To operate the windshield wipers turn the band, located on the multifunction lever, upward or downward.

WIPER : Turn the band on the turn signal lever to control the wipers.

MIST: Turn the band toward you to MIST and then release it for a single wiping cycle. For more cycles, hold the band on MIST longer.

LO or HI (Low or High): Turn the band away from you to either LO (low speed) or to HI (high speed), depending on the wiper speed you want.

Delay: Turn the band to one of the delay positions to set the wiper speed for a long or a short delay between wipes. The closer you move it to LO, the shorter the delay.

OFF: Turn the band to OFF to turn off the wipers.

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 do become damaged, get new blades or blade inserts.

Heavy snow or ice can overload the wiper motor. A circuit breaker will stop the motor until it cools. Clear away snow or ice to prevent an overload.

Your vehicle is equipped with wiper-activated headlamps. After the windshield wipers have been on for approximately six seconds, the headlamps will automatically turn on. See Wiper Activated Headlamps for more information.
