The function that allows air recirculation in cars is not one of the best known to drivers. It’s a button that It is located next to the air conditioning which is shaped like a car and a series of arrows that will rotate inside. If enabled, indoor air is used to cool the interior, preventing contamination or harmful odors outside.
Some experts call it the “magic button,” because if used correctly, it is possible to save up to thirty percent of fuel while driving. The trick is to know when air recirculation is on and use it for as long as strictly necessary.

Yeah the air conditioning is activatedwill bring outside air into the cooling system and expel it inside. The same thing happens when the light is on, although it will take air from inside and recycle it back to a lower temperature.
This way it is possible to cool the car faster and more efficiently in certain situations. The outside like this the hottest air on the hottest days of the year and the vehicle has to make an extra effort to cool it.

It is recommended to use this type of function in traffic jams where there is trafficareas with dust, dirt or a lot of smoke in the environment.
Some drivers use this button by default when driving in big cities to keep outside pollution from entering. All of this ends up being a danger due to the deterioration of oxygen flow inside the car.
The ventilation system draws air from the interior and constantly expels it, so that it creates an overloaded environment, which can even cause dizziness in the worst case.
A significant saving
This magic button saves up to thirty percent fuel when using air or heat simultaneously.
When the outdoor temperature in summer is higher than the indoor temperature, recirculation allows fuel savings necessary to cool the air. The same thing happens in winter, when it is warmer in the cabin than outside.
