Vehicle Care 10-27
If the vehicle has DOT 4 brake fluid,
as indicated on the reservoir cap,
use only new DOT 4 brake fluid
from a sealed container. It is
recommended that the brake/clutch
hydraulic system be flushed and
refilled with new DOT 4 fluid at a
regular maintenance service every
two years. SeeScheduled
Maintenance on page 11‑2 and
Recommended Fluids and
Lubricants on page 11‑6.
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 fluid 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 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
Refer to the replacement number
shown 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.
Vehicle Storage
{WARNING
Batteries have acid that can burn
you and gas that can explode.
You can be badly hurt if you are
not careful. See Jump Starting on
page 10‑70 for tips on working
around a battery without
getting hurt.
Infrequent Usage: Remove the
black, negative (−) cable from the
battery to keep the battery from
running down.
