Controls in detail Automatic climate control* The automatic climate control is operational whenever the engine is running. You can operate the automatic 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. Warning! Nearly all dust particles, pollutants and odors are filtered out before outside air enters the interior through the air distribution system. The air conditioning will not engage (no cooling) if the A/C mode is deactivated ( page 192). Warning! i Severe conditions (e.g. strong air pollution) may require replacement of the filter before its scheduled interval. A clogged filter will reduce the air volume to the interior. If the vehicle interior is hot, ventilate the interior before driving off. The climate control will then adjust the interior temperature to the set value much faster. Keep the air intake grille in front of the windshield free of snow and debris. When the retractable hardtop is closed, do not obstruct air flow by placing objects on the air flow-through exhaust slots below the rear window. G G When operating the automatic climate control, the air that enters the passenger compartment through the air vents can be very hot or very cold (depending on the set temperature). This may cause burns or frostbite on unprotected skin in the immediate area of the air vents. Always keep sufficient distance between unprotected parts of the body and the air vents. If necessary, use the air distribution controls ( page 192) to direct the air to air vents in the vehicle interior that are not in the immediate area of unprotected skin. 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. 193
