Windshield Wipers (Mist): For a single wiping cycle, turn the band to mist. Hold it there until the wipers start. Then let go. The wipers will stop after one wipe. If you want more wipes, hold the band on mist longer. RainsenseTM Wipers Your vehicle may be equipped with RainsenseTM windshield wipers. When active, these wipers are able to detect moisture on the windshield and automatically turn on the wipers. The moisture sensor is located next to the inside rearview mirror and is mounted on the windshield. To turn on the RainsenseTM feature, the wipers must be set to one of the five delay settings on the multifunction lever. Each of the five settings adjusts the sensitivity of the rainsensor. For more wipes, select the higher settings; for fewer wipes, select the lower settings located closer to off on the multifunction lever. The rainsensor will automatically control the frequency of the wipes from off to high speed according to the weather conditions. The wipers can be left in a rainsense mode even when it is not raining. 0 (Off): To stop the wipers, move the band to off. (Windshield Wipers): Turn the band to control the windshield wipers. You can set the wiper speed for a long or short delay between wipes. This can be very useful in light rain or snow. Turn the band to choose the delay time. The closer to the top of the lever, the shorter the delay. For steady wiping at lowspeed, turn the band away from you to the first solid band past the delay settings. For high-speed wiping, turn the band further, to the second solid band past the delay settings. To stop the wipers, move the band to off. Be sure to clear ice and snow from the wiper blades before using them. If they're frozen to the windshield, carefully loosen or thaw them. If your blades do become worn or damaged, get new blades or blade inserts. Notice: Turn the windshield wiper band on the multifunction lever to off to avoid wiper damage when going through an automatic car wash. 3-9
