Driver Controls WINDSHIELD WIPER/WASHER CONTROLS Rotate the windshield wiper control to the desired interval, low or high speed position. The ignition must be in the ACC or RUN position to operate the windshield wiper. The bars of varying length are for intermittent wipers. When in this position rotate the control upward for fast intervals and downward for slow intervals. Push the control on the end of the stalk to activate washer. Push and hold for a longer wash cycle. The washer will automatically shut off after ten seconds of continuous use. Speed dependent wipers When the windshield wiper control is set on the intermittent settings, speed-sensitive front wipers automatically adjust as the vehicle's speed changes. Windshield wiper blades Check the wiper blades for wear at least twice a year or when they seem less effective. Substances such as tree sap and some hot wax treatments used by commercial car washes reduce the effectiveness of wiper blades. Checking the wiper blades If the wiper blades do not wipe properly, clean both the windshield and wiper blades using undiluted windshield wiper solution or a mild detergent. Rinse thoroughly with clean water. To avoid damaging the blades, do not use fuel, kerosene, paint thinner or other solvents. 54
