The system operates in the delay mode. 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 active. The Rainsense system is activated by turning the wiper control band to one of the five sensitivity levels within the delay area. 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 low. 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. 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 cycle operates 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 low or high speed. Notice: Do not place stickers or other items on the exterior glass surface directly in front of the rain sensor. ™ Windshield Washer { WARNING: 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. J (Washer Fluid): Press and release this paddle, located at the top of the turn signal/multifunction lever, to spray washer fluid on the windshield. The wipers will clear the windshield and either stop or return to the preset speed. For more washer cycles, press and hold the paddle. 4-11
