You can operate the climate control system in either the automatic or manual mode. The system cools or heats the interior depending on the selected interior temperature. It can only function optimally when you are driving with the windows and the tilt/sliding panel closed. Nearly all dust particles, pollutants and odors are filtered out before outside air enters the passenger compartment through the air distribution system. X Keep the air intake grille in front of the windshield free of snow and debris. i If the vehicle interior is hot, ventilate the interior before driving off, see "Summer opening feature" (Y page 97). The climate control will then adjust the interior temperature to the set value much faster. Deactivating the climate control system G Warning! When the climate control system is deactivated, the outside air supply and circulation are also deactivated. Only choose this setting for a short time. Otherwise the windows could fog up, impairing visibility and endangering you and others. X G Warning! Severe conditions (e.g. strong air pollution) may require replacement of the filter before its scheduled replacement interval.
