Does the Light Indicate the Activation of Internal Circulation?

[DiMariana]

The illuminated light indicates internal circulation, while the light off indicates external circulation. Internal circulation means the airflow channel between the inside and outside of the vehicle is closed, preventing outside air from entering the car and only circulating the air inside the vehicle. Precautions for using the car's internal circulation: For the first 6 months of a new car, it is essential to enhance ventilation, regularly clean the car's air conditioning, and strive to maintain fresh air inside the car. Special attention should be paid to avoiding the use of perfumes or air fresheners to mask unusual odors inside the car. The car air conditioning is an air conditioning device installed in the vehicle, and its functions include: 1. Cooling, heating, ventilating, and purifying the air inside the cabin; 2. Providing a comfortable riding environment for passengers; 3. Reducing the driver's fatigue and improving driving safety.
