Use the louvers on the air outlets to change the direction of the airflow.
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. |
| • | 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. |
