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.

204 Car careBosch ME9 engine management
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.

208 Car careMake sure you screw on the oil filler cap
properly after topping up the oil to avoid
running problems.
It is normal for an engine to consume a cer-
tain amount of oil. It is therefore often nec-
essary to top up the oil between services.
Check the engine oil level regularly.
During the Break-in Period (approx.
3,000 miles or 5,000 km) and when driving
at high speeds or with a trailer, the oil con-
sumption may be higher than normal.NOTICEChange of engine oil and oil filter may be
required more frequently if the car is
being used under certain conditions, see
page 275.
WARNING
Prolonged and repeated exposure of
the skin to engine oil can cause seri-
ous skin disorders. Avoid prolonged
skin contact whenever possible.
Used engine oil contains chemicals
that have caused cancer in laboratory
animals. Always protect your skin by
washing thoroughly with soap and
water.
Keep oil out of reach of children.
Do not touch the turbocharger or
exhaust 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
dispose of oil into the ground or down
a drain. Dispose of all used oil and
oil filters at an appropriate disposal
facility.
NOTICE Do not run the engine with the oil level
too low.
Change engine oil and oil filter in
accordance with the service
programme
Only use the recommended type of oil.
Observe the above three points to avoid
serious damage to the engine.
For oil volumes and grades, refer to
page 284.
