Controls in detail Climate control The climate control 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. 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 ACOFF mode is selected ( page 157). Warning! i If the vehicle interior is hot, ventilate the interior before driving off. Keep the air intake grille in front of the windshield free of snow and debris. Setting the temperature Use temperature controls 2 and 3 to separately adjust the air temperature on each side of the passenger compartment. You should raise or lower the temperature setting in small increments, preferably starting at 72°F (22°C). Increasing Turn the temperature control a few degrees to the right. The climate control system will correspondingly adjust the interior air temperature. Decreasing Turn the temperature control a few degrees to the left. The climate control system will correspondingly adjust the interior air temperature. G i When operating the climate control system in automatic mode, you will only rarely need to adjust the temperature, air volume and air distribution. 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. 152
