The Rainsense system can be activated by turning the wiper band to one of the five sensitivity levels indicated on the wiper stalk. The position closest to OFF is the lowest sensitivity setting, level one. This allows more rain or snow to collect on the windshield between wipes. Turning the wiper band away from you to higher sensitivity levels increases the sensitivity of the system and frequency of wipes. The highest sensitivity setting, level five is closest to LO. A single wipe will occur each time you turn the wiper stalk to a higher sensitivity level to indicate that the sensitivity level has been increased. 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 LO or HI speed. 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. NOTICE: The wipers must be turned off when going through a car wash to avoid damage. 2-45
