Please note that this manual applies to
all models and explains all equipment,
including options. Therefore, you may
find explanations for equipment not
installed on your vehicle and the illus-
trations used may differ from your vehi-
cle.
All specifications provided in this man-
ual are current at the time of printing.
Over time, your vehicle may receive
updates that modify the vehicle and
make material in this manual incom-
plete and/or inaccurate. Because of
Lexus’ interest in continual product
improvement, Lexus reserves the right
to make changes to this manual at any
time without notice.
If Lexus chooses to update the manual,
updated versions can be viewed by
selecting your vehicle by model and
year at the following URL or on your
mobile device if you have access to the
Lexus app.
https://drivers.lexus.com
Approximately five hours after the
engine is turned off, you may hear
sound coming from under the vehicle
for several minutes. This is the sound of
a fuel evaporation leakage check and,
it does not indicate a malfunction.
A wide variety of non-genuine spare
parts and accessories for Lexus vehi-
cles are currently available in the mar-
ket. You should know that Toyota does
not warrant these products and is not
responsible for their performance,
repair, or replacement, or for any dam-
age they may cause to, or adverse
effect they may have on, your Lexus
vehicle.
This vehicle should not be modified
with non-genuine Lexus products.
Modification with non-genuine Lexus
products could affect its performance,
safety or durability, and may even vio-
late governmental regulations. In addi-
tion, damage or performance
problems resulting from the modifica-
tion may not be covered under war-
ranty.
Also, remodeling like this will have an
effect on advanced safety equipment
such as Lexus Safety System + 3 and
there is a danger that it will not 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 information.
Lexus does not make any guarantees

for problems caused by installing
non-genuine Lexus products.
The installation of a mobile two-way
radio system in your vehicle could
affect electronic systems such as:
Multiport fuel injection sys-
tem/sequential multiport fuel injec-
tion system
Lexus Safety System + 3
Anti-lock brake system
SRS airbag system
Seat belt pretensioner system
Be sure to check with your Lexus
dealer for precautionary measures or
special instructions regarding installa-
tion of a mobile two-way radio system.
This vehicle is equipped with sophisti-
cated computers that record certain
data regarding vehicle controls and
operations.
■Data recorded by the computers*1
*1: The recorded data varies according to
the vehicle grade level and options with
which it is equipped.
Certain data, such as the following, is
recorded depending on the operation
timing and status of each function.
Basic vehicle behavior related data
(engine speed, accelerator/brake
pedal operation, vehicle speed, etc.)
Operating state of the driving sup-
port systems (recorded during sys-
tem operation, includes basic
vehicle behavior related data)
Driving support system sensor data
Image data (images from the front,
rear, vehicle periphery, and driver
monitor cameras)*2
*2: The vehicle has multiple cameras. For
details on from which cameras images
are recorded, contact your Lexus
dealer.
Location information
These computers do not record conversa-
tions, sounds, or images of the inside of the
vehicle.
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 per-
sonal information by the Lexus
Safety System + 3
The operating state of each system,
data from each sensor, image data
(images from the front/rear cameras),
andposition information is recordedby
the Lexus Safety System + 3 in the fol-
lowing situations. Toyota obtains this
information when the vehicle is
brought to the dealership or when sent
to the Toyota servers.
In certain collisions or collision-like
situations
When driving on roads with certain
traffic situations, such as congestion,
poor road surfaces, poor weather,
etc.
When driving on certain roads, such

as roads which were recently
opened or extended
After the engine is started, for a cer-
tain amount of time
To learn more about the vehicle data
collected, used and shared by Lexus,
please visit http://www.lexus.com/pri-
vacyvts/.
■Data provision and use purpose by
third parties
Data recorded by the computers may
be used for collision analysis, malfunc-
tion diagnosis, automated driving,
advanced safety and map related tech-
nologies (technology, product devel-
opment, product improvement, etc.)
and products and services which use
data (maps used for automated driving
and advanced safety technologies,
driving condition analysis, analysis of
the driving environment, such as road
infrastructure, traffic condition com-
munication, etc. Herein referred to as
“individual services”.) Also, this data
may be used for customer support
related to a collision, collision analysis
or resolution.
In situations such as the following, Toy-
ota may disclose the recorded data to
a third party:
When the consent of the vehicle
owner (or the lessee if the vehicle is
leased) has been given
When officially requested by the
police, a court of law or a govern-
ment agency
When it is to be used by Toyota in a
lawsuit
• When data is to be used research pur-
poses after processing so that the data is
not tied to a specific vehicle or vehicle
owner
In addition to the above, Toyota may dis-
close the data recorded by the Lexus
Safety System + 3 to a third party in the fol-
lowing situations:
When separate consent of the vehi-
cle owner (or the lessee if the vehi-
cle is leased) has been given. This
includes situations when the user
subscribes to an individual service
which is provided by a second party
and uses vehicle 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 autonomous driving soft-
ware, etc. for the purpose of
research and development (tech-
nology, product development, prod-
uctimprovement, etc.)ofautomated
driving, advanced safety and map
related technologies
When providing image data and
position information to a company
involved in map creation, etc. for the
purpose of research and develop-
ment map related technologies
When providing image data and
position information to a local gov-
ernment for the purpose of road
maintenance, etc.
When providing processed image
data and position information to
traffic condition communication
individual services

