To Heat
Switch the fan on. Turn the temperature control dial clockwise, select
the position, and warmed air will begin flowing from the floor
outlet.
A small amount of warmed air will also flow from the windshield
defroster vent.
To warm up the interior quickly, push in the button so the
inside air will be recirculated to the heater.
If the windows begin to fog while heating in the setting, switch
