8-6 Climate Controls
Caution
Using a razor blade or sharp
object to clear the inside rear
window can damage the rear
window defogger. Repairs would
not be covered by the vehicle
warranty. Do not clear the inside
rear window with sharp objects.
Heated Mirror: If equipped with
heated outside rearview mirrors, the
mirrors heat to help clear fog or frost
from the surface of the mirror when
the rear window defog button is
pressed. See Heated Mirrors on
page 2-14.
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.
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.
