First, locate the air conditioning control area in the center of the dashboard in the FAW-Volkswagen Audi A4L. The knob on the right controls the air volume. The four buttons above the air conditioning control area in the FAW-Volkswagen Audi A4L control the direction of the air vents. The "A/C" button in the air conditioning control area of the FAW-Volkswagen Audi A4L is the air conditioning cooling switch.

I recently purchased a 2020 Audi A4L, and activating the external circulation mode is incredibly simple and convenient. After starting the vehicle, locate the button on the air conditioning control panel or the central display screen that has an arrow pointing outward. Press it lightly, and once the indicator light changes, it switches to external circulation mode. This mode directly draws fresh air from outside the vehicle, which is especially useful in urban areas where opening windows might let in dust or during rainy weather to prevent fogging. I often use the external circulation mode instead of opening windows during rush hour commutes—it keeps the air inside the car fresh and hassle-free while also reducing interior odors. It’s recommended to use this feature more often on routes with good air quality and to combine it with regular replacement of the cabin air filter to maintain system efficiency. Overall, the 2020 model’s design for this feature is very user-friendly, easy to learn, and highly practical.
