• Do not make contact between battery terminal posts, or
between a post and the vehicle, through tools, jumper
leads, or other conductors, or you may be seriously
burned or electrocuted.
• Use a suitable battery carrier to transport the battery if it
must be moved. Do not carry the battery cradled in your
arms.
• Wear acid-proof rubber gloves when handling battery
cable clamps which have been exposed to acidic
battery fumes and corrosion.
• Clean acidic corrosion from battery terminal posts and
cable clamps using baking soda and water before
handling parts to avoid acid burns of skin. Rinse parts
with clean water after scrubbing off corrosion.
• Keep self, clothing, and tools clear of all moving or hot
engine parts or you may be injured or burned.
• Do not use booster cables if insulation is damaged.
• Connect clamps in the order called out in the
instructions and the tag on the cables.
• Do not allow battery clamps to touch each other when
making or breaking connections to battery.
• Do not connect cables backwards or vehicle charging
and computer systems may be damaged.
• Keep cigarettes, sparks, and open flames away from
battery at all times.
• Never attempt to jump start a frozen battery.

• Before connecting booster cable clamps, be sure that
vehicles are not touching each other.
• On vehicle with discharged battery, be sure that
parking brake is applied, ignition is OFF, and
transmission is in neutral or park before making
booster cable connections.
• Be sure that booster cables will not be in the way of fan
blades, drive belts, or other moving parts when engine
is started.
• Check electrical system polarity of vehicle with
discharged battery. If vehicle has a positive ground
system (positive battery cable is connected to chassis
or engine block), the black clamp would be connected
to the negative battery terminal first, then the red
clamp would be connected to the vehicle chassis.
