As we prepare for a winter storm across the area, there's one button people may not know how to use in these temperatures.

That button has an arrow turning around inside of the car. It's called the recirculation button.

In the winter, World Class Auto Service says to avoid using it because it traps humidity inside the car, which can result in the foggy windows you see in the winter. It plays more of an important role in the heat.

"It recirculates the kind-of-cool air that you get from the A/C when you first turn it on," the website said. "The longer it's on, the cooler your car gets until it's as cool as it can possibly be."
