• To continue using “My Room
Mode”, turn off the power of sys-
tems such as the air conditioning
system and audio system to
increase the remaining charge of
the hybrid battery (traction bat-

*: The power balance status during
“My Room Mode” can be checked
from the remaining charge dis-
play screen for the hybrid battery

WARNING
■Cautions for using “My Room
Mode”
Make sure to ob serve the follow-
ing precautions.
Failure to do so may result in seri-
ous health problems or even
death.
●Do not leave children, people
who need assistance, or pets
inside the vehicle. The system
may turn off automatically and
the interior temperature 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.
Solar charging sys-
tem*
A system that provides
power to the hybrid battery
(traction battery) and auxil-
iary systems by performing
solar charging via the large
solar panel (solar roof)
equipped on the vehicle
roof.
Even when a parking lot does
not have charging equipment
and in the event of a disaster,
it is possible to charge
* the
hybrid battery (traction bat-
tery) without any special oper-
ations as long as sunlight is
available.
*: The charging amount via the solar charging system differs
depending on conditions, such
as season and weather.

■Solar charging system
●In the following cases, charging
the hybrid battery (traction battery)
via the solar charging system is
not performed.
• The power switch is not off • The “Battery Heater” is operating
( P.108)
• AC charging has started
• The hybrid battery (traction bat-
tery) is fully charged
• The hybrid battery (traction bat-
tery) is completely discharged
●In the following cases, the solar
charging system stops solar
power generation and power sup-
ply to the hybrid battery (traction
battery) and auxiliary systems.
• The temperature preservation function of the solar charging sys-
tem operates
• There is a malfun ction in the solar
charging system
• When the temperature of the hybrid battery (traction battery) is
approximately 23°F (-5°C) or less
●The amount of power generated
by the solar roof differs according
to the season, climate, weather
conditions, vehicle angle and sur-
rounding conditions.
●If even part of the solar roof is in
the shade, there may be an
extreme drop in power generation.
●Please adhere to the following in
order to allow full performance of
the solar roof.
• Clean the roof on a routine basis
(Especially fallen leaves and bird
droppings can lead to a substan-
tial decrease in power generation)
• Remove snow from the roof as soon as possible
• Do not attach any seals or stickers
to the roof
It is recommended not to install a
roof carrier etc. unless it is neces-
sary.
●When the hybrid battery (traction
battery) is fully charged, charging
the battery via the solar charging
system is not performed. When it
is not necessary to perform
charging from an external power
source, charge the vehicle as
much as possible using the solar
charging system during the day

When charging does not start, even though the normal proce-
dure is followed, check each of the following items.
If a message is shown on the multi-information display, also refer
to P.143.

Electrical leakage detection function
or self-diagnostic function operates

When the voltage is insufficient, the
error warning indicator may flash
when there is noise interference.
Perform a reset and connect to a
proper power source. (P.100)
If charging does not start, immedi-
ately stop charging and contact your
Toyota dealer.

When you wish to charge according
to the charging schedule, wait until
the set time.
To start charging, set “Charge Now”
to on. ( P.128, 132)

charging port rapidly flashes
*: Mal-
function occurred in an external
power source or the vehicle
When a door is opened while the
power switch is off, a message will
be displayed on th e multi-information
display. Follow the instructions dis-
played by the message on the multi-
information display.

When a door is opened with the
power switch off, after charging,
a message is displayed in the
multi-information display.
When this occurs, follow the
instructions displayed on the
screen.
AC charging connector was removed
and reinserted while charging indica-
tor of the charging port was flashing
If the AC charging connector is
removed and reinserted while the
charging indicator is flashing, the
charging schedule is canceled
( P.118).
Temporarily remove the AC charging
connector, and then reconnect it.
Outside temperature is low and
hybrid battery (traction battery)
warming control ( P.109) operated
(Alaska and Canada only)
 When hybrid battery (traction bat-
tery) warming control operates, the
charging schedules are ignored
and charging starts. In order to
protect the hybrid battery (traction
battery), allow charging to con-
tinue.
 After the 12-volt battery is removed
and reconnected, the charging
schedule setting may be disabled
due to the initial setting of the tem-
perature control system for the 12-
volt battery, even when the outside
temperature is not low. In this
case, after driving a few times, the
system initial settings will be com-
pleted and the charging schedule
settings will be enabled when the
outside temperature is not low.
