Rear Window Defogger The rear window defogger uses a warming grid to remove fog or frost from the rear window. The defogger only works when the ignition is on or during remote start, if programmed. See "Personal Settings Menu" under Vehicle Personalization on page 2-61 for additional information. The heated outside rearview mirrors also heat to help clear fog or frost from the surface of the mirror when the rear window defogger is on. See Outside Heated Mirrors on page 2-41. Notice: Do not use a razor blade or sharp object to clear the inside rear window. Do not adhere anything to the defogger grid lines in the rear glass. These actions may damage the rear defogger. Repairs would not be covered by your warranty. = (Rear Window Defogger): Press to turn the rear window defogger on or off. The rear window defogger stays on for 10 minutes, before turning off.
