolant slowly to the expansion
tank. This will take about two minutes,
as the air needs time to escape.
6 Screw on the filler cap and fully tighten
the drain cook. Run the engine to normal
temperature. Top up the coolant, as nec-
essary, until the level is just below the
MAX mark on the tank.
7 Check the coolant again after a few days
and top up as necessary.
Brake and clutch fluid Checking the fluid level The combined brake and clutch-fluid reser-
voir is transparent to facilitate checking of
the fluid level.
WARNING
Brake fluid deteriorates as it becomes
old. Because it is hygroscopic, it absorbs
water from the air and, in time, could allow
vapor to form in the brake system, thus
reducing its performance. It is therefore
important that brake fluid be changed reg-
ularly, as specified in the service pro-
gram.

221 Maintenance and owner assistance
Saab Original Service Program M2000 USA, Canada, 9-5 Models)* These are the minimum required Emission Control System maintenance steps. Saab urges that all recommended maintenance procedures be performed
according to this program.
(a.) Engine oil and filter should be changed at least once a year. Intermediate oil and filter changes (halfway between indicated intervals) suggested for
cars primarily used for driving in dense city traffic or for repeated short trip operation without sufficient warm up.
*** Camshaft drive belt replacements (V6) prior to 100,000 miles will be performed at no charge by an authorized U.S. or Canadian Saab dealer.
** Service intervals:
Refer to the Warranties & Service Record Book for service intervals beyond 100,000 miles (160,000 km).Service Intervals **

Afterheater, V6-engine carsThe afterheater enables a comfortable temperature to be main-
tained inside the car even after the engine has been switched off.
The heater can be activated up to 10 minutes after the engine has
stopped, although the coolant temperature must be at least 40°C for
the heater to operate.
To start the heater:
1 The ignition should be OFF.
2 Press and hold the AUTO button on the ACC panel for about a
second, until a chime is sounded and the following appears on
the SID:
”AFTERHEATER
ACTIVATED”.
After five seconds, the SID will indicate how much heat is available
(0 – 100%).
To switch off the heater:
1 Press the OFF button on the ACC panel.
The heater will also be switched off if the ignition is turned ON. The following settings will be in force when the heater is running:
 Air distribution in AUTO mode.
 Recirculation not active but can be selected manually.
 Fan speed is automatic and cannot be changed.
 Only the fan speed is shown on the display. If AUTO is pressed,
the system selections will be indicated.
The following controls do not operate while the afterheater is on:
 Rear-window heating.
 ECON.
 User presets.
Some of the functions can be reprogrammed. For further informa-
tion, please consult your Saab dealer (see page 237).
