However, air recirculation should not be used all the time. In cold or rainy conditions, trapping air inside the cabin can increase humidity and cause the windows to fog up. Switching back to fresh air helps keep the windshield clear and visibility safe. On long drives, allowing fresh air into the cabin can also reduce fatigue by maintaining healthier oxygen levels. To keep the system functioning properly, remember to replace your cabin air filter regularly—typically every 12,000 to 15,000 miles. Understanding how and when to use this small button can lead to a safer, more comfortable ride in any season.
