2007 SAAB 9-3 engine

200 Starting and drivingUsing a battery charger3/starter
unitTo 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.
No other apparatus that are grounded or
connected to the mains must 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 connecting the
unit to the battery.
For long tripsBefore starting off on a long journey, it is
advisable to have your car inspected by
your Saab dealer.
Obtain a few important items to take along
on your journey, such as spare bulbs, wiper
blades, fuses, a drive belt (poly-V-belt) and
the like.
You can check some points yourself before-
hand:
Check that no oil or fuel leaks out of the
engine or gearbox/transmission.
Check the coolant and power steering
fluid levels. Check also for leaks.
Inspect the drive belt (poly-V-belt) and
replace if it shows any signs of wear.
Check the battery charge.
Check the tires for tread pattern and air
pressure, including the compact spare
tire.
Take an extra remote control and keep it
separate.
Check the brakes.
Check all bulbs.
Check for the presence of the tool kit and
jack in the car.

202 Car careHoodThe hood release handle is located on the
left under the instrument panel. Open the
hood in the following way:
1 Pull the release handle.
2 The hood moves to the half-locked posi-
tion and is stopped by a safety catch at
the front edge.
3 Press the lever of the catch upwards and
raise the hood.
When you close the hood you should drop it
from a height of about 12 inches (30 cm),
without slamming it.
EngineTurbo 4-cylinder engineThe engine is a transverse four-cylinder in-
line engine with twin overhead camshafts
and 16 valves.
The engine is equipped with two balance-
shafts that reduce engine vibrations 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. The effect occurs
twice in each revolution of the engine, coun-
teracting the vibration from its moving parts,
and at the same time reducing unwanted
engine noise.
The gearbox, located on the right (viewed
from the front), is integrated with the engine.Turbo V6 engineThe V6 engine is a turbocharged V6 engine
produced completely of aluminium with 60°
between the cylinder banks, 4 valves per
cylinder, 2 camshafts per bank.
The camshafts are driven via a chain trans-
mission. The engine is equipped with a
turbo whose turbine collects exhaust pres-
sure from both banks of cylinders.

sumption and low emission levels the

engine is equipped with CVCP (Continuous
Variable Cam Phasing). This means that
the engine’s intake camshafts can be
adjusted to achieve optimum functionality.
The switches are hydraulic.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 in the engine bay.
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 system, 4-cyl
engineThe 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.
WARNING
Engine exhaust, some of its constituents,
and certain vehicle components contain
or emit chemicals known to the State of
California to cause cancer and birth
defects and reproductive harm. In addi-
tion, certain fluids contained in vehicles
and certain products of component wear
contain or emit chemicals known to the
State of California to cause cancer and
birth defects or other reproductive harm.

system, V6 engineThe Bosch ME9 engine management
system is a system that combines sequen-
tial multiport fuel injection, electronic distrib-
utorless ignition and turbocharger boost
pressure control into one system and intake
camshaft phasing control.
The ME9 engine control module (ECM)
monitors many different engine parameters
such as:
Charge air pressure.
Intake air temperature.
Crankshaft position.
Engine coolant temperature.
Throttle position.
The oxygen content of the exhaust gases.By processing all of this information, the
ME9 system can control fuel injector open-
ing duration, ignition timing, intake camshaft
phasing and turbocharger boost pressure to
provide excellent engine performance while
maintaining low emissions and fuel con-
sumption.
ORVR (Onboard Refueling Vapor
Recovery)All hydrocarbons formed when refueling will
be recovered by the car and not released
into the atmosphere. The hydrocarbons are
absorbed in an evaporative emission canis-
ter. When the engine is subsequently
started, the evaporative emission canister is
gradually purged as air is sucked into it
through a shut-off valve. The hydrocar-
bon/air mixture passes through the evap
canister purge valve and into the engine
where it is burned. “Refueling”, see
page 157.
When refueling, make sure you screw the
filler cap on and keep turning until it has
clicked 3 times.
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) light in
the main instrument illuminates, 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 workshop as
soon as possible. We recommend that
you contact a Saab dealer.

207 Car care
Engine oilChecking the oil levelCheck the engine oil level regularly.
1 Park the car on a level ground.
2 Switch off the engine and wait for
2–5 minutes. The engine should be at
normal operating temperature.
3 Take the dipstick out and wipe it off with
a clean rag before carrying 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 the MIN and MAX
marks is equivalent to 1.0 qt (1.0 l).4-cyl engine: The engine oil level is
checked each time the engine is started. If
the oil level is low, the following message
appears on the SID:
If this occurs the oil level must be checked
first. If the level is too low then it must be
topped up.V6 engine: The engine has an oil level
sensor that checks the oil level when the
engine is running. If the oil level drops too
low, the following message appears on the
SID:
If this occurs the oil level must be checked
first. If the level is too low then it must be
topped up.NOTICEToo high oil level can damage the engine.
Low engine oil level.
Fill oil now.
Low engine oil level.
