WARNING
■When removing the 12-volt battery
terminals
Always remove the negative (-) terminal 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 addi-tion to electrical shocks and death or
serious injury.
■Avoiding 12-volt battery fires or explosions
Observe the following precautions to prevent accidentally igniting the flamma-
ble gas that may be emitted from the 12- volt battery:
●Make sure each jumper cable is con-nected 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 “+” ter-
minal 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 contact with each other.
●Do not smoke, use matches, cigarette
lighters or allow open flame near the 12-volt battery.
●If the 12-volt battery fluid level is exces-sively low ( P.327), do not use the
12-volt battery.
■12-volt battery precautions
The 12-volt battery contains poisonous and corrosive acidic electrolyte, while related parts contain lead and lead com-
pounds. Observe the following precau- tions when handling the 12-volt battery:
●When working with the 12-volt battery, always wear safety glasses and take
care not to allow any 12-volt battery fluids (acid) to come into contact with
skin, clothing or the vehicle body.
●Do not lean over the 12-volt battery.
●In the event that 12-volt battery fluid 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 handling the 12-volt battery support, terminals,

WARNING
■After recharging the 12-volt battery
Have the 12-volt battery inspected at any authorized Lexus retailer or Lexus authorized repairer, or any reliable
repairer as soon as possible. If the 12-volt battery is deteriorating, continued use may cause the 12-volt battery to emit a
malodorous gas, which may be detri- mental to the health of passengers.
■When exchanging the 12-volt battery
After exchanging, securely attach the exhaust hose and exhaust hole plug to
the exhaust hole of the exchanged 12- volt battery. If not properly installed, gases (hydrogen) may leak into the vehi-
cle interior, and there is the possible dan- ger of the gas igniting and exploding.
NOTICE
■When handling jumper cables
When connecting the jumper cables, ensure that they do not become entan-gled in the cooling fan or engine drive
belt.
■To prevent damaging the vehicle
The exclusive jump starting terminal is to be used when charging the 12-volt bat-tery from another vehicle in an emer-
gency. It cannot be used to jump start another vehicle.
