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.

A

D

448

7-2. Steps to take in an emergency

LS500h_OM_(U)_1809

●

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.494)

■

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.

■

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.)

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.

■

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:

A
B
C

●

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.
