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.

■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.
Charging

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.

●In the wind or the rain
Also, as the Acoustic Vehicle Alert-
ing System is installed on the front
of the vehicle, it may be more diffi-
cult to hear from the rear of the vehi-
cle compared to the front.

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.

■Electromagnetic waves
●High-voltage parts and cables on
the battery electric vehicles incor-
porate electro-magnetic shield-
ing, and the refore emit
approximately the same amount
of electromagnetic waves as con-
ventional gasoli ne-powered vehi-
cles or home electronic
appliances.
●Your vehicle may cause sound
interference in so me third party-
produced radio parts.
■Traction battery (Lithium-ion
battery)
The traction batte ry has a limited
service life.
The traction battery capacity (the
ability to store ene rgy) reduces with
time and use in the same way as
other rechargeable batteries. The
extent at which capacity reduces
changes drastically depending on
the environment (outside tempera-
ture, etc.) and us age conditions,
such as how the vehicle is driven
and how the traction battery is
charged.
This is a natural characteristic of
lithium-ion batteries, and is not a
malfunction. Also, even though the
driving range decreases when the
traction battery capacity reduces,
vehicle performance does not sig-
nificantly become worse. In order to
reduce the possibility of the capacity
reducing, follow the directions listed
on P.103, “Capacity reduction of the
traction battery”.
■Starting the EV system in an
extremely cold environment
When the traction battery is
extremely cold (below approxi-
mately -22°F [-30°C]) due to the
temperature outside of the vehicle, it
may not be possible to start the EV
system. In this case, try to start the
EV system again after the tempera-
ture of the traction battery increases
due to the outside temperature
increasing, etc.
WARNING
■High-voltage precautions
The vehicle has high voltage DC
and AC systems as well as a 12-
volt system.
DC and AC high voltage systems
are very dangerous and can
cause severe burns and electric
shock that may result in death or
serious injury.
●Never touch, disassemble,
remove, or replace the high volt-
age parts, cables (orange) or
their connectors.
●The EV 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.

WARNING
●Never try to open the service
plug access hole located under
the floor. The service plug is
used only when the vehicle is
being serviced and is subject to
high voltage.
■Road accident cautions
Observe the following precautions
to reduce the risk of death or seri-
ous injury:
●Stop the vehicle i n a safe place
to prevent subsequent acci-
dents. While depressing the
brake pedal, apply the parking
brake and shift the shift position
to P to stop the EV system.
Then, slowly release the brake
pedal.
●Do not touch the high voltage
parts, cables (orange) and con-
nectors.
●If electric wires are exposed
inside or outside your vehicle,
an electric shock may occur.
Never touch exposed electric
wires.
●Do not touch the traction battery
if liquid is leaking from or
adhered to it. If electrolyte
(Organic Carbonate-based
electrolyte) from the 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
traction battery, do not
approach the vehicle.
Even in the unlikely event that
the traction battery has been
damaged, the internal construc-
tion of the batter y will prevent a
large amount of electrolyte from
leaking out. However, if electro-
lyte leaks, vapors will be emit-
ted. These vapors are 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.
●If a fire occurs in the battery
electric vehicle, leave the vehi-
cle as soon as possible. Never
use a fire extinguisher that is
not meant for electrical fires.
Using even a small amount of
water may be dangerous.

WARNING
●If your vehicle needs to be
towed, be sure to transport the
vehicle with the front wheels
(2WD models) or four wheels
(AWD models) raised. If the
vehicle is towed with the wheels
which are connected to the
electric motor (traction motor)
contacting the ground, electric-
ity generated by the operation of
the motor may cause a fire to
occur depending on the nature
of the damage or malfunction.
(  P.507)
●Carefully inspect the ground
under the vehicle. If leaked liq-
uid (other than water from the
air conditioning) is found on the
ground, the traction battery may
have been damaged. Leave the
vehicle as soon as possible.
In addition, contact your Toyota
dealer with regard to the leak-
age found on the ground.
Even in the event of a minor
accident, the traction battery
and surrounding parts may be
damaged. In case of an acci-
dent, have the traction battery
inspected at a Toyota dealer.
■Traction battery
●Your vehicle contains a sealed
lithium-ion battery.
●Never resell, hand over or mod-
ify the traction battery. To pre-
vent accidents, traction
batteries that have been
removed from a disposed vehi-
cle are collected through your
Toyota dealer. Do not dispose of
the battery yourself. Unless the
battery is properly collected, the
following may occur, resulting in
death or serious injury:
• Do not illegally dispose of or
dump the traction battery, and it
is hazardous to the environment
or someone may touch a high
voltage part, resulting in an
electric shock.
• The traction battery is intended to be used exclusively with your
battery electric vehicle. If the
traction battery is used outside
of your vehicle or modified in
any way, accidents such as
electric shock, heat generation,
smoke generation, an explo-
sion and electrolyte leakage
may occur. When reselling or
handing over your vehicle, the
possibility of an accident is
extremely high because the per-
son receiving the vehicle may
not be aware of the dangers
from these modifications.
●If your vehicle is disposed of
without the traction 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 traction bat-
tery must be disposed of by
your Toyota dealer or a qualified
service shop. If the traction bat-
tery is not disposed of properly,
it may cause electric shock that
can result in dea th or serious
injury.
●For information about traction
battery collection locations, con-
tact information, or the recycling
process, contact your Toyota
dealer.

When a certain level of impact is
detected by the impact sensors,
the emergency shut off system turns off the EV system and
blocks the high voltage current.
If the emergency shut off system
activates, your vehicle will not
restart. To restart the EV sys-
tem, contact your Toyota dealer.
A message is automatically dis-
played when a malfunction
occurs in the EV 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. (
P.140, 522)
■If a warning light comes on, a
warning message is displayed,
or the 12-volt battery is discon-
nected
The EV system may not start.
In that case, try to start the system
again. If the “READY” indicator does
not come on, contact your Toyota
dealer.
■When the traction battery is
completely discharged
When the EV system cannot be
started due to the traction battery
being completely discharged, restart
the system after AC charging or DC
charging. When charging, it is rec-
WARNING
■Caution while driving
●Pay special attention to the area
around the vehicle. Because
there is no engine noise, pedes-
trians, people riding bicycles or
other people and vehicles in the
area may not be aware of the
vehicle starting off or approach-
ing them, so take extra care
while driving. Therefore, take
extra care while driving even if
the Acoustic Vehicle Alerting
System is active.
●If the vehicle under floor area
receives strong shock or impact
while driving, stop the vehicle in
a safe place and check around
the bottom of the vehicle. If
there is damage to the traction
battery or liquid leakage, it may
lead to a vehicle fire, etc. Do not
touch the vehicle and immedi-
ately contact your Toyota dealer.
Even if no damage can be seen
under the floor, the traction bat-
tery may be damaged. If the
vehicle received an impact
under the floor, have the traction
battery inspected at a Toyota
dealer.
■Modifications
Do not make modifications that
lower the height of the vehicle.
The traction battery in the under
floor area may come into contact
with the ground when the height
of vehicle is lowered. If the trac-
tion battery is damaged, a vehicle
fire may occur, possibly resulting
in death or serious injury.
