■Electromagnetic waves
●High-voltage parts and cables on the battery electric vehicles incorporate electro-magnetic shielding, and there-
fore emit approximately the same amount of electromagnetic waves as conventional gasoline-powered vehi-
cles or home electronic appliances.
●Your vehicle may cause sound inter-
ference in some third party-produced radio parts.
■Traction battery (Lithium-ion bat-tery)
The traction battery has a limited service life.
The traction battery capacity (the ability
to store energy) reduces with time and use in the same way as other recharge-able batteries. The extent at which
capacity reduces changes drastically depending on the environment (outside temperature, etc.) and usage 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 significantly become worse. In order to reduce the possibility of the
capacity reducing, follow the directions listed on P.119, “Capacity reduction of the traction battery”.
■Starting the EV system in an
extremely cold environment
When the traction battery is extremely cold (below approximately -30°C [-
22°F]) 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 tem- perature of the traction battery increases due to the outside temperature increas-
ing, etc.
■Declaration of conformity
This model conforms to hydrogen emis- sions according to regulation ECE100
(Battery electric vehicle safety).
WARNING
■High-voltage precautions
The vehicle has high voltage DC and AC systems as well as a 12-volt sys-tem.
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 voltage 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 tempera-
ture, and always obey the warning labels attached to the vehicle.

2-2. Charging
Electric Vehicle system
■While parking
For vehicles with a solar charging
system, solar charging is performed
to charge the traction battery when
the necessary conditions such as
parking are met. ( P.148)
When the traction battery is fully
charged, charging the battery via the
solar charging system is not performed.
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 condition and
approximate time remaining until
charging is complete are displayed
for a certain period of time.
The actual charging time may differ
depending on conditions such as
the remaining capacity of the trac-
tion battery, outside temperature,
and specifications of the AC/DC
charger.
The time until charging completed
may not be displayed if the
charging current to the traction bat-
tery 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 message 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 performed
occurs.
When a message is displayed, fol-
low the instructions displayed on
the screen. ( P.160)

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.
■When the remaining charge of the traction battery is low after charging
In the following situations, the remaining charge of the traction battery after

dures of the DC charger.
5 Operate the DC charger and
start the charging.
Follow the handling procedures of the DC charger to start charging.
Charging starts after a system check is
done.
6 Confirm that the charging indi-
cator on the charging port lights
up.
When the charging indicator is not lit, charging has not started.
Stop the charging in accordance to the
handling procedures of the DC charger when it is desired to interrupt the DC charging.
■Charging time may increase
 P. 1 2 0
■When the DC charging connector cannot be inserted into the DC charging inlet
 P. 1 1 0
■If a message indicating vehicle
error on the DC charger side is dis- played
Even if a message indicating vehicle
error on the DC charger side (ex. vehicle error found, vehicle error occurred, etc.) is displayed, there is no vehicle fault but
possibly a communication error between the DC charger and vehicle. In this case, there may be terminal damage (bad
contact) in the DC charging connector. If there is no error with the vehicle, contact the facility manager of the DC charger.
■During DC charging
●The current charging condition can be checked on the multi-information dis-
play.
●The actual charging time may differ
from that displayed on the DC charger during charging.
●There may be occasions the radio cannot be heard due to noise occur-rence during DC charging
●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 traction battery, the outside tem-perature, the specifications of the
charger (stand), etc.
●It is recommended to avoid frequent
DC charging to prevent a decline in the traction battery capacity.
●Quickly move from the DC charging space for other users after the DC charging is completed.
■How to set the DC charging power
You can change the DC charging power limit on the multi-information display or multimedia.
●Setting operations on multi-informa-tion display

8-2. Steps to take in an emergency
When trouble arises
order from which they were con-
nected.
10 Close the positive (+) battery
terminal cover.
Once the EV system starts, have
the vehicle inspected at any autho-
rized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer as soon as possible.
■Starting the EV system when the 12-volt battery is discharged
The EV system cannot be started by push-starting.
■To prevent 12-volt battery dis-charge
●Turn off the headlights, the air condi-tioning system, the audio system, etc.
while the EV system is off.
●Turn off any unnecessary electrical
components when the vehicle is run- ning at a low speed for an extended period, such as in heavy traffic.
■Charging the 12-volt battery
The electricity stored in the 12-volt bat- tery will discharge gradually even when the vehicle is not in use, due to natural
discharge and the draining effects of certain electrical appliances. If the vehi-cle is left for a long time, the 12-volt bat-
tery may discharge, and the EV system may be unable to start. (The 12-volt bat-tery recharges automatically while the
EV system is operating.)
■When the 12-volt battery is removed or discharged
●Information stored in the ECU is cleared. When the 12-volt battery is depleted, have the vehicle inspected
at any authorized Toyota retailer or Toyota authorized repairer, or any reli-able repairer.
●In some cases, it may not be possible to unlock the doors using the smart
entry & start system when the 12-volt
battery is discharged. Use the wire-
less remote control or the mechanical key to lock or unlock the doors.
●The EV system may not start on the first attempt after the 12-volt battery has recharged but will start normally
after the second attempt. This is not a malfunction.
●The power switch mode is memorized by the vehicle. When the 12-volt bat-tery is reconnected, the system will
return to the mode it was in before the 12-volt battery was discharged. Before disconnecting the 12-volt bat-
tery, turn the power switch off. If you are unsure what mode the power switch was in before the 12-volt
battery discharged, be especially careful when reconnecting the 12-volt battery.
●If the 12-volt battery discharges, it may not be possible to shift the shift
position to other positions. In this case, the vehicle cannot be towed without lifting both front wheels
because the front wheels will be locked.
●The power back door (if equipped) must be initialized. ( P.198)
■When replacing the 12-volt battery
●Use a 12-volt battery that conforms to European regulations.
●Use a 12-volt battery that the case size is same as the previous one (LN1), 20 hour rate capacity (20HR) is
equivalent (45Ah) or greater, and per- formance rating (CCA) is equivalent (286A) or greater.
• If the sizes differ, the 12-volt battery cannot be properly secured.• If an improper 12-volt battery is used,
battery performance may decrease and the EV system may not be able to restart.
• If the 20 hour rate capacity is low, even if the time period where the vehi-cle is not used is a short time, the 12-
volt battery may discharge and EV system may not be able to start.
