Exposure to radio fre-
quency signals

The Safety Connect system
installed in your vehicle is a
low-power radio transmitter and
receiver. It receives and also
sends out radio frequency (RF)
signals.
In August 1996, the Federal
Communications Commission
(FCC) adopted RF exposure
guidelines with safety levels for

mobile wireless phones. Those
guidelines are consistent with
the safety standards previously
set by the following U.S. and
international standards bodies.



ANSI (American National
Standards Institute) C95.1
[1992]



NCRP (National Council on
Radiation Protection and
Measurement) Report 86
[1986]



ICNIRP (International Com-
mission on Non-Ionizing Radi-
ation Protection) [1996]

Those standards were based on
comprehensive and periodic
evaluations of the relevant sci-
entific literature. Over 120 scien-
tists, engineers, and physicians
from universities, and govern-
ment health agencies and
industries reviewed the avail-
able body of research to
develop the ANSI Standard
(C95.1).
The design of Safety Connect
complies with the FCC guide-
lines in addition to those stan-
dards.

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.

System components

1-4. Hybrid system

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

: When the hybrid battery (traction

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



P.70)

■

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 S.

●

The brake pedal is depressed

while driving with the shift lever in

D or S.

■

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

1-4. Hybrid system

For safety and secu

rity

and you are unable to start the

hybrid system, contact your Toyota

dealer.

■

Charging the 12-volt battery



P.479

■

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 second 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 second seats,

when the hybrid system is started

or stopped.

●

Sounds from the hybrid system

may be heard when the back door

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 vents under the

second seats.

■

Maintenance, repair, recycling,

and disposal

Contact your Toyota dealer regard-

ing maintenance, repair, recycling

and disposal. Do not dispose of the

vehicle yourself.

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).

When the vehicle approaches to

predictive deceleration support

points registered in the navigation

system, the zone of Eco accelera-
tion (

) of the ECO Accelerator

Guidance (



P.99) on the

multi-information display will be

turned off to encourage the driver

to reduce excessive acceleration.

Example: 7-inch display

●

The engine braking force will be

increased according to the driving

conditions to more efficiently

charge the hybrid battery (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 information during

route guidance by the navigation

system to help ensure that the vehi-

cle efficiently uses electricity.

●

When there is a long downhill

slope along the route, the system

reduces the hybrid battery (trac-

tion battery) level before reaching

the slope to help ensure charging

capacity for regenerative braking

while traveling downhill.

●

When traffic congestion is pre-

dicted 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 battery (traction battery)

due to low battery levels.

■

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 second seat. The service

plug is used only when the vehi-

cle 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,

shift the shift lever to P, apply

the parking brake, 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.

●

If your vehicle needs to be

towed, do so with all four

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.

(

●

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 your Toyota dealer. Do

not dispose of the battery your-

self.

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.
