2005 SAAB 9-5 engine

175 Starting and driving
4 Open the hood and locate the battery.
Find the positive (+) and negative (–) termi-
nals on the battery.5 Check that the jumper cables do not
have loose or missing insulation. If they
do, you could get a shock and also the
vehicles could be damaged.
Before you connect the cables, here are
some basic things you should know.
Positive (+) will go to positive (+) and
negative (–) will go to a major metal
engine part with a good ground. Do not
connect (+) to (–) or you will get a short
that could injure you or would damage
the battery and maybe other parts as
well.
6 Connect the red positive (+) cable to the
positive (+) terminal of the vehicle with
the discharged battery.
7 Do not let the other end touch metal.
Connect it to the positive (+) terminal of
the good battery. Use a remote positive
(+) terminal if the vehicle has one.
8 Now connect the black negative (–)
cable to the good battery’s negative
terminal.NOTICEIf you leave your radio on, it could be
badly damaged. The repairs would not be
covered by your warranty.
WARNING
An electric fan can start up even when the
engine is not running and can injure you.
Keep hands, clothing and tools away from
any underhood electric fan.
WARNING
Using a match or flame of any kind near a
battery can cause battery gas to explode.
You can suffer burns or be blinded. Use a
flashlight if you need more light.
Be sure the battery has enough water.
The battery installed in your new Saab
has filler caps. Be sure the right amount
of water is there. Add distilled or boiled
water if the level is too low. If you don’t,
explosive gas could be present.
Be sure the electrolyte in the battery is not
frozen. Discharged batteries will freeze.
When connecting jumper cables to a
frozen battery, gas from the chemical
reaction inside the battery can build up
under the ice and cause an explosion.
Battery fluid contains acid that can burn
you. Do not get it on you. If you acciden-
tally get it in your eyes or on your skin,
flush the area with water and get medical
help immediately.

176 Starting and driving9 Attach the cable at least 18 inches
(45 cm) away from the discharged bat-
tery, but not near engine parts that
move. To avoid an arc which could deto-
nate the hydrogen gas around the bat-
tery, the final connection must be at least
18” from the battery.
10 Start the vehicle with the good battery
and run the engine for a while.
11 Try to start the vehicle with the dischar-
ged battery. If it does not start after a few
tries, it probably needs service.
12 Remove the cables in reverse order to
prevent electrical shorting. Take care
that they do not touch each other or any
other metal.
Charging the battery/Jump
startingTo avoid damaging the car’s electrical
system and electronics, the following rules
must be followed when charging the battery
or jump starting the car.
 If the charger or starter unit can be set to
different voltages (6V/12V/18V/24V), 12V
must be selected.
 Follow the manufacturer’s instructions
supplied with the charger or starter unit.
 Nothing that is plugged into an electrical
outlet should be connected to the car
during charging or jump starting.
 The charger or starter unit must under no
conditions produce a voltage greater
than:
 16V continuous
 18V for 60 min.
 If you are unsure about the charge rating
of the unit, disconnect the battery clamp
from the positive terminal before connec-
ting the unit to the battery.
WARNING
Do not let the other end touch anything
until the next step. The other end of the
negative cable
does not
go to the dead
battery. It goes to a major metal part with
a good ground on the engine of the
vehicle with the discharged battery.

180 Starting and drivingParking on a hillWhen parking on a steep hill, turn the front
wheels so that they will be blocked by the
curb if the car should move. Long-term parkingIf the car is not going to be used for some
time, e.g. 3–4 months, the following steps
are recommended:
 Run the engine to normal temperature
before long-term parking.
 Drain the washer-fluid reservoir and
hoses.
 Wash and wax the car. Clean the rubber
seals on the hood, luggage compartment
lid and doors, and lubricate them with gly-
cerol (glycerin).
 After washing the car, dry the brake discs
by taking the car out on the road and app-
lying the brakes a few times.
 Fill the fuel tank with fuel to prevent con-
densation forming in it.
 Top up the coolant and check the anti-
freeze before the onset of winter.
 Park the car in a dry, covered and well-
ventilated building. Leave the parking
brake OFF!
 Disconnect the negative (–) battery lead.
If frost is likely to occur during the long-
term parking, remove the battery and
store it away from the frost.
 Ideally, the car should be put up on blocks,
with the wheels off the ground. If this is not possible, inflate the tires to about 43 psi
(300 kPa).
 Leave all the windows open a crack and
cover the car with a fabric tarpaulin – not
one made of plastic.

1Pointing downhill and
against the curb– Turn the wheels into
the curb and edge the
car forward until the
wheels touch the curb.2
Pointing uphill and
against the curb– Turn the wheels away
from the curb and edge
the car back until the
wheels touch the curb.3
Pointing uphill or
downhill – no curb– Turn the wheels
towards the edge of the
road. If the car should
start rolling, it will not run
into the road.

184 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 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.

185 Car care and technical information
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 ope-
ning duration, ignition timing and turbochar-
ger boost pressure to provide excellent
engine performance while maintaining low
emissions and fuel consumption.
ORVR (Onboard Refueling Vapor
Recovery)Hydrocarbon vapors formed when refueling
will be recovered by the car and not rele-
ased into the atmosphere. The hydrocar-
bons are absorbed in a evaporative emis-
sion canister. When the engine is
subsequently started, the evaporative emis-
sion canister is gradually purged as air is
sucked into it through a shut-off valve. The
hydrocarbon/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.
Refueling, see page 138.
NOTICEThe Trionic engine management system
continuously monitors the operation of
these systems and has 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.

186 Car care and technical informationEngineThe 2.3-liter model is a transverse, 4-cylin-
der in-line engine with twin overhead cams-
hafts 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 coun-
ter-rotating shafts counteract the vibration
from the moving parts of the engine.
The transmission, located on the right (vie-
wed from the front), is integrated with the
engine. All models have front-wheel drive.
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 stan-
ding on level ground. Remove the dipstick
and wipe it clean before checking the level.
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 recommen-
ded grade via the dipstick tube.
