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
*1
*1: The recorded data varies
according to the vehicle grade
level and options with which it is
equipped.
Certain data, such as the follow-
ing, is recorded depending on
the operation timing and status
of each function.
 Basic vehicle behavior related
data (engine speed/electric
motor speed, accelera-
tor/brake pedal operation,
vehicle speed, etc.)
 Operating state of the driving
support systems (recorded
during system operation,
includes basic vehicle behav-
ior related data)
 Driving support system sen-

 Image data (images from the
front, rear, vehicle periphery,
and driver monitor cameras)
*2
*2: The vehicle has multiple cam-
eras. For details on from which
cameras images are recorded,
contact your Toyota dealer.
 Location information
These computers do not record
conversations, sounds, or
images of the inside of the vehi-
cle.
Also, personal information which
may be used to identify the
owner of the vehicle (name,
gender, age, etc.) is not
recorded.
■Usage of recorded data and
personal information by the
Toyota Safety Sense 3.0
The operating state of each sys-
tem, data from each sensor,
image data (images from the
front/rear cameras), and posi-
tion information is recorded by
the Toyota Safety Sense 3.0 in
the following situations. Toyota
obtains this information when
the vehicle is brought to the
dealership or when sent to the
Toyota servers.
 In certain collisions or colli-
sion-like situations
 When driving on roads with
certain traffic situations, such
as congestion, poor road sur-
faces, poor weather, etc. 
When driving on certain
roads, such as roads which
were recently opened or
extended
 After the hybrid system is
started, for a certain amount
of time

■Data provision and use pur-
pose by third parties
Data recorded by the computers
may be used for collision analy-
sis, malfunction diagnosis, auto-
mated driving, advanced safety
and map related technologies
(technology, product develop-
ment, product improvement,
etc.) and products and services
which use data (maps used for
automated driving and
advanced safety technologies,
driving condition analysis, analy-
sis of the driving environment,
such as road infrastructure, traf-
fic condition communication,
etc. Herein referred to as “indi-
vidual services”.)
Also, this data may be used for
customer support related to a
collision, collisi on analysis or
resolution.
In situations such as the follow-
ing, Toyota may disclose the
recorded data to a third party:
 When the consent of the vehi-

9
cle owner (or the lessee if the
vehicle is leased) has been
given
 When officially requested by
the police, a court of law or a
government agency
 When it is to be used by
Toyota in a lawsuit
 When data is to be used
research purposes after pro-
cessing so that the data is not
tied to a specific vehicle or
vehicle owner
In addition to the above, Toyota
may disclose the data recorded
by the Toyota Safety Sense 3.0
to a third party in the following
situations:
 When separate consent of the
vehicle owner (or the lessee if
the vehicle is leased) has
been given. This includes sit-
uations when the user sub-
scribes to an individual
service which is provided by a
second party and uses vehi-
cle recorded data, where the
provider has obtained the
user’s consent for providing
data to a third-party
 When providing data to a
company involved in autono-
mous driving software, etc. for
the purpose of research and
development (technology,
product development, prod-
uct improvement, etc.) of
automated driving, advanced safety and map related tech-
nologies
 When providing image data
and position information to a
company involved in map cre-
ation, etc. for the purpose of
research and development
map related technologies
 When providing image data
and position information to a
local government for the pur-
pose of road maintenance,
etc.
 When providing processed
image data and position infor-
mation to traffic condition
communication individual ser-
vices
 When providing image data
from near a fire, or other area
that emergency services are
dispatched, to the fire depart-
ment of a local government
which has entered a separate
contract with Toyota
Image information recorded by the
vehicle can be erased by your
Toyota dealer.
The image recording function can
be disabled. However, if the function
is disabled, data from when systems
operate will not be available.
If you wish to stop the collection of
Toyota Safety Sense 3.0 data by the
Toyota servers for the purpose of
research and development and pro-
vision to individual services, contact
your Toyota dealer.

