Rear Window Defroster and Heated Side View Mirrors (If equipped) The defroster for the rear window clears frost, fog, or thin ice from both the inside and outside of the rear window and activates the heated side view mirrors. The button for the rear window defroster and heated side view mirrors is on the instrument panel, to the right of the steering wheel. The rear window defroster and heated side view mirrors Clear away any snow that is on the rear window and side view mirrors before using the defroster. With the engine running, push the defroster button. After approximately 10 minutes, the defroster will turn off. If the window or mirrors are still not clear, turn the defroster on again. The defroster will turn off when the ignition key is turned to the OFF or START position. NOTE: Never use sharp instruments or window cleaners with abrasives to clean the inside of your rear window. If you do, you may damage the heating elements that are bonded to the inside of the rear window and cause damage to the rear window defroster. 74
