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

The ignition must be turned to the ON/RUN or ACC/ACCESSORY position to use the windshield wipers.

Move the lever to the following positions:

(Mist): Hold the lever in this position for continuous wiping cycles.

(Off):  Turns the wipers off.

(Intermittent):  For a delayed wiping cycle. Turn the band forward or rearward for more frequent or less frequent wipes. The frequency of wipes also depends on the vehicle speed. As the vehicle speed increases, so does the wiper rate.

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

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

Never use the wipers on dry glass, as this could damage the wiper blade inserts and scratch the glass.

Be sure to clear ice and snow from the wiper blades before using them. If the blades are frozen to the windshield, carefully loosen or thaw them. If they become damaged, get new blades or blade inserts.

Heavy snow or ice can overload the wipers. A circuit breaker stops them until the motor cools. Clear away snow or ice to prevent an overload.
