Windshield Wipers You control the windshield wipers by turning the band with the wiper symbol on it. For steady wiping at low speed, turn the band to the LOW position. For high-speed wiping, turn the band further, to HIGH. To stop the wipers, move the band to OFF. Remember that damaged wiper blades may prevent you from seeing well enough to drive safely. To avoid damage, be sure to clear ice and snow from the wiper blades before using them. If they are frozen to the windshield, carefully loosen or thaw them. If your blades do become damaged, get new blades or blade inserts. Heavy snow or ice can overload your wipers. The windshield wiper motor is protected from overload by a circuit breaker and a fuse. If the motor overheats due to heavy snow, etc., the wiper will stop until the motor cools. Although the circuit is protected from electrical overload, overload due to heavy snow, etc. may cause wiper linkage damage. Always clear ice and heavy snow from the windshield before using your windshield wipers. For a single wiping cycle, turn the band to MIST. Hold it there until the wipersstart, then let go. The wipers will stop after one cycle. If you want more cycles, hold the band on MIST longer. You can set the wiper speed for a long or short delay between wipes. This canbe very useful in light rain or snow, Turn the band choose the delay time. The to closer to LOW, the shorter the delay. 2-36
