■Conditions for supplying current to the vehicle
The CCID (Charging Circuit Interrupting Device) is designed to pre-
vent electrical current from being supplied to the charging connec-
tor when it is not connected to the vehicle, even if the plug is
inserted into the socket.
■Indicator operation
3 indicators are used to indicate the following conditions.
Power indicator
Illuminates when electricity is
flowing to the CCID (Charging
Circuit Interrupting Device).
Charging indicator
Illuminates when charging is in
progress.
Error warning indicator
Flashes when there is an electri-
cal leakage or when a malfunc-
tion occurs in the CCID
(Charging Circuit Interrupting
Device).
■
When a malfunction occurs during charging
The indicators on the CCID (Charging Circuit Interrupting Device)
use a combination of different statuses (not illuminated, illuminated
or flashing) to inform the user of internal malfunctions.
When the error warning indicator is illuminated or flashing, temporarily
remove the plug from the socket and then reconnect it to check if the
error indicator turns off.
If the error warning indicator turns off, charging is now possible.
If it does not turn off, perform the correction procedure in the following
chart.

■“Traction Battery Cooler” (if equipped)
●When the hybrid battery (traction battery) is above a certain temperature
and the power switch is turned off, a check screen is displayed on the multi-
information display that indicates whether “Traction Battery Cooler” is imple-
mented. Approximately 5 minutes after selecting “Yes” on this screen, sys-
tem operation becomes possible.
●When charging starts, “Traction Battery Cooler” only operates if the hybrid
battery (traction battery) temperature is hot.
●The charging indicator is illuminated while “Traction Battery Cooler” is on
standby or operating.
●“Traction Battery Cooler” is implemented for a maximum of approximately
30 minutes. However, when the “Departure” time is set (P. 176) and there
is not sufficient time between the current time and the time that charging will
complete, “Traction Battery Cooler” operation time may become shorter.
●When there is a small amount of remaining charge in the hybrid battery
(traction battery), even if the hybrid battery (traction battery) is hot, “Traction
Battery Cooler” may not be implemented.
●When the following operations are performed while “Traction Battery Cooler”
is operating, the hybrid battery (traction battery) cooling operation stops.
• A door is opened
• The hood is opened
• The power switch is turned to any mode other than off
• The alarm operates (if equipped) (P. 8 7 )
• The shift position is changed to any position other than P
• The Remote Air Conditioning System is operated (P. 585)
• “Charge Now” is implemented (P. 177)
• The amount of remaining charge in the hybrid battery (traction battery) is
below a certain amount
●When the power switch is turned off, a check screen is displayed on the
multi-information display that indicates whether “Traction Battery Cooler” is
implemented. This check screen can be turned on and off in the “Meter Cus-
tomize” settings on the multi-information display (P. 260). However, when
the check screen is set to “Off”, “Traction Battery Cooler” is no longer oper-
ates.
●“Traction Battery Cooler” uses the power of the hybrid battery (traction bat-
tery) and external power source.
• While “Traction Battery Cooler” is operating, the amount of the remaining
charge of the hybrid battery (traction battery) increases and decreases in
a certain range, and does not increase as in normal charging.
• The operation of “Traction Battery Cooler” is recognized as charging by a
charger. The charger that calculates the fee according to charging time
causes a charging fee.

Charging tips
To enable the use of EV mode, we recommend systematically
charging the vehicle.
Before leaving home
In order to use EV mode, charge the hybrid battery (traction battery) at
home before leaving.
The charging schedule function ( P. 176) can be used to set the system
to automatically fully charge the hybrid battery (traction battery) before
your desired departure time. It is also possible to set the air conditioning to
make the interior in a comfortable state before your desired departure time.
At your destination
Use a public charging station to charge the hybrid battery (traction battery).
If there are no charging facilities at your destination, the hybrid battery
(traction battery) can be charged using the hybrid battery (traction battery)
charge mode. ( P. 9 7 )*
This section explains methods for using the charging function
for this vehicle and checking information related to charging.

Information related to charging can be displayed and checked on the
multi-information display.
■While charging
When any door is opened
during charging, the current
charging condition and remain-
ing time until charging is com-
plete can be checked.
■After charging is complete
After charging is complete, the
first time that the hybrid system
is started, a message detailing
the results of the charging is
displayed. Also, a message is
displayed if an operation that
stops charging is performed or
a situation where charging can-
not be performed occurs.
When a message is displayed, follow the instructions displayed on the
screen. (P. 197)
■Combination meter display during charging
If approximately 100 seconds elapse after the power switch is turned to ON
mode during charging, the power switch will automatically turn off and the dis-
play will disappear.

