The automatic mode maintains a constant temperature inside the Audi Q5 and dehumidifies the air. Air temperature, air delivery and air distribution are regulated automatically to reach the desired interior temperature as quickly as possible, and then to maintain this temperature. The system automatically compensates for any variations in the outside temperature and for the effect of direct sunlight.

The automatic temperature regulation only operates at temperature settings between +16°C and +28°C. If a temperature below +16°C is selected, low appears on the display of the sound system or the MMI^*. If a temperature above +28 °C is selected, the display will show high. In the two extreme settings the air conditioner operates continuously with maximum cooling or heating output, and the temperature is not regulated automatically.
