Plug-in hybrid system
Prius Plug-in Hybrid_OM_OM47D72E_(EE)
This product must be grounded. In case of malfunction or break down,
grounding provides a path of least resistance for electric current to
reduce the risk of electric shock. This product is equipped with a
grounding conductor and a grounding plug. The grounding plug must
be plugged into an appropriate socket that is properly installed and
grounded in accordance with all local codes and ordinances.
The CCID (Charging Circuit Interrupting Device) has the following
safety features.
■Electrical leakage detection function
If an electrical leakage is detected during charging, the power
source will be automatically interrupted, thus preventing fires or
electrical shocks caused by electrical leakage.
If the power source is interrupted, the error warning indicator flashes.
If the power source is interrupted: P. 130
■Automatic check function
This is an automatic system check that is run before charging
begins to check for problems in the operation of the electrical leak-
age detection function.
If a malfunction is found in the electrical leakage detection function as a
result of the check, the error warning indicator flashes to inform the
user. ( P. 130)
■Temperature detection function
A temperature detection function is equipped to the plug. While
charging, if heat is generated due to looseness on the socket side
etc., this function suppresses heat by controlling the charging cur-
rent.
Grounding (Mode 2 charging cable)
WARNING
■ Grounding precautions
● Improper connection of the grounding conductor increases the risk of elec-
tric shock. Check with a qualified electrician or serviceman if you are in
doubt as to whether the product is properly grounded.
● Do not modify the grounding plug provided with the product. If it does not
fit the socket, have a proper socket installed by a qualified electrician.

■Conditions for supplying current to the vehicle
The CCID (Charging Circuit Interrupting Device) is designed to pre-
vent electrical current from being supplied to the charging connec-
tor when it is not connected to the vehicle, even if the plug is
inserted into the socket.
■Indicator operation
3 indicators are used to indicate the following conditions.
Power indicator
Illuminates when electricity is
flowing to the CCID (Charging
Circuit Interrupting Device).
Charging indicator
Illuminates when charging is in
progress.
Error warning indicator
Flashes when there is an electri-
cal leakage or when a malfunc-
tion occurs in the CCID
(Charging Circuit Interrupting
Device).
■
When a malfunction occurs during charging
The indicators on the CCID (Charging Circuit Interrupting Device)
use a combination of different statuses (not illuminated, illuminated
or flashing) to inform the user of internal malfunctions.
When the error warning indicator is illuminated or flashing, temporarily
remove the plug from the socket and then reconnect it to check if the
error indicator turns off.
If the error warning indicator turns off, charging is now possible.
If it does not turn off, perform the correction procedure in the following
chart.

The plug-cord can be replaced using the following procedure.
Prepare the charging cable
( P. 126) and the replacement
plug-cord.
Pull out the release key.
Make sure that the pulled out
release key is not lost.
Remove the plug-cord connec-
tor cap.
Insert the release key into the
release slot of the CCID
(Charging Circuit Interrupting
Device).
Insert the release key in the direc-
tion shown in the illustration.

With the release key fully
inserted into the release slot of
the CCID (Charging Circuit
Interrupting Device), turn the
plug-cord connector nut of the
plug-cord to remove the cord.
After the plug-cord is removed,
remove the release key.
Do not leave the vehicle alone with the plug-cord removed. If the plug-cord
is not installed, water or other foreign matter may enter the CCID
(Charging Circuit Interrupting Device), resulting in a malfunction.
Align the protrusion of the CCID
(Charging Circuit Interrupting
Device), with the groove of the
plug-cord, insert the plug-cord
into the CCID (Charging Circuit
Interrupting Device), and then
turn the plug-cord connector
nut of the plug-cord to install it.
Make sure that there are no foreign
objects attached to the connection
before installing the plug-cord.
Remove any foreign objects if they
are attached. Otherwise, water or
other foreign matter may enter the
CCID (Charging Circuit Interrupting
Device), resulting in a malfunction.
Turn the plug-cord connector nut of the plug-cord in the opposite direction
of removal until a click sound is heard and the plug-cord is secured.
Install the plug-cord connector cap and release key to the plug-cord
that has been removed.
Securely install the release key to the protection cap to prevent it from
being lost. Also, make sure that the release key does not fall out of the pro-
tection cap accidently.
Store the plug-cord in a safe, clean and dry place.

WARNING
■When using the charging cable and CCID (Charging Circuit Interrupt-
ing Device)
Observe the following precautions.
Failure to do so may cause an unexpected accident, resulting in death or
serious injury.
● Do not attempt to disassemble or repair the charging cable, charging con-
nector, plug or CCID (Charging Circuit Interrupting Device).
If a problem arises with the chargi ng cable or the CCID (Charging Circuit
Interrupting Device), stop charging immediately and contact any autho-
rized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
● Do not subject the charging cable, charging connector, plug or CCID
(Charging Circuit Interrupting Device) to strong force or impact.
● Do not apply excessive force to the charging cable by forcefully folding,
twisting, pulling or dragging the charging cable.
● Do not damage the charging cable with sharp objects.
● Do not fold the charging connector or plug or insert foreign objects into
them.
● Do not put the charging connector and plug into water.
● Do not bring the charging cable to a high-temperature item such as a heat-
ing device.
● Do not apply a load to the charging cable and plug-cord (such as wrapping
the charging cable around the CCID (Charging Circuit Interrupting Device)
and the charging connector).

NOTICE
■When use the charging cable and related parts
 P. 174
■ Precautions for low temperatures
In low temperatures, the charging cable and plug-cord may become hard.
Therefore, make sure to not apply excessive force when they are hard. If
excessive force is applied to the hardened charging cable and plug-cord,
they may be damaged.
■ Precautions for the plug-cord (if equipped)
Do not use the plug-cord for any use other than charging this vehicle. Doing
so may cause the plug-cord to be damaged.

Inspecting and maintaining the charging cable
WARNING
■Routine inspection
Check the following points regularly.
Failure to do so may cause an unexpected accident, resulting in death or
serious injury.
● The charging cable, plug, charging connector, CCID (Charging Circuit
Interrupting Device) etc. have not been damaged
● The socket has not been damaged
● The plug can be securely inserted into the socket
● The plug does not get extremely hot during use
● The tip of the plug has not been deformed
● The plug is not dirtied by dust etc.
Remove the plug from the socket before inspecting it. If any abnormalities
are found in the charging cable as a result of the inspection, immediately
stop use and consult any authorized Toyota retailer or Toyota authorized
repairer, or any reliable repairer.
■ Maintaining the charging cable
When the charging cable is dirty, first remove the dirt with a hard, wringed
cloth, and then wipe the cable with a dry cloth.
However, never wash it with water. If the charging cable is washed with
water, fire or electric shock may oc cur during charging, possibly resulting in
death or serious injury.
■ When not using the charging cable for a long time
Remove the plug from the socket. Dust could accumulate on the plug or in
the socket, possibly causing overheating which could lead to a fire.
Also, keep the cable in a place free from moisture.
