What does the AC MAX button in a vehicle mean?

[Jace]

The AC MAX button in a vehicle refers to the maximum air conditioning cooling setting. During summer when there is a significant temperature difference between the inside and outside of the car, it is not advisable to immediately set the air conditioning to a very low temperature upon entering. First, use high fan speed with natural air to disperse the hot air inside the cabin. Then, do not close all the windows completely. Turn on the air conditioning and allow your body to gradually adapt before adjusting the air conditioning to the desired temperature and closing the windows. This way, your body will not experience discomfort due to the sudden drop in external temperature. In southern winters, when using the air conditioning for heating, it is necessary to turn on the AC to utilize the compressor's cooling function to remove moisture from the air, reducing air humidity. Then, mix it with warm air to blow dry, hot air from the vents to prevent fogging on the car's interior glass.
