Do I need to turn on AC when using the heater?

You don't need to turn on AC when using the heater. Because what you need in winter is warm air, which is hot air. Function of the heater: It generates heat by converting the heat from the coolant in the engine. For new energy vehicles, the heat is provided by a heating module. AC is the air conditioning cooling button. Pressing this button will start the air conditioning compressor. On some models, the indicator light on the button will illuminate, while others will display a prompt on the central control screen. Precautions for using the heater: During winter use of the air conditioning, since most vehicles now use automatic air conditioning, you may notice that the AC function is automatically activated after turning on the air conditioning. The reason for this is that when the driver sets the air outlet direction to the windshield, the defrosting function will be activated.
