2005 Saab 9-3 Owner's Manual - Page 113

Instruments and controls Functions Pressing 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. 111 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. See also Profiler on page 117. Temperature, air distribution, fan speed and recirculation 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 settings are programmed under Profiler (see page 117).
