2-1. Plug-in hybrid system
■If the vehicle is not used for a long time
●The 12-volt battery may discharge. In this event, charge the 12-volt battery.
(P. 607)
In order to prevent the hybrid battery (traction battery) from becoming
extremely low in charge, charge the hybrid battery (traction battery) from
external power source or start the hybrid system at least once every 2 or 3
months, and turn the power switch off after the gasoline engine has
stopped automatically. (If the gasoline engine does not start up even after
approximately 10 seconds have passed since the “READY” indicator came
on, the power switch can be turned to off without any further action.)
●When the vehicle is left with the charging cable connected, the electricity
consumption amount of the 12-volt battery increases due to controls, such
as the system checking, operating. When the charging cable is not needed,
immediately remove it from the vehicle.
■Sounds and vibrations specific to a hybrid vehicle
There may be no engine sound or vibration even though the vehicle is able to
move with the “READY” indicator is illuminated. For safety, apply the parking
brake and make sure to shift the shift position to P when parked.
The following sounds or vibrations may occur when the hybrid system is
operating and are not a malfunction.
●Motor sounds may be heard from the engine compartment.
●Sounds may be heard from the hybrid battery (traction battery) when the
hybrid system starts or stops.
●Relay operating sounds such as a snap or soft clank will be emitted from the
hybrid battery (traction battery), behind the rear seats, when the hybrid sys-
tem is started or stopped.
●Sounds from the hybrid system may be heard when the back door is open.
●Sounds may be heard from the transmission when the gasoline engine
starts or stops, when driving at low speeds, or during idling.
●Engine sounds may be heard when accelerating sharply.
●Sounds may be heard due to regenerative braking when the brake pedal is
depressed or as the accelerator pedal is released.
●Vibration may be felt when the gasoline engine starts or stops.
●Cooling fan sounds may be heard from the air intake vents. (P. 99)
■Vehicle proximity notification system
In the following cases, the vehicle proximity notification system may be diffi-
cult for surrounding people to hear.
●In very noisy areas
●In the wind or the rain
Also, as the vehicle proximity notification system is installed on the front of
the vehicle, it may be more difficult to hear from the rear of the vehicle com-
pared to the front.

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-temperature 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. 667)
●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.

2-2. Charging
Before charging, always check the following items.
●The parking brake is applied. (P. 352)
●The headlights are switched off or set to AUTO, and lights such as
the emergency flashers and interior lights etc. are switched off.
If these light switches are turned ON, then these features will consume
electricity, and charging time will increase.
●The power switch is off. (P. 3 3 8 )
Before charging, make sure that each part of the charging cable is in
good condition. (P. 120)
■Safety functions
●The hybrid system will not start while the charging cable is attached to the
vehicle, even if the power switch is operated.
●If the charging cable is connected while the “READY” indicator is illumi-
nated, the hybrid system will stop automatically and driving will not be possi-
ble.
●When the charging cable is connected to the vehicle, the shift position can-
not be changed from P to another position.
■During charging
The followings occur, however, it does not indicate a malfunction.
●The charging starting time may differ depending on the state of the vehicle.
●During charging, the sound of the fan may be heard from the onboard trac-
tion battery charger cooling air intake vents. (P. 145)
●During and after charging, the rear seat and its surrounding area in which
