*

when the vehicle is stopped.
During start off, the electric
motor (traction motor) drives the
vehicle. At slow speeds or when

traveling down a gentle slope,
the engine is stopped

*

and the

electric motor (traction motor) is
used.
When the shift lever is in N, the
hybrid battery (traction battery)
is not being charged.

Hybrid system features

Your vehicle is a hybrid vehicle. It has characteristics different
from conventional vehicles. Be sure you are closely familiar
with the characteristics of your vehicle, and operate it with
care.

The hybrid system combines the use of a gasoline engine and
an electric motor (traction motor) according to driving condi-
tions, improving fuel efficiency and reducing exhaust emis-
sions.

: When the hybrid battery (traction

battery) requires charging or the
engine is warming up, etc., the
gasoline engine will not automati-
cally stop. (



P.81)

■

During normal driving

The gasoline engine is predomi-
nantly used. The electric motor
(traction motor) charges the
hybrid battery (traction battery)
as necessary.

■

When accelerating sharply

When the accelerator pedal is
depressed heavily, the power of
the hybrid battery (traction bat-
tery) is added to that of the gas-
oline engine via the electric
motor (traction motor).

■

When braking (regenera-
tive braking)

The wheels operate the electric
motor (traction motor) as a
power generator, and the hybrid
battery (traction battery) is
charged.

■

Regenerative braking

In the following situations, kinetic

energy is converted to electric

energy and deceleration force can

be obtained in conjunction with the

recharging of the hybrid battery

(traction battery).

●

The accelerator pedal is released

while driving with the shift lever in

D or B.

●

The brake pedal is depressed

while driving with the shift lever in

D or B.

■

EV indicator

The EV indicator comes on when

the vehicle is driven using only the

electric motor (traction motor) or the

gasoline engine is stopped.

■

Conditions in which the gaso-

line engine may not stop

The gasoline engine starts and

stops automatically. However, it may

not stop automatically in the follow-

ing conditions:

●

During gasoline engine warm-up

●

During hybrid battery (traction bat-

tery) charging

●

When the temperature of the

hybrid battery (traction battery) is

high or low

●

When the heater is switched on

Depending on the circumstances,

the gasoline engine may also not

stop automatically in other situa-

tions.

■

Charging the hybrid battery

(traction battery)

As the gasoline engine charges the

hybrid battery (traction battery), the

battery does not need to be charged

from an outside source. However, if

the vehicle is left parked for a long

time the hybrid battery (traction bat-

tery) will slowly discharge. For this

reason, be sure to drive the vehicle

at least once every few months for

at least 30 minutes or 10 miles (16

km). If the hybrid battery (traction

battery) becomes fully discharged

and you are unable to start the

hybrid system, contact your Toyota

dealer.

■

Charging the 12-volt battery



P.499

82

1-4. Hybrid system

■

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 right

seat.

■

Maintenance, repair, recycling,

and disposal

Contact your Toyota dealer regard-

ing maintenance, repair, recycling

and disposal. Do not dispose of the

vehicle yourself.

■

Customization

Some functions can be customized.

(



P.528)

When driving with the gasoline
engine stopped, a sound, which
changes in accordance with the
driving speed, will be played in
order to warn people nearby of
the vehicle’s approach. The
sound will stop when the vehicle
speed exceeds approximately
22 mph (35 km/h).

■

Vehicle proximity notification

system

In the following cases, the vehicle

proximity notification system may be

difficult for surrounding people to

hear.

●

In very noisy areas

●

■

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 (



P.465)

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.] when the vehi-

cle is on a level surface. This value

may vary when the vehicle is on a

slope. Add extra fuel when the vehi-

cle is inclined.)

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.

■

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.

●

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.

For safety and secu

rity

WARNING

●

If your vehicle needs to be

towed, do so with the front

wheels raised. If the wheels

connected to the electric motor

(traction motor) are on the

ground when towing, the motor

may continue to generate elec-

tricity. This may cause a fire.

(



P.457)

●

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.

●

Nickel-Metal hydride battery: If

a fluid leak occurs, do not touch

the fluid as it may be strong

alkaline electrolyte from the

hybrid battery (traction battery).

If it comes into contact with your

skin or eyes, wash it off immedi-

ately with a large amount of

water or, if possible, boric acid

solution. Seek immediate medi-

cal attention.

●

Lithium-ion battery: Do not

touch the battery if liquid is leak-

ing 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.

●

Lithium-ion battery: If electrolyte

is leaking from the hybrid bat-

tery (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.

●

Lithium-ion battery: 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)

●

Lithium-ion battery: 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.

86

1-4. Hybrid system

There is an air intake vent under

the right side of the rear seat for
the purpose of cooling the
hybrid battery (traction battery).
If the vent becomes blocked, the
hybrid battery may overheat,
charging/discharging of the
hybrid battery (traction battery)
may become limited.

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

■

Hybrid battery (traction bat-

tery) air intake vent

Do not carry large amounts of

water such as water cooler bottles

in the vehicle. If water spills onto

the hybrid battery (traction bat-

tery), the battery may be dam-

aged. Have the vehicle inspected

by your Toyota dealer.

For safety and secu

rity

When a certain level of impact is
detected by the impact sensor,
the emergency shut off system
blocks the high voltage current
and stops the fuel pump to mini-
mize the risk of electrocution
and fuel leakage. If the emer-
gency shut off system activates,
your vehicle will not restart. To
restart the hybrid system, con-
tact your Toyota dealer.

A message is automatically dis-
played when a malfunction
occurs in the hybrid system or
an improper operation is
attempted.
If a warning message is shown
on the multi-information display,
read the message and follow the
instructions.
