Brake Fluid
The brake master
cylinder reservoir is filled
with DOT-3 brake fluid.
See Engine Compartment
Overview on page 5-12
for reservoir location and
access.
There are only two reasons why the brake fluid level in
the reservoir might go down:
The brake fluid level goes down because of normal
brake lining wear. When new linings are installed,
the fluid level goes back up.
A fluid leak in the brake hydraulic system can also
cause a low fluid level. Have the brake hydraulic
system fixed, since a leak means that sooner
or later the brakes will not work well.
Do not top off the brake fluid. Adding fluid does not
correct a leak. If fluid is added when the linings are worn,
there will be too much fluid when new brake linings are
installed. Add or remove brake fluid, as necessary, only
when work is done on the brake hydraulic system.
{ CAUTION:
If too much brake fluid is added, it can spill on the
engine and burn, if the engine is hot enough. You
or others could be burned, and the vehicle could
be damaged. Add brake fluid only when work is
done on the brake hydraulic system.
If the ignition is on and the brake fluid is low, the
CHECK BRAKE FLUID message displays in the
Driver Information Center (DIC). See DIC Warnings
and Messages on page 3-79.
