■When the charging cable remains connected to the vehicle
Even if multiple consecutive charge schedules are registered, the next
charge will not be carried out according to the charging schedule until the
charging cable is removed and reconnected 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” (if equipped)
●When the air conditioning-linked setting is turned on, the air conditioning
operates until the set departure time. Therefore, the air conditioning will con-
sume electricity and charging may not complete by the set departure time.
●If the hybrid battery (traction battery) is fully charged, charging will not be
carried out, even if the charge schedule is set. However, if “Climate Prep” is
turned on, the air conditioning will operate only once when it nears the time
set in “Departure”. If this occurs, the air conditioning will consume 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 performed while the charging schedule is
on standby, charging schedule is temporarily canceled and charging is
started.
●When the Remote Air Conditioning System (P. 585) is operated
●When turning “Charge Now” on (P. 184)
●When an operation that temporarily cancels charging using the charging
schedule is performed (P. 168)
■Effects of outside temperature
When the charging mode is set to “Departure”, charging schedule may be
ignored due to the outside temperature and charging may start.
■“Traction Battery Cooler” (if equipped) (P. 155)
When charging is carried out using the charging schedule, the hybrid battery
(traction battery) cooling function may operate according to the temperature
of the hybrid battery (traction battery).
●When the charging mode is set to “Start”, cooling starts at the set charging
start time.
●When the charging mode is set to “Departure”, cooling starts approximately
30 minutes before the charging start time. However, if there is no time to fin-
ish charging by the charging schedule, the hybrid battery (traction battery)
cooling time may be shortened and “Traction Battery Cooler” may not oper-
ate.
