Controls in detail Climate control system Rear climate control Notes on climate control system The climate control system is operational whenever the engine is running. 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 and the current outside temperature. It can only function optimally when you are driving with the windows and the tilt/sliding sunroof closed. Nearly all dust particles, pollutants and odors are filtered out before outside air enters the passenger compartment through the air distribution system. 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. Keep the air intake grille in front of the windshield free of snow and debris. Do not obstruct air flow by placing objects on the air flow-through exhaust slots below the rear window. 1 Temperature control, left, raising 2 Display 3 Temperature control, right, raising 4 Temperature control, right, lowering 5 Temperature control, left, lowering 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. The air conditioning will not engage (no cooling) if the A/C mode (Y page 164) is deactivated. i If the vehicle interior is hot, ventilate the interior before driving off, see "Summer opening feature" (Y page 105). The climate control will then adjust the interior temperature to the set value much faster. Z 163
