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.

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

Move the lever to control the windshield wipers.

(Off): Turns off the windshield wipers.

(Intermittent; Speed Sensitive Wipers): For intermittent or speed sensitive operation. The amount of delay time varies between wiping cycles due to the delay setting selected or the speed of the vehicle. As vehicle speed is increased or decreased, the wiper interval also increases or decreases.

(Delay):  While the lever is in the intermittent position, turn the intermittent adjust band with this symbol on it up or down to select a shorter or longer delay between wiping cycles. To the left of the adjust band are bars, increasing in size from bottom to top, that indicate the frequency of the wipes. Smaller bars mean the wipers movement is less frequent. Larger bars mean the movement is more frequent.

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

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

(Mist): Move the lever all the way down for a single wiping cycle. Hold it there until the windshield wipers start; then release. The wipers stop after one wiping cycle. Hold the lever down longer, for more wipe cycles.

Clear ice and snow from the wiper blades before using them.

If the wiper blades are frozen to the windshield, carefully loosen or thaw them. If they become damaged, install new blades.

Heavy snow or ice can overload the wiper motor. A circuit breaker stops the motor until it cools. If the motor gets stuck, turn the wipers off, clear away the snow or ice, and then turn the wipers back on.

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