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

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.

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.

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.
