How to Turn Off the Car's Air Recirculation?

The reasons why the car's air recirculation cannot be turned off include damage to the recirculation switch or a malfunction in the car's air conditioning control circuit. Damage to the recirculation switch: It is necessary to check the vehicle's onboard computer or inspect the recirculation switch's fuse and carry out repairs. If the car's recirculation switch is manually adjusted, it might be due to the detachment of the hook behind the control panel. In this case, a mechanic should be consulted to remove the control panel and reattach the hook. Damage to the car's air conditioning control circuit: If the control circuit is damaged, the recirculation cannot be controlled via the switch, and the car should be taken to a service station for repair. How to activate recirculation: The air conditioning defaults to external air circulation. Pressing button "4" activates the air recirculation mode. Enabling air recirculation helps quickly lower the interior temperature and prevents outside air and odors from entering the car. The activation status is indicated by the LED light on the button. Pressing button "4" again turns off the recirculation mode.

I usually prefer to keep the air inside my car fresh, and turning off the recirculation mode is very simple. Just go to the center console and find the button with a small circle inside a car—most cars have it. Press it once, and the light will turn off, indicating that you've switched to the fresh air mode. This allows outside air to flow in, which is especially useful during rainy or foggy weather. It works wonders for defogging the windshield, clearing up the mist instantly and making driving safer. I also recommend using the fresh air mode more often when the air quality is good, such as on highways, to reduce inhaling exhaust fumes—health comes first. Additionally, remember to turn off the recirculation mode every one or two hours to prevent odors or blockages in the AC system. This helps maintain overall ventilation efficiency, and it's a quick and easy task you can do while driving.

As a family driver, I pay special attention to the air quality inside the car, and turning off the recirculation mode is my daily habit. It's not troublesome at all to operate—there's a small button near the steering wheel marked with a loop icon or the Chinese character for 'internal.' Just press it lightly, and the light goes off, indicating that the external circulation is now active. The benefit of doing this is that it introduces fresh air, reducing the risk of bacterial infections for my family, especially when taking the kids out, which gives me extra peace of mind. I often use this feature to defog the windows in winter or to clear out smoke odors in the car, making the driving experience much more comfortable. I recommend that beginners develop this habit; regularly turning off the recirculation mode can help maintain the system's lifespan and prevent mold issues. This simple little action significantly improves the in-car environment, making it feel particularly safe and reassuring.

During my recent test drive of a new model, I found it super convenient to turn off the air recirculation. Just enter the air conditioning menu on the central touchscreen and tap the recirculation option to deactivate it. After switching to fresh airflow, I immediately noticed the cabin air becoming fresher, while also preventing window fogging that could obstruct visibility. I enjoy exploring these features—real-world testing shows prolonged recirculation leads to stale air and elevated CO₂ levels, causing drowsiness. That's why I manually disable it while driving to let the system draw in fresh air. Modern vehicle designs prioritize user-friendliness with intuitive controls, making these healthy habits easy to maintain for daily comfort.
