The rear window defogger will turn off about
15 minutes after the button is pressed. If turned on
again, the defogger will only run for about seven
minutes before turning off. If the vehicle is
moving faster than 50 mph (80 kph), the rear
defogger will stay on. The defogger can also be
turned off by pressing the button again or by
turning off the engine.
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
Use the thumbwheels located next to and below
the air outlets to change the direction of the airflow
and to open and close the outlets.
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.
