ises

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.

Make sure the “READY” indi-
cator comes on. If the indica-
tor light does not come on,
contact your Toyota dealer.

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

Close the exclusive jump

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

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

■

Starting the hybrid system

when the 12-volt battery is dis-

charged

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.523)

■

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-

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 the

12-volt battery has recharged but

will start normally after the second

attempt. This is not a malfunction.

●

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

482

7-2. Steps to take in an emergency

power switch was in before the

12-volt battery discharged, be

especially careful when recon-

necting the 12-volt battery.

●

The power back door must be ini-

tialized. (



P.138)

■

When replacing the 12-volt bat-

tery

●

Use a Central Degassing type

12-volt battery (European Regula-

tions).

●

Use a 12-volt battery that the case

size is same as the previous one

(LN2), 20 hour 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 the hybrid system may not be

able to start.

●

Use a 12-volt battery with a han-

dle. If a 12-volt battery without a

handle is used, removal is more

difficult.

●

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 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 (+) 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.

■

When disconnecting the

12-volt battery

Do not disconnect the negative (-)

terminal on the body side. The

disconnected negative (-) terminal

may touch the positive (+) termi-

nal, which may cause a short and

result in death or serious injury.

WARNING

■

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 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 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 deteriorat-

ing, continued use may cause the

12-volt battery to emit a malodor-

ous gas, which may be detrimen-

tal to the health of passengers.

■

When replacing the 12-volt

battery

●

When the vent plug and indica-

tor are close to the hold down

clamp, the battery fluid (sulfuric

acid) may leak.

●

For information regarding

12-volt battery replacement,

contact your Toyota 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

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 oper-

ating, the gasoline engine may

automatically start, or the cool-

ing 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 radiator cap

and the coolant reservoir caps

while the hybrid system and

radiator are hot.

High temperature steam or

coolant could spray out.

NOTICE

■

When adding engine/power

control unit 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.

Outside temperature

SAE 0W-16 is the best choice
for good fuel economy and good
starting in cold weather.
If SAE 0W-16 is not available,
SAE 0W-20 oil may be used.
However, it must be replaced
with SAE 0W-16 at the next oil
change.
Oil viscosity (0W-16 is explained
here as an example):
• The 0W in 0W-16 indicates

the characteristic of the oil
which allows cold startability.
Oils with a lower value before

the W allow for easier starting
of the engine in cold weather.

• The 16 in 0W-16 indicates the

viscosity characteristic of the
oil when the oil is at high tem-
perature. An oil with a higher
viscosity (one with a higher
value) may be better suited if
the vehicle is operated at high
speeds, or under extreme
load conditions.

How to read oil container label:
API registered mark is added to
some oil containers to help you
select the oil you should use.
