How to turn on the air conditioning in a car?

[EliLee]

To turn on the air conditioning in a car, adjust the knob to the blue area. Generally, blue represents cold air in car air conditioning systems; red represents warm air; and the middle position indicates a moderate temperature. If you want to turn on the heater, adjust the knob to the red area and press the AC switch. The middle knob controls the fan speed, while the right knob adjusts the airflow direction, allowing you to direct air to the feet, hands, or windshield only. The car air conditioning system, abbreviated as car AC, is used to regulate and control the temperature, humidity, air cleanliness, and airflow inside the car cabin to a comfortable state. It provides a pleasant environment for passengers, reducing travel fatigue, and creates good working conditions for the driver, playing a crucial role in ensuring safe driving as a ventilation device.
