Use this lever located on the right side of the steering wheel to operate the windshield wipers. The ignition must be turned to ON to operate the windshield wipers.

HI (High): Turn the lever to this position for wiping at high speed.

LO (Low): Turn the lever to this position for steady wiping at low speed.

INT (Intermittent): If equipped, turn the lever to this position to choose a delayed wiping cycle. Turn the center band on the windshield wiper lever toward LO for a longer delay or toward HI for a shorter delay. The wiper speed can only be adjusted when the lever is in the INT position.

AUTO (Automatic Wiper with Rain Sensor): If equipped, turn the lever to this position to operate the windshield wipers automatically. The ignition must be on. The rain sensor detects the amount of water on the windshield and automatically regulates the wipers. The sensitivity of the system can be adjusted by turning the center band. Keep the rain sensor, located on the windshield behind the rearview mirror, free from dust and dirt to ensure proper operation.

OFF: Turn the lever to this position to turn off the windshield wipers.

Misting Function

Move the lever toward, but not completely into, the AUTO position for a single wiping cycle. Hold it there until the windshield wipers start; then let go. The windshield wipers will stop after one wipe. If you want more wipes, hold the band toward AUTO longer.

Remember that 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 they 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.
