82 UNDERSTANDING THE FEATURES OF YOUR VEHICLE Rain Sensitive Wiper System - If Equipped The rain sensitive wiper system provides you with the convenience of automatically detecting moisture on your windshield and turning on the wipers at the appropriate speed. The Rain Sensor is located above the rear view mirror and reacts to any moisture present in the area of the sensor. To activate the rain sensitive wiper system, turn the front wiper control lever to AUTO. When you turn the lever to AUTO, the wipers will operate a single wipe cycle. The wipers will also cycle once when you start the vehicle if the lever was left in AUTO. There are five AUTO positions on the lever to allow you to select system sensitivity that best suits you. The lowest position (closest to OFF) is the least sensitive to rain and the highest position is the most sensitive. If you select a low sensitivity position on the control lever, the system will be slower to react to rain and wipe only after some rain accumulates on the windshield. If you select a high sensitivity position, the system will be very quick to react to rain drops and will wipe more often. If it is raining steadily, the wipers will wipe continuously regardless of what sensitivity the lever is. If the rain is heavy, the wipers will operate in high speed. Every time you move the lever to a higher sensitivity, the wipers will immediately operate a single wipe cycle.
