Rear Window and Outside Mirror
Defogger
Your vehicle may have a rear window and outside
mirror defogger. This feature will only work when
the ignition is turned to ON.
The rear window defogger uses a warming grid to
remove fog or frost from the rear window. Before
using this feature, clear as much snow from the rear
window as possible.
<(Rear Window Defogger): Press this button
to turn the rear window and outside mirror defogger
on or off. An indicator light in the button will come
on to let you know that the feature is activated.
If your vehicle does not have air conditioning, the
rear window defogger will remain on until the button
is pressed again or the engine is turned off.
If your vehicle has air conditioning, the rear window
defogger will turn off about 10 minutes after the
button is pressed. The defogger can also be turned
off by pressing the button again or by turning the
engine off.
Notice: Do not use anything sharp on the
inside of the rear window. If you do, you could
cut or damage the warming grid, and the
repairs would not be covered by your warranty.
Do not attach a temporary vehicle license,
tape, a decal or anything similar to the
defogger grid.
Outlet Adjustment
To open an outlet, press on its cover. Turn the
cover to change 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 your 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 your
vehicle more effectively.
