Adding Washer Fluid
When the windshield washer uid is low, a low washer
uid light may appear on the instrument panel cluster.
SeeLow Washer Fluid Warning Light on page 3-45
for more information.
In addition, if your vehicle has a Driver Information
Center (DIC), the LOW WASHER FLUID message will
display when the uid level is low. SeeDIC Warnings
and Messages on page 3-56for more information.
Open the cap with the
washer symbol on it.
Add washer uid until the
tank is full. SeeEngine
Compartment Overview
on page 5-12for reservoir
location.Notice:When using concentrated washer uid, follow
the manufacturer’s instructions for adding water.
Do not mix water with ready-to-use washer uid.
Water can cause the solution to freeze and
damage your washer uid tank and other parts
of the washer system. Also, water does not clean
as well as washer uid.
Fill the washer uid tank only three-quarters
full when it is very cold. This allows for uid
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.
