What is the actual purpose of the air recirculation button in your car?

When should this function be disabled?

Although recycling mode has several advantages, it should not be used continuously.

In cold or humid weather, it is best to switch back to outside air mode.

For what ?

Because air recirculation can promote the accumulation of humidity in the passenger compartment.

This humidity can quickly cause fogging on the windows, reducing visibility and increasing risks while driving.

The passage to outside air then allows:

• to remove moisture;
• to limit the formation of fog;
• to improve visibility.

It is therefore important to adapt the use of this button according to the weather conditions and driving situation.
