Heated Windshield Washer If your vehicle has the heated windshield washer fluid system it can be used to help clear ice, snow, tree sap, or bugs from the windshield. This feature only works with the front wiper system. The button is located to the left of the steering column below the instrument panel brightness control knob. When the heated windshield washer fluid system is activated under certain outside temperature conditions, steam might flow out of the washer nozzles for a short period of time before washer fluid is sprayed. This is a normal condition. WASHER FLUID LOW ADD FLUID is displayed on the DIC when the washer fluid is low. See DIC Warnings and Messages on page 3-66. Rear Window Wiper/Washer The rear wiper and rear wash button is located on the instrument panel below the climate control system. Push the heated washer fluid button to activate the heated windshield washer fluid system. This activation begins four heated wash/wipe cycles. The first heated wash/wipe cycle can take up to 40 seconds to occur, depending on outside temperature. After the first wash/wipe cycle, it can take up to 20 seconds for each of the remaining cycles. Press the button again to turn off the heated windshield washer fluid system or it will automatically turn off after four wipe cycles have been completed. Z (Rear Wiper): Press this symbol to turn the rear wiper on and off. The wiper speed cannot be changed. Y (Wash): Press this symbol to spray washer fluid on the rear window. The window wiper will also come on. Release the button when enough fluid has been sprayed on the window. The rear wiper will run a few more cycles after it is released. If the rear wiper function was already on, prior to pressing the wash button, it will stay on until the wiper button is pressed again. The rear window washer uses the same fluid that is in the windshield washer reservoir. See Windshield Washer Fluid on page 5-34. 3-11
