Air Vents

Move the sliding knob on the air outlets up and down or left and right 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 the vehicle more effectively.

- Use of non—GM approved hood deflectors can adversely affect the performance of the system.

Check with your dealer before adding equipment to the outside of the vehicle.

- Do not insert any objects in the outlets, as failure of the mechanism may occur.
