How to Turn on the External Air Circulation in a Car?

[VanMatteo]

To turn on the external air circulation in a car, simply press the external circulation button on the center console. The button is marked with an arrow pointing from the outside of the front windshield into the car. The external circulation mode uses a fan to draw outside air into the car. The air blown by the fan comes from outside the vehicle, and even when the fan is off, airflow is still drawn into the car while driving, replenishing the interior with fresh air. The car air conditioning system is an air conditioning device installed in the vehicle, capable of cooling, heating, ventilating, and purifying the air inside the cabin. It provides a comfortable environment for passengers, reduces driver fatigue, and enhances driving safety.
