Circulation Control
Use this control to choose be-
tween outside air intake or
recirculation of the air inside
the vehicle. Only use the re-
circulate mode to temporarily
block out any outside odors,
smoke, or dust and to cool the
interior rapidly upon initial
start up in very hot or humid
weather.
This control only operates in the Outside Air and Recir-
culate modes; there is no in between position. Do not
place the control between these positions.
NOTE:
Continuous use of the recirculate mode may
make the inside air stuffy and window fogging may
occur. Extended use of this mode is not recommended.
In cold weather, the use of the Recirculate position will
cause windows to fog on the inside because of moisture
build up inside the vehicle. For maximum defogging,
select the Outside Air position.
If the mode control is in the range between Mix and
Defrost and you choose the Recirculate mode, the mode
control knob will automatically move to the Mix position.
NOTE:
If you choose either the Mix or Defrost modes
and the Circulation control is in the Recirculate Mode, the
system will automatically switch to the Outside Air
position.
