The A/C compressor will not
activate unless the outdoor
temperature is above 55
°F
(+13°C).
–This function saves fuel by
delaying the activation of the
A/C compressor. However,
in wet weather it is advisable
to have the A/C compressor
running when outdoor tem-
peratures are below
57°
(+14°C), as the A/C system
reduces the likelihood of the
windows’ fogging up.

Recirculation will be
switched on if the speed of
the car is less than 6 mph (10
km/h) and will be switched off
when the speed has risen
above 20 mph (30 km/h), but
not if the ECON mode has
been programmed according
to ”Programming II”.
–This function is useful to
prevent fumes being drawn
into the car in traffic jams.
Recirculation is
switched on about
45 seconds after start-
ing if the outdoor tem-
perature is above 86
°F

selected temperature
for the cabin is well
below the actual tem-
perature in both tem-
perature zones.
The heating will come on
about five seconds after the
engine has started if the out-
door temperature is below
41°F (+5°C).

Audio System speakers.
 TELEPHONE appears on the SID when
phone in use. Volume level for ongoing conversation
can be adjusted by volume controls on
steering wheel or on Audio System
module (see also ”Volume-preset mode”,
page 97).
 If the sound is distorted, adjust by means
of the volume control on
telephone set
.
 Phone battery charging when phone is in
its cradle.
Please refer to the instructions supplied with
the phone for details of how to make and
receive calls. In order to fully utilize the
hands-free function, certain circuits must be
available from the telephone to be installed.
Your authorized Saab dealer has this infor-
mation available.
WARNING
To prevent crashes while using a cell
phone:
 Don’t use the phone in distracting traf-
fic situations. Turn it off if traffic is
heavy.
 Dial sensibly, at a stoplight or safely off
the road.
 Consider installing hands-free or
speaker phone.
 Avoid stressful and intense phone
conversations.
 Acquaint yourself with the legal provi-
sions governing the use of car phones
while driving.
 Do not use the phone when refueling
the vehicle. Gasoline fumes are highly
explosive.
NOTEThe A-pillar area (area beside the wind-
shield) and the headlining of your Saab
contain padding designed to reduce head
injuries. No modifications to these areas
should be made unless done by your
authorized Saab dealer.

104 Saab 9-5 Audio SystemMobile phones and
communications radios Mobile phones and communications radios
that do not have a separate external
antenna radiate an electromagnetic field
inside the car.Saab therefore recommends that a car
phone/radio transmitter should always be
connected to an external antenna.
An external antenna also provides
improved transmission/reception and a
greater range. Roof loads can negatively
affect telecommunication.
Mobile phones and communications radios
that are not supplied as standard equipment
by Saab can interfere with the car’s electri-
cal system and cause spurious fault codes
to be generated.

Fault codesThe Audio System has a built-in diagnostics
function. If a fault is detected, a fault code is
generated to help dealer technicians to
diagnose the fault. Below are the codes for
some faults that you might be able to rectify
yourself.
WARNING
The electromagnetic field produced, for
example, by a mobile telephone in the
passenger compartment may be detri-
mental to health. We therefore recom-
mend the use of an external antenna.
Do not use the phone when refueling with
gasoline. Gasoline fuels are highly explo-
sive.NOTEThe electromagnetic field can cause
interference to other electrical systems in
the car, such as the Audio System.
WARNING
Always consult an authorized Saab
dealer for installation guidance.
If you feel that any of the warnings or fault
indications are unclear, have the equip-
ment checked by an authorized Saab
dealer.
NOTEGreat care should be exercised in trying
to rectify a fault. If you are at all unsure,
contact an authorized Saab dealer.

150 Starting and drivingIt is possible for air to enter the lubricating
system in conjunction with an oil or oil-filter
change, or if the car has been stored for
some time. This air can cause the hydraulic
cam followers to emit a ticking noise, which
can persist for up to 15 minutes after start-
ing. Although this is quite normal and does
not indicate any malfunction, it is advisable
not to exceed 3,000 rpm before the noise
has disappeared.
The hydraulic cam lifters are completely
service free; the valve clearance is set up at
the factory and will not need any subse-
quent adjustment.
Starting the engineAvoid racing the engine or putting a heavy
load on it before it has warmed up. Drive
away as soon as the oil warning light has
been extinguished to enable the engine to
attain its normal temperature as quickly as
possible.
The engine has an automatic choke and
should be started as follows:
Cars with manual transmission
To start the engine the clutch pedal must
be fully depressed.
1 Depress the clutch pedal fully but do not
touch the accelerator.
2 Start the engine. Let the ignition key
spring back as soon as the engine has
started and is running smoothly – at very
low temperatures, you may need to run
the starter for up to 25 seconds. Wait
20-30 seconds before running the
starter again, to give the battery time to
recover.
Let the engine idle for about 10 seconds. Do
not open the throttle wide for at least
2-3 minutes after starting. Cars with automatic transmission
1 The selector lever must be in the P or N
position.
2 Keep your foot on the brake pedal.
3 Start the engine. Let the ignition key
spring back as soon as the engine has
started and is running smoothly – at very
low temperatures, you may need to run
the starter for up to 25 seconds. Wait
20-30 seconds before running the
starter again, to give the battery time to
recover.
Let the engine idle for about 10 seconds. Do
not open the throttle wide for at least
2–3 minutes after starting.
Useful tips on cold climate starting If the engine has failed to start after several
attempts in very cold weather, press and
hold the accelerator down to the floor and
run the starter for 5–10 seconds. This will
prevent the engine being flooded (exces-
sively rich fuel-air mixture).
Now start the engine in the normal way – do
not touch the accelerator.
If the engine stalls immediately after starting
(e.g. if the clutch was released too quickly),
do not touch the accelerator when restarting
the engine.  The tail pipe of the exhaust system
can become very hot during driving.
Bear this in mind when loading and
unloading the car.
 Do not rest or sleep in the car when
parked with the engine running. There
is a risk of depressing the accelerator
which could lead to engine damage.

