The windshield wipers are controlled by turning the band with the wiper symbol on it.

(Off): Turns off the windshield wipers.

(Mist): For a single wiping cycle. Hold it there until the wipers start, then let go. The wipers will stop after one cycle. If more wipes are needed, hold the band on mist longer. The wiper speed can be set for long or short delays between wipes. Turn the band to select the delay time. The farther the band is turned upward or downward, the longer or shorter the delay. For steady wiping at low speed, turn the band toward you to the first solid band below the delay settings. For high-speed wiping, turn the band farther, to the last solid band below the delay settings.

Clear ice and snow from the wiper blades before using them. If the wipers are frozen to the windshield, carefully loosen or thaw them. If they become worn or damaged, get new blades or blade inserts. For more information, see Windshield Wiper Blade Replacement .

The windshield wiper motor is protected from overload by a circuit breaker and a fuse. If the motor overheats due to heavy snow or ice the wiper will stop until the motor cools. Although the circuit is protected from electrical overload, overload due to heavy snow or ice may cause wiper linkage damage.
