Outlet Adjustment Use the thumbwheel on the outlets to change the direction of the air flow. Lift up or push down on the thumbwheel located in the center of the outlet to direct the air up or down, or slide the thumbwheel to the left or right to direct the airflow from side-to-side. Warning Lights, Gages, and Indicators Warning lights and gages can signal that something is wrong before it becomes serious enough to cause an expensive repair or replacement. Paying attention to the warning lights and gages could prevent injury. Warning lights come on when there may be or is a problem with one of the vehicle's functions. Some warning lights come on briefly when the engine is started to indicate they are working. Gages can indicate when there may be or is a problem with one of the vehicle's functions. Often gages and warning lights work together to indicate a problem with the vehicle. When one of the warning lights comes on and stays on while driving, or when one of the gages shows there may be a problem, check the section that explains what to do. Follow this manual's advice. Waiting to do repairs can be costly and even dangerous. Operation Tips • Clear away any ice, snow or leaves from the air inlets at the base of the windshield that may block the flow of air into the vehicle. • Use of non-GM approved hood deflectors may adversely affect the performance of the system. • Keep the path under the front seats clear of objects to help circulate the air inside of the vehicle more effectively. 3-20
