7-2. Steps to take in an emergency
● 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.
■ 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 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
(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 support, ter-
minals, and other battery-related
parts.
● Do not allow children near the 12-volt
battery.
■ After recharging the 12-volt battery
Have the 12-volt battery inspected at
your Lexus dealer as soon as possible.
If the 12-volt battery is deteriorating, con-
tinued use may cause the 12-volt battery
to emit a malodorous gas, which may be
detrimental to the health of passengers.
■ When replacing the 12-volt battery
● When the vent plug and indicator are
close to the hold down bracket, the 12-
volt battery fluid (sulfuric acid) may
leak.
● For information regarding 12-volt bat-
tery replacement, contact your Lexus
dealer.
● After replacing, securely attach the
exhaust hose and exhaust hole plug to
the exhaust hole of the replaced 12-
volt battery. If not properly installed,
gases (hydrogen) may leak into the
vehicle interior, and there is the possi-
ble danger of the gas igniting and
exploding.
■ When disconnecting the 12-volt bat-
tery
Do not disconnect the negative (-) termi-
nal on the body side. The disconnected
negative (-) terminal may touch the posi-
tive (+) terminal, which may cause a short
and result in death or serious injury.
■ When connecting jumper cables
Make sure to connect jumper cables to
the specified terminals and connecting
point. Failure to do so may adversely
affect the electronic devices or damage
to them.
