Outlet Adjustment 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 your vehicle. • Use of non-GM approved hood deflectors may adversely affect performance of the system. • Keep the path under the front seats clear of objects to help circulate the air inside of your vehicle more effectively. • When an objectionable odor outside the vehicle is Use the horizontal thumbwheels on the air outlets, located in the center and on the sides of the instrument panel, to change the direction of the airflow. Airflow can be shut off at the center upper outlet by turning the vertical thumbwheel. The other outlets can be shut off by closing the outlet vanes. The two upper outlets in the center of the instrument panel are dedicated to the rear seats. These outlets are fixed to aim airflow into the rear seats to help cool occupants in hot weather. The louvers are fixed, do not attempt to move them or they may break. encountered, use the recirculation mode, with the temperature knob at a comfortable setting to prevent the odor from entering the vehicle through the ventilation system. This can be helpful when driving through a long tunnel with poor ventilation. However, extended usage of this mode in cold or cool weather can cause window fogging. 3-30