9
When providing image data from
near a fire, or other area that emer-
gency services are dispatched, to
the fire department of a local gov-
ernment which has entered a sepa-
rate contract with Lexus
Image information recorded by the vehicle
can be erased by your Lexus dealer.
The image recording function can be dis-
abled. However, if the function is disabled,
data from when systems operate will not be
available.
If you wish to stop the collection of Lexus
Safety System + 3 data by the Toyota serv-
ers for the purpose of research and devel-
opment and provision to individual services,
contact your Lexus dealer.
This vehicle is equipped with an event
data recorder (EDR). The main pur-
pose of an EDR is to record, in certain
crashor near crash-likesituations,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 dynam-
ics and safety systems for a short
period of time, typically 30 seconds 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 pas-
senger safety belts were buck-
led/fastened;
• How far (if at all) the driver was
depressing the accelerator and/or
brake pedal; and,
• How fast the vehicle was traveling.
These data can help provide a better
understanding of the circumstances in
which crashes and injuries occur.
NOTE:EDRdataarerecordedbyyour
vehicle only if a non-trivial crash situa-
tion occurs; no data are recorded by
the EDR under normal driving condi-
tions and no personal data (e.g., name,
gender, age, and crash location) are
recorded.However,otherparties,such
aslaw enforcement, could combinethe
EDR data with the type of personally
identifying data routinely acquired
during a crash investigation.
To read data recorded by an EDR, spe-
cial equipment is required, and access
to the vehicle or the EDR is needed. In
addition to the vehicle manufacturer,
other parties, such as law enforcement,
that have the special equipment, can
read the information if they have
access to the vehicle or the EDR.
Disclosure of the EDR data
Lexus will not disclose the data recorded in
an EDR to a third party except when:
• An agreement from the vehicle’s owner
(or the lessee for a leased vehicle) is
obtained
• In response to an official request by the
police, a court of law or a government
agency
• For use by Lexus in a lawsuit
However, if necessary, Lexus may:
• Use the data for research on vehicle
safety performance
• Disclose the data to a third party for
Event data recorder

research purposes without disclosing
information about the specific vehicle or
vehicle owner
The SRS airbag and seat belt preten-
sioner devices in your Lexus contain
explosive chemicals. If the vehicle is
scrapped with the airbags and seat belt
pretensioners left as they are, this may
cause an accident such as fire. Be sure
to have the systems of the SRS airbag
and seat belt pretensioner removed
and disposed of by a qualified service
shop or by your Lexus dealer before
you scrap your vehicle.
Special handling may apply, See
www.dtsc.ca.gov/hazard-
ouswaste/perchlorate.
Your vehicle has components that may
contain perchlorate. These compo-
nents may include the airbags, seat belt
pretensioners, wireless remote control
batteries, and the batteries in the tire
pressure warning valve and transmit-
ters.

WARNING
■General precautions while driving
Driving under the influence: Never drive
your vehicle when under the influence of
alcohol or drugs that have impaired your
ability to operate your vehicle. Alcohol
and certain drugs delay reaction time,
impair judgment and reduce coordina-
tion, which could lead to an accident that
could result in death or serious injury.
Defensive driving: Always drive defen-
sively. Anticipate mistakes that other
drivers or pedestrians might make and
be ready to avoid accidents.
Driver distraction: Always give your full
attention to driving. Anything that dis-
tracts the driver, such as adjusting con-
trols, talking on a cellular phone or
reading can result in a collision with
resulting death or serious injury to you,
your occupants or others.
■General precaution regarding chil-
dren’s safety
Never leave children unattended in the
vehicle, and never allow children to have
or use the key.
Children may be able to start the vehicle
or shift the vehicle into neutral. There is
also a danger that children may injure
themselves by playing with the windows,
the moon roof or panoramic moon roof,
or other features of the vehicle. In addi-
tion, heat build-up or extremely cold
temperatures inside the vehicle can be
fatal to children.
