remove fog from the rear window.
<(Rear Window Defogger):Press this button
to turn the rear window defogger on or off. The
rear window defogger stays on for about

the engine. Do not drive the vehicle until all the
windows are clear.
If your vehicle has heated outside rearview

Notice:Do not use a razor blade or sharp
object to clear the inside rear window. Do not
adhere anything to the defogger grid lines
in the rear glass. These actions may damage
the rear defogger. Repairs would not be
covered by your warranty.
Outlet Adjustment
Use the slider switch in the center of the outlet,
to change the direction of the air ow. Use
the thumbwheel near the outlet to control the
amount of air ow or to shut off the air ow
completely.
Keep all outlets open whenever possible for best
system performance.
Operation Tips
Clear away any ice, snow, or leaves from the
air inlets at the base of the windshield that
can block the ow of air into the vehicle.
Use of non-GM approved hood de ectors can
adversely affect the performance of the
system.
Keep the path under all seats clear of objects
to help circulate the air inside the vehicle
more effectively.
If fogging reoccurs while in vent or bi-level
modes with mild temperature throughout
the vehicle, turn on the air conditioner
to reduce windshield fogging.
