■Charging connector locking system
● If the charging connector lock switch is operated repeatedly, the connector
locking system may not work to protect the system. In this case, wait for a
while before operating the switch again.
● The charging connector locking system does not guarantee to prevent theft
of the charging cable, and is not necessarily effective for all the situations.
■ When the charging connector cannot be inserted into the charging inlet
■ If the smart entry & start system has been deactivated in a customized
setting
The smart lid & connector locking system will also be deactivated. If the smart
entry & start system has been deactivated in a customized setting, the
charging connector can be unlocked by performing the following procedure.
Unlock the doors using the wireless remote control or door lock switch.
( P. 283, 285)
Press the charging connector lock switch.
The charging connector will unlock.
Check that the connector lock pin is not
lowered.
If the connector lock pin is lowered, the
connector lock is operating. Carry an
electronic key or unlock the doors, and
then press the charging connector lock
switch to unlock the connector lock and
check that the connector lock pin is not
lowered.

Reinstall the cover to the its original position.
This method is a temporary correction procedure for emergency use only. If
the problem persists, have the vehicle inspected by any authorized Toyota
retailer or Toyota authorized repairer, or any reliable repairer immediately.
Do not operate the emergency release lever when the charging connector
can be unlocked in the normal procedure.

NOTICE
■When inserting the charging connector
Observe the following precautions. Failure to do so may cause a malfunc-
tion in the charging connector locking system.
● Check that the charging connector is compatible with this vehicle
A charging connector of the different type or a charging connector with
damaged or deformed insertion part may not be locked.
● Do not operate the charging connector lock switch before the charging
connector is connected
● Do not apply excessive force to the charging connector after the charging
connector is inserted
When removing the charging connector, make sure to unlock the charging
connector.

Power sources that can be used
●Connect to an AC 220 V - 240 V socket with a Residual Current Cir-
cuit-Breaker (RCCB) and a circuit breaker. Use of a 13A individual
circuit is strongly recommended to ensure charging cable will oper-
ate properly.
● We strongly recommend that you use an exclusive connection from
the junction box for charging.
If you connect on a socket that is on a shared circuit, and other
electrical appliances are used on other sockets on the same circuit,
then the circuit breaker might trip.*
● Ensure that the junction box is equipped with a Residual Current
Circuit-Breaker (RCCB). If it is not, have one installed by a duly
qualified professional.
● When charging outdoors, make sure to connect to a rain-tight
socket that is certified for outdoor use.
Checking Residual Current Circuit-Breaker (RCCB) operation
before its use is recommended.
● Check whether there are any local EV-charging regulations in
place, and adhere to them.
*: For detailed information, consult an electrician.
An external power source that fulfills the following criteria is
necessary for charging this vehicle. Confirm this before
charging.
WARNING
■ Warnings for electrical faults
Make sure to observe the precautions in this Owner’s Manual when
charging the vehicle.
Failure to use a power source that fulfills the requirements, or failure to
observe regulations while charging could lead to an accident, possibly
resulting in death or serious injury.

■The charging environment
For safe charging, the following charging equipment and settings are recom-
mended.
●Rain-tight socket
When charging outdoors, connect the plug to a rain-tight socket, and ensure
that the plug remains waterproof while the plug is connected.
●Dedicated circuit
• To reduce the risk of fire, connect only to an at least 13A branch circuit
with an over-current protection.
• To reduce the risk of electric shock when working with the plug, connect
to a socket that has a Residual Current Circuit-Breaker (RCCB) installed.
●Remote switch
Allows the electricity from the socket to be interrupted by operating a switch,
thus allowing safe removal and insertion of the plug on rainy days.
■When your circuit breaker trips during charging
The upper limit of the charging current can be changed in the “Vehicle Set-
tings” settings on the multi-information display.
Press or of the meter control switches to select (“Vehicle
Settings”) in the screen, and then press .
Press or of the meter control switches to select “Charge Settings”,
and then press .
The “Charge Settings” screen will display.
Press or of the meter control switches to select “Charge Current”,
and then press .
The “Charge Current” screen will display.
Press or of the meter control switches to select “8A”, and then
press .
The maximum charging current during charging will be restricted to 8A.
*
If the breaker still trips while charging, even after changing the upper limit of
the charging current, check if the connected power source meets the speci-
fied charging conditions. (P. 149)
*: Restricting the charging current will lengthen the charging time.

WARNING
■Power sources precautions
Observe the following precautions.
If you do not follow them, fire, electrical shock and/or damages may occur,
possibly resulting in death or serious injury.
● Connect to an AC 220 V - 240 V socket with a Residual Current Circuit-
Breaker (RCCB) and supplied by a circuit breaker in line with local regula-
tions. Use of an individual circuit provi ded with at least 13A is strongly rec-
ommended.
● Use of a block heater socket which fails to meet the requirements is pro-
hibited for charging.
● Make sure to connect the charging connector and charging inlet directly.
Do not connect a converting adaptor or extension cord between the
charging connector and charging inlet.
● Do not connect the charging cable to a
multi-socket adaptor, multi-plugs, or
conversion plug.
● Connecting the charging cable to an
extension cord is strictly prohibited. The
extension cord may overheat and does
not contain a Residual Current Circuit-
Breaker (RCCB).
The leakage detection function of the
CCID (Charging Circuit Interrupting
Device) may not operate correctly.
● Do not connect to a power strip.

Charging methods
◆Charging from an external power source (P. 165)
This is a charging method used when charging from an AC socket
(220 V-240 V) with the charging cable equipped to the vehicle or
charging at a public charging station.
The charging start time (or departure time) and day can be set to carry
out charging using the charging schedule at the desired date and time.
(P. 176)
◆Using the hybrid battery (traction battery) charge mode
(P. 9 9 )
The plug-in hybrid system can be switched to hybrid battery (trac-
tion battery) charge mode to charge the hybrid battery (traction bat-
tery) using electricity generated by gasoline engine operation.
The maximum charge amount in the hybrid battery (traction battery)
charge mode is approximately 80% of the fully charged capacity for the
charging from an external power source.
◆Solar charging system (if equipped) (P. 188)
In certain conditions, when the vehicle is parked, the hybrid battery
(traction battery) can be charged by using electricity generated by
the solar panel equipped to the roof of the vehicle.
The maximum charge amount of the solar charging system is approxi-
mately 90% of the fully charged capacity for the charging from an exter-
nal power source. (This does not mean the battery can be fully charged
in one day.)
The following methods can be used to charge the hybrid battery
(traction battery).
