rF Open the cap labeled WASHER FLUID ONLY. Add washer fluid until the tank is full. NOTICE: 0 0 0 The windshield washer fluid reservoir is located on the driver's side of the vehicle, toward the front of the engine compartment. 0 When using concentrated washer fluid, follow the manufacturer's instructions for adding water. Don't mix water with ready-to-use washer fluid. Water can cause the solution to freeze and damage your washer fluid tank and other partsof the washer system.
