Do I need to turn on the AC when using the air conditioner in summer?

In summer, you need to turn on the AC when using the air conditioner. The AC button is the cooling switch of the car air conditioner, and the compressor can only cool after it is turned on. In hot summer, when you turn on the AC button, you need to adjust the temperature to the blue position. For automatic air conditioners, you can set a temperature and then press the AUTO button, and the automatic air conditioner will adjust the interior temperature automatically. The car air conditioner refers to the air conditioning device installed in the car, which can cool, heat, ventilate and purify the air in the compartment, providing a comfortable riding environment for passengers, reducing the driver's fatigue and improving driving safety.
