The Rainsense™ system is activated by turning the wiper control band to one of the five sensitivity levels within the delay area. The delay position closest to OFF is the lowest sensitivity setting, level one. The highest sensitivity setting, level five, is closest to LO. A single wipe will occur each time you turn the wiper control band to a higher sensitivity level to indicate that the sensitivity level has been increased. Notice: Going through an automatic car wash with the wipers on can damage them. Turn the wipers off when going through an automatic car wash. The MIST and wash cycles operate as normal and are not affected by the Rainsense™ function. The system can be overridden at any time by manually changing the wiper control to LO or HI speed. Notice: Do not place stickers or other items on the exterior glass surface directly in front of the rain sensor. Doing this could cause the rain sensor to malfunction. Windshield Washer At the top of the turn signal/multifunction lever, there is a paddle with the word PUSH on it. To spray washer fluid on the windshield, push the paddle. The wipers will clear the window and either stop or return to your preset speed. For more washer cycles, push and hold the paddle. {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. Ice build up can block washer nozzles. Remove ice for proper operation. See Windshield Washer Fluid on page 5-34 for more information. 3-10
