To clean the windshield, push in the end of the wiper knob. For a constant spray, keep the knob pushed in. After you release the knob, the wipers operate for two or three cycles before turning off (if wipers were off) or retruning to the interval setting selected. Do not try to clean the windshield when the washer fluid container is empty or activate the washers at any time for more than 15 seconds continuously. This could damage the washer pump system. RWARNING In freezing weather, warm up the windshield with the defroster before you use the washer fluid. If you do not do this, the washer solution may freeze on the windshield and obscure your vision. This may result in a collision, possibly injuring you and others. For information about refilling the washer fluid or replacing your windshield wiper blades, see Windshield washer fluid and wipers in the Index. 161
