al_USA_OM78212U Please note that this manual applies to
all models and explains all equipment,
including options. Therefore, you may
find some explanat ions 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 system/
sequential multiport fuel injection
system
 Lexus Safety System+
 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 For your information Main Owner’s Manual

al_USA_OM78212U • 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 of ficial 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.
Special handling may apply, See
www.dtsc.ca.gov/hazardouswaste /
perchlorate.
Your vehicle has components that may
contain perchlorate. These compo-
nents may include airbag, seat belt pre-
tensioners, and wireless remote
control batteries. Scrapping of your Lexus

LEXUS NX300h Owners Manu-
al_USA_OM78212U Your vehicle is equipped with ADVANCED AIRBAGS designed based on the US motor
vehicle safety standards (FMVSS208). The airbag sensor assembly (ECU) controls airbag
deployment based on information obtained from the sensors etc. shown in the system com-
ponents diagram above. This in formation includes crash severity and occupant information.
As the airbags deploy, a chemical reaction in the inflators quic kly fills the airbags with non-
toxic gas to help restrain the motion of the occupants. ■
If the SRS airbags deploy (inflate)●
Slight abrasions, burn s, bruising, etc., may
be sustained from SRS airbags, due to the
extremely high speed deployment (infla-
tion) by hot gases.●
A loud noise and white powder will be
emitted.●
Parts of the airbag module (steering
wheel hub, airbag cover and inflator) as
well as the front seat s, parts of the front
and rear pillars, and roof side rails, may
be hot for several minutes. The airbag
itself may also be hot.●
The windshield may crack.●
For Lexus Enform Safety Connect sub-
scribers, if the SRS airbags deploy or in
the event of a severe rear-end collision,
the system is designed to send an emer-
gency call to the response center, notify-
ing them of the vehicl e’s location (without
needing to push the “SOS” button) and
an agent will attempt to speak with the
occupants to ascertain the level of emer-
gency and assistance required. If the
occupants are unable to communicate,
the agent automatically treats the call as
an emergency and help s to dispatch the
necessary emergency services.
( → P.306)
■
SRS airbag deployment conditions (SRS
front airbags)
●
The SRS front airbags will deploy in the
event of an impact that exceeds the set
threshold level (the level of force corre-
sponding to an approximately 12-18 mph
[20-30 km/h] frontal collision with a
fixed wall that does not move or deform).
However, this threshold velocity will be con-
siderably higher in the following situations:
• If the vehicle strikes an object, such as a
parked vehicle or sign pole, which can
move or deform on impact • If the vehicle is involved in an underride
collision, such as a collision in which the
front of the vehicle underrides, or goes
under, the bed of a truck ●
Depending on the type of collision, it is
possible that only the seat belt preten-
sioners will activate. ●
The SRS front airbags for the front pas-
senger will not activate if there is no pas-
senger sitting in the front passenger seat.
However, the SRS front airbags for the
front passenger may deploy if luggage is
put in the seat, even if the seat is unoccu-
pied. ( → P.41)●
The SRS seat cushion airbag on the front
passenger seat will not operate if the
occupant is not wearing a seat belt. ■
SRS airbag deployment conditions (SRS
side and curtain shield airbags) ●
The SRS side and curtain shield airbags
will deploy in the event of an impact that
exceeds the set threshold level (the level
of force corresponding to the impact
force produced by an approximately
3300 lb. [1500 kg] vehicle colliding with
the vehicle cabin from a direction per-
pendicular to the vehicle orientation at an
approximate speed of 12 -18 mph [20 -
30 km/h]). ●
The SRS curtain shield airbags will deploy
in the event of vehicle rollover.
●
The SRS side and curtain shield airbags
may also deploy in the event of a severe
frontal collision.
■
Conditions under which the SRS air-
bags may deploy (inflate), other than a
collision
The SRS front airbags and SRS side and
curtain shield airbags may also deploy if a
serious impact occurs to the underside of
your vehicle. Some examples are shown in
the illustration.
