The windshield wiper controls are located on the multifunction lever. They are controlled by turning the band with this symbol.

The windshield wipers work in all ignition positions, except off. This includes the Retained Access Power mode. See Retained Accessory Power (RAP) .

Move the band to one of the following positions:

(Mist): Move the band to mist, for a single wiping cycle and then release it. The wipers will stop after one wipe. Hold the band in this position for continuous wiping cycles.

(Delay): For a delayed wiping cycle. Turn the band to set the length of the delay between wipes. The closer to the top of the lever, the shorter the delay.

(Low Speed): For slow, steady wiping cycles, turn the band away from you to the first solid position past the delay settings.

(High Speed): For rapid wiping cycles, turn the band to the second solid position past the delay settings.

(Off): Turns off the wipers.

Clear snow and ice from the wiper blades before using them. If the blades are frozen to the windshield, gently loosen or thaw them. If they become worn or damaged, get new blades or blade inserts.
