(Rear Window Defogger): Press this button to
turn the rear window defogger on and off. Be sure
to clear as much snow from the rear window as possible.

turning off. The defogger can also be turned off
by pressing the button again or by turning off the engine.
Do not drive the vehicle until all the windows are clear.
Notice: Do not use a razor blade or sharp object to
clear the inside rear window. Do not adhere

These actions may damage the rear defogger.

outlets to open and close the outlets. Move the lever in
the center of each air outlet to adjust the direction of
the airflow.
Operation Tips
•
Clear away any ice, snow or leaves from the air
inlets at the base of the windshield that may
block the flow of air into the vehicle.
•
Use of non-GM approved hood deflectors may
adversely affect the performance of the system.
•
Keep the path under the front seats clear of objects
to help circulate the air inside of the vehicle more
effectively.
•
This vehicle has a passenger compartment air filter.
If the airflow seems low when the fan is at the
highest setting it may need to be replaced. For more
information, see Passenger Compartment Air
Filter on page 3-29.
