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
