7-2. Steps to take in an emergency

Type B

: Use a 12-volt battery that the

case size is same as the previous one

(LN3), 20 hour rate capacity (20HR) is

equivalent (70Ah) or greater, and perfor-

mance rating (CCA) is equivalent

(600A) or greater.

• If the sizes differ, the 12-volt battery can-

not be properly secured.

• If the 20 hour rate capacity is low, even if

the time period where the vehicle is not

used is a short time, the 12-volt battery

may discharge and engine <hybrid sys-

tem> may not be able to start.

●

Use a 12-volt battery with a handle. If a

12-volt battery without a handle is used,

removal is more difficult.

●

After exchanging, firmly attach the fol-

lowing items to the exhaust hole of the 12-

volt battery.

• Use the exhaust hose that was attached

to the 12-volt battery before exchanging.

• Use the exhaust hole plug included with

the 12-volt battery exchanged or the one

installed on the battery prior to the

exchange. (Depending on the 12-volt

battery to be exchanged, the exhaust

hole may be plugged.)

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.301), do not use the 12-

volt battery.

WARNING

■

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,

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 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.
