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 your Toyota dealer imme-
diately.
Do not operate the emergency release lever when the charging connector
can be unlocked in the normal procedure.

●Do not insert hand into the connector
lock portion.
A hand may be caught in the connector
lock pin, resulting in an injury.
● Be careful not to touch the charging port
lid lock portion.
When the connector lock operates, the

NOTICE
■When locking 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 vehic le
A charging connector of the different type or a charging connec tor with
damaged or deformed insertion part may not be locked.
● Do not operate the charging connector lock switch before the charging
connector is connected
● Operate the charging connector lock switch after firmly inserting the
charging connector into the charging inlet
● Do not apply excessive force to the charging connector when the charging
connector is locked
When removing the charging connector, make sure to unlock the charging
connector.

2-2. Charging
Power sources that can be used
●Connect to an AC 120 V outlet (NEMA 5-15R) with a Ground-Fault
Circuit-Interrupter (GFCI) and a circuit breaker. Use of a 15A indi-
vidual circuit is strongly recommended to ensure charging cable will
operate properly.
● When charging outdoors, make sure to connect to a weatherproof
outlet that is certified for outdoor use.
Checking Ground-Fault Circuit-Interrupter (GFCI) operation before
its use is r ecommended.
NEMA 5-15R outlet
The illustration is an example
shown for demonstration pur-
poses, and may differ from the
actual configuration.
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 whe n
charging the vehicle.
Failure to use a power source that fulfills the requirements, o r 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.
●Weatherproof outlet
When charging outdoors, connect the plug to a weatherproof outlet, 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 15A br anch circuit
with an over-current protection in accordance with the National Electric
Code, ANSI/NFPA 70.
• To reduce the risk of electric shock when working with the plug, connect to a outlet with a Ground-Fault Circuit-Interrupter (GFCI) or that has an
Earth Leakage Circuit Breaker installed.
■ 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 Sett ings”,
and then press .
The “Charge Settings” screen will display.
Press or of the meter control switches to select “Charge Curr ent”,
and then press .
The “Charge Current” screen will display.
Press or of the meter control switches to select “8A”, and th en
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. 132)
*: Restricting the charging current will lengthen the charging ti me.

WARNING
■Power sources precautions
Observe the following precautions.
If you do not follow them, fire, electrical shock or damage may occur, possi-
bly resulting in death or serious injury.
● Connect to an AC 120 V outlet (NEMA 5-15R) with a Ground-Fault Circuit-
Interrupter (GFCI) and supplied by a circuit breaker per your l ocal code.
Use of a 15A individual circuit is strongly recommended.
● Use of a block heater for charging is prohibited.
● 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-outlet adaptor, multi-plugs, or con-
version plug.
● Connecting the charging cable to an
extension cord is strictly prohibited. The
extension cord may overheat and does
not contain a Ground-Fault Circuit-Inter-
rupter (GFCI).
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. 147)
This is a charging method used when charging from an AC outlet
(120 V) with the charging cable equipped to the vehicle or char ging
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 an d time.
( P. 158)
◆Using the hybrid battery (tr action battery) charge mode
( P. 89)
The plug-in hybrid system can be switched to hybrid battery (trac-
tion battery) charge mode to charge the hybrid battery (tractio n bat-
tery) using electric ity generated by gas oline 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.
The time required to charge the hybrid battery (traction battery) differs
according to the charging vol tage and charging current.
*1: This is the maximum value. Furthermore, the upper limit of the charging
current can be changed in the “Vehicle Settings” settings. ( P. 1 3 3 )
*2: The time required for charging to complete depends on conditions such as
the remaining charge of the hybrid battery (traction battery), the outside
temperature and specifications of a charger (charging station).
The following methods can be used to charge the hybrid battery
(traction battery).

■Charging time may increase
In the following situations, charging time may become longer th an normal:
● In very hot or very cold temperatures.
● The vehicle is consuming a lot of electricity, for example, when the head
light switch is on etc.
● There is a power outage during charging.
● There is an interruption in the electrical supply.
● There is a drop in the voltage of external power source.
● The charge in the 12-volt battery is low, for example due to th e vehicle being
left unused for a long period of time.
● The maximum charging current is set to 8A through the “Vehicle Settings”
settings. ( P. 133)
● When the “Traction Battery Heater” operates.
● When the “Traction Battery Cooler” is operated before charging. (P. 137)
● When the plug generates heat due to a loose outlet connection e tc.
■ Using a DC Charger
DC Chargers cannot be used with this vehicle.
This vehicle is equipped with sev eral functions that are linked with
charging.
■“Traction Battery Heater”
When the outside temperature is low and the charging cable is con-
nected to the vehicle, this funct ion automatically warms the hybrid
battery (traction battery) until it reaches or exceeds a certai n tem-
perature.
● When the charging cable is removed from the vehicle or remains
connected to the vehicle for approximately 3 days, the system
automatically stops.
● When the charging schedule is used ( P. 158), this function will
operate according to t he charging schedule.
