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.

●

■

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.453)

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.

System components

72

1-4. Hybrid system

■

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.

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 fluid leak occurs, do not

touch the fluid as it may be

strong alkaline electrolyte from

the hybrid battery (traction bat-

tery). If it comes into contact

with your skin or eyes, wash it

off immediately with a large

amount of water or, if possible,

boric acid solution. Seek imme-

diate medical attention.

●

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.

73

1-4. Hybrid system

For safety and secu

rity

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

●

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.445)

●

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.

■

Hybrid battery (traction bat-

tery)

●

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.

• 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.

1-4. Hybrid system

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.

■

If a warning light comes on, a

warning message is displayed,

or the 12-volt battery is discon-

nected

The hybrid system may not start. In

this case, try to start the system

again. If the “READY” indicator does

not come on, contact your Toyota

dealer.

NOTICE

■

Hybrid battery (traction bat-

tery) air intake vent

●

Make sure that the air intake

vent is not blocked, such as by

a seat cover, plastic cover, or

luggage. If the vent is blocked,

charging/discharging of the

hybrid battery (traction battery)

may become limited, possibly

leading to a malfunction.

●

Clean the air intake vent regu-

larly to prevent the hybrid bat-

tery (traction battery) from

overheating.

●

Do not allow liquid or foreign

material to enter the air intake

vent as this may cause a short

circuit and damage the hybrid

battery (traction battery).

●

A filter is installed to the air

intake vent. When the filter

remains noticeably dirty even

after cleaning the air intake

vent, filter cleaning or replace-

ment is recommended. Refer to