.
This vehicle is equipped with an
event data recorder (EDR). The
main purpose of an EDR is to
record, in certain crash or near
crash-like situations, such as an
air bag deployment or hitting a
road obstacle, data that will
assist in understanding how a
vehicle’s systems performed.
The EDR is designed to record
data related to vehicle dynamics
and safety systems for a short
period of time, typically 30 sec-
onds or less.
The EDR in this vehicle is
designed to record such data
as:
 How various systems in your
vehicle were operating;
 Whether or not the driver and
passenger safety belts were buckled/fastened;
 How far (if at all) the driver
was depressing the accelera-
tor and/or brake pedal; and,
 How fast the vehicle was trav-
eling.
These data can help provide a
better understanding of the cir-
cumstances in which crashes
and injuries occur.
NOTE: EDR data are recorded
by your vehicle only if a non-triv-
ial crash situation occurs; no
data are recorded by the EDR
under normal driving conditions
and no personal data (e.g.,
name, gender, age, and crash
location) are recorded. How-
ever, other parties, such as law
enforcement, could combine the
EDR data with the type of per-
sonally identifying data rou-
tinely acquired during a crash
investigation.
To read data recorded by an
EDR, special equipment is
required, and access to the
vehicle or the EDR is needed. In
addition to the vehicle manufac-
turer, other parties, such as law
enforcement, that have the spe-
cial equipment, can read the
information if they have access
to the vehicle or the EDR.
 Disclosure of the EDR data
Toyota will not disclose the data
recorded in an EDR to a third party
except when:

Use only floor mats designed
specifically for vehicles of the
same model and model year as
your vehicle. Fix them securely
in place onto the carpet.
1Insert the retaining hooks
(clips) into the floor mat eye-
lets.
2 Turn the upper knob of each
retaining hook (clip) to secure
the floor mats in place.
Always align the marks . The shape of the retaining hooks
(clips) may differ from that shown in
the illustration.
Before driving
Observe the following
before starting off in the
vehicle to ensure safety of
driving.
Installing floor mats
A
WARNING
Observe the following precau-
tions.
Failure to do so may cause the
driver’s floor mat to slip, possibly
interfering with the pedals while
driving. An unexpectedly high
speed may result or it may
become difficult to stop the vehi-
cle. This could lead to an acci-
dent, resulting in death or serious
injury.
■When installing the driver’s
floor mat
●Do not use floor mats designed
for other models or different
model year vehicles, even if
they are Toyota Genuine floor
mats.
●Only use floor mats designed
for the driver’s seat.
●Always install the floor mat
securely using the retaining
hooks (clips) provided.
●Do not use two or more floor
mats on top of each other.
●Do not place the floor mat bot-
tom-side up or upside-down.

301-1. For safe use
Make sure that all occupants are
wearing their seat belts before
driving the vehicle. (P.32)
Use a child restraint system
appropriate for the child until the
child becomes large enough to properly wear the vehicle’s seat
belt. (
P.51)
Make sure that you can see
backward clearly by adjusting
the inside rear view mirror (if
equipped), Digital Rear-view
Mirror (if equipped) and outside
rear view mirrors properly.
( P.216, 217, 225)
WARNING
Observe the following precau-
tions.
Failure to do so may result in
death or serious injury.
●Do not adjust the position of the
driver’s seat while driving.
Doing so could cause the driver
to lose control of the vehicle.
●Do not place a cushion between
the driver or passenger and the
seatback. A cushion may pre-
vent correct posture from being
achieved, and reduce the effec-
tiveness of the seat belt and
head restraint.
●Do not place anything under the
front seats.
Objects placed under the front
seats may become jammed in
the seat tracks and stop the
seat from locking in place. This
may lead to an accident and the
adjustment mechanism may
also be damaged.
●Always observe the legal speed
limit when driving on public
roads.
●When driving over long dis-
tances, take regular breaks
before you start to feel tired.
Also, if you feel tired or sleepy
while driving, do not force your-
self to continue driving and take
a break immediately.

