■AC charging (P.116)
This is a charging method used
when charging from an AC out-
let with the AC charging cable or
charging that use an AC char-
ger.
By setting charging schedule, it is
also possible to charge at the
desired date and time. ( P.123)
■Using the hybrid battery
(traction battery) charge
mode ( P.75)
The plug-in hybrid system can
be switched to hybrid battery
(traction battery) charge mode
to charge the hybrid battery
(traction battery) 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.136)
In certain conditions, when the vehicle is parked, the hybrid bat-
tery (traction battery) can be
charged by using electricity gen-
erated by the solar panel
equipped to the roof of the vehi-
cle.
This vehicle is equipped with
several functions that are linked
with charging.
■“My Room Mode” (
P.134)

depending on the situation.
■“Battery Heater”
When the outside temperature
is low and the AC charging
cable is connected to the vehi-
cle, this function automatically
warms the hybrid battery (trac-
tion battery) until it reaches or
exceeds a certain temperature.
“Battery Heater” will operate
when the “Battery Heater” of the

■“Battery Cooler”
●The charging indicator is illumi-
nated while “Battery Cooler” is on
standby or operating.
●“Battery Cooler” is implemented
for a maximum of approximately
30 minutes.
●When there is a small amount of
remaining charge in the hybrid
battery (traction battery), even if
the hybrid battery (traction battery)
is hot, “Battery Cooler” may not be
implemented.
●When the hybrid battery (traction
battery) is almost completely
charged, “Battery Cooler” may not
be implemented.
●When the following operations are
performed while “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
• “Charge Now” is implemented ( P.124)

the hybrid battery (traction battery)
and external power source.
• While “Battery Cooler” is operat- ing, the remaining charge of the
hybrid battery ma y not increase
the same amount as during nor-
mal charging.
• The operation of “Battery Cooler”
is recognized as charging by a
charger. The charger that calcu-
lates the fee according to charging
time causes a charging fee.
