Prius Plug-in Hybrid_OM_OM47D72E_(EE)
If the charging indicator flashes
after inserting the charging con-
nector:
The charge schedule is regis-
tered (P. 176). Carry an elec-
tronic key and press the
charging connector lock switch

If the error warning indicator on the CCID (Charging Circuit Interrupting
Device) flashes during charging, check P. 130 and follow the correction
procedure.
The charging indicator will turn off when charging is completed.
■During charging
●The surface of the CCID (Charging Circuit Interrupting Device) may become
hot, but this does not indicate a malfunction. (When using Mode 2 charging
cable.)
●Depending on radio wave conditions, interference may be heard on the
radio.
●The current charging condition and the estimated time until charging will
complete can be checked on the multi-information display. (P. 159)
●During charging, the hybrid battery (traction battery) status indicator illumi-
nates and flashes, and changes according to the charging amount.
(P. 123)
■If the charging indicator flashes after connecting the charging cable
The charge schedule (P. 176) is registered and charging cannot be per-
formed. To cancel charging using the charging schedule and start charging,
perform any of the following procedures.
●Turn “Charge Now” on (P. 184)
●While the charging indicator is flashing, remove and reconnect the charging
connector within 5 seconds

Operation of each component
■Note for the entry function
●Even when the electronic key is within the effective range (detection areas),
the system may not operate properly in the following cases:
• The electronic key is too close to the window or outside door handle, near
the ground, or in a high place when the doors are locked or unlocked.
• The electronic key is on the instrument panel, floor, or in the door pockets
or glove box when the hybrid system is started or power switch modes
are changed.
●Do not leave the electronic key on top of the instrument panel or near the
door pockets when exiting the vehicle. Depending on the radio wave recep-
tion conditions, it may be detected by the antenna outside the cabin and the
door will become lockable from the outside, possibly trapping the electronic
key inside the vehicle.
●As long as the electronic key is within the effective range, the doors may be
unlocked or locked by anyone.
●Even if the electronic key is not inside the vehicle, it may be possible to start
the hybrid system if the electronic key is near the window.
●The doors may unlock if a large amount of water splashes on the door han-
dle, such as in the rain or in a car wash when the electronic key is within the
effective range. (The door will automatically be locked after approximately
30 seconds if the doors are not opened and closed.)
●If the wireless remote control is used to lock the doors when the electronic
key is near the vehicle, there is a possibility that the door may not be
unlocked by the entry function. (Use the wireless remote control to unlock
the doors.)
●Touching the door lock sensor while wearing gloves may delay or prevent
lock operation. Remove the gloves and touch the lock sensor again.
●On some models: When the lock operation is performed using the lock sen-
sor, recognition signals will be shown up to two consecutive times. After this,
no recognition signals will be given.
●If the door handle becomes wet while the electronic key is within the effec-
tive range, the door may lock and unlock repeatedly. In this case, follow the
following correction procedures to wash the vehicle.
• Place the electronic key in a location 2 m (6 ft.) or more away from the
vehicle. (Take care to ensure that the key is not stolen.)
• Set electronic key to battery-saving mode to disable the smart entry &
start system. (P. 295)

If the vehicle is left in ACCESSORY mode for more than 20 minutes or ON
mode (the hybrid system is not operating) for more than an hour with the shift
position in P, the power switch will automatically turn off. However, this func-
tion cannot entirely prevent the 12-volt battery discharge. Do not leave the
vehicle with the power switch in ACCESSORY or ON mode for long periods
of time when the hybrid system is not operating.
■Sounds and vibrations specific to a hybrid vehicle
P. 106
■Electronic key battery depletion
P. 280
■When the ambient temperature is low, such as during winter driving con-
ditions
●When starting the hybrid system, the flashing time of the “READY” indicator
may be long. Leave the vehicle as it is until the “READY” indicator is steady
on, as steady means the vehicle is able to move.
●When the hybrid battery (traction battery) is extremely cold (below approxi-
mately -30C [-22F]) under the influence of the outside temperature, it may
not be possible to start the hybrid system. In this case, try to start the hybrid
system again after the temperature of the hybrid battery increases due to
the outside temperature increase etc.
