What does 'auto' represent in a car?

[NadiaFitz]

auto literally translates to 'car' in English. In the context of button labels inside a car, it represents 'automatic'. Below are its functions: Functions: On the central air conditioning control panel, pressing this button activates the automatic air conditioning. The vehicle will automatically adjust the temperature of the air vents, air outlet mode, and wind speed based on the preset temperature and the detected temperature difference between the inside and outside of the car. The auto button for automatic headlights is located below the leftmost air vent on the dashboard. When the knob of the headlight control switch is turned to the auto position, the vehicle's small lights and low beams will be automatically controlled by the headlight computer. The vehicle uses the brightness level detected by the sunlight sensor to automatically turn on the lights.
