1Connect the AC charging
cable to the vehicle and start
charging
2 Turn the power switch on
during charging
The setting screen of “My Room
Mode” is displayed automatically on
the multi-information display.
3Press or of the meter
control switches, select
“Yes”, and then press .
“My Room Mode” starts and sys-
tems such as the air conditioning
system and audio system can be
used inside the vehicle.
When not using “My Room Mode”,
select “No”, and then press .
To stop “My Room Mode”, turn
the power switch off.
When “My Room Mode” starts,
the remaining charge display screen for the hybrid battery

automatically on the multi-infor-
mation display. The approxi-
mate power balance (balance
between electricity supply and
consumption) while using “My
Room Mode” can be checked
from the 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 vehi-
cle, becomes larger. When the
power consumption is larger than
the electricity supply, becomes
larger.
When the electricity supply and
consumption are balanced (when
the power balance is judged to be
zero), and are displayed as
the same size.
■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 auto-
matically turn off.
Using the “My Room

■While using “My Room Mode”
Any of the following may occur.
●When the remaining charge of the
hybrid battery (traction battery)
reaches the lower limit, the air
conditioning system automatically
turns off.
In this situation, the air conditioning
system cannot be used until the
remaining charge of the hybrid bat-
tery (traction battery) increases.
Turn the power switch off and use
“My Room Mode” after the remain-
ing charge of the hybrid battery
(traction battery) is restored.
●When the outside temperature is
low, the heater output may be lim-
ited due to the air conditioning
system operation being restricted.
●Warning lights and indicators such
as electric power steering system
warning light (yellow) and mal-
function indicator lamp may turn
on, but this is not a malfunction.
Also, when the headlight switch is
in the AUTO position (if equipped)
and the surrounding area is dark,
the headlights are turned on.
(  P.269)
■When a charging schedule is
registered
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 (trac-
tion battery) is fully charged
When the power switch is turned on
while the hybrid battery (traction
battery) is fully charged and the
charging connector that supplies
power is connected, “Charging Port
Lid is Open” is displayed on the
multi-information di splay. In this
case, press on the 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 electric
power of the hybrid battery (traction
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 attempti ng to start “My
Room Mode”, take the following cor-
rection procedures.
●“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
battery (traction battery) increases,
then start “My Room Mode”.
●““My Room Mode” has stopped
due to low traction battery”
The remaining charge in the hybrid
battery (traction ba ttery) is insuffi-
cient.
Stop using “My Room Mode” and
charge the hybrid battery (traction
battery).
●““My Room Mode ” will stop when
traction battery is too low Reduce
power usage to continue using
“My Room Mode””
The power consumption inside the
vehicle is greater than 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

1362-2. Charging
the power consumption inside the
vehicle is improved.
• 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-
tery).
*: The power balance status during
“My Room Mode” can be checked
from the remaining charge dis-
play screen for the hybrid battery
(traction battery) displayed on the
multi-informat ion display.
(  P.134)
*: If equipped
This system generates solar
power with the solar panel
equipped to the roof of the vehi-
cle (solar roof).
 The hybrid battery (traction
battery) is charged while park-
ing.
 The electrical consumption of
the hybrid battery (traction
battery) is reduced during
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

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.
