Rear Window Defogger
(omorv)
The rear window defogger uses a
warming grid to remove fog from the
rear window. Push the
@
button up
to turn on the defogger. The defogger
will turn off automatically after about 10
minutes of use. If you turn it on again,
the defogger will operate for about five
minutes only. You can also turn the
defogger off by pushing the button down
or by turning off the ignition.
Do not attach a temporary vehicle
license across the defogger grid on the
rear window.
Don't use a razor blade or something
else sharp on the inside of the rear
window. If you do, you could cut
or damage the warming grid, and
the repairs wouldn't be covered by
your warranty.
Your Pontiac's flow-through ventilation
system supplies outside air into the
vehicle when it is moving. Outside air
will also enter the vehicle when the
heater or the air conditioning fan is
running.
