■Timer settings
●The charge schedule cannot be set while driving.
● A maximum of 15 charge schedules can be registered.
■ To make sure that the charging timer function operates correctl y
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

power is cut off due to a timer function, etc., charging may no t be carried
out according to plan if the power is cut off during the set ti me.
■ When the charging cable remains connected to the vehicle
Even if multiple consecutive charge schedules are registered, t he next
charge will not be carried out according to the timer until the charging cable is
removed and reconnected after charging completes. Also, when th e hybrid
battery (traction battery) is fully charged, charging according to the timer 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 condi tioning will con-
sume electricity and charging may not complete by the set depar ture time.
● If the hybrid battery (traction battery) is fully charged, char ging 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 c onsume electricity
and the remaining charge of the hybrid battery (traction batter y) when
departing may be decreased.
