What to Add
Use only new DOT-4 brake fluid
from a sealed container. It is
recommended that the brake
hydraulic system be flushed and
refilled with new DOT-4 fluid
at a regular maintenance service
every two years. See Additional
Required Services on page 11-6
and Recommended Fluids and
Lubricants on page 11-12.
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 hydraulic system,
the brakes might not work well.
This could cause a crash.
Always use the proper brake fluid.
Notice:
• Using the wrong fluid can badly
damage brake hydraulic system
parts. For example, just a few
drops of mineral-based oil,
such as engine oil, in the brake
hydraulic system can damage
brake hydraulic system parts so
badly that they will have to be
replaced. Do not let someone
put in the wrong kind of fluid.
• If brake fluid is spilled on the
vehicle’s painted surfaces, the
paint finish can be damaged.
Be careful not to spill brake
fluid on the vehicle. If you do,
wash it off immediately. See
Exterior Cleaning on page 9-76.
Brake Wear
This vehicle has disc brakes.
Notice: Continuing to drive
with worn-out brake pads could
result in costly brake repair.
Front disc brake pads have built-in
brake pad wear indicators that
make a high-pitched warning sound
when the brake pads are worn
and new pads are needed.
The sound can come and go or be
heard all the time the vehicle is
moving, except when applying the
brake pedal firmly.
{ CAUTION
The brake wear warning sound
means that soon the brakes will
not work well. That could lead to
an accident. When the brake wear
warning sound is heard, have the
vehicle serviced.
