■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.

Electric Vehicle system
Information related to charging
is displayed and can be checked
on the multi-information display.
■While charging
When any door is opened during
charging with the power switch
off, the current charging condi-
tion and approximate time
remaining until charging is com-
plete are displayed for a certain
period of time.
The actual charging time may
differ depending on conditions
such as the remaining capacity
of the traction battery, outside
temperature, and specifications
of the AC/DC charger.
The time until charging com-
pleted may not be displayed if
the charging current to the trac-
tion battery becomes smaller
and the charging time becomes
longer.
■After charging is complete
When any door is opened with
the power switch off after
charging is complete, a mes-
sage detailing the results of the
charging is displayed for a while.
Also, a message is displayed if
an operation that stops charging
is performed or a situation
where charging cannot be per-
formed occurs.
When a message is displayed,
follow the instructions displayed
on the screen. ( P.140)Checking information
related to charging

Electric Vehicle system
Before charging, always check
the following items.
 The parking brake is applied.
( P.243)
 The power switch is turned to
OFF. ( P.231)
 Lights such as the headlights,
emergency flashers and inte-
rior lights, etc. are turned off.
If these light switches are turned
on, then these features will con-
sume electricity, and charging time
will increase.
Before charging, make sure that
each part of the AC charging
cable is in good condition.
( P.92)
■During charging
●The charging starting time may
differ depending on the state of
the vehicle, but this does not indi-
cate a malfunction.
●During charging, sounds may be
heard from near the traction bat-
tery in accordance with the opera-
tion of the air conditioning system
or “Battery Cooler” ( P.99).
●During and after charging, the motor compartment and its sur-
rounding 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 condi-
tions, 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 registered, temporarily turn off the
function or turn “ Charge Now” on.
(  P. 1 1 9 )
• When the charging schedule is set to on, charging will not start even
if the AC charging cable is con-
nected. Also, charging fee may
occur due to connection of the AC
charging cable.
■Capacity reduction of the trac-
tion battery
The capacity of the traction battery
will decline gradually when the trac-
tion battery is in use. The rate at
which it declines will differ in accor-
dance 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
temperature areas, under direct
sunlight when the traction battery
is fully charged.
●Avoid accelerating and decelerat-
ing frequently and suddenly.
●Avoid frequent d riving at high
speed.
●Use the charging schedule func-
tion as much as possible in order
to fully charged the traction bat-
tery before starting off. ( P. 1 1 8 )
NOTICE
●When charging with a charger,
follow the procedures for using
each charger.
Confirm the following
before charging
Inspecting the AC
charging cable

1042-2. Charging
Owners Manual_USA_M42C01_en
●Avoid frequent DC charging
Also, if the capacit y of the traction
battery capacity reduces, the dis-
tance that can be driven decreases.
However, vehicle performance does
not significantly become worse.
■When the remaining charge of
the traction battery is low after
charging
In the following situations, the
remaining charge of the traction bat-
tery after charging completes may
be less than normal in order to pro-
tect the traction bat tery (the driving
range after the battery is fully
charged may be shorter).
*
●Charging is perf ormed when the
outside temperature is low or high
●Charging is perf ormed immedi-
ately after high-l oad driving or in
extreme heat
In any other situati on, if the remain-
ing charge of the traction battery is
significantly lower than normal after
charging completes, have the vehi-
cle inspected by your Toyota dealer.
*: When this occurs, even if the remaining charge display of the
traction battery shows that it is
fully charged, the remaining
charge rapidly decreases faster
than normal.
■When the charging amount sent
to the traction battery
decreases
When the amount of power supplied
by the charger is low or operation of
the battery heater, etc., reduces the
charging power sent to the traction
battery, the charging amount sent to
the traction battery may decrease.

■Charging time may increase
In the following situ ations, charging
time may become longer than nor-
mal:
●In very hot or very cold tempera-
tures.
●When the traction battery
becomes hot, such as immedi-
ately after high-load driving.
●The vehicle is consuming a lot of
electricity, for e xample, when the
headlights are on, etc.
●When using “My Room Mode”.

●As the battery approaches full
charge, the charging speed will
decrease and it will take longer to
complete charging.
●The time to complete charging
may change, or charging may
stop before reaching the upper
limit of the charge capacity, due to
the remaining charge of the trac-
tion battery, the outside tempera-
ture, the specifications of the
charger (stand), etc.
●It is recommended to avoid fre-
quent DC charging to prevent a
decline in the traction battery
capacity.
