SAAB 9-5 2002 Owners Manual

191 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 (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.

192 Car care and technical informationORVR (Onboard Refueling Vapor
Recovery)Hydrocarbon vapors formed when refueling
will be recovered by the car and not
released into the atmosphere. The hydro-
carbons are absorbed in a 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.
When refueling, make sure you screw the
filler cap on and keep turning until it has
clicked at least 3 times. Otherwise, it is pos-
sible for the CHECK ENGINE light to illumi-
nate and a ”TIGHTEN FUEL FILLER CAP”
message to appear on SID.
Refueling, see page 152.
Engine2.3-liter engineThe 2.3-liter model is a transverse, 4-cylin-
der in-line engine with twin overhead cam-
shafts and 4 valves per cylinder.
This engine is equipped with balance shafts
that reduce engine vibration to a minimum.
The balance shafts are chain driven and
rotate at twice the speed of the crankshaft.
They produce forces and torques that are
opposed to those generated by the pistons
and connecting rods, an effect that occurs
twice for each revolution of the engine.
Engine noise is also reduced as the
counter-rotating shafts counteract the vibra-
tion from the moving parts of the engine.
The transmission, located on the right
(viewed from the front), is integrated with
the engine. All models have front-wheel
drive.
3.0t V6 engine The 3.0-liter engine is a transverse, V6
engine with each bank of cylinders having
double overhead camshafts and 4 valves
per cylinder.
The transmission, located on the right
(viewed from the front), is integrated with
the engine. All models have front-wheel
drive.

193 Car care and technical information
Engine oilChecking the oil level Check the engine-oil level regularly. This
should be done after the engine has been
run to normal temperature and then allowed
to cool for 2–5 minutes, with the car stand-
ing on level ground. Remove the dipstick
and wipe it clean before checking the level.
4-cylinder engine The oil level must not be allowed to drop
below the MIN mark on the dipstick, nor
should oil be filled beyond the MAX mark, as
this can lead to excessive oil consumption.
The distance between the MIN and MAX
marks on the dipstick corresponds to a
volume of approximately 1.05 qts (1 liter).
When necessary, add oil of the recom-
mended grade via the dipstick tube.
3.0t V6 engine The oil level must not be allowed to drop
below the MIN mark on the dipstick, nor
should oil be filled beyond the MAX mark, as
this can lead to excessive oil consumption.
The distance between the MIN and MAX
marks on the dipstick corresponds to a
volume of approximately 1.05 qts (1 liter).
When necessary, add oil of the recom-
mended grade via the dipstick tube.

194 Car care and technical informationOil changingThe engine oil must be changed in accor-
dance with the service program, see page
244.
Oil volume and grade, see page 251.
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 Fill with new engine oil.
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.

195 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 254), automatic trans-
mission fluid Dextron 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 parking brake. The automatic trans-
mission fluid must be at normal running
temperature, 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 Saab 3309 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 approximately 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. Used
engine oil is particularly flammable.
 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.

196 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 coolant does not normally have to be
changed during the service life of the car.
The type of coolant used has a reddish color
and should not be mixed with other types of
coolant. Saab Original coolant should be
used all year round. Only use coolant
approved by Saab.

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.
 Exercise care when adding coolant.
Coolant on hot surfaces constitutes a
fire risk.
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.

197 Car care and technical information
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.
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.
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.
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.
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.

198 Car care and technical informationPower 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 8996860).
Air filter
WARNING
Do not fill the power steering fluid to
above the MAX mark. Too much fluid can
result in leakage.
Power steering fluid on hot engine com-
ponents constitutes a fire risk.
WARNING
For Service and Repair, parts equivalent
to those used by Saab should be used.
Be aware that some non standard
replacement parts may put you in an
unsafe condition, even if they might fit.

199 Car care and technical information
BatteryThe battery is provided with a cover to
protect it from radiated heat. If the battery is
exposed to high temperatures, its life will be
shortened. To remove the cover, release
the two clips along its long sides.
The cover fits the standard battery installed
in the car. If a new battery is to be fitted,
make sure that its dimensions are the same
as the standard one.
The battery is maintenance free and should
be changed if the electrolyte level is too low.
The indicator on the top side of the battery
will be white if the battery needs replacing.The fluid level and the charge level should
be checked regularly.

If frequent short journeys are made, the bat-
tery may need to be given a booster charge.
This can be done either using a battery
charger or by taking the car for a long run.
A car with a standard equipment specifica-
tion and a fully charged battery can be left
for up to 40 days and still have a sufficient
charge for starting. If extra equipment is fit-
ted, such as a car phone, the charge may
only be sufficient for about 15 days.
WARNING
 The battery emits hydrogen which,
when mixed with the oxygen in the air,
forms a highly explosive gas. Avoid
causing sparks and keep open flames
well away from the vicinity of the bat-
tery.
 The battery contains corrosive sulfuric
acid. Always wear a face mask or
goggles when working on the battery.
 If battery acid gets into the eyes or
splashes the skin or clothing, wash
affected area liberally with water.
If acid gets into the eyes or a large
quantity makes contact with the skin,
seek medical help.
NOTEA discharged battery can freeze and frac-
ture. Batteries should therefore always be
stored away from frost.

200 Car care and technical informationCharging/replacing the batteryConnect the positive lead to the positive (+)
battery terminal (red), and the negative lead
to a good ground point, e.g. the lifting lug at
the front of the engine.
To remove the battery, always disconnect
the negative (black) lead first and reconnect
it last when fitting the new battery.
The battery size must comply with DIN
53735 MFI 230/2.16.

NOTETo avert the danger of short-circuiting
between the positive (+) terminal on the
battery and the inlet manifold on the
engine, always disconnect the negative
(-) battery lead first and reconnect it last.
NOTE Never reverse the polarity of the bat-
tery by connecting the leads to the
wrong terminals. The red, positive
lead connects to the positive (+) termi-
nal, and the black, negative lead to the
negative (-) terminal.
 Serious damage can be done to the
car’s electrical system if a battery or
alternator lead is disconnected while
the engine is running.
 The nut on the battery clamp should
be tightened to a torque of 10 Nm.
