Rear Window Defogger If your vehicle has this feature, the rear window defogger uses a warming grid to clear fog from the rear window. The button is located on the center of the instrument panel, near the vehicle's comfort controls. The rear window defogger will turn off automatically about 15 minutes after the button is pressed. The defogger can also be turned off by pressing the button again or by turning off the engine. Notice: Using a razor blade or sharp object to clear the inside rear window may damage the rear window defogger. Repairs would not be covered by your warranty. Do not clear the inside of the rear window with sharp objects. Outlet Adjustment Use the air outlets located in the center and outboard sides of the instrument panel, to change the direction and amount of the air flowing through the vents. The rear window defogger will only work when the ignition is in ON. =(Rear Defogger): Press the defogger button to turn the rear window defogger on or off. An indicator light in the button will come on to let your know that the rear window defogger is activated. Be sure to clear as much snow from the rear window as possible. 3-22
