What does the auto button in a car mean?

[MacKimberly]

In a car, the auto button stands for automatic. When the auto button for the air conditioning is turned on, the car's air conditioning system will automatically adjust to a suitable temperature and fan speed. The auto button on the air conditioning system generally means automatic mode in the car's main control area. This button is usually used for the car's air conditioning, referring to the automatic air conditioning mode, as opposed to the manual mode. When the temperature inside the car is too high, activating the auto button will automatically adjust the air conditioning temperature and fan speed to lower it to a certain level, then maintain a constant fan speed. When the temperature rises again, it will automatically cool down. Conversely, when the temperature inside the car is too low, activating the auto button will cause the air conditioning to blow warm air to maintain a comfortable temperature, eliminating the need for manual adjustments.
