The level one or lowest setting is at the bottom of the band. This setting lets more rain or snow collect on the windshield between wipes. Turn the delay band forward to a higher setting to let less rain or snow collect on the windshield between wipes. The top position is the highest setting. A single wipe occurs each time the delay band is turned to a higher setting to indicate that the Rainsense 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. The system will default to normal time delay operation if the Rainsensor detects something that would affect Rainsense operation. When Rainsense is active, the headlamps turn on automatically. If it is dark, they remain on. See "Wiper-Activated Headlamps" under Wiper Activated Headlamps on page 3-17 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. Windshield Washer { 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. K (Washer Fluid): Press the button with this symbol, located at the end of the windshield washer lever, to wash the windshield. The washer fluid sprays onto the windshield and the wipers run for a few cycles to clear the windshield. Press and hold K for more wash cycles.
