Front Defrost Setting
Turn the Mode Control knob to the Defrost mode. Air comes from the windshield and side win-
dow demist outlets. When the defrost button is selected, the blower level will increase. Use De-
frost mode with maximum temperature settings for best windshield and side window defrosting
and defogging. Performing this function will cause the ATC to switch into manual mode. If the
front defrost mode is turned off the climate system will return the previous setting.
Rear Defrost Button
Push and release the Rear Defrost Control button to turn ON the rear window defroster and the
heated outside mirrors (if equipped). An indicator will illuminate when the rear window de-
froster is ON. The rear window defroster automatically turns OFF after 10 minutes.
Temperature Control
Use this control knob to regulate the temperature of the air inside the passenger compartment.
Rotating the knob counterclockwise, from top center into the blue area of the scale, indicates
cooler temperatures. Rotating the knob clockwise, into the red area, indicates warmer tempera-
tures.
Blower Control
There are seven blower speeds. Use this control knob to regulate the amount of air forced
through the system in any mode you select. The blower speed increases as you move the con-
trol clockwise from the OFF position.
NOTE:Depending on the configuration, your vehicle may be equipped with four blower
speeds.

Modes Control
Rotate the Mode Control Knob to change the airflow distribution mode. The airflow distribution
mode can be adjusted so air comes from the instrument panel outlets, floor outlets, defrost out-
lets and demist 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 conditions to provide cooler air out of the panel out-
lets 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 is directed through the floor, defrost, and side window demister 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.
