Be sure to clear ice and snow from the wiper blades before using them. If they are frozen to the windshield, gently loosen or thaw them. Damaged wiper blades may not clear the windshield well, making it harder to see and drive safely. If the blades do become damaged, install new blades or blade inserts. 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. Clear away snow or ice to prevent an overload.

You control the windshield wipers by turning the band with the wiper symbol on it.

(Mist): For a single wiping cycle, turn the band to mist. Hold it there until the wipers start. Then let go. The wipers will stop after one wipe. If you want more wipe cycles, hold the band on mist longer.

(Delay): You can set the wiper speed for a long or short delay between wiping cycles. This can be very useful in light rain or snow. Turn the band to choose the delay time. The closer to the top of the lever, the shorter the delay.

(Low Speed): For steady wiping at low speed, turn the band away from you to the first solid band past the delay settings.

(High Speed): For high-speed wiping, turn the band further, to the second solid band past the delay settings.

(Off): To stop the wipers, move the band to off.

Use this lever, located on the right side of the steering wheel, to operate the windshield wipers.

(Off): Move the lever to this position to turn off the windshield wipers.

(Intermittent; Speed Sensitive Wipers): Move the lever to this position for intermittent or speed sensitive operation. When you select this position, the delay will vary depending on the vehicles speed, as well as the manually selected delay.

(Delay):  When the lever is in the intermittent position, turn the intermittent adjust band with this symbol on it up or down to set for a shorter or longer delay between wipes. 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): Move the lever up to the first setting past intermittent, for steady wiping at low speed.

(High Speed): Move the lever up to the second setting past intermittent, for wiping at high speed.

(Mist): Move the lever all the way down to this position for a single wiping cycle. Hold it there until the windshield wipers start; then let go. The windshield wipers will stop after one wiping cycle. If you want additional wiping cycles, hold the lever down longer.

Damaged wiper blades may prevent you from seeing well enough to drive safely. To avoid damage, be sure to 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 your blades do become damaged, get new blades or blade inserts.

Heavy snow or ice can overload your wiper motor. A circuit breaker will stop the motor until it cools. Clear away snow or ice to prevent an overload. 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 will turn on automatically. They will turn off 15 seconds after the wipers are turned off.
