7-2. Steps to take in an emergency

When the battery is removed or dis-

charged

Side window open/close function linked

to door operation does not operate.

When closing the side window, slowly

close the side window while pushing the
upper portion

of the side window

inside the soft top roof.

Information stored in the ECU is cleared.

When the battery is depleted, have the

vehicle inspected at any authorized

Lexus retailer or Lexus authorized

repairer.

Some systems may require initialization.

P.446)

When removing the battery terminals

When the battery terminals are removed,

the information stored in the ECU is

cleared. Before removing the battery termi-

nals, contact any authorized Lexus retailer

or Lexus authorized repairer.

Charging the battery

The electricity stored in the battery will dis-

charge gradually even when the vehicle is

not in use, due to natural discharge and the

draining effects of certain electrical appli-

ances. If the vehicle is left for a long time,

the battery may discharge, and the engine

may be unable to start. (The battery

recharges automatically during driving.)

When recharging or replacing the bat-

tery

Immediately after replacing the battery,

fully open or close the soft top roof, as the

luggage cover may be half-opened.

In some cases, it may not be possible to

unlock the doors using the smart entry &

start system when the battery is dis-

charged. Use the wireless remote control

or the mechanical key to lock or unlock

the doors.

The engine may not start on the first

attempt after the battery has recharged

but will start normally after the second

attempt. This is not a malfunction.

The engine switch mode is memorized by

the vehicle. When the battery is recon-

nected, the system will return to the

mode it was in before the battery was dis-

charged.

Before disconnecting the battery, turn

the engine switch off. If you are unsure

what mode the engine switch was in

before the battery discharged, be espe-

cially careful when reconnecting the bat-

tery.

If the battery discharges, it may not be

possible to shift the shift position to other

positions. In this case, the vehicle cannot

be towed without lifting both rear wheels

because the rear wheels will be locked.

(



P.384)

When replacing the battery

Use a Central Degassing type battery

(European Regulations).

Use a battery that the case size is same as

the previous one (LN4), 20 hour rate

capacity (20HR) is equivalent (80Ah) or

greater, and performance rating (CCA)

is equivalent (685A) or greater.

• If the sizes differ, the battery cannot 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 battery may dis-

charge and engine may not be able to

start.

Use a battery with a handle. If a battery

without a handle is used, removal is more

difficult.

After exchanging, firmly attach the fol-

lowing items to the exhaust hole of the

battery.

• Use the exhaust hose that was attached

to the battery before exchanging.

• Use the exhaust hole plug included with

the battery exchanged or the one

installed on the battery prior to the

exchange. (Depending on the battery to

be exchanged, the exhaust hole may be

plugged.)

WARNING

When removing the battery termi-

nals

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 battery fires or explosions

Observe the following precautions to

prevent accidentally igniting the flamma-

ble gas that may be emitted from the bat-

tery:

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

battery.

If the battery fluid level is excessively

low (



P.344), do not use the battery.

Battery precautions

The battery contains poisonous and cor-

rosive acidic electrolyte, while related

parts contain lead and lead compounds.

Observe the following precautions when

handling the battery:

When working with the 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 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.



There is a possibility to damage the
vehicle when applying a strong

WARNING

Always wash your hands after han-

dling the battery support, terminals,

and other battery-related parts.

Do not allow children near the battery.

After recharging the battery

Have the battery inspected at any autho-

rized Lexus retailer or Lexus authorized

repairer, or any reliable repairer as soon

as possible. If the battery is deteriorating,

continued use may cause the battery to

emit a malodorous gas, which may be

detrimental to the health of passengers.

When exchanging the battery

After exchanging, securely attach the

exhaust hose and exhaust hole plug to

the exhaust hole of the exchanged bat-

tery. If not properly installed, gases

(hydrogen) may leak into the vehicle

interior, and there is the possible 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 battery from

another vehicle in an emergency. It can-

not be used to jump start another vehicle.
