After the 12-volt battery has dis-

charged or when the terminal

has been removed and installed

during exchange, etc.

The gasoline engine may not stop

even if the vehicle is being driven by

the hybrid battery (traction battery).

If this continues for a few days, con-

tact your Toyota dealer.

■

Sounds and vibrations specific

to a hybrid vehicle

There may be no engine sound or

vibration even though the vehicle is

able to move with the “READY” indi-

cator is illuminated. For safety, apply

the parking brake and make sure to

shift the shift lever to P when

parked.
The following sounds or vibrations

may occur when the hybrid system

is operating and are not a malfunc-

tion:

●

Motor sounds may be heard from

the engine compartment.

●

Sounds may be heard from the

hybrid battery (traction battery)

under the rear seats when the

hybrid system starts or stops.

●

Relay operating sounds such as a

snap or soft clank will be emitted

from the hybrid battery (traction

battery), under the rear seats,

when the hybrid system is started

or stopped.

●

Sounds from the hybrid system

may be heard when the trunk lid is

open.

●

Sounds may be heard from the

transmission when the gasoline

engine starts or stops, when driv-

ing at low speeds, or during idling.

●

Engine sounds may be heard

when accelerating sharply.

●

Sounds may be heard due to

regenerative braking when the

brake pedal is depressed or as

the accelerator pedal is released.

●

Vibration may be felt when the

gasoline engine starts or stops.

●

Cooling fan sounds may be heard

from the air intake vent on the side

of the lower part of the rear left

seat.

■

Predictive deceleration sup-
port



When the vehicle approaches
to predictive deceleration sup-
port points registered in the
navigation system, the “Zone
of Eco acceleration” ( ) of
the ECO Accelerator Guid-
ance (→P.104, 111) on the
multi-information display will
be turned off to encourage the
driver to reduce excessive
acceleration.

7-inch display



The engine braking force will
be increased according to the
driving conditions to more effi-
ciently charge the hybrid bat-
tery (traction battery) after the
accelerator pedal is released.

■

Predictive SOC

control

The following types of control
are performed based on data
such as road and traffic informa-
tion during route guidance by
the navigation system to help
ensure that the vehicle effi-
ciently uses electricity.



When there is a long downhill
slope along the route, the sys-
tem reduces the hybrid bat-
tery (traction battery) level
before reaching the slope to
help ensure charging capacity
for regenerative braking while
traveling downhill.



When traffic congestion is
predicted along the route, the
system helps ensure a certain
battery level before reaching
congested roads to reduce
the frequency of starting the
engine to charge the hybrid

Running out of fuel

When the vehicle has run out of fuel

and the hybrid system cannot be

started, refuel the vehicle with at

least enough gasoline to make the

low fuel level warning light (



go off. If there is only a small

amount of fuel, the hybrid system

may not be able to start. (The stan-

dard amount of fuel is about 2.0 gal.

[7.6 L, 1.7 Imp. gal.] (2WD models)

Hybrid system precautions

Take care when handling the hybrid system, as it is a high
voltage system (about 600 V at maximum) as well as contains
parts that become extremely hot when the hybrid system is
operating. Obey the warning labels attached to the vehicle.

or 1.6 gal. [6.0 L, 1.3 Imp. gal.]

(AWD models) when the vehicle is

on a level surface. This value may

vary when the vehicle is on a slope.

Add extra fuel when the vehicle is

inclined.)

■

Electromagnetic waves

●

High voltage parts and cables on

hybrid vehicles incorporate elec-

tromagnetic shielding, and there-

fore emit approximately the same

amount of electromagnetic waves

as conventional gasoline pow-

ered vehicles or home electronic

appliances.

●

Your vehicle may cause sound

interference in some third

party-produced radio parts.

■

Hybrid battery (traction battery)

The hybrid battery (traction battery)

has a limited service life. The lifes-

pan of the hybrid battery (traction

battery) can change in accordance

with driving style and driving condi-

tions.

■

Starting the hybrid system in an

extremely cold environment

When the hybrid battery (traction

battery) is extremely cold (below

approximately -22°F [-30°C]) under

the influence of the outside tem-

perature, it may not be possible to

start the hybrid system. In this case,

try to start the hybrid system again

after the temperature of the hybrid

battery increases due to the outside

temperature increasing, etc.

WARNING

■

High voltage precautions

This vehicle has high voltage DC

and AC systems as well as a

12-volt system. DC and AC high

voltage is very dangerous and

can cause severe burns and elec-

tric shock that may result in death

or serious injury.

