It's best to turn on the air conditioner for automatic cooling in hot weather, because it automatically feels too hot.
When the weather is hot and it is necessary to turn on the air conditioner to cool down, press the AC button, and there should be an indicator light on the button. The automobile air conditioner refrigeration compressor starts to work, and the air outlet blows cold air to reduce the temperature inside the car.
When you need refrigeration, press the AC key, and at the same time, you need to turn the temperature selection switch to the blue part and turn on the fan switch, so that cold air will be blown out. If it is an automatic air conditioner, you can press the auto key at the same time, and the automatic air conditioner will automatically adjust the temperature inside the car.
When you need to warm up in winter, turn the temperature selector switch to the red part, turn on the fan switch, and warm air will be blown out without pressing the AC key.