■Capacity reduction of the hybrid battery (traction battery)
The capacity of the hybrid battery (traction battery) will decline gradually
when the hybrid battery (traction battery) 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 bat-
tery capacity decline.
●Avoid parking the vehicle in areas with a high temperature under direct sun-
light when the hybrid battery (traction battery) is fully charged.
●Avoid accelerating and decelerating frequently and suddenly when EV driv-
ing.
●Avoid frequent driving near the top speed for EV driving. (P. 1 0 4 )
●Leave a low level of charge in the hybrid battery (traction battery) when
leaving the vehicle undriven for a long period of time.
After confirming that EV mode has switched to HV mode, turn the power
switch off.
●Use the charging schedule function as much as possible in order to fully
charge the hybrid battery (traction battery) immediately before starting off.
(P. 176)
Also, if the hybrid battery (traction battery) capacity reduces, the distance that
can be driven in EV mode decreases. However, vehicle performance does
not significantly become worse.
■When the remaining charge of the hybrid battery (traction battery) is low
after charging
In the following situations, the remaining charge of the hybrid battery (traction
battery) after charging completes may be less than normal in order to protect
the system (the EV driving range after the battery is fully charged may be
shorter).
*
●Charging is carried out when the outside temperature is low or high
●Charging is carried out immediately after high-load driving or in extreme
heat
When none of the above situations apply and there is a drastic drop in the
remaining charge of the hybrid battery (traction battery) after charging com-
pletes, have the vehicle inspected by any authorized Toyota retailer or Toyota
authorized repairer, or any reliable repairer.
*: When this occurs, even if the remaining charge display of the hybrid battery
(traction battery) shows that it is fully charged, the remaining charge rapidly
decreases faster than normal.
■When the charging amount sent to the hybrid battery (traction battery)
decreases
When the amount of power supplied by the charger is low or operation of the
“Traction Battery Heater”, etc., reduces the charging power sent to the hybrid
battery (traction battery), the charging amount sent to the hybrid battery (trac-
tion battery) may decrease.

If the charging indicator flashes
after inserting the charging con-
nector:
The charge schedule is regis-
tered (P. 176). Carry an elec-
tronic key and press the
charging connector lock switch
to unlock the charging connec-
tor.
After temporarily removing the charging connector, reinsert it within
approximately 5 seconds. (P. 168)
If the error warning indicator on the CCID (Charging Circuit Interrupting
Device) flashes during charging, check P. 130 and follow the correction
procedure.
The charging indicator will turn off when charging is completed.
■During charging
●The surface of the CCID (Charging Circuit Interrupting Device) may become
hot, but this does not indicate a malfunction. (When using Mode 2 charging
cable.)
●Depending on radio wave conditions, interference may be heard on the
radio.
●The current charging condition and the estimated time until charging will
complete can be checked on the multi-information display. (P. 159)
●During charging, the hybrid battery (traction battery) status indicator illumi-
nates and flashes, and changes according to the charging amount.
(P. 123)
■If the charging indicator flashes after connecting the charging cable

■When the charging cable remains connected to the vehicle
Even if multiple consecutive charge schedules are registered, the next
charge will not be carried out according to the charging schedule until the
charging cable is removed and reconnected after charging completes. Also,
when the hybrid battery (traction battery) is fully charged, charging according
to the charging schedule will not be carried out.
■“Climate Prep” (if equipped)
●When the air conditioning-linked setting is turned on, the air conditioning
operates until the set departure time. Therefore, the air conditioning will con-
sume electricity and charging may not complete by the set departure time.
●If the hybrid battery (traction battery) is fully charged, charging will not be
carried out, even if the charge schedule is set. However, if “Climate Prep” is
turned on, the air conditioning will operate only once when it nears the time
set in “Departure”. If this occurs, the air conditioning will consume electricity
and the remaining charge of the hybrid battery (traction battery) when
departing may be decreased.
●When the doors are unlocked, the air conditioning system does not operate.
■When charging schedules are ignored
When the following operations are performed while the charging schedule is
on standby, charging schedule is temporarily canceled and charging is
started.
●When the Remote Air Conditioning System (P. 585) is operated
●When turning “Charge Now” on (P. 184)
●When an operation that temporarily cancels charging using the charging
schedule is performed (P. 168)
■Effects of outside temperature
When the charging mode is set to “Departure”, charging schedule may be
ignored due to the outside temperature and charging may start.
■“Traction Battery Cooler” (if equipped) (P. 155)
When charging is carried out using the charging schedule, the hybrid battery
(traction battery) cooling function may operate according to the temperature
of the hybrid battery (traction battery).
●When the charging mode is set to “Start”, cooling starts at the set charging
start time.
●When the charging mode is set to “Departure”, cooling starts approximately
30 minutes before the charging start time. However, if there is no time to fin-
ish charging by the charging schedule, the hybrid battery (traction battery)
cooling time may be shortened and “Traction Battery Cooler” may not oper-
ate.
