Operation Tips
.
Clear away any ice, snow,
or leaves from air inlets at the
base of the windshield that could
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 paths 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.
.
Do not attach any devices to the
air vent louvers. This restricts
airflow and may cause damage
to the air vents.
