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

Move the lever to one of the following positions:

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

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

(Delay): Use to set a delay between wipes.

(Delay/Intermittent Speed Sensitive): When the lever is in the delay position, move the intermittent adjust band to set for shorter or longer delay cycles. To the left of the adjust band are bars that indicate the frequency of the wipes. Smaller bars mean the wiper movement is less frequent. Larger bars mean the wiper movement is more frequent. During intermittent wiping mode, the delay cycle time is sensitive to vehicle speed. As the vehicle speed increases the delay cycle time will decrease and wiper movement occurs more frequently.

(Off): Turns off the windshield wipers.

(Mist): Move the lever to mist, for a single wiping cycle and then release it. The windshield wipers will stop after one wipe and the lever returns to its original position. Hold the band on mist longer for continuous wipes.

As an added safety feature, if the wipers are on for more than 15 seconds, the vehicle's headlamps will turn on automatically. They will turn off 15 seconds after the wipers are turned off.

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 damaged, install new blades or blade inserts. 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.
