■

Starting the hybrid system when the

12-volt battery is discharged

The 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 hybrid system is off.

●

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 your Lexus

dealer.

●

Some systems may require initialization.

(



P.527)

■

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 your

Lexus dealer.

■

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 hybrid system may be

unable to start. (The 12-volt battery

recharges automatically while the hybrid

system is operating.)

■

When recharging or replacing the

12-volt battery

●

In some cases, it may not be possible to

unlock the doors using the smart access

system with push-button start when the

12-volt battery is discharged. Use the

wireless remote control or the mechani-

cal key to lock or unlock the doors.

●

The hybrid system may not start on the

first attempt after the 12-volt battery has

recharged but will start normally after the

second attempt. This is not a malfunction.

●

The 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 power switch

off.

If you are unsure what mode the power

switch was in before the 12-volt battery

discharged, be especially careful when

reconnecting the 12-volt battery.

486

7-2. Steps to take in an emergency

LEXUS LS500h Owner's Manual

●

If the 12-volt battery discharges, it may

not be possible to shift the shift position to

other positions. In this case, the vehicle

cannnot be towed without lifting both

rear wheels because the rear wheels will

be locked.

■

When replacing the 12-volt battery

●

Use a Central Degassing type 12-volt

battery (European Regulations).

●

Use a 12-volt battery with the same case

size as the previous 12-volt battery and an

equivalent 20 hour rate capacity (20HR)

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 the hybrid system

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 replacing, firmly attach the follow-

ing items to the exhaust hole of the

12-volt battery.

• Use the exhaust hose that was attached

to the 12-volt battery before replacing

and confirm that it is firmly connected to

the hole section of the vehicle.

• Use the exhaust hole plug included with

the 12-volt battery replaced or the one

installed on the 12-volt battery prior to

the replacement. (Depending on the

12-volt battery to be replaced, the

exhaust hole may be plugged.)

For details, consult your Lexus dealer.

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.

■

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 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 replacing the 12-volt battery

●

When the vent plug and indicator are

close to the hold down clamp, the bat-

tery 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.

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.
