For safety, inspect the charging cable on a routine basis.

Inspecting and maintaining the charging cable

WARNING

■

Routine inspection
Check the following points regularly.
Failure to do so may cause an unexpected accident, resulting in death or
serious injury.

●

The charging cable, plug, charging connector, CCID (Charging Circuit
Interrupting Device) etc. have not been damaged

●

The outlet has not been damaged

●

The plug can be securely inserted into the outlet

●

The plug does not get extremely hot during use

●

The tip of the plug has not been deformed

●

The plug is not dirtied by dust etc.

Remove the plug from the outlet before inspecting it. If any abnormalities
are found in the charging cable as a result of the inspection, immediately
stop use and consult your Toyota dealer.

■

Maintaining the charging cable
When the charging cable is dirty, first remove the dirt with a hard, wringed
cloth, and then wipe the cable with a dry cloth.
However, never wash it with water. If the charging cable is washed with
water, fire or electric shock may occur during charging, possibly resulting in
death or serious injury.

■

When not using the charging cable for a long time
Remove the plug from the outlet. Dust could accumulate on the plug or in
the outlet, possibly causing overheating which could lead to a fire.
Also, keep the cable in a place free from moisture.

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 recommended.

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 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.

●

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 branch 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 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. 131)

*

: 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 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 local 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 adapter, 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).

●

Do not connect to a power strip.

Charging methods

◆

Charging from an external power source (

P. 146)

This is a charging method used when charging from an AC outlet
(120 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 timer at the desired date and time. (

P. 157)

◆

Using the hybrid battery (traction 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 (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.

The time required to charge the hybrid battery (traction battery) differs
according to the charging voltage 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. 132)

*

2

: The time required for charging to complete depends on conditions such as

the remaining charge of the hybrid battery (traction battery) and the outside
temperature.

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 than 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 the vehicle being
left unused for a long period of time.

●

The maximum charging current is set to 8A through the “Vehicle Settings”
settings. (

P. 132)

●

When the “Traction Battery Heater” operates.

●

When the “Traction Battery Cooler” is operated before charging. (

P. 136)

●

When the plug generates heat due to a loose outlet connection etc.

■

Using a DC Charger
DC Chargers cannot be used with this vehicle.

This vehicle is equipped with several 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 function automatically warms the hybrid
battery (traction battery) until it reaches or exceeds a certain 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 timer is used (P. 157), this function will

operate according to the timer settings.
