■Hybrid battery (traction battery)
charge mode
●The following may occur to protect the system, etc.
• Cannot switch to hybrid battery (traction battery) charge mode or
cannot cancel it
• Gasoline engine does not start or stops even after switching to
hybrid battery (traction battery)
charge mode
●If a load to the system is large,
such as when the power con-
sumption of the air conditioning
system is large or when the tem-
perature of the engine coolant is
high, it may take longer time than
usual to charge using the hybrid
battery (traction battery) charge
mode, or charging to the hybrid

WARNING
■When using the hybrid bat-
tery (traction battery) charge
mode
Observe the following precautions
when using the hybrid battery
(traction battery) charge mode
while parking.
Failure to do so may lead to death
or serious health hazard, as the
gasoline engine operates when in
the hybrid battery (traction bat-
tery) charge mode.
●Do not stop the vehicle near
flammable materials.
●Do not use the hybrid battery
(traction battery) charge mode

■Running out of fuel
When the vehicle has run out of fuel
and the hybrid system cannot be
started, refuel th e vehicle with at
least enough gasoline to make the
low fuel level warning light ( P.518)
go off. If there is only a small
amount of fuel, th e hybrid system
may not be able to start. (The stan-
dard amount of fuel is about 2.3 gal.
[8.8 L, 1.9 Imp.gal.], when the vehi-
cle is on a level surface. This value
may vary when the vehicle is on a
slope. Add extra fuel when the vehi-
cle is inclined.)
■Electromagnetic waves
●High voltage parts and cables on
the hybrid vehicles incorporate
electromagnetic shielding, and
therefore emit approximately the
same amount of electromagnetic
waves as conventional gasoline
powered vehicles or home elec-
tronic appliances.
●Your vehicle may cause sound
interference in so me third party-
produced radio parts.
■Effect of magnetic forces
If objects that generate strong mag-
netic forces, such as large speak-
ers, are placed inside the luggage
compartment or installed nearby,
the generated magnetic forces may
negatively affect t he hybrid system.
■Hybrid battery (traction battery)
(lithium-ion battery)
The hybrid battery (traction battery)
has a limited service life.
The hybrid battery (traction battery)
capacity (the ability to hold a
charge) reduces with time and use
in the same way as other recharge-
able batteries. The extent at which capacity reduces changes drasti-
cally depending on the environment
(ambient temperature, etc.) and
usage conditions, such as how the
vehicle is driven and how the hybrid
battery (traction battery) is charged.
This is a natural characteristic of
lithium-ion batteries, and is not a
malfunction. Also, even though the
EV driving range becomes shorter
when the hybrid battery (traction
battery) capacity reduces, vehicle
performance does not significantly
become worse.
In order to reduce t
he possibility of
the capacity reducing, follow the
directions listed on P.121, “Capacity
reduction of the hybrid battery (trac-
tion battery)”.
■Starting the hybrid system in an
extremely cold environment
When the hybrid battery (traction
battery) is extremely cold (below
approximately -22°F [-30°C]) under
the influence of the outside tem-
perature, it may n ot be possible to
start the hybrid system. In this case,
try to start the hybrid system again
after the temperature of the hybrid
battery increases due to the outside
temperature increase etc.

WARNING
■High voltage precautions
The vehicle has high voltage DC
and AC systems as well as a 12-
volt system. DC and AC high volt-
age is very dangerous and can
cause severe burns and electric
shock that may result in death or
serious injury.

892-1. Plug-in hybrid system

Plug-in hybrid system
WARNING
●Never touch, disassemble,
remove or replace the high volt-
age parts, cables or their con-
nectors.
●The hybrid system will become
hot after starting as the system
uses high voltage. Be careful of
both the high voltage and the
high temperature, and always
obey the caution labels
attached to the vehicle.
●Never try to open the service
plug access hole located in the
luggage compartment. The ser-
vice plug is used only when the
vehicle is servi ced and is sub-
ject to high voltage.
■Road accident cautions
Observe the following precautions
to reduce the risk of death or seri-
ous injury:
●Pull your vehicle off the road,
apply the parking brake, shift
the shift lever 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 bat-
tery) is damaged, the internal
construction of the battery will
prevent a large amount of elec-
trolyte from l eaking out. How-
ever, 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.507)

902-1. Plug-in hybrid system
WARNING
●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.
■Hybrid battery (traction bat-
tery)
●Your vehicle contains a sealed
lithium-ion battery.
●Never resell, hand over or mod-
ify the hybrid battery. To prevent
accidents, hybrid batteries that
have been removed from a dis-
posed vehicle are collected
through Toyota dealer. Do not
dispose of the battery yourself.
Unless the battery is properly
collected, the following may
occur, resulting in death or seri-
ous injury:
• The hybrid battery may be ille- gally disposed of or dumped,
and it is hazardous to the envi-
ronment 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 bat-
tery is used outside of your
vehicle or modifi ed 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 accident 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 hav-
ing 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 bat-
tery must be disposed of by
your Toyota dealer or a qualified
service shop. If the hybrid bat-
tery is not disposed of properly,
it may cause electric shock that
can result in dea th or serious
injury.
■Caution while driving
If the vehicle under floor area
receives strong shock or impact
while driving, stop the vehicle in a
safe area and check around the
bottom of the vehicle. If there is
damage to the hybrid battery
(traction battery) or liquid leakage,
it may lead to a v ehicle fire, etc.
Do not touch the vehicle and
immediately contact your Toyota
dealer.
■Modifications
Do not modify the vehicle to make
the height lower.
It is easier for the hybrid battery
(traction battery) in the under floor
area to come in contact with the
ground when the vehicle is low-
ered. If the hybrid battery (traction
battery) is damaged, a vehicle fire
may occur which could lead to
death or serious injury.

922-1. Plug-in hybrid system
detected by the impact sensor,
the emergency shut off system
blocks off the high voltage cur-
rent and stops the fuel pump to
minimize the risk of electrocu-
tion and fuel leakage.
If the emergency shut off system
activates, your vehicle will not
restart. To restart the hybrid sys-
tem, contact your Toyota dealer.
A message is automatically dis-
played when a malfunction
occurs in the hybrid system or
an improper operation is
attempted.
If a warning message is shown
on the multi-information display,
read the message and follow the
instructions.
■If a warning light comes on, a
warning message is displayed
or the 12-volt battery is discon-
nected
The hybrid system may not start. In
that case, try to start the system
again. If the “READY” indicator does
not come on, contact your Toyota
dealer.
Primarily using EV mode and
AUTO EV/HV mode when driv-
ing in cities and using HV mode
when driving on highways (or
freeways) can help conserve
fuel and electricity. ( P.78)
When using Eco drive mode, the
torque corresponding to the
accelerator pedal depression
amount can be generated more
smoothly than it is in normal
conditions. In addition, the oper-
ation of the air conditioning sys-
tem (heating/cooling) will be
minimized, improving fuel and
electricity economy. ( P.377)
Eco-friendly driving is possible
by keeping the Hybrid System
Indicator within Eco area.
