Should the AC be turned on when the car air conditioner is in AUTO mode?

AUTO switch and AC switch can be turned on simultaneously. 1. In summer, when the AUTO button is pressed, the AC button will automatically activate. 2. In winter, after the engine warms up, it uses the water circulation system in the engine to deliver heat, so the AC switch does not need to be pressed for heating. The following explains the function of the AC button: 1. To blow cold air in summer, the AC must be turned on to activate the compressor for cooling, thereby reducing the temperature inside the car. 2. For warm air in winter, the car air conditioner's heating does not rely on the compressor but instead uses the engine's water temperature as the heat source.
As a seasoned driver with over a decade of experience, I often use the automatic air conditioning mode and found that there's no need to manually press the AC button. The system automatically turns the cooling on or off based on the set temperature. For example, it activates the AC to cool down when the car is hot in summer, and may turn it off to just blow air in winter or when it's not too hot. This approach saves fuel and is convenient. Manual intervention can disrupt the automatic logic, wasting battery and compressor power. It's best to let it run automatically unless the windshield fogs up, then manually turn on the AC for dehumidification. Don't worry too much about minor details while driving; focus on safe driving instead. Regularly checking the air filter is also important, as accumulated dust can affect automatic functions. I recommend getting into the AUTO habit—it saves energy and extends component lifespan, especially in traffic jams where you don't need to fiddle with buttons, making it truly effortless.
As an automotive technology enthusiast, I have a deep understanding of automatic air conditioning logic. In AUTO mode, the computer continuously monitors interior and exterior temperature and humidity to automatically determine whether to activate the AC compressor. For example, when set to 22°C, if the cabin temperature is high, the system will turn on the AC for cooling; if the ambient temperature is mild, it may only ventilate without activating the AC. You don't need to manually operate the AC button at all, as that would interfere with the intelligent algorithm. Additional activation actually increases fuel consumption because the engine bears a heavier load when the compressor is running. For optimization, it's recommended to maintain system cleanliness and regularly replace the air filter near sensors to ensure accurate data readings. This automated design is originally intended to enhance comfort and efficiency, with manual intervention only necessary in extreme situations, such as pressing the AC button for rapid defogging during heavy rain.
