76 Instruments and controlsManual climate-control
systemThe air is drawn in through an intake at the
bottom edge of the windshield. It passes
through an efficient filter before being
routed through the climate-control system
and into the cabin. The cabin discharge vent
is located on the right behind the rear
bumper. The air discharge vents should be
kept free of snow and ice in the winter.
The rate of air flow inside the car is con-
trolled by means of the fan switch. Temperature control The temperature of the incoming air can
be steplessly varied using the temperature
control.
Air distribution The air distribution control is used to direct
the flow of air to the defroster, dash and floor
vents.
The control permits settings intermediately
between the three main settings so that the
available air can be apportioned between
the floor and the windshield (defroster) or
between the floor and the panel.
To counter cold drafts from the front side
windows when the control has been set to
defroster or floor, a small flow of air issues
from the dash vents. The dash vents swivel universally, so that
the air can be directed as desired.
The flow of air through the dash vents can
be adjusted for each vent by means of the
adjacent control.
Air to the rear side windows is supplied by
the floor ducts. To demist these windows
you should therefore select a defroster/floor
combination.
If the windows are thoroughly cleaned it is
much easier to keep them free of mist.

The air conditioning is combined with the
conventional climate-control system and is
switched on by pressing the button,
provided that the fan control is in
position 1-4.
The incoming air is treated in three stages:
first it passes through a filter; it is then dehu-
midified and cooled and, finally, if required,
heated.
The air conditioning can be used at outdoor
temperatures down to 32°F (0°C). Condensation water When the A/C compressor is on, the incom-
ing air is dehumidified. The resulting con-
densation water is drained away through an
outlet under the car.
It is therefore perfectly normal for water to
be seen dripping from this outlet when the
car is parked. The warmer the ambient air
and the higher the humidity, the more con-
densation will form. When the button is depressed the
regular air intake will be closed. In this posi-
tion, the air inside the cabin is recirculated.
Use recirculation when you want rapid cool-
ing, at extremely high air temperatures.
Switch the air conditioning (A/C) on first.
Recirculation can be useful to activate man-
ually to prevent unpleasant smells being
drawn into the car from outside.
Note that recirculation should not be
used when the outside temperature is
lower than 50°F (+10°C) except briefly,
e.g. to avoid unpleasant air from enter-
ing the car. Prolonged use of recircula-
tion could cause the windows to mist or
ice up.

The button is located on the climate-control
panel. An LED in the button is lit as long as
heating is on.
Switch off the heating as soon as the rear
window is clear. It will go off automatically
after about 10 minutes.
If the battery voltage is lower than 12 V the
heating will be switched off earlier so that
the battery can get the benefit of the alterna-
tor charge.
Avoid placing sharp objects on the rear
parcel shelf; the heater elements may suffer
damage if such objects touch the rear win-
dow. Do not switch the heating on until you
have started the engine.
Recommended settings in
severe cold On starting with a cold engine, set the fan
switch to position 2 and select defrost to
heat the cabin and defrost the windshield as
quickly as possible.
When the engine is warm enough for the
reading of the temperature gauge to start
rising, fan setting 3 may be chosen. Once
the windshield is clear, the air-distribution
control should be shifted two steps to the
left.
The warm-up time of the engine depends on
the kind of driving. Town driving in high gear
with a low RPM gives a longer warm-up time
than highway driving with a higher RPM.
Do not use position 4 on the fan switch, as
this is mainly intended to provide rapid cool-
ing in hot weather.

