Adding Washer Fluid
Your vehicle has a low washer fluid message that
comes on when the washer fluid is low. The message is
displayed for 15 seconds at the star? of each ignition
cycle. When the LOW WASHER FLUID message
is displayed, you will need to add washer fluid to the
windshield washer fluid reservoir.
The windshield washer

vehicle on the driver's side.

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.
