Windshield Washer Fluid

What to Use
When you need windshield washer fluid, be sure to read
the manufacturer's instructions before use. If you will be
operating your vehicle 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.

The washer fluid reservoir
is located behind the front
panel on the driver's side
of the vehicle.
NOTICE:
D
When using concentrated washer fluid,
follow the manufacturer's instructions for
adding water.
D
Don't mix water with ready
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.
D
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.
D
Don't use engine coolant (antifreeze) in
your windshield washer. It can damage
your washer system and paint.
