Rear Window Defogger (Option)
The rear window defogger
uses a warming grid to
remove fog from the rear
window. Press the defogger
switch. The indicator light
will glow.
If
your vehicle is traveling under
45 mph (70 krn/h),
the
rear window defogger will turn off automatically after
about 10 minutes of use. If your vehicle is traveling over
45 mph (70
km/h),
the defogger will operate continuously.
You
can
tum the defogger off by turning off the ignition
or
pressing the switch again.
Do not attach a temporary vehicle license across the
defogger grid
on
the rear window.
I
NOTICE:
Don't use a razor blade or anything 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.
