• 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 pressed. This dehu-
midifies the air to help dry the windshield. To improve
fuel economy, use these modes only when necessary.
• 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.
• 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.
• Recirculated air is not allowed in Defrost modes. If the
Recirculation button is pressed while in Defrost mode,
the LED indicator will flash several times then go out.
Recirculation will be disabled automatically when
Defrost mode is selected.
• If the following conditions are verified:
• Mode Floor, Vent or Bi level selected.
• Temperature in Max Cold.
• A/C led ON.
