The windshield wiper control is located on the multifunction lever on the left side of the steering wheel.

Turn the band with on it to the following positions:

(Mist): For a single wiping cycle, hold the band on mist until the wipers start, then let go. The wipers will stop after one wipe. If more wipes are needed, hold the band on mist longer.

Delay: Turn the band to adjust the delay time between wipes. The closer to the top of the lever, the shorter the delay.

(Low Speed): For steady wiping at low speed.

(High Speed): For steady wiping at high speed.

(Off): Turns the wipers off.

When driving during the day and the wipers are activated, the head lamps automatically turn on after completing eight wipe cycles.

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 the blades become damaged, get new blades or blade inserts.
