Operation Tips
Clear away any ice, snow,
or leaves from the air inlets at
the base of the windshield that
could block the flow of air into
the vehicle.
When you enter a vehicle in cold
weather, press the fan up button
to the maximum fan level before
driving. This helps clear the
intake ducts of snow and
moisture, and reduces the
chance of fogging the inside of
the window.
Keep the air path under the front
seats clear of objects to help
circulate the air inside of the
vehicle more effectively.
Use of non-GM approved hood
deflectors can adversely affect
the performance of the system.
Check with your dealer before
adding equipment to the outside
of the vehicle.
