BATTERY
Your vehicle may be equipped with
a Motorcraft maintenance-free
battery. If the original equipment
battery needs replacing, it may be
replaced with a low-maintenance
battery. The low-maintenance
battery normally does not require
additional water during its life of
service. However, for severe usage
or in high temperature climates,
check your battery electrolyte
level, at least every 24 months or
40,000 km (24,000 miles). Keep
the electrolyte in each cell up to
the ªlevelº indicator. Do not overfill
the battery cells.
If the electrolyte level in the
battery is low, you can add plain
tap water to the battery, as long as
you do not use hard water (water
with a high alkali content). If
possible, however, try to only fill
the battery cells with distilled
water. If the battery needs water
often, have the charging system
checked.
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 terminal(s) and
clean with a wire brush. You can
neutralize the acid with a solution
of baking soda and water. Reinstall
the cables when you are done
