How to Use the Mercedes-Benz Air Conditioning Recirculation Mode?
2 Answers
In the external recirculation mode, the fan draws air from outside the vehicle into the cabin, meaning there is airflow between the exterior and interior. In the internal recirculation mode, the airflow passage between the inside and outside of the vehicle is closed. When the fan is turned on, the airflow drawn in forms a circulation within the vehicle's interior.
I've been driving a Mercedes for several years and find their air recirculation system quite convenient. There's usually a button on the center console with the recirculation icon - just press it to switch modes. The recirculation mode keeps the air circulating inside the cabin, which is particularly useful when outside pollution is high, like in traffic jams or industrial areas, significantly improving air quality. The fresh air mode brings in outside air, more suitable for long drives or highways as it helps prevent drowsiness. My routine is to use fresh air mode for the first few minutes after starting the car in the morning to ventilate, then switch to recirculation for cooling. Some Mercedes models also have settings on the screen to adjust fan speed and temperature linkage. In summary, flexibly switching between modes benefits health - don't overuse recirculation to avoid window fogging. Remember to check the cabin air filter during regular maintenance to ensure proper airflow and prevent future issues.
