CHANGING THE 12V
BATTERY
WARNINGS
Batteries normally produce
explosive gases which can cause
personal injury. Therefore, do not
allow flames, sparks or lighted
substances to come near the battery.
When working near the battery,
always shield your face and protect
your eyes. Always provide proper
ventilation.
When lifting a plastic-cased
battery, excessive pressure on
the end walls could cause acid to flow
through the vent caps, resulting in
personal injury and/or damage to the
vehicle or battery. Lift the battery with
a battery carrier or with your hands on
opposite corners.
Keep batteries out of reach of
children. Batteries contain
sulfuric acid. Avoid contact with skin,
eyes or clothing. Shield your eyes
when working near the battery to
protect against possible splashing of
acid solution. In case of acid contact
with skin or eyes, flush immediately
with water for a minimum of 15
minutes and get prompt medical
attention. If acid is swallowed, call a
physician immediately.
Battery posts, terminals and
related accessories contain lead
and lead compounds. Wash hands
after handling.
Maintenance
Your vehicle is equipped with a
Motorcraft® maintenance-free
battery which normally does not
require additional water during its life
of service.
Note: If your battery has a
cover/shield, make sure it is reinstalled
after the battery has been cleaned or
replaced.
For longer, trouble-free operation,
keep the top of the battery clean and
dry. Also, make certain the battery
cables are always tightly fastened to
the battery terminals.
If you see any corrosion on the battery
or terminals, remove the cables from
the terminals and clean with a wire
brush. You can neutralize the acid with
a solution of baking soda and water.
It is recommended that the negative
battery cable terminal be
disconnected from the battery if you
plan to store your vehicle for an
extended period of time.
To ensure proper operation of the
battery management system (BMS),
any electrical devices that are added
to the vehicle should not have their
ground connection made directly at
the negative battery post. A
connection at the negative battery
post can cause inaccurate
measurements of the battery
condition and potential incorrect
system operation.
