Solid, stationary, unpainted metallic point away from the battery
and any moving parts as shown in the illustration

Start the engine of the sec-
ond vehicle. Increase the
engine speed slightly and
maintain at that level for
approximately 5 minutes to
recharge the 12-volt battery
of your vehicle.

Open and close any of the
doors of your vehicle with the
power switch OFF.

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

Once the vehicle’s hybrid
system has started, remove
the jumper cables in the
exact reverse order from
which they were connected.

When the engine cover

installing, reverse the step
removed.

Close the exclusive jump

starting terminal cover, and
reinstall the fuse box cover to
its original position.

Once the engine starts, have the
vehicle inspected at your Toyota
dealer as soon as possible.

■

Starting the hybrid system

when the battery is discharged

The hybrid system cannot be started

by push-starting.

■

To prevent 12-volt battery dis-

charge

●

Turn off the headlights and the

audio system while the hybrid sys-

tem is off.

●

Turn off any unnecessary electri-

cal components 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 Toyota dealer.

●

Some systems may require initial-

ization. (



P.571)

■

When removing the 12-volt bat-

tery terminals

When the 12-volt battery terminals

are removed, the information stored

in the ECU is cleared. Before

removing the 12-volt battery termi-

nals, contact your Toyota 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 discharge and the drain-

ing effects of certain electrical appli-

ances. 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 bat-

532

7-2. Steps to take in an emergency

tery recharges automatically while

the hybrid system is operating.)

■

When recharging or replacing

the 12-volt battery

●

In some cases, it may not be pos-

sible to unlock the doors using the

smart key 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 reinstall-

ing the 12-volt battery. In that

case, start the hybrid system in

the same manner as when the

electronic key does not operate

properly (



P.528). This is not a

malfunction, as the hybrid system

will start normally on the second

attempt.

●

The power switch mode is memo-

rized 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 discon-

necting 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 recon-

necting the 12-volt battery.

●

Some systems may require initial-

ization. (



P.571)

■

When replacing the 12-volt bat-

tery

●

Use a 12-volt battery that con-

forms to European regulations.

●

Use a battery that the case size is

same as the previous one (LN2),

20 hours rate capacity (20HR) is

equivalent (55Ah) or greater, and

performance rating (CCA) is

equivalent (345A) or greater.

• If the sizes differ, the 12-volt bat-

tery 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 12-volt battery may discharge

and hybrid system may not be

able to start.

●

Use a ventilation type calcium bat-

tery

●

Use a 12-volt battery with a han-

dle. If a 12-volt battery without a

handle is used, removal is more

difficult.

●

When removing the 12-volt bat-

tery:



P.463

●

After replacing, firmly attach the

following 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 battery prior to the replaced.

(Depending on the 12-volt battery

to be replace, the exhaust hole

may be plugged.)

For details, consult your Toyota
dealer.

WARNING

■

When removing the 12-volt

battery terminals

Always remove the negative (-)

terminal first. If the positive (+) ter-

minal contacts any metal in the

surrounding area when the posi-

tive (+) terminal is removed, a

spark may occur, leading to a fire

in addition to electrical shocks

and death or serious injury.

■

Avoiding 12-volt battery fires

or explosions

Observe the following precautions

to prevent accidentally igniting the

flammable gas that may be emit-

ted from the 12-volt battery:

●

Make sure each jumper cable is

connected to the correct termi-

nal and that it is not unintention-

ally in contact with any other

than the intended terminal.

●

Do not allow the other end of

the jumper cable connected to

the “+” terminal 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 poi-

sonous and corrosive acidic elec-

trolyte, while related parts contain

lead and lead compounds.

Observe the following precautions

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 bat-

tery.

●

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 sup-

port, terminals, and other bat-

tery-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 Toyota dealer

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 detrimental to the health

of passengers.

■

When replacing the 12-volt

battery

●

For information regarding 12-

volt battery replacement, con-

tact your Toyota dealer.

534

7-2. Steps to take in an emergency

WARNING

●

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

possible danger of the gas ignit-

ing and exploding.

WARNING

■

When inspecting under the

hood of your vehicle

Observe the following precau-

tions.

Failure to do so may result in seri-

ous injury such as burns.

●

If steam is seen coming from

under the hood, do not open the

hood until the steam has sub-

sided. The engine compart-

ment may be very hot.

●

After the hybrid system has

been turned off, check that the

“READY” indicator is off. When

the hybrid system is operating,

the gasoline engine may auto-

matically start, or the cooling fan

may suddenly operate even if

the gasoline engine stops. Do

not touch or approach rotating

parts such as the fan, which

may lead to fingers or clothing

(especially a tie, a scarf or a

muffler) getting caught, resulting

in serious injury.

●

Do not loosen the coolant reser-

voir caps, while the hybrid sys-

tem and radiator are hot.

High temperature steam or

coolant could spray out.

NOTICE

■

When adding coolant

Add coolant slowly after the

hybrid system has cooled down

sufficiently. Adding cool coolant to

a hot hybrid system too quickly

can cause damage to the hybrid

system.

■

To prevent damage to the

cooling system

Observe the following precau-

tions:

●

Avoid contaminating the coolant

with foreign matter (such as

sand or dust, etc.,).

●

Do not use any coolant additive.
