of the airflow. Press on the center vane
leading edge to shut off the air flow.

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.
.
Clear snow off the hood to improve
visibility and help decrease moisture
drawn 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.