151 Starting and driving
Limp-home modeThe car’s engine-management system
includes a diagnostic function that checks
numerous internal functions after the
engine has been shut off. If a fault is
detected in the throttle system, the
engine-management system puts the throt-
tle system into the limp-home mode. This
limits idling control, disables the cruise-con-
trol system and limits the capacity of the A/C
compressor.
If the limp-home mode is in operation
(”Engine malfunction (CHECK ENGINE)”
light on, see below) and the outside temper-
ature is close to or below freezing, you may
need to use some throttle on starting (some
pressure on the accelerator).
If the diagnostic system has detected a fault
in the engine-management system, the
”Engine malfunction (CHECK ENGINE)”
light on the main instrument panel will
come on (see page 51), indicating that you
should have the car checked as soon as
possible by an authorized Saab dealer.
Important
considerations for
drivingThe engine-management system in the
Saab 9-5 is called Saab Trionic T7. The
system manages the ignition, fuel injection
and turbo boost pressure.
The Trionic T7 system developed by Saab
is an intelligent engine-management
system designed to achieve optimum driv-
ability under differing driving conditions.
The system makes adjustments automati-
cally, for instance, if the car is being driven
at altitude (oxygen-deficient air), for differ-
ent grades of fuel (AON 87–93) and for dif-
ferent load conditions.
1 Starting and driving
 Refrain from using full throttle before
the engine has warmed up (before
needle in mid-range on temperature
gauge).
 A safety function prevents the engine
from revving faster than 6,000 rpm by
limiting the induction air.
2 Stopping the engine
 Do not rev the engine immediately
before switching it off - stop the engine
when it is idling.
3 Regulating the boost pressure
 The system is optimized for fuel with an
octane rating of AON 90. The 2.3 T
(Aero) and 3.0t V6 are optimized for
NOTEIf the CHECK ENGINE warning light
starts to flash, ease off the accelerator
slightly. If the light does not cease to flash
within 5 seconds, stop the car in a suita-
ble place as soon as possible and turn off
the engine. The car must be towed to an
authorized Saab dealer.
If the CHECK ENGINE warning light
flashes, it indicates that the engine is
misfiring which can result in damage to
the catalytic converter.

152 Starting and driving
AON 93. One of the advantages of the
system is that it enables the engine to
be run safely on lower-grade fuel,
although not lower than AON 87.
 The maximum boost pressure is
adjusted automatically to the knocking
or pinging tendency of the engine.
Occasional, short-lived knocking when
the engine is under a heavy load is per-
fectly normal; the extent will depend on
the grade of fuel in the tank.
 Isolated instances of knocking are
more likely to occur with low-octane
fuel. This controlled form of knocking,
followed by a reduction in the boost
pressure, is a sign that the wastegate is
functioning and is perfectly safe for the
engine.
Important considerations with cata-
lytic 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 (mixture of
precious metals).
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. The fuel
and ignition systems are particularly
important in this context.
 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 an authorized Saab
dealer as soon as possible.
 If the engine fails to start (in very cold
weather or if the battery is flat), the car can
be jump started (manual gearbox only) or
started using jump leads to a donor bat-
NOTEIf constant knocking occurs every time a
load is put on the engine, this indicates a
malfunction in the system.
Have the car checked without delay by an
authorized Saab dealer.
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 be obtained at the corre-
sponding road speed.
NOTEUse only unleaded gasoline. Leaded gas-
oline is detrimental to the catalyst and
oxygen sensor and will seriously impair
the function of the catalytic converter.

tery. However, as soon as you have
started the engine, it is important that it
runs on all cylinders. If it is misfiring, allow
i t t o i d l e f o r u p t o f i v e m i n u t e s t o g i v e i t t i m e
to settle and run smoothly. If, after this
time, the engine still fails to run properly,
turn off the engine and get in touch with an
authorized Saab dealer for advice.  Never park the car on dry grass or other
combustible material. The catalytic con-
verter gets very hot and could therefore
start a fire.
 Never drive off if the engine is misfiring.
 If you jump start the car when the engine
is already up to normal temperature, the
engine must start to run on all cylinders.
Stop jump-starting if the engine fails to
start immediately.
Failure to follow these directions could
result in the catalytic converter and associ-
ated components being damaged, and
could represent a breach of the warranty
conditions.
3.0t V6: When starting the engine from cold
an electrical pump is activated. This pump
pumps air into the exhaust system so that
the catalytic converter will reach its normal
operating temperature more rapidly. The
pump is active for 30-60 seconds.
Fuel filler flapThe fuel filler flap is opened by means of a
button on the driver’s door. The flap is
spring-loaded, so it opens slightly automat-
ically when released.
NOTEIf the car runs out of fuel, it is possible for
air to get into the fuel system. If this
happens, the catalytic converter may
overheat and be damaged.
