NOTE:
When air is directed to the foot-level vents, approximately one third of the air
continues to flow to the windshield vents to assist in defogging. However, when air is
directed to the face-level vents, air does not flow to the windshield because the air flowing
through the face-level vents can assist in defogging the windshield.
5. If your Model S is equipped with the Bioweapon Defense Mode feature, the HEPA (High
Efficiency Particulate Air) filter ensures the best possible quality of air inside the cabin.
When selected, outside air is filtered through the medical-grade HEPA filter in addition to
the secondary filtration systems. The HEPA filter is extremely effective at removing particles,
including pollution, allergens, bacteria, pollen, mold spores, and viruses. Both the HEPA filter
and the secondary filtration system also contain activated carbon to remove a broad
spectrum of odors and gases. When you engage Bioweapon Defense Mode, the fan
operates at the highest speed. In addition, the positive pressure inside the cabin minimizes
the amount of outside air that can leak into the vehicle.
NOTE:
Some gases, such as carbon monoxide, are not effectively removed by activated
carbon.
6. Choose how air is drawn into Model S:
Outside air is drawn into Model S (see
). Although less efficient than recirculating the
air in very hot or cold 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 performance. Recirculating the air is the
most efficient way to cool the front cabin area. To prevent
the windshield from fogging in some conditions, briefly
change the setting every hour to draw in outside air.
7. Touch
AUTO
to change all settings back to their default values. The icon is blue whenever
the climate control system is set to
AUTO
.
NOTE:
Because Model S runs much quieter than a gasoline-powered vehicle, you may notice the
sound of the A/C compressor as it is operating. To minimize noise, reduce the fan speed.
