melting when the temperature rises due
to foreign matter ent ering the charging connector. When a certain temperature
increase is detected, charging is
stopped immediately and a message is displayed on the multi-information dis -
play. After the temperature has
decreased, charging resumes by per - forming the operation to start charging
again.
WARNING
■When charging
Observe the following precautions.
Failure to do so may cause an unex -
pected accident, resulting in death or
serious injury.
●Connect to a power source suitable
for charging. ( →P.124)
●Check that the AC charging cable,
plug and socket are free of foreign
matter.
●Before charging, check that the AC
charging inlet is not deformed, damaged or corroded, and check
that the inlet is fr ee of foreign mat-
ter such as dirt , snow and ice. If there is dirt or dust in these areas,
remove completely before inserting
the charging connector.
●Before inserting the charging plug into the charger, make sure there is
no dirt or dust on the terminal
areas. If there is dirt or dust in these areas, remove completely before
inserting the charging plug.
●Do not get the terminals of the AC
charging inlet wet.
●Only use sockets where the plug
can be securely inserted.
●Do not bundle or wind the AC
charging cable while charging, as
doing so may result in overheating.
●Do not touch the te rminals of the
charging connector and AC charging inlet with a sharp metal
objects (needles etc.) or hands, or
short them with foreign objects.
●When charging ou tdoors, make
sure to connect to a rain-tight socket for outdoor u se. Ensure the
rain-tight cover closes completely. If
the rain-tight cover cannot be closed, install a rain-tight cover that
will close.
●In order to stop charging at the
charging station, f ollow the instruc-
tions of the charger.
●If any heat, smoke , odors, noise or
other abnormaliti es are noticed during charging, stop charging
immediately.
●Do not insert the plug if the socket
is submerged in water or snow.
●When charging while it is raining or
snowing, do not connect or discon -
nect the plug if your hands are wet.
Also, do not get the plug or outlet wet.
●Do not charge the vehicle during a lightning storm.
●Prevent the AC charging cable from being caught in the door or back
door.

connected.
●After connecting the AC charging
cable, check that the charging indica -
tor of the charging port flashes ( →P.106)
●Do not use an socket that has a power cut off function (including a timer func -
tion)
Use an socket that constantly supplies electricity. For sockets where the
power is cut off due to a timer func -
tion, etc., charging may not be carried out according to plan if the power is
cut off during the set time.
■When the AC charging cable
remains connected to the vehicle
Even if multiple consecutive charging
schedules are registered, the next
charge will not be ca rried out according to the charging schedule until the AC
charging cable is removed and recon-
nected after charging completes. Also, when the hybrid battery (traction battery)
is fully charged, charging according to
the charging schedule will not be carried out.
■“Climate Prep”
●When the air condit ioning-linked set- ting is turned on, the air conditioning
operates until the se t departure time.
Therefore, the air conditioning will consume electricity and charging may
not complete by the set departure
time.
●If the hybrid battery (traction battery)
is fully charged, cha rging will not be carried out, even if the charging
schedule is set. However, if “Climate
Prep” is turned on, the air conditioning will operate only once when it nears
the time set in “De parture”. If this
occurs, the air conditioning will con -
sume electricity and the remaining charge of the hybrid battery (traction
battery) when departing may be
decreased.
●When the doors are unlocked, the air
conditioning system does not operate.
■When charging schedules are
ignored
When the following operations are per -
formed while the charging schedule is
on standby, charging schedule is tempo - rarily canceled and charging is started.
●When the Remote Air Conditioning System ( →P.460) is operated
●When turning “My Room Mode” on ( →P.153)
●When turning “Charge Now” on ( →P.150)
●When an operation that temporarily cancel charging using the charging
schedule ( →P.138)
■Effects of outside temperature
When the charging mode is set to “Departure”, chargin g schedule may be
ignored due to the outside temperature
and charging may start.
■“Battery Heater” ( →P.128) /“Battery Cooler” ( →P.129)
When charging is carried out using the
charging schedule, the hybrid battery (traction battery) heating or cooling func -
tion may operate according to the tem -
perature of the hybrid battery (traction battery).
●When the charging mode is set to “Start”, the function starts at the set
charging start time.
●“Battery Heater”: When the charging
mode is set to “Dep arture”, the func-
tion starts automatic ally to complete heating by the desired departure time.
●“Battery Cooler”: When the charging mode is set to “Dep arture”, cooling
starts approximately 30 minutes
before the charging start time. How -
ever, if there is no time to finish charging by the charging schedule,
the hybrid battery (traction battery)
cooling time may be shortened and “Battery Cooler” may not operate.
