1082-2. Charging
■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)
When the AC charging cable is
connected to the vehicle, electri-
cal components such as the air
conditioning system or audio
system can be used using the
external power source
*.
*: The power of the hybrid battery (traction battery) may be used
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
“Charging Settings” on the multi-
information display is on.
( P.169)
 By setting charging schedule,
“Battery Heater” operates
according to the charging
Charging methods
The following methods can
be used to charge the
hybrid battery (traction bat-
tery).
Types of charging meth-
odsCharging-linked functions

1142-2. Charging
Also, if the hybrid battery (traction
battery) capacity reduces, the dis-
tance that can be driven in EV mode
or AUTO EV/HV mode decreases.
However, vehicle performance does
not significantly become worse.
■When the remaining charge of
the hybrid battery (traction bat-
tery) is low after charging
In the following situations, the
remaining charge of the hybrid bat-
tery (traction battery) after charging
completes may be less than normal
in order to protect the system (the
EV driving range after the hybrid
battery [traction battery] is fully
charged may be shorter).
*
●Charging is carried out when the
outside temperature is low or high.
●Charging is carried out immedi-
ately 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 completes, have the vehi-
cle inspected by your Toyota dealer.
*: 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 “Battery Heater”, etc., reduces
the charging power sent to the
hybrid battery (traction battery), the
charging amount sent to the hybrid
battery (traction battery) may
decrease.

the FCC Rules. Operation is subject to the following two conditions:
(1) this device may not cause harm-
ful interference, and
(2) this device must accept any
interference received, including
interference that may cause unde-
sired operation.
■Charging time may increase
In the following si tuations, charging
time may become longer than nor-
mal:
●In very hot or very cold tempera-
tures.
●When the hybrid battery (traction
battery) becomes hot, such as
immediately after high-load driv-
ing.
●The vehicle is consuming a lot of
electricity, for example, when the
headlights are on etc.
●When using “My Room Mode”.
(  P.134)
●There is a power outage during
charging.
●There is an interruption in the
electrical supply.
●There is a drop in the voltage of

long period of time.
●When the upper limit of charging
current is changed in the charging
current setting of the vehicle.
( P.119)
●When the “Battery Heater” oper-
ates. ( P.108)
●When the “Battery Cooler” is oper-
ated before charging. ( P.109)
●When the plug generates heat
due to a loose outlet connection
etc.
