Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the instructions before use. If you will be operating
your vehicle in an area where the temperature may fall
below freezing, use a fluid that has sufficient protection
against freezing.
Adding Windshield Washer Fluid
Open the cap with this
symbol printed on it and
add washer fluid until
the tank is full.
Notice:
• When using concentrated washer fluid, follow
the manufacturer’s instructions for adding
water.
• Do not mix water with ready-to-use washer fluid.
Water can cause the solution to freeze and
damage your washer fluid tank and other parts
of the washer system. Also, water does not
clean as well as washer fluid.
• Fill your washer fluid tank only three-quarters
full when it is very cold. This allows for
expansion if freezing occurs, which could
damage the tank if it is completely full.
• Do not use engine coolant (antifreeze) in your
windshield washer. It can damage your washer
system and paint.
