Charging tips
To enable the use of EV mode, we recommend systematically
charging the vehicle.
Before leaving home
In order to use EV mode, charge
the hybrid battery (traction battery)
at home before leaving.
The charging schedule function
(P. 157) can be used to set the
system to automatically fully
charge the hybrid battery (traction
battery) before your desired depar-
ture time. It is also possible to set
the air conditioning to make the
interior in a comfortable state
before your desired departure time.
At your destination
Use a public charging station to
charge the hybrid battery (traction
battery).
If there are no charging facilities at
your destination, the hybrid battery
(traction battery) can be charged
using the hybrid battery (traction
battery) charge mode. (P. 89)
*
After returning home
In order to drive the next time, charge the hybrid battery (traction battery).
Settings the charge schedule allows you to charge the hybrid battery (trac-
tion battery) at the desired time such as late at night or early in the morn-
ing. Furthermore, the charging schedule can be set to automatically
charge the hybrid battery (traction battery) every day or at the same time
on certain days. (P. 157)

Using the charging schedule function
When registering the charge schedule, the following settings can be
changed.
■Select the charging mode
One of the two following charging modes can be selected.
*1: Charging schedule function is performed in accordance with the clock in
the instrument cluster. Before registering the charge schedule, check the
clock settings to the proper time.
*2: There might be a slight error in the timing when charging starts due to the
state of the hybrid battery (traction battery).
■
Repeated setting
The periodic charging schedule can be set by selecting your
desired day of the week.
■Air conditioning-linked setting (“Climate Prep”)
When the charging mode is set to “Departure”, the vehicle air condi-
tioning system (P. 512, 524) can be set to automatically operate*
according to the set time.
By adjusting the cabin temperature in advance, passengers can enjoy a
pleasant interior immediately after entering the vehicle.
*: Operation starts approximately 10 minutes before the set departure time.
Charging can be carried out at the desired time by registering
the charge schedule. Also, it is possible to set the charging
schedule to one’s preferences, such as having charging com-
plete by a certain departure time or be carried out at the same
time on certain days.

■Charging schedule
●The charge schedule cannot be set while driving.
●A maximum of 15 charge schedules can be registered.
■To make sure that the charging schedule function operates correctly
Check the following items.
●Adjust the clock to the correct time (P. 197)
●The calendar is set to the correct date (P. 199)
●Check that the power switch is turned off
●After registering the charge schedule, connect the charging cable
The charging start time is determined based on the charge schedule at the
time that the charging cable was connected.
●After connecting the charging cable, check that the charging indicator
flashes (P. 114)
●Do not use an outlet that has a power cut off function (including a timer func-
tion)
Use an outlet that constantly supplies 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 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”
●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.
■Smartphone-linked operation (vehicles with 11.6-inch display)
After applying to Entune App Suite, it is possible to use the smartphone appli-
cation to change charging schedule settings.
