Owners Manual_USA_M42C01_en
■AC charging (P.105)
This is a charging method used
when charging from an AC out-
let with the AC charging cable or
charging that uses AC charger.
By setting charging schedule, it is
also possible to charge at the
desired date and time. ( P. 1 1 8 )
■DC charging ( P.113)
This is a charging method that
uses a DC charger that com-
plies with SAE J 1772. The trac-
tion battery can be charged in a
shorter time than AC charging.
SAE is an abbreviation for an
industrial standard issued by the
Society of Automotive Engi-
neers.
This vehicle is equipped with
several functions that are linked
with charging.
■My Room Mode ( P.129)
When the charging cable is con-
nected to the vehicle, electrical
components such as the air con-
ditioning system and audio sys-
WARNING
●Do not connect to a power strip.
●Use of a block heater for
charging is prohibited.
●Make sure to connect the
charging connector and AC
charging inlet directly. Do not
connect a converting adaptor or
extension cord between the
charging connector and AC
charging inlet.

tem can be used by the power
supply from an external power
source
*.
*: Depending on the situation, elec-
tricity of the traction battery may
be consumed.
■Traction battery heater
When the outside temperature
is low and the charging cable is
connected to the vehicle, this
function automatically warms
the traction battery until it
reaches or exceeds a certain
temperature.
 The operation of this function
is stopped automatically when
the charging cable is discon-
nected or if the charging cable
is left connected to the vehicle
for approximately 3 days.
 When the charging schedule
is used ( P.118), this func-
tion will operate according to
the schedule settings.
■Traction battery warming
control
This control operates after the
charging cable remains con-
nected to the vehicle for approx-
imately 3 days and the traction
battery heater automatically
stops. It automatically insulates
the traction battery in extremely
low temperatures.
 This control stops 31 days
after the charging cable is
connected, even if it is still
connected to the vehicle. 
When this control operates,
charging schedule settings
are ignored and charging
starts immediately.
■Traction battery cooler
When the traction battery is hot
and the AC charging cable is
connected to the vehicle, this
function cools the traction bat-
tery to protect it.
The function may operate when
continuously driving at high
speeds such as driving on high-
ways or freeways, or during DC
charging.
■Using My Room Mode during
DC charging
 P.130
■Traction battery heater
●Traction battery heater may oper-
ate when charging is not being
performed.
●When Traction battery heater is
operating, the charging indicator
will illuminate.
●When Traction battery heater is
operating during charging, the
charging may take longer than
normal.
●The remaining charge of the trac-
tion battery declines when the
traction battery hea ter operates, it
might be necessary to recharge
the traction battery again in order
to supplement the remaining
charge.
■Traction battery cooler
●For AC charging: Traction battery
cooler settings can be changed on
the multi-information display.
(  P.100)
●The AC charging indicator will illu-

●Avoid frequent DC charging
Also, if the capacit y of the traction
battery capacity reduces, the dis-
tance that can be driven decreases.
However, vehicle performance does
not significantly become worse.
■When the remaining charge of
the traction battery is low after
charging
In the following situations, the
remaining charge of the traction bat-
tery after charging completes may
be less than normal in order to pro-
tect the traction bat tery (the driving
range after the battery is fully
charged may be shorter).
*
●Charging is perf ormed when the
outside temperature is low or high
●Charging is perf ormed immedi-
ately after high-l oad driving or in
extreme heat
In any other situati on, if the remain-
ing charge of the traction battery is
significantly lower than normal after
charging completes, have the vehi-
cle inspected by your Toyota dealer.
*: When this occurs, even if the remaining charge display of the
traction battery 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
battery, the charging amount sent to
the traction battery may decrease.
■Certification

■Charging time may increase
In the following situ ations, charging
time may become longer than nor-
mal:
●In very hot or very cold tempera-
tures.
●When the traction battery
becomes hot, such as immedi-
ately after high-load driving.
●The vehicle is consuming a lot of
electricity, for e xample, when the
