Audi's recirculation mode symbol features an arrow inside a car icon, while the fresh air mode symbol depicts a car with an arrow entering from outside the vehicle. Taking the 2020 Audi A6 as an example, this model belongs to the full-size luxury sedan category with body dimensions of: length 5038mm, width 1886mm, height 1475mm, wheelbase 3024mm, fuel tank capacity 73 liters, and curb weight 1800kg. The 2020 Audi A6 is equipped with a five-link independent suspension system both in the front and rear, powered by a 2.0L turbocharged engine delivering maximum power of 190PS (140kW) and peak torque of 320Nm, mated to a 7-speed dual-clutch transmission.

Regarding the recirculation and fresh air mode indicators in Audi vehicles, I've experienced them across various models multiple times. The recirculation symbol typically features a small circle at the center of the dashboard containing a car silhouette icon or an arrow rotating internally, indicating air is circulating solely within the cabin. When activated, this button closes external air intake - particularly useful in urban traffic to block exhaust fumes or pollen pollution. The fresh air mode symbol shows an arrow pointing from outside into the car interior, visually representing external ventilation which aids airflow and prevents window fogging. In Audi's automatic climate control systems, when combined with AUTO mode, it intelligently toggles between recirculation and fresh air to maintain optimal comfort. I recommend avoiding prolonged use of recirculation mode on highways to prevent CO₂ buildup that may cause drowsiness. Regular cabin air filter inspections are also crucial to prevent odors or reduced efficiency. Note these symbols are usually located on the center console control panel or near the steering wheel - clear identification contributes significantly to healthier driving.

Having driven an Audi for so many years, I'm very familiar with the air conditioning controls. The recirculation button is the one with the icon resembling a closed car interior - either a small car inside a circle or an inward-pointing arrow. Pressing it blocks outside air, which is useful for preventing moisture or dust when driving through tunnels or heavy rain. The fresh air button shows symmetrical arrows pointing from outside into the car, indicating outside air intake. I typically use this during clear weather or highway driving to quickly defog windows and maintain clear visibility. This works well with Audi's automatic function - when you press AUTO, the system intelligently determines when to switch modes. Remember not to use recirculation mode for extended periods, as it may cause window fogging or stale air. During maintenance, have the AC system and filters checked to prolong service life and ensure smooth operation of these controls. After all, safe driving comes first, and paying attention to these small details makes every drive more reassuring.

After buying the car, I realized the Audi air conditioning symbols are quite intuitive. The recirculation symbol is a circle with a car or an inward-pointing arrow inside, meaning it only circulates the air inside the car without letting it escape. The fresh air symbol shows an arrow coming from outside, as if saying fresh air is entering the cabin. Just find those small icons in the middle of the AC panel to use them easily—pressing the AUTO button will automatically switch between modes. In the city, it's better to use recirculation mode to block pollution, while switching to fresh air mode during outings for ventilation. If the AC doesn't respond right after starting the car, just check if the button is lit up.
