Recirculating air when entering a tunnel

To prevent the inflow of polluted air into the vehicle when passing through a tunnel, the climate control system is operated using the navigation map information and vehicle speed as follows:

To use this feature, it can be enabled from the infotainment system. Select: Settings > Vehicle > Climate > Internal air circulation

  • Tunnel section : The climate control system switches to recirculation mode for about 7 seconds before entering a tunnel.

Operating conditions

  • The climate control system’s fresh mode is selected.

  • The activation time for the feature may differ because of the time gap between the GPS and vehicle speed.

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

  • When entering a tunnel, recirculation mode may cause fogging of the windscreen. Use the front windscreen defroster button.

  • The feature does not operate in short tunnels.

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

  • The infotainment system may change after software updates. For more information, refer to the user’s manual provided in the infotainment system and the quick reference guide.
