12-volt battery
Provides electricity to various vehicle systems such as the SRS airbags, headlights,
wipers, etc.
*: AWD models only
■When braking (regenerative
braking)
The battery electric motor (traction
motor) charges the traction battery.
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 sock-
ets can be used for charging. Pro-
cedures are different from refueling
a conventional vehicle. Therefore,
make sure to read the following
thoroughly.
 Charging equipment (P.95)
 AC charging cable (P. 9 8 )
 Power sources that can be used
( P.112)
 Things to know before charging
( P.118)
 How to charge your vehicle
( P.121, 129)
 When charging cannot be per-
formed normally ( P.152)
■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
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 traction 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 procedures. ( P.544)
■When not using the 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 discharged. In this case, the cooling fan may operate,
however it is not a malfunction.
●To prevent the 12-volt battery from
being discharged, do not leave the charging port lid open or the charging cable connected to the vehicle.

■Charging the traction battery
Be sure to maintain the traction battery charge level suitable for your driving needs.
If the traction battery fully discharges, 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 mes-sage will be displayed on the multi-
information display. ( P.517)
●If the traction battery is completely
discharged, the EV system cannot be started and driving will not be possi-ble. When the traction battery
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 bat-tery electric vehicle for being off when it
is actually still running, as indicated by the “READY” indicator being illuminated. For 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 vibra- tions may occur. However, these sounds and/or vibrations are not signs of mal-
functions:
●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 luggage com-
partment.
●Electrical relay sounds may be heard
from the motor compartment when the EV system starts or stops.
●Relay operating sounds such as a snap or soft clank will be emitted from the traction battery in the following sit-
uations:
• When the EV system is started or stopped• When charging starts or completes
• When the vehicle is driven the first time after the traction battery has been charged using DC charging
●Sounds may be heard due to regener-ative 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 condi-tioning system (air conditioning com-pressor, blower motor).
■Maintenance, repair, recycling, and
disposal
Contact any authorized Toyota retailer or Toyota authorized repairer, or any reli-
able repairer regarding maintenance, repair, recycling and disposal. Do not dispose of the vehicle yourself.
A sound which changes in accor-
dance with the driving speed, will
be played in order to warn people
nearby of the vehicle’s approach.
This sound may be heard inside the
vehicle. The sound will stop when
the vehicle speed exceeds approxi-
mately 25 km/h (15 mph).
■Acoustic Vehicle Alerting System
In the following cases, the Acoustic Vehicle Alerting System may be difficult
for surrounding people to hear.
●In very noisy areas
●In the wind or the rain

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 serious injury:
●Stop the vehicle in a safe place to
prevent subsequent accidents. 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 connectors.
●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 blind-
ness or skin wounds. In the unlikely event that it comes into contact with the eyes or skin, wash it off immedi-
ately with a large amount of water, and seek immediate medical atten-tion.
●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 construction of the bat-
tery will prevent a large amount of electrolyte from leaking out. How-ever, if electrolyte leaks, vapors will
be emitted. These vapors are an irritant to skin and eyes and could cause acute poisoning if inhaled.
●Do not bring burning or high-tem-perature items close to the electro-
lyte. The electrolyte may ignite and cause a fire.
●If a fire occurs in the battery electric vehicle, leave the vehicle as soon as possible. Never use a fire extin-
guisher that is not meant for electri- cal fires. Using even a small amount of water may be danger-
ous.
●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) con-
tacting the ground, electricity gener- ated by the operation of the motor may cause a fire to occur depend-
ing on the nature of the damage or malfunction. ( P.509)

Electric Vehicle system
Shift the shift position to D when
stopped at a traffic light, or driving
in heavy traffic, etc. Shift the shift
position to P when parking. When
shifting the shift position to N while
driving, there is no positive effect
on electricity consumption. In the N,
the traction battery cannot be
charged. Also, when using the air
conditioning system, etc., the trac-
tion battery electricity is consumed.
( P.248)
Repeated acceleration and decel-
eration due to traffic congestion,
long waits at traffic lights, and driv-
ing on steep inclines will lead to
poor electricity consumption. In
order to avoid those situations as
much as possible, check traffic
reports before leaving. If the vehicle
is driven in traffic congestion, gently
release the brake pedal to allow the
vehicle to move forward slightly,
avoid overuse of the accelerator
pedal. Doing so can help minimize
unnecessary electricity consump-
tion.
Make sure to operate the brakes
gently and a timely manner. A
greater amount of electrical energy
can be regenerated when slowing
down.
Control and maintain the vehicle at
a constant speed. Before stopping
at a toll booth or similar, allow
plenty of time to release the accel-
erator and gently apply the brakes.
A greater amount of electrical
energy can be regenerated when
slowing down.

driving tips
Unlike the conventional vehi-
cles, the electricity consump-
tion efficiency of battery
electric vehicles will decline if
they continue driving on high-
ways (or freeways) or at high
average speeds, causing the
possible driving distance to
reduce. Therefore, if the
remaining charge of the trac-
tion battery is low, avoid rely-
ing on the displayed possible
driving distance too much as
well as driving on highways (or
freeways). Driving the vehicle
at moderate speeds, the trac-
tion battery’s electricity con-
sumption can be controlled.
The following driving tips will
contribute to reduction in the
battery consumption and
increase in the driving range.

2-2. Charging
Electric Vehicle system
Before charging, always check the
following items.
 The parking brake is applied.
( P.254)
 The power switch is turned to
OFF. ( P.243)
 Lights such as the headlights,
emergency flashers and interior
lights, etc., are turned off.
If these light switches are turned on,
then these features will consume elec-
tricity, and charging time will increase.
Before charging, make sure that
each part of the AC charging cable
is in good condition. ( P.106)
■During charging
●The charging starting time may differ
depending on the state of the vehicle, but this does not indicate a malfunc-
tion.
●During charging, sounds may be
heard from near the traction battery in accordance with the operation of the air conditioning system or “Battery
Cooler” ( P.115).
●During and after charging, the motor
compartment and its surrounding area in which the onboard traction battery charger is installed may get warm.
●The surface of the CCID (Charging Circuit Interrupting Device) may
become hot, but this does not indicate a malfunction.
●Depending on radio wave conditions,
interference may be heard on the
radio.
■When charging using a public charging facility
●When charging using a public charging facility, check the setting of the charging schedule function.
• When the charging schedule is regis- tered, temporarily turn off the function or turn “Charge Now” on. ( P.134)
• When the charging schedule is set to on, charging will not start even if the AC charging cable is connected. Also,
charging fee may occur due to con- nection of the AC charging cable.
■Capacity reduction of the traction battery
The capacity of the traction battery will decline gradually when the traction bat-tery is in use. The rate at which it
declines will differ in accordance with environmental conditions and the way in which the vehicle is used. Observing the
following can help suppress the decline in the traction battery capacity.
●Avoid parking the vehicle in high tem-perature areas, under direct sunlight when the traction battery is fully
charged.
●Avoid accelerating and decelerating
frequently and suddenly.
●Avoid frequent driving at high speed.
●Use the charging schedule function as much as possible in order to fully
charged the traction battery before starting off. ( P.134)
●Avoid frequent DC charging
Also, if the capacity of the traction bat-
tery capacity reduces, the distance that
can be driven decreases. However,
vehicle performance does not signifi-
cantly become worse.
