Air Vents
Adjustable air vents are in the center and on
the side of the instrument panel. Use the
sliding knobs on the air vents to change the
direction of the airflow. Slide the knob up or
down to open or close off the airflow.
Air vents blow warm air on the side
windows in cold weather. If Floor, Defog,
or Defrost modes are selected, a small
amount of air will come from the vents
close to the window. If the airflow is shut
off using the sliding knobs, warm air will be
directed to the other instrument panel
vents. This is normal operation.
Use the sliding knobs to turn vent airflow
on or off based on the mode selected.
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 the 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.
.
Do not attach any devices to the air vent
slats. This will restrict airflow and may
cause damage to the air vents.
