Dodge 2009 Caravan - Manual (Page 306)

NOTE: There is a difference in temperature (in any
conditions other than full cold or full hot), between the
upper and lower outlets for added comfort. The warmer
air goes to the floor outlets. This feature gives improved
comfort during sunny but cool conditions.
Floor Mode
Air is directed through the floor outlets with a
small amount through the defrost and side window
demist outlets.
Mix Mode
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 at
the windshield. This setting is good for maintaining
comfort, while reducing moisture on the windshield.
Defrost Mode
Air is directed through the windshield and side
window demist outlets. Use DEFROST mode with
maximum blower and temperature settings for best
windshield and side window defrosting.
NOTE: The air conditioning compressor operates in
MIX and DEFROST, or a blend of these modes even if the
A/C SNOWFLAKE button is not pressed. This dehu-
midifies the air to help dry the windshield. To improve
fuel economy, use these modes only when necessary.
