2002 SAAB 9-3 cabin filter

80 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.

84 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 74.
 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.
