5. Modes
The airflow distribution mode can be adjusted so air
comes from the instrument panel outlets, floor outlets,
demister outlets and defrost outlets. The Mode settings
are as follows:•Panel Mode
Air comes from the outlets in the instrument
panel. Each of these outlets can be individually
adjusted to direct the flow of air. The air vanes of
the center outlets and outboard outlets can be moved up
and down or side to side to regulate airflow direction.
There is a shut off wheel located below the air vanes to
shut off or adjust the amount of airflow from these
outlets.
•Bi-Level Mode
Air comes from the instrument panel outlets and
floor outlets. A slight amount of air is directed
through the defrost and side window demister
outlets. NOTE:
BI-LEVEL mode is designed under comfort con-
ditions to provide cooler air out of the panel outlets and
warmer air from the floor outlets.
•Floor Mode
Air comes from the floor outlets. A slight amount
of air is directed through the defrost and side
window demister outlets.
• Mix Mode
Air comes from the floor, defrost and side window
demister outlets. This mode works best in cold or
snowy conditions.
NOTE: The air conditioning compressor operates in MIX
and DEFROST modes even if the A/C button is not
pressed. This dehumidifies the air to help dry the wind-
shield. To improve fuel economy, utilize these modes
only when required.
