Automatic operation ensures constant temperatures in the interior and dehumidifies the air inside the vehicle . Air temperature, volume
and distribution are controlled automatically to reach or maintain
the desired interior temperature as quickly as possib le. Fluctuations
in exter ior temperature and the effects of temperature from the
position of the sun are compensated for automatica lly.
This operating mode works only in the adjustable temperature range, from 60 °F ( + 16 °C) to 84 °F ( +28 °C). If a temperature below
60 °F (+16 °C) is se lected,
