What does the AUTO light switch in a car indicate?

[OKyle]

"AUTO" stands for automatic air conditioning. When this function is activated, the system will automatically adjust and control the temperature and airflow of the air conditioning based on information obtained from sensors inside and outside the vehicle, maintaining a comfortable temperature inside the car and eliminating the need for manual adjustments. Here is a brief introduction about the AC part of the air conditioning: 1. AC: stands for air-conditioning, meaning air regulation. 2. The difference between using AC and not using AC: one utilizes the air conditioning compressor, while the other does not. Simply put, use AC for cooling in summer and turn off AC to utilize the radiator temperature for heating in winter.
