WARNING
■Road accident cautions
Observe the following precautions to reduce the risk of death o r 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 hy brid 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 bat tery), do not
approach the vehicle.
Even in the unlikely event that the hybrid battery (traction ba ttery) is dam-
aged, the internal construction of the battery will prevent a l arge amount of
electrolyte from leaking out. However, any electrolyte that doe s 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-tem perature 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. Th is may
cause a fire. ( P. 664)
● 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 preven t accidents,
hybrid batteries that have been removed from a disposed vehicle are col-
lected through Toyota dealer. Do not dispose of the battery you rself.
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 p art,
resulting in an electric shock.
• The hybrid battery is intended to be used exclusively with you r 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 havin g been
removed, there is a danger of serious electric shock if high vo ltage 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 dea th or serious
injury.

Plug-in hybrid system
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 9
■
Automatic check function
This is an automatic system check that is run before charging
begins to check for pr oblems in the operation of the electrical leak-
age detection function.
If a malfunction is found in the electrical leakage detection f unction as a
result of the check, the error warning indicator flashes to inf orm the
user. ( P. 119)
■
Temperature detection function
A temperature detection function is equipped to the plug. While
charging, if heat is generated due to looseness on the outlet s ide
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 bei ng supplied to the charging con nec-
tor when it is not connected to the vehicle, even if the plug i s
inserted into the outlet.
