When starting My Room Mode,
the electric power balance will
be automatically displayed on
the multi-information display,
and an approximation of the
electricity balance (the balance
between the amount of electric-
ity provided and electricity con-
sumed) during My Room Mode
can be checked.

Meter display while charging

After turning the power switch to ON

while charging, the power switch

automatically turns off if My Room

Mode is not selected within approxi-

mately 100 seconds.

■

When using My Room Mode the

following may occur

●

When the remaining charge of the

traction battery drops to the lower

limit, the air conditioning system

automatically stops. In that case,

the air conditioning system can

not operate until the remaining

charge of the traction battery

increases. Turn off the power

switch once, then use My Room

Mode after the remaining charge

of the traction battery increases.

●

The charging time of the traction

battery gets longer.

●

Noise may be heard from the

radio depending on conditions of

the radio wave.

●

The surrounding area of the

onboard traction battery charger

in the motor compartment may

become hot.

●

The electric power steering sys-

tem warning light (yellow) may

turn on, but this is not a malfunc-

tion.

■

Using My Room Mode during

DC charging

When using My Room mode during

DC charging, the state of charge

completion will be lower than when

not using My Room Mode.

■

When “My Room Mode” is used

while the traction battery is fully

charged

When the power switch is turned on
while the traction battery is fully
charged and the charging connector
that supplies power is connected,
“Charging Port Lid is Open” is dis-
played on the multi-information dis-

Warning message display

When trying to start My Room Mode or My Room Mode is being used, if a

message is displayed on the multi-information display, refer to the corre-

sponding table and perform the appropriate correction procedures.

: During My Room Mode, the information for electric power balance can be

checked on the multi-information display.

Message

Correction procedure

“Traction Battery is too
Low for “My Room
Mode””

There is no remaining charge of the traction bat-
tery to start My Room Mode. Wait until the
remaining charge of the traction battery
increases, start My Room Mode.

““My Room Mode” has
stopped due to low trac-
tion battery level”

The remaining charge of the traction battery is
insufficient. Stop using My Room Mode and
charge the traction battery.

““My Room Mode” will
stop when traction bat-
tery level is too low
Reduce power usage to
continue using “My
Room Mode””

When My Room mode electricity consumption
exceeds the charge amount, the traction battery
charge level becomes too low.

• If the electricity consumption of the vehicle can

not be improved, My Room Mode will be off.

• When My Room Mode continuation is desired,

turn off the air conditioning system, audio sys-
tem, etc., to increase the remaining charge of
the traction battery.

WARNING

■

Warnings for using My Room

Mode

Observe the following precau-

tions.
Failure to do so may result in

death or a serious health hazard.

●

Do not leave children, people

who need care, or pets inside

the vehicle. The temperature

inside the vehicle may become

high or low due to features such

as the automatic shut-off. The

children, people who need care,

or pets left inside the vehicle

may suffer heatstroke dehydra-

tion or hypothermia. Also, since

the wipers, etc., can be oper-

ated, there may be accidental

operation, possibly leading to

an accident.

●

Use the mode after sufficiently

checking the vicinity of the vehi-

cle for safety hazards.
