10-28 Vehicle Care
After work is done on the brake
hydraulic system, make sure the
level is above the MIN but not over
the MAX mark.
What to Add
Use only new DOT 3 brake fluid
from a sealed container. See
Recommended Fluids and
Lubricants on page 11‑7.
Always clean the brake 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 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.
Battery
If the vehicle is a hybrid, see the
hybrid supplement for more
information.
Refer to the replacement number
on the original battery label when
a new battery is needed. See
Engine Compartment Overview on
page 10‑6 for battery location.

DANGER
Battery posts, terminals, and
related accessories contain lead
and lead compounds, chemicals
known to the State of California
to cause cancer and reproductive
harm. Wash hands after handling.
