■To make sure that the charging
schedule function operates cor-
rectly
Check the following items.
●A d j u s t t h e c l o c k t o t h e c o r r e c t t i m e
(  P.169)
●The calendar is set to the correct
date ( P.177)
●Check that the power switch is
turned off
●After registering the charging
schedule, connect the AC
charging cable
The charging sta rt time is deter-
mined based on the charging
schedule at the time that the AC
charging cable was connected.
●After connecting the AC charging
cable, check that the charging
indicator of the charging port
flashes ( P.100)
●Do not use an ou tlet that has a
power cut off function (including a
timer function)
Use an outlet that constantly sup-
plies electricity. For outlets where
the power is cut off due to a timer
function, 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 vehi-
cle
Even if multiple consecutive
charging schedules are registered,
the next charge will not be carried
out according to the charging
schedule until the AC 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”
●When the air conditioning-linked
setting is turned on, the air condi-
tioning operates until the set departure time. Therefore, the air
conditioning will co
nsume electric-
ity and charging may not complete
by the set departure time.
●If the hybrid batte ry (traction bat-
tery) is fully charged, charging will
not be carried o ut, even if the
charging schedule is set. How-
ever, if “Climate Prep” is turned
on, the air conditioning will oper-
ate 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.
■Smartphone-linked operation
(vehicles with Premium Audio)
After applying to Toyota Apps, it is
possible to use the smartphone
application to change charging
schedule settings.
For details about Toyota Apps, refer
to
http://www.toyota.com/connectedse
rvices in the United States and
http://www.toyota.ca/connected
in
Canada.
■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 Condition-
ing System ( P.405) is operated
●When turning “My Room Mode”
on ( P.144)
●When turning “Charge Now” on
( P.137, 142)
●When an operation that temporar-
ily cancel charging using the
charging schedule ( P.125)

■Effects of outside temperature
When the charging mode is set to
“Departure”, charging schedule may
be ignored due to the outside tem-
perature and charging may start.
■“Battery Heater” ( P.115) /
“Battery Cooler” ( P.116)
When charging is c arried out using
the charging schedule, the hybrid
battery (traction battery) heating or
cooling function may operate
according to the te mperature 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 “Depar-
ture”, the function starts automati-
cally to complete heating by the
desired departure time.
●“Battery Cooler”: When the
charging mode is set to “Depar-
ture”, cooling starts approximately
30 minutes before the charging
start time. However, if there is no
time to finish charging by the
charging schedule, the hybrid bat-
tery (traction battery) cooling time
may be shortened and “Battery
Cooler” may not operate.
