Be sure to check with your Toy-
ota dealer for precautionary
measures or special instructions
regarding installation of a mobile
two-way radio system.
High voltage parts and cables
on the battery electric vehicles
emit approximately the same
amount of electromagnetic
waves as the conventional gas-
oline powered vehicles or home
electronic appliances despite of
their electromagnetic shielding.
Unwanted noise may occur in
the reception of the mobile two-
way radio.
The vehicle is equipped with
sophisticated computers that will
record certain data, such as:
• Engine speed/ Electric motor speed (traction motor speed)
• Accelerator status
• Brake status
• Vehicle speed
• Operation status of the driving assist systems
• Images from the cameras Your vehicle is equipped with
cameras. Contact your Toyota
dealer for the location of
recording cameras.
The recorded data varies according to the vehicle grade
level and options with which it is
equipped.
These computers do not record
conversations or sounds, and
only record images outside of
the vehicle in certain situations.

Data Transmission
Your vehicle may transmit the data
recorded in these computers to
Toyota without notification to you.
Data usage
Toyota may use the data recorded
in this computer to diagnose mal-
functions, conduct research and
development, and improve quality.
Toyota will not disclose the
recorded data to a third party
except:
• With the consen t of the vehicle
owner or with the consent of the
lessee if the vehicle is leased
• In response to an official request by the police, a court of law or a
government agency
• For use by Toyota in a lawsuit
• For research purposes where the data is not tied to a specific vehi-
cle or vehicle owner
 Recorded image information
can be erased by your Toyota
dealer.
The image recording function can
be disabled. However, if the func-
tion is disabled, data from when the
system operates will not be avail-
able.

●A person inside the vehicle opens
a door or hood, or unlocks the
vehicle using an inside lock but-
ton.
●The 12-volt battery is recharged or
replaced when the vehicle is
locked. (P.543)
■Alarm-operated door lock
In the following cases, depending
on the situation, th e door may auto-
matically lock to p revent improper
entry into the vehicle:
●When a person remaining in the
vehicle unlocks the door and the
alarm is activated.
●While the alarm is activated, a
person remaining in the vehicle
unlocks the door.
●When recharging or replacing the
12-volt battery.
NOTICE
■To ensure the system oper-
ates correctly
Do not modify or remove the sys-
tem. If modified or removed, the
proper operation of the system
cannot be guaranteed.

Electric Vehicle system features
Battery electric vehicles are considerably different from con-
ventional vehicles.
They use electricity charged in a traction battery, to drive th e
electric motor. Since battery electric vehicles are driven using
electricity, they do not emit any emissions such as CO
2 (Car-
bon Dioxide) and NOx (Nitrogen Oxides). Battery electric
vehicles are environmentally friendly vehicles.

Electric Vehicle system
Provides electricity to various vehicle systems such as the SRS airbags,
headlights, wipers, etc.
*: AWD models only
■When braking (regenera-
tive braking)
The electric motor (traction
motor) charges the traction bat-
tery.
The driving range can be
extended by actively using this
regenerative braking to store
electricity in the traction battery.
The battery electric vehicle is
driven using electricity, which is
received from an external power
source and stored in the traction
battery. Not only public charging
stations, but also household out-
lets can be used for charging.
Procedures are different from
refueling a conventional vehi-
cle. Therefore, make sure to
read the following thoroughly.
 Charging equipment ( P.85)
 AC charging cable ( P. 8 7 )
 Power sources that can be
used ( P.102)
 Things to know before
charging ( P.102)
 How to charge your vehicle
( P.105, 113)
 When charging cannot be
performed normally ( P.133)■Regenerative braking
In the following situ ations, kinetic
energy is converted to electric
energy and deceler ation force can
be obtained in con junction with the
recharging of the traction battery.
●The accelerator pedal is released
while driving with the shift position
in D.
●The brake pedal is depressed
while driving with the shift position
in D.
■Charging the 12-volt battery
The 12-volt battery is charged from
the traction battery when the EV
system is operated or while the trac-
tion battery is being charged.
If the vehicle has not been used for
a long time, the 12- volt battery may
become low due to self-discharge. If
this occurs, follow the correct proce-
dures. ( P.541)
■When not using t he vehicle for
an extended period of time
●When the vehicle will not be used
for an extended period of time,
charge the traction battery once a
month.
This protects the traction battery
from extreme voltage decline due
to self discharging.
●When the vehicle will not be used
for an extended period of time, the
12-volt battery will be charged
from the traction battery to reduce
the risk of the 12- volt battery dis-
charged. In this c ase, the cooling
fan may operate, however it is not
a malfunction.
●To p r e v e n t t h e 1 2 - v o l t b a t t e r y f r o m
being discharged, do not leave the
charging port lid open or the
charging cable connected to the
vehicle.

742-1. Electric vehicle system
Owners Manual_USA_M42C01_en
■Charging the traction battery
Be sure to maintain the traction bat-
tery charge level suitable for your
driving needs.
If the traction battery fully dis-
charges, the vehicle cannot be
driven at all. When the battery
becomes low, charge it as soon as
possible.
■If the traction battery becomes
low
●If the traction battery becomes
low, the traction battery charge
warning light comes on or flashes
and a message will be displayed
on the multi-information display.
(  P.515)
●If the traction batte ry is completely
discharged, the EV system cannot
be started and dri ving will not be
possible. When the traction bat-
tery becomes low, charge it as
soon as possible.
■Sounds and vibrations specific
to an battery electric vehicle
Because there is no engine sound
or vibration, it is easy to mistake the
battery electric vehi cle for being off
when it is actually still running, as
indicated by the “READY” indicator
being illuminated. F or safety, make
sure to always shift the shift position
to P and apply the parking brake
when parked.
Before and after the EV system is
started, the following sounds and
vibrations may occur. However,
these sounds and/o r vibrations are
not signs of malfunctions:
●The brake system operation
sound may be heard from the
front of the vehicle when the
driver’s door is opened.
●Motor sounds may be heard from
the motor compartment or lug-
gage compartment.
●Electrical relay sounds may be
heard from the motor compart-
ment when the EV system starts or stops.
●Relay operating sounds such as a
snap or soft clank will be emitted
from the traction b
attery in the fol-
lowing situations:
• When the EV system is started or stopped
• When charging starts or com-
pletes
• When the vehicle is driven the first time after the traction battery has
been charged using DC charging
●Sounds may be heard due to
regenerative braking when the
brake pedal is depressed or as
the accelerator pedal is released.
●Cooling fan operating sounds
from the radiator.
●The operation sound of the air
conditioning system (air condition-
ing compressor, blower motor).
■Maintenance, repair, recycling,
and disposal
Contact your Toyota dealer regard-
ing maintenance, repair, recycling
and disposal. Do n ot dispose of the
vehicle yourself.
A sound which changes in
accordance with the driving
speed, will be played in order to
warn people nearby of the vehi-
cle’s approach. This sound may
be heard inside the vehicle. The
sound will stop when the vehicle
speed exceeds approximately
23 mph (37 km/h).
■Acoustic Vehicle Alerting Sys-
tem
In the following cases, the Acoustic
Vehicle Alerting System may be dif-
ficult for surrounding people to hear.

Electric Vehicle system precautions
Be careful of the high voltage components (nominal voltage
at 355.2 V), such as the traction battery, electricity supply
unit, orange colored high voltage cables, and electric motor,
as well as high temperature components such as the cooling
radiator, which are provided on the battery electric vehicle.
For the high voltage components, warning labels are pro-
vided on them. Read them when they need to be handled.
