DESCRIPTION AND OPERATION
Battery and Cables
Vehicles are equipped with a 12 volt maintenance-
free battery that contains a built-in hydrometer. The
hydrometer eye indication is as follows:
zA green dot means the battery is OK.
z A yellow dot, red dot, or when the green dot is not visible, means the battery needs to be
charged.
WARNING: 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
charging or working near a battery, always shield your face and protect your eyes. Always
provide ventilation.
WARNING: When lifting a battery, excessive pressure on the end walls could cause acid
to leak out through the vent caps, resulting in personal injury, damage to the vehicle or the
battery.
WARNING: Keep out of the reach of children. Batteries contain sulfuric acid. Avoid
contact with skin, eyes, or clothing. Also, shield your eyes when working near the battery to
protect against possible splashing of the 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.
Ford Motor Company strongly recommends that lead- acid batteries be returned to an authorized
recycling facility for disposal. SECTION 414-

Therefore, do not allow flames, sparks or lighted substances to come near the battery, always
shield your face and protect your eyes. Always provide ventilation. Failure to follow these
instructions may result in personal injury.
WARNING: To avoid accidental deployment and possible injury, the backup power supply
must be depleted before repairing or installing any front or side air bag supplemental restraint
system (SRS) components and before repairing, installing, adjusting or striking components
near the front or side air bag sensors, such as doors, instrument panel, console, door latches,
strikers, seats and hood latches. Failure to follow these procedures may result in personal

your hands on opposite corners. Failure to follow these instructions may result in personal
injury.
WARNING: Keep out of the reach of children. Batteries contain sulfuric acid. Avoid
contact with skin, eyes or clothing. Also, shield your eyes when working near the battery to
protect against possible splashing of the acid solution. In case of acid contact with the 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. Failure to follow these instructions
may result in personal injury.
