Rear Window Defogger
Press the button marked
REAR to turn the 
defogger on. An indicator 
in the button will light.
When turned on, the rear window defogger uses a
warming grid to remove fog from the rear window. 
If your vehicle has the optional heated outside mirrors,
they will heat to clear the surface of the mirrors.
The rear window defogger and the outside rearview
mirrors will automatically turn off after about 15 minutes.
If you turn them on again, the defogger and the outside
rearview mirrors will only stay on for about seven and
one half minutes before turning off again. You can also
turn them off by turning the ignition off or by pressing
the button again.
Do not attach anything like a temporary vehicle license
or decal across the defogger grid.
NOTICE:
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.
Don’t put decals there because you might have to
scrape them off.
