How to Turn On the Interior and Exterior Circulation in a Passat?

Below the center console, there is an 'A' button. Pressing it to light up indicates interior circulation, while not lighting up indicates exterior circulation. Press the button to turn the air recirculation mode on or off. If the indicator light on this button is illuminated, it means the mode is activated.
I've been driving a Passat as my daily commuter, and the air recirculation operation is very intuitive. After starting the engine, there's an air conditioning control panel on the center console. Look for the button with the icon—the recirculation mode usually shows two small arrows inside a circle. Press it, and when the indicator light turns on, the recirculation mode is activated. This mode only circulates the air inside the car, which is especially useful in heavy traffic or polluted urban roads to prevent inhaling external dust. The external circulation button is usually placed next to it, with an icon of an arrow pointing into the car. Pressing it switches to external circulation, drawing in fresh air, which is great for ventilation during high-speed driving to prevent stuffiness. The system comes with an AUTO function that automatically switches modes, but manual control responds faster. I recommend adjusting the temperature knob for comfort—for example, using recirculation in summer improves cooling efficiency. The Passat's design is simple and easy to use, making operation effortless.
When traveling with my family in the Passat, I often adjust the air recirculation. After starting the vehicle, there's a dedicated air recirculation button on the climate control panel near the steering wheel. The recirculation button icon looks like two arrows inside a circle. Pressing it closes the external air intake, which is suitable for hazy days or when children are sitting in the back seat, helping to reduce odors and allergens. The fresh air button allows outside air to enter, making driving on highways or in rural areas more refreshing. Operation is simple: the corresponding mode is activated when the button light is on. In automatic mode, it switches intelligently, but manual adjustment is more direct. I also like to combine it with the fan speed button to control airflow, making the cabin air more circulated. The Passat's interface layout is clear and easy to learn.