For safety and security
Seat belts
Make sure that all occu-
pants are wearing their seat
belts before driving the
vehicle.
WARNING
Observe the following precautions
to reduce the risk of injury in the
event of sudden braking, sudden
swerving or an accident.
Failure to do so may cause death
or serious injury.
■Wearing a seat belt
●Ensure that all passengers wear
a seat belt.
●Always wear a seat belt prop-
erly.
●Each seat belt should be used
by one person only. Do not use
a seat belt for more than one
person at once, including chil-
dren.
●Toyota recommends that chil-
dren be seated in the rear seat
and always use a seat belt
and/or an appropriate child
restraint system.
●To achieve a proper seating
position, do not recline the seat
more than necessary. The seat
belt is most effective when the
occupants are sitting up straight
and well back in the seats.
●Do not wear the shoulder belt
under your arm.
●Always wear your seat belt low
and snug across your hips.
■Pregnant women
Obtain medical advice and wear
the seat belt in the proper way.
(  P.32)
Women who are pregnant should
position the lap belt as low as
possible over the hips in the same
manner as other occupants,
extending the shoulder belt com-
pletely over the shoulder and
avoiding belt contact with the
rounding of the abdominal area.
If the seat belt is not worn prop-
erly, not only the pregnant
woman, but also the fetus could
suffer death or serious injury as a
result of sudden braking or a colli-
sion.
■People suffering illness
Obtain medical advice and wear
the seat belt in the proper way.
(  P.32)
■When children are in the vehi-
cle
 P.59
■Seat belt damage and wear
●Do not damage the seat belts
by allowing the belt, plate, or
buckle to be jammed in the
door.

321-1. For safe use
Extend the shoulder belt so
that it comes fully over the
shoulder, but does not come
into contact with the neck or
slide off the shoulder. 
Position the lap belt as low as
possible over the hips.
 Adjust the position of the
seatback.
Sit up straight and well back
in the seat.
 Do not twist the seat belt.
■Child seat belt usage
The seat belts of your vehicle were
principally designed for persons of
adult size.
●Use a child restraint system
appropriate for the child, until the
child becomes large enough to
properly wear the vehicle’s seat
belt. ( P.51)
●When the child becomes large
enough to properly wear the vehi-
cle’s seat belt, follow the instruc-
tions regarding seat belt usage.
( P.31)
■Seat belt extender
If your seat belts cannot be fastened
securely because they are not long
enough, a personalized seat belt
extender is available from your
Toyota dealer free of charge.
WARNING
●Inspect the seat belt system
periodically. Check for cuts,
fraying, and loose parts. Do not
use a damaged seat belt until it
is replaced. Damaged seat belts
cannot protect an occupant
from death or serious injury.
●Ensure that the belt and plate
are locked and the belt is not
twisted.
If the seat belt does not function
correctly, immediately contact
your Toyota dealer.
●Replace the seat assembly,
including the belts, if your vehi-
cle has been involved in a seri-
ous accident, even if there is no
obvious damage.
●Do not attempt to install,
remove, modify, disassemble or
dispose of the seat belts. Have
any necessary repairs carried
out by your Toyota dealer. Inap-
propriate handling may lead to
incorrect operation.
Correct use of the seat
belts
WARNING
■Using a seat belt extender
Observe the following precautions
to reduce the risk of injury in the
event of sudden braking, sudden
swerving or an accident.
Failure to do so may cause death
or serious injury.

341-1. For safe use
Move the height adjuster up and
down as needed until you hear a
click.
When the vehicle is subjected to
a severe frontal or side impact
or rollover, the pretensioners
retract the seat belts of the front
seats and rear outer seats to
securely restrain the occupants.
The pretensioners will not operate
in minor frontal or side impacts, or
rear impacts.
■Replacing the belt after the pre-
tensioner has been activated
If the vehicle is in volved in multiple collisions, the pretensioner will acti-
vate for the first collision, but will not
activate for the second or subse-
quent collisions.
■PCS-linked control
If the PCS (Pre-Collision System)
determines that th e possibility of a
collision with a vehicle is high, the
seat belt pretensioners will be pre-
pared to operate.WARNING
■Adjustable shoulder anchor
Always make sure the shoulder
belt is positioned across the cen-
ter of your shoulder. The belt
should be kept away from your
neck, but not falling off your
shoulder. Failure to do so could
reduce the amount of protection in
an accident and cause death or
serious injuries in the event of a
sudden stop, sudden swerve or
accident.
Seat belt pretensioners
(front seats and outboard
rear seats)
WARNING
■Seat belt pretensioners
Observe the following precautions
to reduce the risk of injury in the
event of sudden braking or an
accident.
Failure to do so may result in
death or serious injury.
●Do not place anything, such as
a cushion, on the front passen-
ger’s seat. Doing so will
disperse the passenger’s
weight, which prevents the sen-
sor from detecting the passen-
ger’s weight properly. As a
result, the seat belt pretensioner
for the front passenger’s seat
may not operate in the event of
a collision.
●If a pretensioner has operated,
the SRS warning light will illumi-
nate. In this situation, the seat
belt cannot be used and must
be replaced by your Toyota
dealer.
