Rear Window Defogger
= (Rear Window Defogger):
Press to turn the rear window

The rear window defogger turns off
automatically after about
10 minutes. If turned on again it

to ACC/ACCESSORY or

The rear window defogger can be
set to automatic operation. See
“Climate and Air Quality” under
Vehicle Personalization on
page 5‑40. When auto rear defog is
selected, the rear window defogger
turns on automatically when the
interior temperature is cold and
the outside temperature is about
4°C (40°F) and below.
The auto rear defogger turns
off automatically after about
10 minutes, or after five minutes if
the outside temperature is not
as cold.
For vehicles with heated outside
rearview mirrors, they turn on when
the rear window defogger button is
on and help to clear fog or frost from
the surface of the mirror. See
Heated Mirrors on page 2‑17.
Notice: Do not try to clear frost
or other material from the inside
of the front windshield and rear
window with a razor blade or
anything else that is sharp. This
may damage the rear window
defogger grid and affect your
radio's ability to pick up stations
clearly. The repairs would not be
covered by your warranty.
