• 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, Floor, or a blend of these modes, even if the
Air Conditioning (A/C) button is not pressed. This
dehumidifies the air to help dry the windshield. To
improve fuel economy, use these modes only when
necessary.
• Recirculation Control
Use this button to block the flow of outside air
from coming into the passenger compartment.
A light will illuminate when the system is in
recirculation mode. Only use the recirculation
mode as a temporary means to 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:
• 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 build-up inside the vehicle. Select
the Outside Air position for maximum defogging.
• The A/C will engage automatically to prevent fogging
when the recirculation button is pressed and the mode
control is set to panel or panel / floor.
