Recirculating air when entering a tunnel

To prevent the inflow of polluted air into the vehicle when passing through a tunnel, this function automatically closes the windows and switches the climate control system to recirculated air position for about 7 seconds before entering a tunnel based on the map information of the navigation and the speed of the vehicle.

The windows automatically close before entering a tunnel and area requiring air recirculation. The windows open to the previous position after passing through the area. If the power window switch is operated before the window opens, the window does not open to the previous position.

To use this feature, it can be enabled from the Settings menu in the infotainment system. Select:

• Setup > Vehicle > Climate > Recirculate air > When entering tunnels

Operating conditions

One or more of the windows are open or outside (fresh) air position is selected.

• The activation time for the function may differ depending on the gap between the GPS data and vehicle speed.

• The function activates until you have passed through continuous tunnels.

• When entering a tunnel, recirculated air position may cause fogging of the windscreen. Press the windscreen defroster button.

• The function does not operate in short tunnels.

• The function may not activate if the GPS is not working properly.
