Please note that this manual applies to
all models and explains all equipment,
including options. Therefore, you may
find some explanations for equipment
not installed on your vehicle.
All specifications provided in this man-
ual are current at the time of printing.
However, because of the Lexus policy
of continual product improvement, we
reserve the right to make changes at
any time without notice.
Depending on specifications, the vehi-
cle shown in the illustrations may differ
from your vehicle in terms of color and
equipment.
Approximately five hours after the
hybrid system 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 mal-
function.
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.
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 injec-
tion system
 Lexus Safety System + 2.0
 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.
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 electro-
magnetic shielding.
Unwanted noise may occur in the
reception of the mobile two-way radio.
The vehicle is equipped with sophisti-
cated computers that will record cer-
tain data, such as:
• Engine speed/Electric motor speed
(traction motor speed)
• Accelerator status
•Brake status
• Vehicle speed
• Operation status of the driving assist systems
• Images from the cameras
Your vehicle is equipped with cameras.
Contact your Lexus dealer for the location
of recording cameras.
The recorded data varies according to
the vehicle grade level and options
with which it is equipped.
These computers do not record con-
versations or sounds, and only record
images outside of the vehicle in certain
situations.
 Data Transmission
Your vehicle may transmit the data
recorded in these computers to Lexus
without notification to you.
Data usage
Lexus may use the data recorded in this
computer to diagnose malfunctions, con-
duct research and development, and
improve quality. Lexus will not disclose the recorded data to
a third party except:
• With the consent of the vehicle owner or
with the consent of the lessee if the vehi-
cle is leased
• In response to an official request by the police, a court of law or a government
agency
• For use by Lexus in a lawsuit
• For research purposes where the data is not tied to a specific vehicle or vehicle
owner
 Recorded image information can be
erased by your Lexus dealer.
The image recording function can be dis-
abled. However, if the function is disabled,
data from when the system operates will
not be available.

LEXUS NX300h Owners Manual_USA_M78578_en
This vehicle is equipped with an event
data recorder (EDR). The main pur-
pose 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 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: EDR data are recorded by your
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, other parties, such
as law enforcement, could combine the
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 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.

WARNING
■General precautions while driving
Driving under the infl uence: Never drive
your vehicle when un der 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 other features of the
vehicle. In addition, heat build-up or
extremely cold temperatures inside the
vehicle can be fatal to children.
