Outlet Adjustment

Use the air outlets located in the center and on the side
of the instrument panel to direct the airflow. Use the
thumbwheels near the air outlets to open or close off
the airflow.
Operation Tips
•
Clear away any ice, snow, or leaves from air inlets
at the base of the windshield that could block the
flow of air into the vehicle.
•
Keep the path under the front seats clear of objects
to help circulate the air inside of the vehicle more
effectively.
•
Use of non-GM approved hood deflectors can
adversely affect the performance of the system.
Check with your dealer/retailer before adding
equipment to the outside of your vehicle.

Rear Climate Control System

Your vehicle has one of the following rear climate
control systems. With either of these systems, the rear
climate controls will be disabled when the front
climate control system is in defrost. This occurs to
provide maximum airflow to clear the windshield.
