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.

Adding Washer Fluid

5-28
Your vehicle has a low
washer fluid light that lets
you know when to add
washer fluid.
The windshield washer
reservoir is located in the
engine compartment
on the driver's side of the
vehicle.
Open the cap with the washer symbol on it. Add washer
fluid until the tank is full.
Notice:
•
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 parts of
the washer system. Also, water doesn't clean as
well as washer fluid.
•
Fill your washer fluid tank only three-quarters full
when it's very cold. This allows for expansion if
freezing occurs, which could damage the tank if
it is completely full.
•
Don't use engine coolant (antifreeze) in your
windshield washer. It can damage your washer
system and paint.
