Outlet Adjustment Use the louvers on the air outlets to change the direction of the airflow. 0 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 encountered, use the MAX 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. 0 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 the performance of the system. 3-2 1
