■When the power switch is turned
off
You can check the next charging sched -
ule (“Next Event”) on the “Closing Dis -
play” screen* when “Closing Display” is

be displayed during charging.
WARNING
■Cautions while performing the
setting operation
When performing the setting opera- tion while the hybrid system is oper -
ated, ensure that the vehicle is parked
in a place with adequate ventilation. In a closed area such as a garage,
exhaust gases including harmful car -
bon monoxide (CO) may collect and
enter the vehicle. This may lead to death or a serious health hazard.
NOTICE
■While performing the setting operation
When performing the setting opera-
tion while the hybrid system is stopped, be careful that the 12-volt
battery will not be discharged.

the color and size of the arrows.
Discharging status
Charging status
When the electricity supply from the AC
charging cable is larger than the power
consumption inside the vehicle,
becomes larger. When the power con -
sumption is larger than the electricity
supply, becomes larger.
When the electricity supply and con -
sumption are balanced (when the
power balance is judged to be zero),
and are displayed as the same

■When a door is unlocked while using “My Room Mode”
The charging connector unlocks,
charging stops and “My Room Mode” stops. In order to use “My Room Mode”
again, reconnect the AC charging cable
and start “My Room Mode” ( →P.153). When using “My Room Mode” with pub -
lic charging station, operation to start
charging using the charger may be required again before starting “My Room
Mode”.
■Meter display during charging
If “My Room Mode” is not turned on for approximately 100 seconds after the
power switch is turned on during
charging, the power switch will automat- ically turn off.
■While using “My Room Mode”
Any of the follo wing may occur.
●When the remaining charge of the
hybrid battery (traction battery)
reaches the lower l imit, the air condi- tioning system automat ically turns off.
In this situation, the air conditioning
system cannot be us ed until the remaining charge of the hybrid battery
(traction battery) increases. Turn the
power switch off and use “My Room Mode” after the remaining charge of
the hybrid battery ( traction battery) is
restored.
●When the outside te mperature is low,
the heater o utput may be limited due
to the air conditioning system opera - tion being restricted.
●Warning lights and indicators such as electric power steering system warn -
ing light (yellow) and malfunction indi -
cator lamp may turn on, but this is not a malfunction.
Also, when the surrounding area is
dark, the headlight s are turned on. ( →P.332)
■When a charging schedule is regis-
tered
When “My Room Mode” starts while the charging schedule is on standby,
charging schedules are ignored and
charging starts.
■When “My Room Mode” is used while the hybrid battery (traction
battery) is fully charged
When the power switch is turned on while the hybrid battery (traction battery)
is fully charged and the charging con -
nector that supplies power is connected, “Charging Port Lid i s Open” is displayed
on the multi-informati on display. In this
case, press of th e meter control
switches to display the setting screen of “My Room Mode”, and then select “My
Room Mode”.
When “My Room Mode ” is used while the hybrid battery ( traction battery) is
fully charged, the ele ctric power of the
hybrid battery (trac tion battery) may be consumed. In this case, charging may
be performed again.
■When a message related to “My
Room Mode” is displayed
When a message is displayed on the
multi-information display while using or
attempting to start “My Room Mode”, take the following correction proce -
dures.
●“Traction battery is too low for “My
Room Mode””
There is insufficient remaining charge in
the hybrid battery ( traction battery) for
starting “My Room Mode”.
Wait until the charge of the hybrid bat-
tery (traction batter y) increases, then
start “My Room Mode”.
●““My Room Mode” has stopped due to
low traction battery”
The remaining charge in the hybrid bat -
tery (traction battery) is insufficient.
Stop using “My Room Mode” and
charge the hybrid battery (traction bat -
tery).
●““My Room Mode” will stop when trac -
tion battery is too low Reduce power

The power consumptio n inside the vehi-
cle is greater tha n the power being
charged to the hybrid battery (traction
battery), and the remaining charge of
the hybrid battery (traction battery) is
low.*
• “My Room Mode” will end unless the power consumption inside the vehicle
is improved.
• To continue using “My Room Mode”, turn off the power of systems such as
the air conditioni ng system and audio
system to increase the remaining charge of the hybrid battery (traction
battery).*: The power balance status during “My
Room Mode” can be checked from the
remaining charge display screen for
the hybrid battery (traction battery)
displayed on the multi-information dis -
play.
WARNING
■Cautions for using “My Room
Mode”
Make sure to observe the following
precautions.
Failure to do so may result in serious health problems or even death.
●Do not leave chil dren, people who need assistance, or pets inside the
vehicle. The sys tem may turn off
automatically and the interior tem- perature may become high or low,
resulting in heat stroke, dehydration
or hypothermia. Devices such as the wipers can also be used, which
may lead to mistaken operation and
an accident.
●Check the safety around the vehicle
carefully before use.

When charging according to the charging
schedule, set “Char ge Now” to off.
( →P.150)
charging schedule is set to offCheck that charging schedule is not set
to off. ( →P.149)
Charging mode is set to “Departure” and
schedule departure time is close to cur -
rent time
When the system dete rmines that there
is no time to finish c harging by the set
scheduled departure time, it starts
charging. Check the charging schedules.
AC charging cable was removed and
reinserted while charging indicator of the
charging port was flashing
If the AC charging cable is removed and
reinserted while the charging indicator is
flashing, the charging schedule is can -
celed ( →P.138).
Temporarily remove the AC charging
cable, and then reconnect it.
The Remote Air Conditioning System

■If “Charging Stopped Due to Pul led Charging Connector” is shown
*: Electricity is consumed when operating “Battery Heater” (→P.128), the air condi-
tioning-linked function ( →P.144) or Remote Air Conditioning System (→P.460).
■If “Charging Complete Limited Due to Battery Temp” is shown
Likely causeCorrection procedure
Charging connector is removed while
charging
When the charging connector is removed
while charging, charging stops. If you
want to fully charge the hybrid battery
(traction battery), reconnect the charging
connector.
After the hybrid battery (traction battery)
is fully charged, the charging connector
is removed while the hybrid battery (trac -
tion battery) is bei ng recharged again
because electricity-consuming func -
tions* have been used and the remaining
charge is now reduced.
Charging connector is not securely con -
nected
Check the connection status of the
charging connector.
• When connecting the charging con-
nector, insert the charging connector
securely.
• After connecting the charging connec-
tor, check that the charging indicator of
the charging port is turned on.
If charging cannot be carried out, even
though the proper procedures were fol -
lowed, have the vehicle inspected by any
authorized Toyota retailer or Toyota
authorized repairer, or any reliable
repairer.
Charging connector was unlocked while
charging
When the charging connector is
unlocked while charging, charging stops.
To continue charging, reconnect the
charging connector.
Likely causeCorrection procedure
Charging was stopped to protect the
hybrid battery (traction battery) as it con -
tinued to remain hot for a certain period
of time.
Allow the hybrid battery (traction battery)
to cool down and perform charging again
if the charging amount has not reached
