UNDERSTANDING THE FEATURES OF YOUR VEHICLE 149 If the liftgate flipper glass is open, connection to the rear window wiper is interrupted preventing activation of the rear wiper blade. When the liftgate flipper glass is closed, the rear wiper switch, or the ignition switch, needs to be turned OFF and ON to restart the rear wiper. Rear Window Defroster The rear window defroster button is located on the climate control panel. Press this button to turn on the rear window defroster and the heated outside mirrors (if equipped). An indicator in the button will illuminate when the rear window defroster is on. The rear window defroster automatically turns off after approximately 10 minutes. For an additional five minutes of operation, press the button a second time. NOTE: To prevent excessive battery drain, use the rear window defroster only when the engine is operating. CAUTION! Failure to follow these cautions can cause damage to the heating elements: • Use care when washing the inside of the rear window. Do not use abrasive window cleaners on the interior surface of the window. Use a soft cloth and a mild washing solution, wiping parallel to the heating elements. Labels can be peeled off after soaking with warm water. • Do not use scrapers, sharp instruments, or abrasive window cleaners on the interior surface of the window. • Keep all objects a safe distance from the window. 3
