Rainsense™ Wipers Your vehicle has Rainsense™ wipers. The moisture sensor for this feature is mounted on the interior side of the windshield below the rearview mirror and is used to automatically operate the wipers by monitoring the amount of moisture build-up on the windshield. Wipes occur as needed to clear the windshield depending on 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 Rainsense™ wipers operate in a delay mode as well as a continuous low or high speed as needed. 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 Rainsense™ system is activated. The Rainsense™ system is also sensitive to vibration. The system may activate if something hits the windshield or if the vehicle hits a bump. The Rainsense™ system can be activated by moving the wiper lever up to the delay position and turning the delay adjust band to one of the five sensitivity levels. The bottom delay adjust position is the lowest sensitivity setting, level one. This allows more rain or snow to collect on the windshield between wipes. Turning the delay adjust band away from you to the higher sensitivity levels allows less rain or snow to collect on the windshield between wipes. The top position is the highest sensitivity setting, level five. A single wipe will occur each time you turn the delay adjust 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 Rainsense™ system can be overridden at any time by manually changing the wiper control to low or high speed. When Rainsense™ is active, the headlamps will turn on automatically. If it is dark, they will remain on. See "Wiper-Activated Headlamps" under Exterior Lamps on page 3-24 for more information. 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. 3-10
