work properly or the danger that
it may work in situations where it
should not be working.
Installing electronic devices and
radios increases the risk of
cyber attacks through the
installed parts, which may lead
to unexpected accidents and
leakage of personal informa-
tion. Toyota does not make any
guarantees for problems caused
by installing non-genuine Toyota
products.
The installation of a mobile two-
way radio system in your vehicle
could affect electronic systems
such as:
Hybrid system
 Multiport fuel injection sys-
tem/sequential multiport fuel
injection system
 Toyota Safety Sense 3.0
 Anti-lock brake system
 SRS airbag system
 Seat belt pretensioner system
Be sure to check with your
Toyota dealer for precautionary
measures or special instructions
regarding installation of a mobile
two-way radio system.
High voltage parts and cables on the Hybrid Electric Vehicles
emit approximately the same
amount of electromagnetic
waves as the conventional gas-
oline powered vehicles or home
electronic appliances despite of
their electromagnetic shielding.
Unwanted noise may occur in
the reception of the mobile two-
way radio.
This vehicle is equipped with
sophisticated computers that
record certain data regarding
vehicle controls and operations.
■Data recorded by the com-
puters

■Exposure to radio fre-
quency signals
The Safety Connect system
installed in your vehicle is a low-
power radio transmitter and
receiver. It receives and also
sends out radio frequency (RF)
signals.
In August 1996, the Federal
Communications Commission
(FCC) adopted RF exposure
guidelines with safety levels for mobile wireless phones. Those
guidelines are consistent with
the safety standards previously
set by the following U.S. and
international standards bodies.

ANSI (American National
Standards Institute) C95.1
[1992]
 NCRP (National Council on
Radiation Protection and
Measurement) Report 86
[1986]
 ICNIRP (International Com-
mission on Non-Ionizing Radi-
ation Protection) [1996]
Those standards were based on
comprehensive and periodic
evaluations of the relevant sci-
entific literature. Over 120 scien-
tists, engineers, and physicians
from universities, and govern-
ment health agencies and
industries reviewed the avail-
able body of research to
develop the ANSI Standard
(C95.1).
The design of Safety Connect
complies with the FCC guide-
lines in addition to those stan-
dards.

842-1. Plug-in hybrid system
■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.562)
go off. If there is only a small
amount of fuel, the hybrid system
may not be able to start. (The stan-
dard amount of fuel is about 2.1 gal.
[8.0 L, 1.8 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 Plug-in Hybrid Electric Vehi-
cles incorporate electromagnetic
shielding, and therefore emit
approximately the same amount
of electromagnetic waves as con-
ventional gasoline powered vehi-
cles or home electronic
appliances.
●Your vehicle may cause sound
interference in some 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 the 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 the possibility of
the capacity reducing, follow the
directions listed on P.113, “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 not 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.
●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.

1132-2. Charging
2
Plug-in hybrid system
■Safety functions
●The hybrid system will not start
while the AC charging cable is
attached to the vehicle, even if the
power switch is operated.
●If the AC charging cable is con-
nected while the “READY” indica-
tor is illuminated, the hybrid
system will stop automatically and
driving will not be possible.
■During charging
●The charging starting time may
differ depending on the state of
the vehicle, but this does not indi-
cate a malfunction.
●Cooling fan sounds may be heard
from near the luggage compart-
ment.
●During charging, sounds may be
heard from near the hybrid battery
(traction battery) in accordance
with the operation of the air condi-
tioning system or “Battery Cooler”.
●During and after charging, the lug-
gage compartment and its sur-
rounding area in which the
onboard traction battery charger is
installed may get warm.
●The surface of the CCID
(Charging Circuit Interrupting
Device) may become hot, but this
does not indicate a malfunction.
●Depending on radio wave condi-
tions, interference may be heard
on the radio.
■When charging using a public
charging facility
When charging using a public charging facility, check the setting of
the charging schedule function.
●When the charging schedule is
registered, temporarily turn off the
function or turn “Charge Now” on.
(
 P.128, 132)
●When the charging schedule is set
to on, charging will not start even
if the AC charging cable is con-
nected. Also, charging fee may
occur due to connection of the AC
charging cable.
■Using a DC Charger
DC Chargers cannot be used with
this vehicle.
■Capacity reduction of the
hybrid battery (traction battery)
The capacity of the hybrid battery
(traction battery) will decline gradu-
ally when the hybrid battery (traction
battery) is in use. The rate at which
it declines will diff er in accordance
with environmental conditions and
the way in which the vehicle is used.
Observing the following can help
suppress battery capacity decline.
●Avoid parking the vehicle in areas
with a high temperature under
direct sunlight when the hybrid
battery (traction battery) is fully
charged.
●Avoid accelerating and decelerat-
ing frequently and suddenly when
EV driving.
●Avoid frequent driving near the top
speed for EV driving. ( P.79)
●Leave a low level of charge in the
hybrid battery (traction battery)
when leaving the vehicle undriven
for a long period of time.
After confirming that EV mode or
AUTO EV/HV mode has switched
to HV mode, turn the power switch
off.
●Use the charging schedule func-
tion as much as possible in order
to fully charge t he hybrid battery
(traction battery) immediately
before starting off. ( P.123)
Things to know before

■When riding in an aircraft
When bringing an electronic key
onto an aircraft, make sure you do
not press any buttons on the elec-
tronic key while inside the aircraft
cabin. If you are carrying an elec-
tronic key in your bag etc., ensure
that the buttons are not likely to be
pressed accidentally. Pressing a
button may cause the electronic key
to emit radio waves that could inter-
fere with the oper ation of the air-
craft.
■Electronic key battery depletion
●The standard battery life is 1 to 2
years.
●If the battery becomes low, an
alarm will sound in the cabin and a
message will be displayed on the
multi-information display when the hybrid system stops.
●To reduce key ba
ttery depletion
when the electronic key is to not
be used for long periods of time,
set the electronic key to the bat-
tery-saving mode. ( P.205)
●As the electronic key always
receives radio waves, the battery
will become depleted even if the
electronic key is not used. The fol-
lowing symptoms indicate that the
electronic key battery may be
depleted. Replace the battery
when necessary.
• The smart key system or the wire- less remote control does not oper-
ate.
• The detection area becomes smaller.
• The LED indicator on the key sur- face does not turn on.
You can replace the battery by your-
self ( P.538). However, as there is
a danger that the electronic key may
be damaged, it is recommended
that replacement is carried out by
your Toyota dealer.
●To avoid serious deterioration, do
not leave the electronic key within
3 ft. (1 m) of the following electri-
cal appliances that produce a
magnetic field:
•TVs
• Personal computers
• Cellular phones, cordless phones and battery chargers
• Table lamps
• Induction cookers
●If the electronic key is near the
vehicle for longer than necessary,
even if the smart key system is not
operated, the key battery may
become depleted faster than nor-
mal. When not operating the
smart key system, it is recom-
mended to not stay with the elec-
tronic key near the vehicle longer
than necessary.
