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.
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 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. |
