WARNING
■When removing the 12-volt bat-tery terminals
Always remove the negative (-) termi-
nal first. If the positive (+) terminal contacts any metal in the surrounding area when the positive (+) terminal is
removed, a spark may occur, leading to a fire in addition to electrical shocks and death or serious injury.
■Avoiding 12-volt battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flam-mable gas that may be emitted from
the 12-volt battery:
●Make sure each jumper cable is connected to the correct terminal
and that it is not unintentionally in contact with any other than the intended terminal.
●Do not allow the other end of the jumper cable connected to the “+”
terminal to come into contact with any other parts or metal surfaces in the area, such as brackets or
unpainted metal.
●Do not allow the + and - clamps of
the jumper cables to come into con- tact with each other.
●Do not smoke, use matches, ciga-rette lighters or allow open flame near the 12-volt battery.
■12-volt battery precautions
The 12-volt battery contains poison- ous and corrosive acidic electrolyte,
while related parts contain lead and lead compounds. Observe the follow-ing precautions when handling the
12-volt battery:
●When working with the 12-volt bat- tery, always wear safety glasses
and take care not to allow any bat- tery fluids (acid) to come into con-tact with skin, clothing or the vehicle
body.
●Do not lean over the 12-volt battery.
●In the event that battery fluid (acid) comes into contact with the skin or
eyes, immediately wash the affected area with water and seek medical attention.
Place a wet sponge or cloth over the affected area until medical attention can be received.
●Always wash your hands after han-dling the 12-volt battery and other
battery-related parts.
●Do not allow children near the 12-
volt battery.
■When replacing the 12-volt bat-
tery
●When the vent plug is close to the hold down clamp, the battery fluid
(acid) may leak.
