Open and close any of the door of
your vehicle with the engine switch
<power switch> off.

Maintain the engine speed of the
second vehicle and start the engine
<hybrid system> of your vehicle by
turning the engine switch <power
switch> to IGNITION ON mode
<ON mode>.

Once the vehicle’s engine <hybrid
system> has started, remove the
jumper cables in the exact reverse
order from which they were con-
nected.

Close the exclusive jump starting
terminal cover, and reinstall the fuse
box cover and engine cover to its
original position.

Once the engine <hybrid system> starts,

have the vehicle inspected at any autho-

rized Lexus retailer or Lexus authorized

repairer, or any reliable repairer as soon as

possible.

Starting the engine <hybrid system>

when the 12-volt battery is discharged

The engine <hybrid system> cannot be

started by push-starting.

To prevent 12-volt battery discharge

Turn off the headlights and the audio sys-

tem while the engine <hybrid system> is

stopped.

Turn off any unnecessary electrical com-

ponents when the vehicle is running at a

low speed for an extended period, such

as in heavy traffic.

When the 12-volt battery is removed or

discharged

Information stored in the ECU is cleared.

When the 12-volt battery is depleted,

have the vehicle inspected at any autho-

rized Lexus retailer or Lexus authorized

repairer.

Some systems may require initialization.

(



P.508)

When removing the 12-volt battery ter-

minals

When the 12-volt battery terminals are

removed, the information stored in the

ECU is cleared. Before removing the 12-

volt battery terminals, contact any autho-

rized Lexus retailer or Lexus authorized

repairer.

Charging the 12-volt battery

The electricity stored in the 12-volt battery

will discharge gradually even when the

vehicle is not in use, due to natural dis-

charge and the draining effects of certain

electrical appliances. If the vehicle is left for

a long time, the 12-volt battery may dis-

charge, and the engine <hybrid system>

may be unable to start. (The 12-volt battery

recharges automatically during driving.)

When recharging or replacing the 12-

volt battery

In some cases, it may not be possible to

unlock the doors using the smart entry &

start system when the 12-volt battery is

discharged. Use the wireless remote

control or the mechanical key to lock or

unlock the doors.

The engine <hybrid system> may not start

on the first attempt after the 12-volt bat-

tery has recharged but will start normally

after the second attempt. This is not a

malfunction.

The engine switch <power switch> mode

is memorized by the vehicle. When the

12-volt battery is reconnected, the system

will return to the mode it was in before

the 12-volt battery was discharged.

Before disconnecting the 12-volt battery,

turn the engine switch <power switch> off.

If you are unsure what mode the engine

switch <power switch> was in before the

12-volt battery discharged, be especially

careful when reconnecting the 12-volt

battery.

If the 12-volt battery discharges, it may

not be possible to shift the shift position to

472

7-2. Steps to take in an emergency

other positions. In this case, the vehicle

cannot be towed without lifting both rear

wheels because the rear wheels will be

locked. (



P.436)

When replacing the 12-volt battery

Use a Central Degassing type 12-volt

battery (European Regulations).

LC500: Use a 12-volt battery that the

case size is same as the previous one

(LN4), 20 hour rate capacity (20HR) is

equivalent (80Ah) or greater, and per-

formance rating (CCA) is equivalent

(685A) or greater.

LC500h: 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.)

For details, consult any authorized Lexus
retailer or Lexus authorized repairer.

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.

WARNING

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.395), 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,

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 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.
