schedule, set “Charge Now” to “Off”.
(P. 184)
Charge schedule is set to
“Off”Check that charge schedule is not set to
“Off”. (P. 1 8 2 )
Charging mode is set to
“Departure” and schedule
departure time is close to
current timeWhen the system determines that there is
no time to finish charging by the set sched-
uled departure time, it starts charging.
Check the charge schedules.
Charging cable was
removed and reinserted
while charging indicator was
flashingIf the charging cable is removed and rein-
serted while the charging indicator is flash-
ing, the charging schedule is canceled
(P. 168). Temporarily remove the charging
cable, and then reconnect it.
The Remote Air Conditioning

before charging starts. Check the status of
the charging indicator. (P. 125)
Charging ends earlier than time set in “Departure”
Charging end time does not
match estimated end time
due to condition of power

conditioning operates until the set departure
time. Therefore, charging may not complete
by the set time due to charging conditions.
To have the hybrid battery (traction battery)
fully charged, allow charging to continue.
Charging end time does not
match estimated end time
due to condition of power
source or outside tempera-
tureIf sudden changes in temperature or
changes in the condition of the power
source occur while charging, charging may
not end exactly at the time estimated by the
