2004 SAAB 9-3 Owners Manual

105 Instruments and controls
The system uses four sensors:
 Outside air temperature sensor
 Cabin air temperature sensor
 Sun sensor
 Blended air temperature sensors (located
in the heater unit and the outer panel vent
duct).
The sun sensor is located centrally on the
top of the fascia.
Note:
If the sun sensor is covered, the ACC
system will not be able to regulate the cabin
climate as intended, especially in strong
sunshine.Condensation waterWhen 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.

106 Instruments and controlsFunctionsPressing AUTO will cancel all manual settings.
If a manual function is selected, it will be locked in but other functions
will be controlled automatically.
The selected temperature is always maintained automatically.
Temperature, air distribution, fan speed and recir-
culation will be controlled automatically.
In falling temperatures the A/C compressor is
switched off at approx. 32°F (0 °C).
In rising temperatures the A/C compressor is
switched on at approx. 40°F (+5 °C).
If, when starting the car, the outside air temperature
is between 32°F and 40°F (0 and +5 °C), the A/C
compressor is switched on.
Pressing AUTO once will cancel all previous manual
air distribution selections.
When the engine is started, the ACC system will be
in AUTO mode, provided that no air distribution set-
tings are programmed under Profiler (see page
112).
The A/C compressor must be turned on and off
manually with the AC button.
The compressor can only be turned on or off while
the engine is running.
This function has two modes:
 AC – The system cools and dehumidifies the
incoming air. This symbol is not shown in the
display.
 AC-OFF – The A/C compressor is switched off.
The incoming air is not cooled or dehumidified.

To turn the system OFF, press and hold (or press
repeatedly) the button to reduce the fan speed until
the fan is switched off. Then release the button and
press it once more.
The A/C compressor will now be disengaged. To re-
engage the A/C, press one of the following buttons:

The A/C compressor will be
switched on if it was previously
engaged, and the air distribution
and fan speed will switch to AUTO. Higher fan speed The A/C compressor will be
switched on if it was previously
engaged, the air distribution will return to its previ-
ous setting and fan speed will increase. Defroster The A/C compressor will be
switched on if it was previously
disengaged, the air distribution will switch to
Defroster and the fan speed will increase (6 bars
on the display out of a maximum of 8).
When the system is switched OFF:
 The fan and A/C compressor are switched off.
 The temperature control is set to 0 % heat.
 The current air distribution setting is retained.
 Recirculation can be selected.
The rear window and door mirror heating can be
controlled manually or automatically (refer to
Profiler).
Switch off the rear window and door mirror heating
as soon as the glass is clear. The heating will be
turned off automatically after 12 minutes.
Refrain from placing sharp objects on the parcel
shelf, to avoid damaging the heating element.

Formation of ice and mist in extreme weather conditionsIt is only in the most extreme conditions that icing and misting of
window glass are likely to be a problem, such as in torrential rain or
severe cold coupled with high relative humidity, or when passengers
are perspiring heavily or wearing wet clothes. The following mea-
sures are recommended if such problems should occur:
1 Select and set the temperature to 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.

tomizations can be made at a Saab dealer.Tips(before contacting a Saab workshop)
 If you feel that the ACC system is not func-
tioning satisfactorily, select "Default
Settings" under Profiler (see page 112.
 To prevent the smell of washer fluid from
entering the car, recirculation can be acti-
vated automatically while the windshield
is washed. The recirculation symbol will
however not light up. This function is
optional; contact a Saab dealer. This
automatic recirculation is the factory
default setting as long as the system is
working in full "AUTO" model with no
customized settings.
