Dodge 2009 Caliber - Manual (Page 240)

NOTE: There is a difference in temperature 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
Air is directed through the floor outlets and side
window demister outlets with a small amount
through the defrost outlet.
Mix
Air is directed through the floor, defrost and side
window demister 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
Air is directed through the windshield and side
window demister outlets. Use this mode with
maximum fan and temperature settings for best wind-
shield and side window defrosting.
NOTE: The air conditioning compressor operates in
both Mix and Defrost modes even if the Air Conditioning
Snowflake button is not pressed. This dehumidifies the
air to help dry the windshield. To improve fuel economy,
use these modes only when necessary.
Air Outlets
The airflow from each of the instrument panel outlets can
be adjusted for direction and turned ON or OFF to
control air flow.
