Jeep 2008 Wrangler - Manual (Page 263)

Panel
Air is directed through the outlets in the instrument
panel. These outlets can be adjusted to direct airflow.
Bi-Level
Air is directed through the panel and floor outlets.
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 demist outlets with a small amount
through the defrost outlet.
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 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 demist outlets. Use this mode with maxi-
mum fan and temperature settings for best windshield
and side window defrosting.
NOTE: The air conditioning compressor operates in
both Mix and Defrost or a blend of these modes even if
the fan switch is not in the A/C position. This dehumidi-
fies the air to help dry the windshield. To improve fuel
economy, use these modes only when necessary.
