The illumination/flashing pattern
changes to inform the user of the
charging status in the following
ways.
*: 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.

2-2. Charging
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. 1 1 8
■
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. 118)
■
Temperature detection function
A temperature detection function is equipped to the plug. While
charging, if heat is generated due to looseness on the outlet side
etc., this function suppresses heat by controlling the charging cur-
rent.
■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 outlet.

■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.

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 outlet 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.
*1: When this occurs, charging is carried out without a limited charging current.
*2: When this occurs, charging is carried out with a limited charging current.

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 charging cable or the CCID (Charging Circuit
Interrupting Device), stop charging immediately and contact your Toyota
dealer.
●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).
●Do not use or leave the charging cable in situations where a load is
applied to the outlet and the plug (such as when the CCID (Charging Cir-
cuit Interrupting Device) is hanging in the air without contacting the
ground).
NOTICE
■When use the charging cable and related parts
P. 155
■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.

2-2. Charging
For safety, inspect the charging cable on a routine basis.
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 outlet has not been damaged
●The plug can be securely inserted into the outlet
●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 outlet before inspecting it. If any abnormalities
are found in the charging cable as a result of the inspection, immediately
stop use and consult your Toyota dealer.
■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 occur during charging, possibly resulting in
death or serious injury.
■When not using the charging cable for a long time
Remove the plug from the outlet. Dust could accumulate on the plug or in
the outlet, possibly causing overheating which could lead to a fire.
Also, keep the cable in a place free from moisture.
