Checking Brake Fluid
Apply the brake pedal several times with the
ignition off. Then clean one of the reservoir caps
and the area around the cap, and remove it.
The fluid level should be
even with the bottom
ring of the filler opening.
If it is low, add enough
fluid to fill the reservoir
to the proper level.
What to Add
Use the proper fluid listed in the Maintenance
Schedule. Use new brake fluid from a sealed
container only.
Always clean the brake fluid reservoir cap and the
area around the cap before removing it. This
helps keep dirt from entering the reservoir.
{
CAUTION:
With the wrong kind of fluid in the brake
system, the brakes may not work well.
This could cause a crash. Always use the
proper brake fluid.
Notice:
•
Using the wrong fluid can badly damage
brake system parts. For example, just a few
drops of mineral-based oil, such as engine
oil, in the brake system can damage brake
system parts so badly that they will have to
be replaced. Do not let someone put in the
wrong kind of fluid, and do not use DOT-5
silicone brake fluid.
•
If you spill brake fluid on your vehicle’s
painted surfaces, the paint finish can be
damaged. Be careful not to spill brake fluid
on your vehicle. If you do, wash it off
immediately. See Washing Your Vehicle
on page 270.
