Rear Window Defogger The rear window defogger uses a warming grid to remove fog from the rear window. If your vehicle has heated mirrors this button will also activate that feature. If your vehicle has the remote start feature, the rear defogger and heated mirrors will automatically be turned on if it is cold outside. The indicator light will not be on. When the vehicle transitions out of remote start mode the rear defogger and heated mirrors will turn off. 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): Press this button to turn the rear window defogger on or off. An indicator light above the button will come on to let you know that the rear window defogger is activated. If driving below 50 mph (80 km/h), the rear window defogger will turn off about 15 minutes after the button is pressed. If you need additional warming time, press the button again. If your vehicle's speed is maintained above 50 mph (80 km/h), the rear window defogger will remain on once the button is pressed. 198
