9. Recirculation Control Button
Press this button to choose between outside air
intake or recirculation of the air inside the
vehicle. A lamp will illuminate when you are in
Recirculation mode. Only use the Recirculation
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.
NOTE:
• If the Recirculation button is pressed when the system
is in Defrost mode the Recirculation LED indicator will
flash 3 times to indicate Recirculation mode is not
allowed.
• In Floor and Mix mode the system will turn off
Recirculation mode after five minutes of operation.
You can select Recirculation mode again if desired.
• Continuous use of the Recirculation mode may make
the inside air stuffy and window fogging may occur.
Extended use of this mode is not recommended.
• In cold or damp weather, the use of the Recirculation
mode will cause windows to fog on the inside because
of moisture buildup inside the vehicle. For maximum
defogging, select the outside air position.
