charging completes may be less than
normal in order to protect the traction battery (the driving range after the bat-
tery is fully charged may be shorter).*
●Charging is performed when the out- side temperature is low or high
●Charging is performed immediately after high-load driving or in extreme
heat
In any other situation, if the remaining
charge of the traction battery is signifi-
cantly lower than normal after charging
completes, have the vehicle inspected
by any authorized Toyota retailer or
Toyota authorized repairer, or any reli-
able repairer.
*: When this occurs, even if the remain-
ing charge display of the traction bat-
tery shows that it is fully charged, the
remaining charge rapidly decreases
faster than normal.
■When the charging amount sent to the 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 traction bat-
tery, the charging amount sent to the traction battery may decrease.
■Charging time may increase

may become longer than normal:
●In very hot or very cold temperatures.
●When the traction battery becomes hot, such as immediately after high-
load driving.
●The vehicle is consuming a lot of elec-
tricity, for example, when the head- lights are on, etc.
●When using “My Room Mode”. ( P.145)
●There is a power outage during charging.
●There is an interruption in the electri-cal supply.
●There is a drop in the voltage of exter-
nal 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.

■To make sure that the charging
schedule function operates cor- rectly
Check the following items.
●Adjust the clock to the correct time ( P.178)
●The calendar is set to the correct date ( P.178)
●Check that the power switch is turned off
●After registering the charging sched-ule, connect the AC charging connec-
tor
The charging start time is determined
based on the charging schedule at the
time that the AC charging connector
was connected.
●Connect the AC charging connector
before the start time
When the charging mode is set to
“Start”, if you connect the AC charging
connector after the set start time, the
next charging schedule will be refer-
enced.
When the charging mode is “Start-Stop”,
if you connect the AC charging connec-
tor after the start time, charging will start
immediately and charging will be per-
formed until the stop time.
●After connecting the AC charging con- nector, check that the charging indica-tor of the charging port flashes
( P. 9 7 )
●Do not use an socket that has a power
cut off function (including a timer func- tion)
Use an socket that constantly supplies
electricity. For sockets where the power
is cut off due to a timer function, etc.,
charging may not be carried out accord-
ing to plan if the power is cut off during
the set time.
■When the AC charging connector remains connected to the vehicle
●When the charging mode is set to “Start”, even if multiple consecutive
charging schedules are registered, the next charge will not be carried out according to the charging schedule
until the AC charging connector is removed and reconnected after charging completes. Also, when the
traction battery is fully charged, charging according to the charging schedule will not be carried out.
●If the charging stop time is reached before the traction battery is fully
charged and the charging mode is set to “Start-Stop”, the nearest charging schedule after the stop time is
updated as the next charging sched- ule, and charging is repeated until the battery is fully charged.
