All you need to do is set the desired temperature, and the air conditioning, air recirculation, air distribution, and fan speed automatically maintain your selected temperature. To override the automatic setting, touch Auto On to view the individual settings. Then touch the setting you want to change. When you change a setting, the Auto On icon turns from blue to gray and Reset Auto is displayed instead. 3. Touch one of these icons to specify how air is drawn into Model S: Outside air is drawn into Model S (see page 5.10). Although less efficient than recirculating the air in very hot or low climate conditions, this setting draws more air into the rear seating areas, and is recommended when occupants are seated in the Tesla built in rear facing child seats. Air inside Model S is recirculated. This prevents outside air (traffic fumes) from entering but reduces dehumidifying and cooling performance. Recirculating the air is the most efficient way to cool the front cabin area but it is also the loudest. To prevent the windshield from fogging in some conditions, 1.

Because Model S runs much quieter than a Foot-level vents gasoline-powered vehicle, you may notice the sound of the compressor as it is Face-level vents operating. To minimize noise, reduce the fan speed or recirculate the air. NOTE: Turning off air conditioning can Windshield vents cause the windows to fog in some climate conditions. 5. Touch and drag the slider to set the speed of the fan. NOTE: In high temperatures, it is more efficient to operate the fan at a higher speed. Doing so reduces the amount of power needed by the air conditioning system. USING THE TOUCHSCREEN 5.9
