RainsenseTM Wipers II If your vehicle has this feature, the moisture sensor is mounted on the interior of the windshield below the rearview mirror and is used to automatically operate the wipers. This system operates by monitoring the amount of moisture build-up on the windshield. Wipes occur as needed to clear the windshield depending on the driving conditions and the sensitivity setting. In light rain or snow, fewer wipes will occur. In heavy rain or snow, wipes will occur more frequently. The system will operate in the delay, low speed and high speed modes. If the system is left on for long periods of time, occasional wipes may occur without any moisture on the windshield. This is normal and indicates that the RainsenseTM system is active. The system can be overridden at any by manually time changing the wiper control to LO or HI speed. Notices Do not place stickers or other items on the exterior glass surface directly in front of the rainsensor. Doing this could cause the rainsensor to malfunction. Windshield Washer At the top of the turn signaVmultifunctionlever, there's a paddle with the word PUSH on it. To spray washer fluid on thewindshield, push the paddle. The wipers clear will the window andeither stop orreturn to your preset speed. For more washer cycles, push andhold the paddle. The RainsenseTM systemis activated by turning the wiper control band to one of the five sensitivity levels within the delay area. The delay position closest to OFF/MIST is the lowest sensitivity setting, level one. The highest sensitivity setting, level five, is closest to the LO position. 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: The wipers must be turned off when going through a car wash to avoid damage. In freezing weather, don't use I lr 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 5-39 for more information. The MIST and wash cycles operate as normal and are not affected by the RainsenseTMfunction. 3-8
