Charging methods
◆Charging from an external power source (→P. 136)
This is a charging method used when charging from an AC outlet
(120 V) with the charging cable equ ipped 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. 147)
◆Using the hybrid battery (tra ction battery) charge mode
(→ P. 81)
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 generat ed 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 hybr id 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. 123)
*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).

the vehicle for 3 days and “Traction Battery Heater” automatically
stops. It automatically insulates th e hybrid battery (traction battery)
in extremely low temperatures.
● This control stops 31 days after the charging cable is connected,
even if it is still co nnected to the vehicle.
● When this control operates, timer charging settings are ignored
and charging starts immediately.
■“Traction Battery Cooler”
When the hybrid battery (traction ba ttery) is hot, this function pro-
tects it by using the vehicle ai r conditioning to cool it before
charging is carried out.
When the hybrid battery (trac-
tion 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 Bat-
tery Cooler” is implemented.

■“Traction Battery Cooler”
●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 implem ented for a maximum of approximately
30 minutes. However, when the “Departure” time is set ( →P. 147) 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.

• The hood is opened
• The power switch is turned to any mode other than off
• The shift position is changed to any position other than P
• The Remote Air Conditioning System is operated ( →P. 509)
• “Charge Now” is implemented ( →P. 156, 165)
• 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. 234). 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
charging equipment. The charging equipment that calculates the fee
according to charging time causes a charging fee.
