Heating

For the quickest results, press the recirculate button
and move the mode knob to the floor mode. Turn the
temperature knob clockwise for warmer air and turn the
fan knob toward HI. You should switch to outside air
once in a while to avoid stale air and cloudy windows.
To prevent cold air from blowing in and to increase air
flow to the floor area, you may shut off the outer dash
vents by using the thumbwheels.

You may want to use bi level heating on cool but sunny
days. This setting directs outside air toward your body
and warmer air toward your feet.
Using outside air, turn the mode knob to the bi
mode. Turn the temperature knob counterclockwise and
the fan knob toward HI.
