Rear Window Defogger
(Rear Defogger):
Press this button to
warm the defogger
grid on the rear
window. An indicator
light below the button
will glow while the
rear window defogger
is operating.
At speeds above 30 mph (48 km/h), the rear defogger
will stay on until you press the rear button again. At
speeds below 30 mph (48 km/h), the rear defogger will
turn off automatically after about 10 minutes of use. If
you press it again, the defogger will operate for about
five minutes only. You can also turn the defogger off
by turning off the ignition.
Do not attach a temporary vehicle license across the
defogger grid on the rear window.
If your vehicle is equipped with heated outside rearview
mirrors, when you operate the rear window defogger,
the mirrors are also heated to help remove ice and fog.
For more information see “Heated Outside Rearview
Mirrors” in the Index.
NOTICE:
Don’t use a razor blade or other sharp object 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.
Ventilation System
Your vehicle’s flow-through ventilation system allows
filtered outside air to flow through your vehicle while it
is moving, even if the system is off.
The direction of the airflow
can be controlled by
adjusting/closing the outlets
in the instrument panel.
