Windshield Washer Fluid; Adding Washer Fluid - GMC Yukon Owner's Manual

Windshield Washer Fluid

What to Use
When windshield washer fluid needs to be added, be
sure to read the manufacturer's instructions before use.
Use a fluid that has sufficient protection against freezing
in an area where the temperature may fall below
freezing.

Adding Washer Fluid

The 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 6 16 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 the 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
the windshield washer. It can damage the
vehicle's windshield washer system and
paint.
