Windshield Washer Fluid; Adding Washer Fluid - Buick Lucerne 2010 Owner's Manual

Windshield Washer Fluid

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

Adding Washer Fluid

Open the cap with the
washer symbol on it.
Add washer fluid until the
tank is full. See Engine
Compartment Overview
on page 6 14 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.
