What does auto mean on a car?

[McOwen]

The auto button on a car has different functions depending on its location in the vehicle. The AUTO button on the car air conditioning is used to distinguish between automatic air conditioning and manual mode; when the auto button for the windows is turned on, simply pressing the window open or close button will automatically open or close the window without the need to hold it manually; the auto button for the lights refers to the automatic headlights, which automatically turn the lighting system on or off based on the external light conditions. The light sensor sends the detected signal to the car's computer, and when the outdoor light dims, the headlights will automatically turn on, and vice versa; the auto button for the automatic parking is the automatic parking function.
