Brake Fluid
Your brake master
cylinder reservoir is
filled with DOT-3 brake
fluid. See Engine
Compartment Overview
on page 342 for the
location of the reservoir.
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.
So, it is not a good idea to top off your brake fluid.
Adding brake fluid will not correct a leak. If you add
fluid when your linings are worn, then you will have
too much fluid when you get new brake linings. You
should add or remove brake fluid, as necessary,
only when work is done on the brake hydraulic
system.
{CAUTION:
If you have too much brake fluid, it can spill
on the engine. The fluid will burn if the
engine is hot enough. You or others could
be burned, and your vehicle could be
damaged. Add brake fluid only when work
is done on the brake hydraulic system.
If the ignition is in ON and the brake fluid is low,
the “Check Brake Fluid” message will be displayed
in the DIC. See “Check Brake Fluid Message”
under DIC Warnings and Messages on page 228.
When your brake fluid falls to a low level, your
brake warning light will come on. See Brake
System Warning Light on page 197.
