The windshield wiper lever is located on the right side of the steering column.

Move the lever to one of the following positions:

(Mist): Move to mist for a single wiping cycle and then release it. The lever will return to its original position. Hold the lever in this position for continuous wiping cycles.

(Off): Turns off the wipers.

(Delay):  For a delayed wiping cycle. Turn the delay adjustment band to set the length of the delay.

(Delay Adjustment): Use this band to set the length of the delay between wipes when using the delay feature. The closer the band is moved toward mist, the longer the delay. The windshield wiper lever must be in delay for this feature to work.

(Low Speed): For slow, steady wiping cycles.

(High Speed): For rapid wiping cycles.

If the windshield wipers are in use for about six seconds while you are driving, the exterior lamps will come on automatically if the exterior lamp control is in AUTO. See Wiper Activated Headlamps for more information.

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

Heavy snow or ice can overload the wiper motor. A circuit breaker will stop the motor until it cools down.

For STS-V, the vehicle is equipped with a feature that disables the wiper system when the hood is open and the vehicle is stopped. Opening the hood will automatically park the wipers if they are not parked.
