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 Toy-
ota dealer for precautionary
measures or special instructions
regarding installation of a mobile
two-way radio system.
High voltage parts and cables on the hybrid vehicles emit
approximately the same amount
of electromagnetic waves as the
conventional gasoline powered
vehicles or home electronic
appliances despite of their elec-
tromagnetic 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 comput-
ers
*1
Certain data, such as the following,
is recorded dependi ng on the oper-
ation timing and status of each
function.
• Basic vehicle behavior related data (engine speed/electric motor
speed, accelerator/brake pedal
operation, vehicle speed, etc.)
• Operating state of the driving support systems (recorded during
system operation, includes basic
vehicle behavior related data)
• Driving support system sensor data
• Image data (images from the front, rear and side cameras)

Vehicle data recording

301-1. For safe use
based on US motor vehicle safety standards (FMVSS208). The air-
bag sensor assembly (ECU) controls airbag deployment based on
information obtained from the sensors, etc., shown in the system
components diagram above. This in formation includes crash sever-
ity and occupant information. As the airbags deploy, a chemical
reaction in the inflators quickly fills the airbags with non-toxic gas to
help restrain the motion of the occupants.
■If the SRS airbags deploy
(inflate)
●Slight abrasions, burns, bruising,
etc., may be sustained from SRS
airbags, due to the extremely high
speed of deployment (inflation) by
hot gases.
●A loud noise and white powder will
be emitted.
●Parts of the airbag module (steer-
ing wheel hub, airbag cover and
inflator) as well as the parts
around the airbags may be hot for
several minutes. T he airbag itself
may also be hot.
●The windshield may crack.
●The hybrid system will be stopped
and fuel supply to the engine will
be stopped. ( P. 7 4 )
●All of the doors will be unlocked.
( P.116)
●The brakes and st op lights will be
controlled automatically. ( P.285)
●The interior lights will turn on auto-
matically. ( P.309)
●The emergency flashers will turn
on automatically. ( P.394)
●For Safety Connect subscribers, if
any of the following situations
occur, the system is designed to
send an emergency call to the
response center, notifying them of
the vehicle’s location (without
needing to push the “SOS” button)
and an agent will attempt to speak
with the occupants to ascertain
the level of emergency and assis-
tance required. If the occupants
are unable to communicate, the agent automatically treats the call
as an emergency and helps to dis-
patch the necessary emergency
services. (
P. 6 4 )
• When an SRS airbag has been deployed
• When a seat belt pretensioner has
operated
• When the vehicle has been involved in a severe rear-end colli-
sion
■The SRS airbags deploy in a
frontal impact when
●The following SRS airbags will
deploy in the event of an impact
that exceeds a th reshold level
(level of force corresponding to an
approximately 12 - 18 mph [20 -
30 km/h] frontal collision with a
fixed wall that does not move or
deform):
• SRS front airbags
• SRS knee airbag
●The threshold level at which the
SRS airbags will deploy will be
higher than normal in the in the
following situations:
• When the vehicle collides with an
object, such as a parked vehicle
or sign pole, which moves or
deforms on impact
• If the vehicle is involved in an underride collision, such as a colli-
sion in which the front of the vehi-
cle “underrides”, or goes under,
the bed of a truck
●Depending on the type of collision,
only the following may deploy:
• Seat belt pretensioners
●The SRS airbags for the front pas-
senger’s seat will not deploy if
there is no passe nger in the front

States, Toyotapr.com in Puerto
Rico and Toyota.ca in Canada.
Important! Read this informa-
tion before using Safety Con-
nect.
■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.