●

Never touch, disassemble,

remove or replace the high volt-

age parts, cables or their con-

nectors.

●

The hybrid system will become

hot after starting as the system

uses high voltage. Be careful of

both the high voltage and the

high temperature, and always

obey the warning labels

attached to the vehicle.

●

Never try to open the service

plug access hole located under

the right side of the rear seat.

The service plug is used only

when the vehicle is serviced

and is subject to high voltage.

■

Road accident cautions

Observe the following precautions

to reduce the risk of death or seri-

ous injury:

●

Pull your vehicle off the road,

apply the parking brake, shift

the shift lever to P, and turn the

hybrid system off.

●

Do not touch the high voltage

parts, cables and connectors.

●

If electric wires are exposed

inside or outside your vehicle,

an electric shock may occur.

Never touch exposed electric

wires.

1-4. Hybrid system

WARNING

●

If a fire occurs in the hybrid

vehicle, leave the vehicle as

soon as possible. Never use a

fire extinguisher that is not

meant for electric fires. Using

even a small amount of water

may be dangerous.

●

If your vehicle needs to be

towed, do so with front wheels

(2WD models) or four wheels

(AWD models) raised. If the

wheels connected to the electric

motor (traction motor) are on

the ground when towing, the

motor may continue to generate

electricity.This may cause a fire.

(

P.366)

●

Carefully inspect the ground

under the vehicle. If you find

that liquid has leaked onto the

ground, the fuel system may

have been damaged. Leave the

vehicle as soon as possible.

●

Do not touch the battery if liquid

is leaking from or adhering to it.

If electrolyte (carbonic-based

organic electrolyte) from the

hybrid battery (traction battery)

comes into contact with the

eyes or skin, it could cause

blindness or skin wounds. In the

unlikely event that it comes into

contact with the eyes or skin,

wash it off immediately with a

large amount of water, and seek

immediate medical attention.

●

If electrolyte is leaking from the

hybrid battery (traction battery),

do not approach the vehicle.

Even in the unlikely event that

the hybrid battery (traction bat-

tery) is damaged, the internal

construction of the battery will

prevent a large amount of elec-

trolyte from leaking out. How-

ever, any electrolyte that does

leak out will give off a vapor.

This vapor is an irritant to skin

and eyes and could cause acute

poisoning if inhaled.

●

Do not bring burning or

high-temperature items close to

the electrolyte.

The electrolyte may ignite and

cause a fire.

■

Hybrid battery (traction bat-

tery)

●

Your vehicle contains a sealed

lithium-ion battery.

●

Never resell, hand over or mod-

ify the hybrid battery. To prevent

accidents, hybrid batteries that

have been removed from a dis-

posed vehicle are collected

through Toyota dealer. Do not

dispose of the battery yourself.

Unless the battery is properly col-

lected, the following may occur,

resulting in death or serious

injury:
• The hybrid battery may be ille-

gally disposed of or dumped,

and it is hazardous to the envi-

ronment or someone may touch

a high voltage part, resulting in

an electric shock.

1-4. Hybrid system

For safety and secu

rity

There are air intake vents under

the left side of the rear seat with
the purpose of cooling the
hybrid battery (traction battery).
If the vents are blocked, it may
interfere with the cooling of the
hybrid battery (traction battery).
If input/output of the hybrid bat-
tery (traction battery) becomes
limited and the distance that the
vehicle can be driven using the
electric motor (traction motor) is
reduced, the fuel economy may
be reduced.

WARNING

• The hybrid battery is intended to

be used exclusively with your

hybrid vehicle. If the hybrid bat-

tery is used outside of your

vehicle or modified in any way,

accidents such as electric

shock, heat generation, smoke

generation, an explosion and

electrolyte leakage may occur.

When reselling or handing over

your vehicle, the possibility of an

accident is extremely high

because the person receiving the

vehicle may not be aware of these

dangers.

●

If your vehicle is disposed of

without the hybrid battery hav-

ing been removed, there is a

danger of serious electric shock

if high voltage parts, cables and

their connectors are touched. In

the event that your vehicle must

be disposed of, the hybrid bat-

tery must be disposed of by

your Toyota dealer or a qualified

service shop. If the hybrid bat-

tery is not disposed of properly,

it may cause electric shock that

can result in death or serious

injury.

NOTICE
