You’ve probably noticed a button on your car’s dashboard that you’re not entirely sure about—it’s the one with an icon of a car and a circular arrow inside. Ring a bell? That’s the air recirculation button. It may seem minor, but it plays a big role in your driving comfort—and potentially your safety. However, using it incorrectly can have unintended side effects. Here’s what you need to know.
What Is the Air Recirculation Button For?
Simply put, this button blocks outside air from entering the cabin and recirculates the air already inside your vehicle. It creates a closed-loop system that works with your car’s ventilation to heat or cool the interior based on your settings, then redistributes that air through the vents.
While this feature is straightforward, it’s important to use it wisely.
