The mist and wash cycles operate as normal and are not affected by the Rainsense™ function. The Rainsense™ system can be overridden at any time by manually turning the wiper band to low or high speed. When Rainsense™ is active, the headlamps will turn on automatically. The headlamps will turn off again once the wipers turn off if it is light enough outside. If it is dark, they will remain on. See Wiper Activated Headlamps on page 215. Notice: Do not place stickers or other items on the exterior glass surface directly in front of the moisture sensor. Doing this could cause the moisture sensor to malfunction. {CAUTION: In freezing weather, do not use your washer until the windshield is warmed. Otherwise the washer fluid can form ice on the windshield, blocking your vision. If the fluid in the windshield washer fluid reservoir is low, the message CHECK WASHER FLUID will appear on the Driver Information Center (DIC) display. It will take 60 seconds after the bottle is refilled for this message to turn off. For information on the correct washer fluid mixture to use, see Windshield Washer Fluid on page 404 and Recommended Fluids and Lubricants on page 516. Windshield Washer K (Washer Fluid): The lever on the right side of the steering column also controls the windshield washer. There is a button at the end of the lever. To spray washer fluid on the windshield, press the button and hold it. The washer will spray until you release the button. The wipers will continue to clear the window for about six seconds after the button is released and then stop or return to your preset speed. 191
