Brakes; Brake Fluid - Buick 2007 Rainier Owner's Manual

Adding Washer Fluid
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 your washer fluid tank and
other parts of the washer system. Also,
water does not clean as well as washer fluid.
•
Fill your washer fluid tank only
three-quarters full when it is very cold.
This allows for expansion if freezing occurs,
which could damage the tank if it is
completely full.
•
Do not use engine coolant (antifreeze) in
your windshield washer. It can damage your
washer system and paint.

Open the cap with the
washer symbol on it.
Add washer fluid
until the tank is full. See
Engine Compartment
Overview on page 366
for reservoir location.

Brakes

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. If it is, you should have your
brake system fixed, since a leak means that
sooner or later your brakes will not work well, or
will not work at all.
Your brake master
cylinder reservoir is
filled with DOT-3 brake
fluid. See Engine
Compartment Overview
on page 366 for the
location of the reservoir.
