Outlet Adjustment
Use the thumbwheel below the air
outlets to change the direction of the
air flow. Use the vertical thumbwheel
next to the outlets to control the
amount of air flow or to shut off the
airflow completely.
Keep all outlets open whenever
possible for best system
performance.
Operation Tips
• Clear away any ice, snow, or
leaves from the air inlets at
the base of the windshield that
can block the flow of air into
the vehicle.
• Use of non-GM approved hood
deflectors can adversely affect
the performance of the system.
• Keep the path under all seats
clear of objects to help circulate
the air inside the vehicle
more effectively.
• If fogging reoccurs while in vent
or bi-level modes with mild
temperature throughout the
vehicle, turn on the air conditioner
to reduce windshield fogging.
