In all cars, even those without air conditioning, there is a button in the car cabin that allows the vehicle to heat up more quickly. This is a feature that often comes in handy when driving a car in cold weather.
The button or slider to activate the recirculation circuit is usually next to the airflow knob in the car. Like some secret buttons, we don’t always know what it’s for. This feature is very useful, especially at this time of year. When activated, special flaps in the ventilation ducts close to limit the flow of outside air into the car. The fan then uses the air present in the car and, depending on the selected temperature, can heat or cool it. Thus, the outside air does not mix with the air that circulates inside the vehicle.
It is recommended to use the closed circuit when a car smokes in front of you or when you are stuck in a traffic jam, for example. It also prevents bad exterior odors from entering the car. In autumn and winter, the closed circuit is especially useful for quickly warming up the car on frosty mornings. However, it must be remembered that the recirculator should only be used for a limited period.

Closed circuit, what are its limits?
Switching to open circuit mode prevents windows from fogging up or water droplets from collecting. Driving in recirculation mode and a lack of fresh air can cause a buildup of moisture exhaled by passengers. In addition to making the windows fog up, it will make the atmosphere inside the car stifling.

Set the temperature to about 19 degrees.
