What to Add
Use only new DOT 3 brake
fluid from a sealed container.
SeeRecommended Fluids and
Lubricants on page 10-7.
Always clean the brake/clutch
fluid reservoir cap and the area
around the cap before removing it.
This helps keep dirt from entering
the reservoir.
{WARNING
With the wrong kind of fluid in the
brake/clutch hydraulic system,
the brakes might not work well.
This could cause a crash. Always
use the proper brake/clutch fluid.Notice:
Using the wrong uid can
badly damage brake/clutch
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 uid.
If brake uid is spilled on the
vehicle’s painted surfaces, the
paint nish can be damaged.
Be careful not to spill brake
uid on the vehicle. If you do,
wash it off immediately.

free battery. When it is time for a