■System components
The illustration is an example for explanation and may differ from the actual
item.
Gasoline engine
Electric motor (traction motor)
Rear electric motor (traction motor)
■When stopped/during start
off
The gasoline engine stops
*
when the vehicle is stopped.
During start off, the electric motor (traction motor) drives the
vehicle. At slow speeds or when
traveling down a gentle slope,
the engine is stopped* and the
electric motor (traction motor) is
used.
Hybrid system features
Your vehicle is a hybrid vehicle. It has characteristics differ ent
from conventional vehicles. Be sure you are closely familiar
with the characteristics of your vehicle, and operate it with
care.
The hybrid system combines the use of a gasoline engine and
an electric motor (traction motor) according to driving condi-
tions, improving fuel efficiency and reducing exhaust emis-
sions.
System components

691-4. Hybrid system

For safety and security
When the shift lever is in N, the
hybrid battery (traction battery)
is not being charged.
*: When the hybrid battery (traction battery) requires charging or the
engine is warming up, etc., the
gasoline engine will not automati-
cally stop. ( P. 6 9 )
■During normal driving
The gasoline engine is predomi-
nantly used. The electric motor
(traction motor) charges the
hybrid battery (traction battery)
as necessary.
■When accelerating sharply
When the accelerator pedal is
depressed heavily, the power of
the hybrid battery (traction bat-
tery) is added to that of the gas-
oline engine via the electric
motor (traction motor).
■When braking (regenera-
tive braking)
The wheels operate the electric
motor (traction motor) as a
power generator, and the hybrid
battery (traction battery) is
charged.
■Regenerative braking
In the following si tuations, kinetic
energy is converted to electric
energy and deceleration force can
be obtained in conjunction with the
recharging of the hybrid battery
(traction battery).
●The accelerator pedal is released
while driving with the shift lever in
D or B.
●The brake pedal is depressed
while driving with the shift lever in D or B.
■EV indicator
The EV indicator comes on when
the vehicle is driven using only the
electric motor (traction motor) or the
gasoline engine is stopped.
■Conditions in which the gaso-
line engine may not stop
The gasoline engine starts and
stops automatically. However, it may
not stop automatic ally in the follow-
ing conditions:
●During gasoline engine warm-up
●During hybrid battery (traction bat-
tery) charging
●When the temperature of the
hybrid battery (traction battery) is
high or low
●When the heater is switched on
Depending on the circumstances,
the gasoline engine may also not
stop automatically in other situa-
tions.
■Charging the hybrid battery
(traction battery)
As the gasoline engine charges the
hybrid battery (trac tion battery), the
battery does not need to be charged
from an outside source. However, if
the vehicle is left parked for a long
time the hybrid battery (traction bat-
tery) will slowly dis charge. For this
reason, be sure to drive the vehicle
at least once every few months for
at least 30 minutes or 10 miles (16
km). If the hybrid battery (traction
battery) becomes fully discharged
and you are unabl e to start the
hybrid system, contact your Toyota
dealer.

■Charging the 12-volt battery
 P. 4 3 5
■After the 12-volt battery has dis-
charged or when the terminal
has been removed and installed
during exchange, etc.
The gasoline engine may not stop
even if the vehicle is being driven by
the hybrid battery (traction battery).
If this continues for a few days, con-
tact your Toyota dealer.
■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” indi-
cator is illuminated. For safety, apply
the parking brake and make sure to
shift the shift lever to P when
parked.
The following sounds or vibrations
may occur when the hybrid system
is operating and are not a malfunc-
tion:
●Motor sounds may be heard from
the engine compartment.
●Sounds may be heard from the
hybrid battery (traction battery)
under the rear seats 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), under the rear seats,
when the hybrid system 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 driv-
ing 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 dep ressed 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 vent on the side
of the lower part of the rear left
seat.
■Maintenance, repair, recycling,
and disposal
Contact your Toyota dealer regard-
ing maintenance, repair, recycling
and disposal. Do n ot dispose of the
vehicle yourself.
■Customization
Some functions can be customized.
(  P.463)
When driving with the gasoline
engine stopped, a sound, which
changes in accordance with the
driving speed, will be played in
order to warn people nearby of
the vehicle’s approach. The
sound will stop when the vehicle
speed exceeds approximately
22 mph (35 km/h).
■Vehicle proximity notification
system
In the following ca ses, the vehicle
proximity notification system may be
difficult for surrounding people to
hear.
●In very noisy areas
●In the wind or the rain
Also, as the vehicle proximity notifi-
cation system is installed on the
front of the vehicle, it may be more
difficult to hear fr om the rear of the
vehicle compared to the front.
