Riding with children
Observe the following pre-
cautions when children are
in the vehicle.
Use a child restraint system
appropriate for the child,
until the child becomes
large enough to properly
wear the vehicle’s seat belt.
 It is recommended that chil-
dren sit in the rear seats to
avoid accidental contact
with the steering wheel,
wiper switch, etc.
Use the rear door child-pro-
tector lock or the window
lock switch to avoid children
opening the door while driv-
ing or operating the power
window accidentally.
( P.171, 214)
Do not let small children
operate equipment which
may catch or pinch body
parts, such as the power
window, hood, back door,
seats, etc.
WARNING
■When children are in the vehi-
cle
Never leave children unattended
in the vehicle, and never allow
children to have or use the key.
Children may be able to start the
vehicle or shift the vehicle into
neutral. There is also a danger
that children ma y injure them-
selves by playing with the side
windows or other features of the
vehicle. In addition, heat build-up
or extremely cold temperatures
inside the vehicle can be fatal to
children.

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.

■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.

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.
