Is It Necessary to Use the Recirculation Mode in Winter?

[Owen]

Decide whether to use the recirculation mode based on your specific situation. Below is relevant information about the recirculation mode: Functions of the recirculation mode: Blocks polluted air. When to use the recirculation mode: It can be used when the outside air is particularly polluted. The recirculation mode closes the airflow channels between the inside and outside of the vehicle. Without the fan on, there is no airflow circulation. When the fan is on, the airflow drawn in comes solely from inside the vehicle, creating an internal airflow cycle. The primary purpose of the recirculation mode is to promptly and effectively prevent external dust and harmful gases from entering the vehicle, such as when driving through areas with smoke, dust, unpleasant odors, or in heavy traffic, where it helps block harmful exhaust emissions from vehicles ahead. Another function is to maintain warmth inside the vehicle.
