• Mix
Air is directed through the floor, defrost, and side
window demist outlets. This setting works best in
cold or snowy conditions that require extra heat to the
windshield. This setting is good for maintaining comfort
while reducing moisture on the windshield.
• Defrost
Air is directed through the windshield and side
window demist outlets. Use this mode with maxi-
mum blower and temperature settings for best wind-
shield and side window defrosting.
NOTE:
The air conditioning compressor operates in Mix,
Defrost, or a blend of these modes, even if the Air
Conditioning (A/C) button is not pushed. This dehu-
midifies the air to help dry the windshield. To improve
fuel economy, use these modes only when necessary.
Recirculation Control
Pushing the Recirculation Control button will
put the system in recirculation mode. This can
be used when outside conditions such as
smoke, odors, dust, or high humidity are pres-
ent. Activating recirculation will cause the LED in the
control button to illuminate.
Continuous use of the Recirculation mode may make the
inside air stuffy and window fogging may occur. Ex-
tended use of this mode is not recommended.
The use of the Recirculation mode in cold or damp
weather will cause windows to fog on the inside, because
of moisture buildup inside the vehicle. Select the outside
air position for maximum defogging.
