the extreme right position, turn the mode control to the
panel fresh position, press the snowflake button to turn

pushbutton on dual zone control, or switch the mode
from panel/fresh to panel/recirculate on single zone
control. When a comfortable condition has been reached,
choose a mode position and adjust the temperature
control slide and blower speed as necessary to maintain
comfort. For high humidity conditions it may be neces-

air direction and blower speed to maintain comfort.

direct air onto the windshield by using the Mix mode
position on the control. Adjust the temperature control
and blower speed to maintain comfort. Higher blower
