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

Open the cap with the
washer symbol on it.
Add washer fluid
until the tank is full. See
Engine Compartment
Overview on page 506
for reservoir location.
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 the washer fluid tank only
three-quarters full when it is very cold.
This allows for fluid 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
the vehicle's windshield washer system
and paint.
