Most drivers have seen the small dashboard icon showing a car with a circular arrow inside it.
Few, however, truly understand its impact.
That simple button controls your vehicle’s air recirculation system — and when used correctly, it can dramatically improve comfort, air quality, and even fuel efficiency inside your car.
