Still, this feature isn’t meant to stay on all the time. In cold or rainy weather, trapped air can raise humidity and cause windows to fog. Long drives also benefit from fresh air, which helps maintain alertness and prevents the cabin from feeling stale.
The key is balance. Switch between recirculated and fresh air based on conditions, and replace your cabin air filter every 12,000 to 15,000 miles. Mastering this small button leads to clearer windows, cleaner air, and a more comfortable drive year-round.