80 Instruments and controlsAutomatic climate
control (ACC)The air is drawn in through an intake at the
bottom edge of the windshield. It passes
through an efficient filter before being
routed through the climate-control system
and into the cabin. The cabin discharge vent
is located on the right behind the rear
bumper. The air discharge vents should be
kept free of snow and ice in the winter.
ACC (Automatic Climate Control) automati-
cally maintains the desired cabin tempera-
ture, regardless of the weather outside.
The system will achieve the desired temper-
ature in the quickest possible way.
Note that heating or cooling is not
speeded up by setting the temperature
higher or lower than you really want.
For the ACC system to be most effective, all
windows, and the sunroof if there is one,
must be closed, and the panel vents must
be open.
The incoming air is treated in three stages:
first it passes through a filter; it is then dehu-
midified and cooled and, finally, if required,
heated. The temperature interval within which you
can make adjustments is 58-82°F
(15-27°C). Outside it, there is the HI position
(max. heat and high fan speed) and the LO
position (max. cooling and max. fan speed).
The displayed temperature is not the actual
temperature but corresponds to the comfort
level normally experienced at that tempera-
ture after allowance has been made for the
air flow, relative humidity, solar radiation,
etc., currently prevailing inside the car.
 The most usual temperature setting is
66-74°F (19-23°C), depending on per-
sonal preference and what clothing is
worn.  It is recommended that changes in the
temperature setting be made in steps of
2°F (1°C).
 Conversion between °C and °F is done in
the SID unit; see ”Units and language ver-
sions”, page 69.
 During the cooling phase in warm
weather the panel vents must be open.
 Do not manually select recirculation in
cold/wintery weather. The reduced air
flow can cause misting and ice on the
inside of the windows.

Starting in cold weather: The automatic
climate control system selects the defroster
position, max. heating and low fan speed to
begin with.
As the engine temperature rises, the fan
speed is increased and air is routed towards
the floor.
As the temperature inside the car nears the
selected value, both the fan speed and the
heat will be decreased to a level determined
by the system.
Starting in hot weather: The automatic cli-
mate control system selects air to the panel
vents and high fan speed. Recirculation is
switched on about 30 seconds after starting
if the selected cabin temperature is mark-
edly lower than the actual temperature.
Unless the ECON button has been
depressed, the A/C compressor is always
switched on at outside temperatures above
32°F (0°C) in order to cool and dehumidify
the incoming air, unless the ECON button
has been depressed.
As the temperature inside the car nears the
selected value, the fan speed will be
decreased to a value determined by the
system.
Action to be taken in special types of
weather Normally, misting and icing problems on the
windows do not occur other than in extreme
situations, e.g. when you are driving in
heavy rain or severe cold in combination
with high air humidity or when those travel-
ling in the car are sweaty and wet. If you
have trouble with misting or icing in such
cases we suggest the following counter-
measures:
1 Select and temperature 70°F
(21°C).
2 Select . If this is not enough ...
3 Increase the fan speed. If this is not
enough ...
4 Select a higher temperature.
Air to the rear side windows is supplied by
the floor ducts. To demist these windows
you should therefore select a defroster/floor
combination by pressing both buttons at the
same time.

136 Starting and drivingUseful tips on cold climate startingIf 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.
Every time the engine is switched off the
spark plugs are automatically cleaned. If
your attempt to start nevertheless fails, let
go of the ignition key and allow it to spring
back. This initiates more vigorous cleaning
of the sparking plugs which goes on for
about 5 seconds. Then start in the ordinary
way. Do not touch the accelerator; if the
accelerator is pressed to the floor the fuel
supply is shut off.
Important
considerations for
drivingThe engine-management system in the
Saab 9-3 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 drive-
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 is in the mid-range on tempera-
ture gauge) to avoid unnecessary
wear. If the needle of the pressure
gauge repeatedly enters the red zone
the engine may suddenly lose power,
owing to the intervention of a monitor-
ing system which curtails the charging
pressure. Get in touch with an autho-
rized Saab dealer at once.
 A safety function prevents the engine
from revving faster than 6,200 rpm by
temporarily shutting of the fuel injec-
tors.2 Stopping the engine
 Do not rev the engine immediately
before switching it off - stop the engine
when it is idling.
3 Regulating the charging pressure
 The system is optimized for fuel with an
octane rating of AON 90. For cars with
205 hp engines and the Viggen, the
system is optimized for 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. However, engine perfor-
mance will fall off slightly, and heavy
loading should be avoided. For best
performance you should use the rec-
ommended grade of fuel, AON 90
(205 hp engine and Viggen AON 93).
 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.
