■System malfunction
*1: The system judges a person of adult size as an adult. When a smaller adult sits in the front passenger seat, the system may not recognize
them as an adult depending on their physique and posture.
*2: In the event the front passenger is wearing a seat belt.
*3: In the event the front passenger does not wear a seat belt.
*4: For some children, child in seat, child in booster seat or child in convert-
ible seat, the system may not recognize them as a child. Factors which
may affect this can be the physique or posture.
*5: Never install a rear-facing child rest raint system on the front passenger
seat. A forward-facing child restraint system should only be installed on
the front passenger seat w hen it is unavoidable. (P.54)
*6: In case the indicator light is not illu minated, consult this manual on how
to install the child restraint system properly. ( P.51)

Plug-in hybrid system
■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.

■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

When “My Room Mode” is used
while the hybrid
battery (traction

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.
