A Neglected Button on Your Car Can Help Save Gas

The function of your vehicle’s “air recirculation button”

(KODE) – It’s a button that almost everyone has at least glanced at on their vehicle’s climate control dashboard, but do you know its purpose?

The “air recirculation button” has two functions; mainly dealing with the vehicle’s air conditioning system.

On most cars, trucks, and SUVs, the recirculation air button is easily identifiable, with its symbol depicting a semicircle inside the outline of a vehicle.

Many people say they know the button, but don’t know when it should be on or off.

The air conditioning features on the center dash of a 2018 Ford Escape include the air recirculation button.

According to Tabitha Ruhl, director of Joplin Transmission and Auto Center, pressing that single button on your vehicle’s dashboard climate control will cut outside air to the car’s interior, thereby “recirculating” air inside. inside your vehicle.

This ensures that you are recirculating conditioned air rather than hot air from outside.

Now that summer is right around the corner, Ruhl says the recirculation air button is great for turning up your air conditioning to help your vehicle’s cabin get as cool as possible, quickly.

Another function of this air conditioning system is to prevent pollution and exhaust gases from entering the vehicle.

Activating this button will also help significantly reduce pollen while driving, which is a great benefit if you suffer from outdoor allergens.

In the video below, Ruhl summarizes your vehicle’s recirculation air button, including how using it could save you money on gas.

“The button works by helping your car recirculate cool air from your air conditioner from the moment you turn it on. If you choose not to use the button, your car will have to draw in air from outside and work twice as hard to cool that air as the already cooled air around you,” Ruhl said.

Since the recirculation air button goes hand in hand with a vehicle’s air conditioning system, you’ll probably want to use it when the outside temperature is above 75 degrees (Fahrenheit).

“If you don’t turn on the air recirculation button, your car’s air conditioning will constantly cool the hot air from outside your vehicle and have to work much harder, putting more strain on the fan and compressor. of air,” Ruhl said. .

Another benefit of using the recirculated air feature is the money you could save on gas.

“Cars are generally more fuel efficient when the air conditioner is set to recirculate interior air. This is because maintaining the same cool air requires less energy than constantly cooling hot air from outside,” Ruhl said.

While the recirculation button is great for the summer months, it may be best avoided in the winter or when your windows fog up.

“Whenever you use defrost, it’s best not to activate this button. Also, using it while your heater is on won’t do anything to your vehicle,” Ruhl said.
