OFF: Turn the band to turn off the windshield wipers. LOW (Low Speed): Turn the band to LOW for steady wiping at low speed. HIGH (High Speed): Turn the band to HIGH for steady wiping at high speed. DELAY:Turn the band to one of the five delay settings located between OFF and LOW, to choose the delayed wiping cycle. The closer the band is turned to OFF, the shorter the delay will be. For fewer wipes choose a setting closer to LOW. Use this setting for light rain and snow. 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 There is a paddle marked with the windshield washer symbol at the top of the malfunction lever. To spray washer fluid on the windshield, press the paddle. The wipers will clear the window and then either stop or return to your preset speed. 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. The wipers will clear the window and then either stop or return to your preset speed. 2-36
