What does the AC switch mean?

[VanChristian]

The AC switch in a car's air conditioning system represents the switch for the vehicle's air conditioning compressor. Pressing the A/C switch will activate the air conditioning compressor. Below are specific introductions to common car buttons: 1. ON: On the car's light lever, there are ON and OFF options. ON means to turn on, and OFF means to turn off. 2. SEL key menu selection confirmation button: Generally found on the multifunction steering wheel. The OK key and SEL key have exactly the same function, but some cars use SEL while others use OK. 3. VOL+/-: Volume adjustment buttons. VOL is the abbreviation of the word volume, which can adjust the volume of the car's audio. 4. MUTE: Mute button, which can mute the sound with one press.
