●For details, consult any authorized
Toyota retailer or Toyota authorized repairer, or any reliable repairer.
WARNING
■When removing the battery ter-
minals
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 battery fires or explo-sions
Observe the following precautions to
prevent accidentally igniting the flam- mable gas that may be emitted from the 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 battery.
■Battery precautions
The battery contains poisonous and
corrosive acidic electrolyte, while related parts contain lead and lead compounds. Observe the following
precautions when handling the bat- tery:
●When working with the battery, always wear safety glasses and take care not to allow any battery
fluids (acid) to come into contact with skin, clothing or the vehicle body.
●Do not lean over the battery.
●In the event that battery fluid comes into contact with the skin or eyes, immediately wash the affected area
with water and seek medical atten- tion. Place a wet sponge or cloth over the affected area until medical
attention can be received.
●Always wash your hands after han-
dling the battery support, terminals, and other battery-related parts.
●Do not allow children near the bat-tery.
■When replacing the battery
●When the vent plug and indicator are close to the hold down clamp,
the battery fluid (sulfuric acid) may leak.
●For information regarding battery replacement, contact any autho-rized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
