Windshield Wipers You control the windshield wipers by turning the band with the wiper symbol on it. 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. Windshield Washer At the top of the multifunction lever there's a paddle marked with the windshield washer symbol and the word PUSH. To spray washer fluid on the windshield, press the paddle. The wipers will clear the window and then either stop orreturn to your preset speed. For a singlewiping 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. A CAUTION: In freezing weather, don't use your washer until the windshield is warmed. Otherwise the washer fluid can form ice on the windshield, blocking your vision. 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 LOW, the shorter the delay. For steady wiping at low speed, turn the band away from you to the LOW position. For high-speed wiping, turn the band further, to HIGH. To stop the wipers, move the band to OFF. 2-39
