165 Starting and driving
If the diagnosis function detects a fault in the
engine management system, the light
"Engine malfunction (CHECK ENGINE)" in
the instrument panel will come on (see
page 85). Have the car checked at a work-
shop as soon as possible. We recommend
that you contact a Saab dealer.
Important considerations with
catalytic convertersThe catalytic converter is an emission con-
trol device incorporated in the car’s exhaust
system. It consists of a metal canister with a
honeycomb insert, the cells of which have
walls coated in a catalytic layer (precious
metal alloy).
To ensure that the catalytic converter con-
tinues to function properly, and also to avoid
damage to the converter and its associated
components, the following points must be
observed: Have the car serviced regularly in accor-
dance with the service program.
 Always be alert to any misfiring of the
engine (not running on all cylinders) and
any loss of power or performance. At the
first sign of a malfunction, reduce speed
and take the car to a workshop. We
recommend that you contact a Saab
dealer.
 If the engine fails to start (in severe cold or
if the battery is flat), the car can be bump
started (manual transmission only) or
started using jump leads to a donor
battery. However, as soon as you have
started the engine, it is important that it
runs on all cylinders. If it is misfiring, allow
it to idle for up to 5 minutes to give it time
to settle and run smoothly. If, after this
time, the engine still fails to run properly,
switch off the engine to avoid serious
damage to the catalytic converter. We
recommend that you contact a Saab
dealer for advice.
NOTICEIf "Engine malfunction (CHECK
ENGINE)" warning light starts to flash
(indicating that the engine is misfiring and
the catalytic converter can be damaged),
ease off the accelerator slightly. The light
should go out or start to shine constantly.
If the light continues to flash despite
easing off the accelerator, you may
continue to drive the car but at the mini-
mum throttle permitted by the current traf-
fic situation. Have the car checked as
soon as possible. We recommend that
you contact a Saab dealer.
NOTICEUse only unleaded gasoline. Leaded
gasoline is detrimental to the catalyst and
oxygen sensor and will seriously impair
the function of the catalytic converter.

166 Starting and driving Never park the car on dry grass or other
combustible material. The catalytic
converter gets very hot and could there-
fore start a fire.
 Never drive off if the engine is misfiring.
 If you bump start the car when the engine
is already at normal working temperature,
the engine must start to run on all cylin-
ders. Abort bump starting if the engine
fails to start immediately.
Failure to strictly follow these instructions
can result in damage to the catalytic con-
verter and associated components, and
could represent a breach of the warranty
conditions.
NOTICEIf the car runs out of gas, air may be drawn
in with the fuel, which, in turn, can cause
the catalytic converter to be damaged by
overheating.
WARNING
If the engine is being run with the car on a
rolling road or dynamometer, to ensure
adequate cooling, air must be blown into
the engine compartment and under the
car at a rate equivalent to the ram-air
effect that would obtain at the corre-
sponding road speed.

174 Starting and drivingPark Brake Shift LockThe transmission has a security function
known as Park Brake Shift Lock. To move
the gear selector lever out of the P or N posi-
tion, the gear selector lever detent (catch)
must be pressed in at the same time as the
brake pedal is held depressed.
The detent button on the selector lever has
to be pressed in before the lever can be
moved between certain positions.
Temporary override of Park Brake Shift
Lock, see page 176.
Adaptive gear change patternsThe adaptive gear change pattern function
adapts gear changing to the prevailing driv-
ing conditions. The transmission control
module senses the engine load, vehicle
speed and temperature of the transmission.
A suitable gear change pattern is then
selected automatically to avoid unneces-
sary gear changes and undesired increases
in transmission temperature.
Certain variants use a special change pat-
tern for the first few minutes after a cold start
so that the catalytic converter reaches its
working temperature more quickly.
Thermal transmission protectionThe transmission has built-in protection
against overheating. This protection is pro-
vided by the control module, which changes
gear change patterns.
1 If the temperature of the transmission
fluid exceeds 257°F (125°C), the gear
change pattern is changed.
2 If the temperature of the transmission
fluid exceeds 275°F (135°C), the gear
change pattern is again changed.
3 If the temperature of the transmission
fluid exceeds 302°F (150°C), engine
torque will be limited to 147 ft.lbs.
(200 Nm).
The following message is shown on the SID:
If this message appears, stop the car as
soon as it is safe to do so and allow the
engine to idle until the message has gone
out. The selector lever should be in
position P.Gearbox too hot.
Make a safe stop.
Open hood to cool down.

187 Starting and driving
Parking brakeThe parking brake lever is situated between
the front seats. The brake acts on the rear
wheels. When the parking brake is applied,
the indicator light on the main instru-
ment panel will come on.
To release the parking brake, lift the lever
slightly, pull the release button on the under-
side of the lever and lower the lever.
If conditions allow, it is best if the brake
pedal is not depressed, or only depressed
as little as necessary so as to stop the car
from rolling, when the parking brake is
applied.
To facilitate releasing the parking brake,
depress the brake pedal. This is especially
appropriate if the car is standing on a hill.If the parking brake is applied when the car
starts off, the following message will appear
on the SID:

driving.
 Grasp the parking brake lever in such
a way that no fingers get trapped when
you release the parking brake.
Release parking brake.
WARNING
Never leave children or pets unat-
tended in the car. In warm, sunny
weather, the temperature inside the
car can reach 160–180°F (70–80°C).
 Park where the vehicle will not create
an obstruction or a hazard to other
road users.
 Do not park on dry grass or other
combustible material. The catalytic
converter gets very hot and could start
a fire.

215 Car care
EngineTurbo petrol 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.Petrol engine, V6The 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.
To obtain optimum performance, fuel con-
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.
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.
