How to Turn on the BMW X3's External Air Circulation?
1 Answers
To adjust the internal and external air circulation, simply ensure the light is off for external circulation. Here is an introduction to the car's external air circulation: 1. The button for adjusting external and internal air circulation on a BMW is slightly different from other cars. The button has the letters A and M. 2. A stands for automatic switching between internal and external circulation (meaning the car checks and adjusts the circulation automatically). M is for forced internal circulation. If no light is on, it means external circulation is active. Each press of the button will usually display the corresponding status on the screen. 3. External circulation means the air duct between the outside and inside of the car is open. The fan draws air from outside, and even if the fan is off, airflow is still drawn into the car while driving, replenishing fresh air inside. 4. Internal circulation closes the airflow channel between the inside and outside of the car. If the fan is off, there is no airflow circulation. When the fan is on, the airflow drawn in comes only from inside the car, creating internal airflow circulation. During long drives, it is advisable to periodically switch to external circulation to ensure fresh and smooth airflow inside the car.
