Windshield wipers off If the lever is in the 0 position and you move it upwards, the wipers will sweep one stroke at a time for as long as you hold the lever up. Intermittent wiper function With the lever in this position, you can set the wiper interval by twisting the control ring 1 upward to increase wiper speed or downward to decrease the speed. Headlight washer (certain models) When the lever is pulled to wash the windshield, high pressure jets mounted in the bumper will spray the headlights. To conserve washer fluid in driving conditions where the windshield washers are used frequently, the headlights will only be washed once for every five times the windshield is washed within a 10-minute period. A short pull on the lever will wash the windshield only. When approximately 1 US quart (1 liter) remains in the washer fluid reservoir, the headlights will not be washed when the lever is pulled to conserve washer fluid for the windshield. CAUTION Use ample washer fluid when washing the windshield. The windshield should be thoroughly wet when the wipers are in operation. Before using the wipers, ice and snow should be removed from the windshield. Be sure the wiper blades are not frozen in place. Rain sensor (option) The rain sensor automatically regulates wiper speed according to the amount of water on the windshield. The sensitivity of the sensor can be adjusted by twisting ring 1 up (the wipers will sweep the windshield more frequently) or down (the wipers will sweep the windshield less frequently). Activating the rain sensor Turn the ignition key to at least position I and put the windshield wiper lever in position 0. Press button 2. An LED in the button will light up to indicate that the rain sensor is active. Deactivating the rain sensor Press button 2.
