When using concentrated washer fluid,
follow the manufacturer's instructions for
adding water.
Don't mix water with ready-to-use wasner
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.
Brakes
Brake Fluid
Your brake master cylinder reservoir is here. It is filled
with DOT-3 brake fluid.
There are only two reasons why the brake fluid
level in the reservoir might go down. The first is that
the brake fluid goes down to an acceptable level
during normal brake lining wear. When new linings
are put in, the fluid level goes back up. The other
reason is that fluid is leaking out of the brake system.
