Windshield Wipers For steady wiping at low speed, turn the band to LO. For high-speed wiping, turn the band further, to HI. To stop the wipers, turn the band to OFF. 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 LO, the shorter the delay. Be sure to clear ice snow from the wiper blades and before using them. If they're frozen to the windshield, carefully loosen or thaw them. If your blades do become damaged, get new blades or blade inserts. I Heavy snow or icecan overload your wipers. A circuit breaker will stop them until the motor cools. Clearaway snow or iceto prevent an overload. You control the windshield wipers by turning the band marked WIPER. 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 cycle. If you want more cycles, hold the band on MIST longer. 2-36
