NOTE: 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 de-
fogging, select the Outside Air position.
NOTE: The “Recirculation” mode will not operate in the
floor, mix or defrost modes.
