Use the slider knobs (1) on the air
vents to change the direction of the
airflow.

air vents to control the amount of
airflow or to shut off the airflow.

and in the foot wells.
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.
Clear snow off the hood to
improve visibility and help
decrease moisture drawn into
the vehicle.
Keep all outlets open whenever
possible for best system
performance.
Keep the path under all seats
clear of objects to help circulate
the air inside the vehicle more
effectively.
Use of non-GM approved hood
deflectors can adversely affect
the performance of the system.
