2003 PONTIAC BONNEVILLE coolant

Adding Washer Fluid
The washer fluid warning light will come on when the
ignition switch is on and the fluid container is less than
one-third full. On vehicles with the optional Driver
Information Center (DIC), a WASHER FLUID LOW
message
will be displayed and a chime will sound letting
you know to add windshield washer fluid to your
vehicle.
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.
