7-2. Steps to take in an emergency

■

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 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.474)

■

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 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 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 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 battery that conforms to European

regulations.

●

Use a 12-volt battery that the case size is

same as the previous one (LN2), 20 hour

rate capacity (20HR) is equivalent

(60Ah) or greater, and performance rat-

ing (CCA) is equivalent (345A) 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 ventilation type calcium battery.

●

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 new 12-volt battery or the one

installed on the battery prior to the

replacement. (Depending on the new 12-

volt battery installed, 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:

●

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 han-

dling the 12-volt battery support, ter-

minals, and other battery-related

parts.

●

Do not allow children near the 12-volt

battery.
