WARNING
■Road accident cautions
Observe the following precautions to reduce the risk of death or serious
injury:
● Pull your vehicle off the road, apply the parking brake, shift the shift posi-
tion to P, and turn the hybrid system off.
● Do not touch the high voltage parts, cables and connectors.
● If electric wires are exposed inside or outside your vehicle, an electric
shock may occur. Never touch exposed electric wires.
● Do not touch the battery if liquid is leaking from or adhering to it.
If electrolyte (carbonic-based organic electrolyte) from the hybrid battery
(traction battery) comes into contact with the eyes or skin, it could cause
blindness or skin wounds. In the unlikely event that it comes into contact
with the eyes or skin, wash it off immediately with a large amount of water,
and seek immediate medical attention.
● If electrolyte is leaking from the hybrid battery (traction battery), do not
approach the vehicle.
Even in the unlikely event that the hybrid battery (traction battery) is dam-
aged, the internal construction of the battery will prevent a large amount of
electrolyte from leaking out. However, any electrolyte that does leak out
will give off a vapor. This vapor is an irritant to skin and eyes and could
cause acute poisoning if inhaled.
● Do not bring burning or high-temperat ure items close to the electrolyte.
The electrolyte may ignite and cause a fire.
● If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possible.
Never use a fire extinguisher that is not meant for electric fires. Using even
a small amount of water may be dangerous.
● If your vehicle needs to be towed, do so with front wheels raised. If the
wheels connected to the electric motor (traction motor) are on the ground
when towing, the motor may continue to generate electricity. This may
cause a fire. ( →P. 646)
● Carefully inspect the ground under the vehicle. If you find that liquid has
leaked onto the ground, the fuel system may have been damaged. Leave
the vehicle as soon as possible.

WARNING
■Hybrid battery (traction battery)
● Your vehicle contains a sealed lithium-ion battery.
● Never resell, hand over or modify the hybrid battery. To prevent accidents,
hybrid batteries that have been removed from a disposed vehicle are col-
lected through Toyota dealer. Do not dispose of the battery yourself.
Unless the battery is properly collected, the following may occur, resulting
in death or serious injury:
• The hybrid battery may be illegally disposed of or dumped, and it is haz-
ardous to the environment or someone may touch a high voltage part,
resulting in an electric shock.
• The hybrid battery is intended to be used exclusively with your hybrid vehicle. If the hybrid battery is used outside of your vehicle or modified
in any way, accidents such as electric shock, heat generation, smoke
generation, an explosion and electrolyte leakage may occur.
When reselling or handing over your vehicle, the possibility of an acci-
dent is extremely high because the person receiving the vehicle may
not be aware of these dangers.
● If your vehicle is disposed of without the hybrid battery having been
removed, there is a danger of serious electric shock if high voltage parts,
cables and their connectors are touched. In the event that your vehicle
must be disposed of, the hybrid battery must be disposed of by your Toy-
ota dealer or a qualified service shop. If the hybrid battery is not disposed
of properly, it may cause electric shock that can result in death or serious
injury.

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 0
■
Automatic check function
This is an automatic system chec k that is run before charging
begins to check for problems in t he 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. 110)
■
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 Interrupt ing Device) is designed to pre-
vent electrical current from bei ng 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).

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

■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.
If they are dropped into water, contact your Toyota dealer.
● Do not bring the charging cable to a high-temperature item such as a heat-
ing device.
● Do not wrap the charging cable around the CCID (Charging Circuit Inter-
rupting Device).
NOTICE
■When use the charging cable and related parts
→ P. 145
■ 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 th e 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.
