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.

172 Car care and technical informationOil changingThe engine oil must be changed in accor-
dance with the service program, see page
218.
Oil volume and grade, see page 229.
Oil changing should be carried out on a
warm engine. 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.
After the oil has been drained, unscrew and
remove the oil filter. Fit a new filter and
tighten it by hand before adding new oil.
Refit the drain plug with a new washer.
Run the engine to normal temperature and
check the oil level.
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 frequently 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 commercial
applications.

173 Car care and technical information
Transmission fluidManual transmission Check and top up the fluid in accordance
with the service program.
If original fluid cannot can be obtained for
topping up (see page 231), automatic trans-
mission fluid Dexron III (synthetic 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 cor-
rected and original fluid installed.Automatic transmission Check the fluid level as follows:
1 Stand the car on level ground and apply
the handbrake. The automatic transmis-
sion fluid must be at normal running tem-
perature, approximately 175°F (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
(mineral oil-based), adding it through
the dipstick pipe. The distance between the MIN and MAX marks on the dipstick
corresponds to a volume of approxi-
mately 0.4 qts (0.4 liter).
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.
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.
NOTEIf there is a smell of burning fluid or the
fluid is black, change the fluid.

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.

176 Car care and technical informationThe 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.
The brake fluid level will fall somewhat as
the brake pads wear. The MAX level in the
reservoir corresponds to the amount of
brake fluid required with new brake pads. If
the fall in fluid level is moderate, due to
normal brake pad wear, topping up is not
necessary.
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.
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 fitted without
delay.
Brake pads should only be changed by
an authorized Saab dealer. To ensure
optimum brake performance, use only
Saab original brake pads.
Power steering fluidCheck the level of the power steering fluid in
the reservoir regularly, in accordance with
the service program.
The wheels should point forward during the
check.
Clean around the cap before it is
unscrewed. Clean the dipstick. Screw in the
cap completely again before checking the
level.
The oil should lie between the MAX and MIN
marks when the oil temperature is about
70°F (+20°C). If the oil is colder the level can
be lower, and in higher temperatures the
level can be higher, both of which are
acceptable.
Top up with ”Power Steering Fluid
CHF 11S” (part number 3032380).

200 Car care and technical informationUniform Tire Quality Grading (US)Quality grades can be found where applica-
ble on the tire sidewall between tread shoul-
der and maximum section width. For exam-
ple:
Treadwear 200 Traction AA
Temperature ATreadwearThe treadwear grade is a comparative
rating based on the wear rate of the tire
when tested under controlled conditions on
a specified government test course. For
example, a tire graded 150 would wear one
and one half (1 1/2) times as well on the gov-
ernment course as a tire graded 100. The
relative performance of tires depends upon
the actual conditions of their use, however,
and may depart significantly from the norm
due to variations in driving habits, service
practices and differences in road character-
istics and climate.
TractionThe traction grades, from highest to lowest,
are AA, A, B and C. These grades represent
the tire’s ability to stop on wet pavement as
measured under controlled conditions on
specified government test surfaces of
asphalt and concrete. A tire marked C may
have poor traction performance.
Wear indicatorsThe tires incorporate wear indicators in the
form of smooth, treadless strips across the
width, which become visible when only
1.6 mm of tread remains. As soon as the
indicators become visible, new tires should
be fitted without delay.
Make sure you are familiar with the legal
limit for minimum tread depth in your
country and also any regulations gov-
erning the use of winter tires.
WARNING
The traction grade assigned to a tire is
based on straight-ahead braking, traction
test and does not include acceleration,
cornering, hydroplaning or peak traction
characteristics.

207 Car care and technical information
Maintenance  The drive belt for the compressor should
be inspected under the regular service
program.
 Clean dirt and insects away from the con-
denser and radiator to prevent clogging.
When washing the car, use the hose to
spray the radiator and condenser (located
forward of the radiator) from both sides
(both from the front of the car and from
inside the engine bay). Do not use a pres-
sure washer.
Caution: Do not use the hose when the
engine is hot.Other than in extremely cold weather, do not
screen the radiator, e.g. with netting, as this
will greatly diminish its cooling capacity.
Note: The A/C system will only operate
when the outdoor temperature is above the
freezing point (0°C, 32°F).
Safety beltsRegularly check the function of the safety
belts as follows:
 Hold the diagonal strap and pull it sharply.
The safety belt should lock and it should
not be possible to withdraw it further.
Check the anchorage points in the floor.
They must not have suffered rust damage.
There must be no frayed threads in the web-
bing.
Safety belts must not come into contact with
substances such as polishes, oils or other
chemicals. If the straps are dirty, wash them
with warm water and a detergent or have
them replaced.
WARNING
If the car is involved in a collision, the
safety belts, belt pretensioners and other
components must be inspected by an
authorized Saab dealer.
Never make any alterations or repairs to
the safety belt yourself but visit an autho-
rized Saab dealer.

214 Car care and technical information
Headlamp aimingThe vehicle is equipped with vertical and
horizontal aim indicators. The aim has been
preset at the factory and should normally
not need further adjustments. This is true
even though your vertical and horizontal
aim indicators may not fall exactly on the "0"
(zero) marks on their scales.
If your headlamps are damaged in an acci-
dent, the headlamp aim may be affected. If
you believe your headlamps 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 headlamps
as described in the following procedure.
WARNING
Before checking/adjusting the headlamp
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.
