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.

As an experienced driver with years behind the wheel, the 2020 Audi A4L's external circulation activation is very intuitive. After starting the car, simply press the physical button marked with the internal/external circulation symbol in the climate control panel - when the light turns off, it indicates external circulation is engaged. This draws in outside air, effectively preventing window fogging or CO₂ buildup inside the cabin, especially useful during long-distance driving for safety and convenience. I frequently use this feature on highways for fuel-efficient ventilation, avoiding the stuffiness caused by internal circulation. Just remember to switch back to internal circulation in heavily polluted areas for health protection - the operation takes mere seconds with no complicated settings required, making it extremely straightforward.

On the 2020 Audi A4L, activating the exterior air circulation is primarily achieved by pressing the recirculation button on the climate control panel—a single press switches from interior to exterior mode. The exterior circulation mode allows outside air to flow into the system, aiding in dehumidification and odor removal, thereby enhancing driving comfort. From an air conditioning principle perspective, it improves ventilation efficiency, preventing stuffiness caused by the repeated circulation of interior air. For optimal results, use it in environments with fresh air—quick, simple, and responsive.

In daily use, the 2020 Audi A4L's external circulation operation is incredibly convenient. Just start the engine, locate the circulation button in the air conditioning panel, and press it once to turn off the light. The external circulation draws in fresh air, ensuring kids in the back seat don't complain about stuffiness, and prevents window fogging on rainy days for added safety. I often use it during morning and evening commutes instead of opening windows to avoid insects or exhaust fumes. It's recommended to pair it with the car's air purification function for optimal comfort for the whole family.

To activate the 2020 Audi A4L's external air circulation, simply press the circulation button once, and the light turning off indicates success. I recommend using it frequently in good weather for ventilation, reducing humidity and odors inside the car. External circulation helps prevent window fogging, enhancing visibility and safety. Long-term disuse can lead to dust accumulation in the air filter, so regular cleaning is advised to maintain efficiency. The operation is instant, simple, and highly effective.
