Do You Need to Press AC When Turning on the Car Heater?

You don't need to press AC when turning on the car heater. AC is for activating the air conditioning compressor, meaning that only when this button is pressed will the compressor work, and the air blown out by the blower will be cold. If you turn on the heater and also press AC, it will increase the vehicle's fuel consumption. AUTO is a unique function of automatic car air conditioning, which automatically selects between cold and hot air based on the set interior temperature. However, the AC button exists independently and won't automatically activate when cooling isn't needed. The purpose is to keep the compressor from working when cooling is unnecessary to save fuel.
