170 Car careEngine 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 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.
 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.

171 Car care
ORVR (Onboard Refueling Vapor
Recovery)All hydrocarbons formed when refuelling
will be recovered by the car and not
released into the atmosphere. The hydro-
carbons are absorbed in an evaporative
emission canister. When the engine is sub-
sequently started, the evaporative emission
canister is gradually purged as air is sucked
into it through a shut-off valve. The hydro-
carbon/air mixture passes through the evap
canister purge valve and into the engine
where it is burned. "Refueling", see page
138.
NOTEThe Trionic engine management system
continuously monitors the operation of
these systems and has on-board diag-
nostic capabilities (OBD II). If the 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 Saab
dealer as soon as possible.

172 Car careEngine oilChecking the fluid level Regularly check the oil level in the engine.
Do this with the car standing on level ground
with the engine warm, 2-5 minutes after it
has been turned off. Take the dipstick out
and wipe it off with a clean rag before carry-
ing out the check.
The level must not be below the MIN mark
on the dipstick, but nor should it be above
the MAX mark. Excess engine oil could
result in abnormal oil consumption.
The distance between MIN and MAX corre-
sponds to a volume of about one quart.
When necessary, add oil of the recom-
mended grade via the dipstick pipe. Make
sure that the cap of the dipstick is screwed
on properly after the check. Oil changingThe engine oil must be changed in accor-
dance with the service program, see page
215.
Oil volume and grade, see page 223.
Oil changing should be carried out on a
warm engine. 1 Unscrew the drain plug in the bottom of
the sump and leave the oil to drain into
an oil tray or other suitable receptacle for
at least ten minutes. Take care, as the oil
may be hot.
2 After the oil has been drained, unscrew
and remove the oil filter.
3 Fit a new filter and tighten it by hand.
4 Refit the drain plug with a new washer.
5 Add new oil.
Run the engine to normal temperature and
check the oil level.

Transmission fluidManual transmissionCheck and top up the fluid in accordance
with the service program.
If original fluid cannot be obtained for top-
ping up, Dexron III (synthetic fluid) auto-
matic transmission fluid can be used. If so,
the car should be taken to an authorized
Saab dealer as soon as possible to have the
reason for low fluid level corrected and orig-
inal fluid installed.Automatic transmissionCheck the fluid level as follows:
1 Park the car on level ground and apply
the parking brake. The automatic trans-
mission fluid must be at normal running
temperature, approximately 175°F
NOTEChange of engine oil and oil filter may be
required more frequently (5000-mile
intervals (8,000 km)) if any one of the fol-
lowing conditions apply to the car:
 Most trips are less than 5 to 10 miles (8
to 16 km). This is particularly important
when outside temperatures are below
freezing.
 Most trips include extensive idling
(such as frequent stop-and-go driving).
 Most trips are through dusty areas.
 You frequenty tow a trailer or use a car-
rier on top of your vehicle.
 If the vehicle is used for delivery ser-
vice, police, taxi or other commerical
applications.
WARNING
 Prolonged and repeated exposure of
the skin to engine oil can cause seri-
ous skin disorders.
 Avoid prolonged skin contact when-
ever possible. Wash the affected area
thoroughly with soap and water after
any contact.
 Keep oil out of reach of children.
 Do not touch the turbocharger or
manifold. These get very hot when the
engine has been running.
 Do not spill oil on hot parts of the
engine as this could cause a fire.
 Protect the environment. Do not dis-
pose of oil in the ground or down a
drain. Dispose of all used oil and oil fil-
ters at an appropriate disposal facility.

(80°C). This can be achieved by driving
the car for about 30 min on the open
road.
2 With the engine idling, move the selector
lever to D and wait for at least
15 seconds. Next, move the selector
lever to R and wait for 15 seconds again.
Finally, move the selector lever to P. Let
the engine idle.
3 Wipe the dipstick clean with a lint-free
cloth and put it back.
4 With the fluid at normal temperature, the
level should be between the MAX and
MIN marks on the dipstick. Top up, as
necessary, with Texaco Texamatic
Dexron III automatic-transmission fluid,
adding it through the dipstick pipe. The
distance between the MIN and MAX
marks on the dipstick corresponds to a
volume of approximately 0.4 qts
(0.4 litre).
If the outside temperature is below 50°F
(10°C), the fluid will not reach the specified
temperature of 175°F (80°C). In this case,
the correct fluid level may be 0.8 in (20 mm)
below the MAX mark.
CoolantThe expansion tank is transparent, to facili-
tate checking. The level must be a little
under the mark ”KALT – COLD” on the tank
when the engine is cold. If the SID message
"FILL COOLANT FLUID" is displayed, the
level in the expansion tank should be
checked. Top up as necessary with equal
parts of clean water and coolant. Use only
coolant approved by Saab.
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 filled 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 coolant
approved by Saab can be used for
year-round protection. Change the coolant
as specified in the service program (page
215) and use only coolant approved by
Saab – other makes may need changing
more frequently and may damage the sys-
tem.
NOTEIf there is a burnt smell or the fluid is black,
change the fluid as soon as possible.

175 Car care

Changing the coolant(Usually carried out as part of the Saab
original service by an authorized Saab
dealer)
1 If the engine is hot, loosen the expan-
sion-tank filler cap a little to release the
pressure. Leave the cap in place.
2 Fit a suitable piece of hose onto the
nipple of the drain cock. Let the hose dis-
charge into a receptacle under the radi-
ator and open the drain cock, which is
located on the inside of the radiator
facing the engine bay.
3 Remove the filler cap on the expansion
tank.
4 In a couple of minutes the system will be
empty. Close the drain cock. 5 Mix antifreeze and water in a suitable
container. Use only Saab-approved
coolant.
6 Add the coolant slowly to the expansion
tank. This will take about two minutes,
as the air needs time to escape.
7 Screw the expansion-tank cap on and
run the engine to normal temperature.
Top up with coolant until the level is just
under the "KALT – COLD" mark on the
tank.
8 Check the coolant again after a few days
and top up as necessary.
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.
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.

176 Car careBrake- clutch fluid and
brake pads
Checking the fluid level The combined brake and clutch-fluid reser-
voir is transparent to facilitate checking of
the fluid level.
The level should be between the MAX and
MIN marks. Top up, as necessary, with
DOT 4 fluid. Do
not
use DOT 5 brake fluid.
Use only new brake fluid from a sealed con-
tainer.
Check that there are no leaks in the brake
system.
Changing of the brake fluid should be
carried out by an authorized Saab dealer.
The vehicle´s regular braking system is
adjusted automatically, but the parking
brake has to be adjusted manually. This
work, involving adjustment of the parking
brake cables and brake pads, must only be
carried out by an authorized Saab dealer.
It is not possible to detect, through abnormal
pedal or parking brake-lever travel, whether brake pads are worn and need replacing. It
is therefore essential that brake pads be
checked regularly, as specified in the ser-
vice program, see page 215.
Brake pad wear indicators The outboard brake pads on the front
wheels incorporate pad-wear indicators.
When the lining is down to 0.11 in (3 mm),
the pad will produce a screeching, squeal-
ing or scraping noise when the brakes are
applied. New pads should be installed with-
out delay.
Brake pads should only be changed by
an authorized Saab dealer. To ensure
optimum brake performance, use only
Saab original brake pads.
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, see page 215.
NOTEAvoid spilling brake fluid onto paintwork,
since it can cause the paint to bubble and
lift. If any brake fluid is spilled, the area
should be flushed with large quantities of
water as quickly as possible.
