Windshield Washer Fluid
What to Use
When you need windshield washer fluid, be sure to read
the manufacturer’s 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. See Engine
Compartment Overview on page 5-12 for reservoir
location.
Adding Washer Fluid
Open the cap and add
washer fluid until the tank
is full. Make sure the
cap is secured after filling.
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.
