The illumination/flashing pattern
changes to inform the user of the
charging status in the following
ways.
*1: If equipped
*2: Turns off after flashing for a certain period of time.
■Charging indicator
When a system malfunction occurs while charging or using the Remote Air
Conditioning System, the charging indicator rapidly flashes for a certain
period of time, and then turns off.
If this occurs, the next time the hybrid system is started, a message is dis-
played on the multi-information display. When a message is displayed, follow
the instructions displayed on the screen.

■ Charging cable types
The following charging modes are categorized according to the availability of
a charging control device, which detects malfunctions such as electrical leak-
ages, and its location (whether it is attached to the charger or charging
cable). The type of charging cable that can be used differs according to the
charging mode.

4
Charging modeOutline
Mode 1
A charging method which does not use charging
control to detect electrical leakages between an
external power source and the vehicle.
Does not apply to this vehicle.
Mode 2
A charging method which connects the vehicle to an
external power source through a charging cable
equipped with a CCID (Charging Circuit Interrupting
Device).
Applies to charging through most household sock-
ets.
Mode 3
A charging method which charges from a charger
(such as at a public charging station) equipped with
charging control to detect electrical leakages. Con-
trol to detect electrical leakages is implemented on
the charger side. Therefore, a CCID (Charging Cir-
cuit Interrupting Device) is not equipped to the
charging cable.
Not all chargers are equipped with charging cables.
If there is no charging cable available, use the Mode
3 charging cable equipped to this vehicle. (if
equipped)

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.

Prius Plug-in Hybrid_OM_OM47D72E_(EE)
■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.
