Rear Window Defogger
The rear window defogger
uses a warming grid to
remove fog from the
rear window.
Press the defogger button. The indicator light will glow.
The rear window defogger will turn itself off after about
10 minutes after the first time the button is pressed, and
after five minutes each additional time the button is
pressed. You can turn the defogger off by pressing the
button again or turning off the ignition.
Do not attach a temporary vehicle license across the
defogger grid on the rear window.
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.
