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. The air conditioning will not engage (no cooling) if the A/C mode (Y page 179) is deactivated. G Warning! Follow the recommended settings for heating and cooling given on the following pages. Otherwise the windows could fog up, impairing visibility and endangering you and others. X Keep the air intake grille in front of the windshield free of snow and debris. G Warning! Severe conditions (e.g. strong air pollution) may require replacement of the filter before its scheduled replacement interval. A clogged filter will reduce the air volume to the interior and the windows could fog up, impairing visibility and endangering you and others. Have a clogged filter replaced as soon as possible at an authorized Mercedes-Benz Center. 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.
