You can tell if your vehicle has this option by looking at the rear window. If
you see lines running across the glass, you have it. These are the wires
which heat your window.
NOTICE
I Scraping the inside of your rear window could cut and damage the
defogger. Your warranty would not cover this damage. And don't put
decals there, you might have
to scrape them off. I
For best results, clear the window of as much snow or ice as possible first.
