.
Fill the washer fluid tank only three-quarters
full when it is very cold. This allows for fluid
expansion if freezing occurs, which could
damage the tank if it is completely full.
.
Do not use engine coolant (antifreeze) in the
windshield washer. It can damage the
windshield washer system and paint.

Brake Fluid
The brake master cylinder
reservoir is filled with DOT
3 brake fluid. See Engine
Compartment Overview
on page 6‑14
for the
location of the reservoir.
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.
{
WARNING:
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.
When the brake fluid falls to a low level, the brake
warning light comes on. See Brake System Warning
Light on page 4‑31.
