What are the symbols for car air conditioning recirculation and fresh air mode?

[Santos]

Air recirculation symbol: A car icon with an arrow circulating inside the vehicle. Fresh air mode symbol: A car icon with an arrow pointing from outside into the vehicle. Below are relevant explanations about air recirculation and fresh air mode: 1. Fresh air mode: When activated, it allows outside air to enter the vehicle as cooled or heated air, typically used when outdoor air quality is good. 2. Recirculation mode: When activated, it circulates and cools/heats the existing air inside the vehicle without drawing in outside air, generally used when outdoor air quality is poor.

The symbols for recirculation and fresh air modes are easily identifiable on the air conditioning control panel. The recirculation symbol typically features a car icon with an arrow circling inside, indicating that the cabin air is being recirculated without drawing in outside air. The fresh air mode symbol shows an arrow pointing into the car icon from outside, representing the intake of fresh air. When driving, I find recirculation particularly useful in heavy traffic or areas with severe air pollution, as it reduces exposure to exhaust fumes and pollen, maintaining a clean and comfortable cabin environment. Fresh air mode, on the other hand, is ideal for highway driving or when first entering the vehicle, as it promotes air circulation, quickly removes humidity and fog—especially helpful during rainy days or winter when windows tend to fog up. The location of these buttons varies by car model; some are positioned near the steering wheel in the center console area, while others are virtual buttons on touchscreens. On long highway drives, I periodically switch between modes to prevent carbon dioxide buildup from prolonged recirculation, which can cause dizziness.

The symbol for the car's air recirculation mode is a small circular arrow inside the car, clearly indicating air circulating internally; the fresh air mode symbol features an arrow pointing from outside into the car. I usually switch to recirculation mode in city traffic to reduce exposure to polluted air and protect my health; on highways, I change to fresh air mode to let in fresh air, feeling refreshed. Some new cars even have an automatic mode that intelligently switches between the two, making it hassle-free. Using recirculation mode in summer cools the car faster and saves fuel, while fresh air mode in winter helps defog the windows. Operation is simple—just press the button, typically located in the middle or right side of the climate control panel. Avoid using only one mode for extended periods; alternating between them keeps the cabin air fresher. Regularly cleaning the air filter is also important, otherwise, pressing the button won’t be effective.

The recirculation icon features a car interior with a rotating arrow, indicating air is only circulating inside the vehicle; the fresh air icon shows an external arrow pointing into the car, representing the intake of outside air. In daily driving, recirculation is used to reduce inhalation of external pollutants, while fresh air mode promotes ventilation and defogging. It is recommended to use recirculation in tunnels or industrial areas, and switch to fresh air mode on highways or in suburban areas. The button is conveniently positioned for easy operation.
