WARNING

■

Avoiding 12-volt battery fires or explosions

Observe the following precautions to prevent accidentally igniting the flammable 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 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 compounds. Observe the following precautions when han-
dling 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 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, and
other battery-related parts.

●

Do not allow children near the 12-volt battery.

■

When replacing the 12-volt battery

After replacing, securely attach the exhaust hose and exhaust hole plug to the exhaust
hole of the new 12-volt battery. If not properly installed, gases (hydrogen) may leak into
the vehicle interior, and there is the possible danger of the gas igniting and exploding.

as possible.

WARNING

After recharging the 12-volt battery, have the 12-volt battery inspected by your Lexus
