For your information
Main Owner’s Manual
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 manual 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 vehicle shown in the illustrations may differ
from your vehicle in terms of color and
equipment.
Noise from under vehicle after turning off the engine
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.
Accessories, spare parts and modification of your Lexus
A wide variety of non-genuine spare
parts and accessories for Lexus vehicles are currently available in the market. 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 violate governmental regulations. In addition, damage or performance
problems resulting from the modification may not be covered under warranty.
Installation of a mobile two-way radio
system
The installation of a mobile two-way
radio system in your vehicle could
affect electronic systems such as:
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 installation of a mobile two-way radio system.
Vehicle data recordings
Your Lexus is equipped with several
sophisticated computers that will
record certain data, such as:
• Engine speed
• Accelerator status
LEXUS NX300 Owners Manual_USA_OM78211U
7
•Brake status
• Vehicle speed
•Shift position
The recorded data varies according to
the vehicle grade level and options
with which it is equipped. These computers do not record conversations 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 these
computers to diagnose malfunctions, conduct 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 vehicle 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
Usage of data collected through
Lexus Enform (U.S. mainland only)
If your Lexus has Lexus Enform and if you
have subscribed to those services, please
refer to the Lexus Enform Telematics Subscription Service Agreement for information on data collected and its usage.
To learn more about the vehicle data
collected, used and shared by
Lexus, please visit www.lexus.com/
privacyvts/.
Event data recorder
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 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 passenger safety belts were buckled/
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 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. However, other parties, such
as law enforcement, could combine the
LEXUS NX300 Owners Manual_USA_OM78211U
8
WARNING
EDR data with the type of personally
identifying data routinely 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 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
Scrapping of your Lexus
The SRS airbag and seat belt pretensioner 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.
Perchlorate Material
Special handling may apply, See
www.dtsc.ca.gov/hazardouswaste/
perchlorate.
Your vehicle has components that may
contain perchlorate. These components may include airbag, seat belt pretensioners, and wireless remote
control batteries.
■ 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 coordination, which could lead to an accident that
could result in death or serious injury.
Defensive driving: Always drive defensively. 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 distracts the driver, such as adjusting controls, talking on a cellular phone or
reading can result in a collision with
resulting death or serious injury to you,
your occupants or others.
LEXUS NX300 Owners Manual_USA_OM78211U
WARNING
■ 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.

WARNING
1-1.For safe use
1-1. For safe use
Before driving
Observe the following before starting off in the vehicle to ensure
safety of driving.
Installing floor mats
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.
1 Insert the retaining hooks (clips)
into the floor mat eyelets.
Observe the following precautions.
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 vehicle. This
could lead to an accident, 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 Lexus 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.

For safe driving
For safe driving, adjust the seat and
mirror to an appropriate position
before driving.
Correct driving posture
Adjust the angle of the seatback so
that you are sitting straight up and
so that you do not have to lean forward to steer. (→P.114)
Adjust the seat so that you can
depress the pedals fully and so that
your arms bend slightly at the
elbow when gripping the steering
wheel. (→P.114, 125)
Lock the head restraint in place
with the center of the head restraint
closest to the top of your ears.
(→P.123)
Wear the seat belt correctly.
(→P.27)
● 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 prevent correct posture from being achieved, and reduce
the effectiveness 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 distances, take
regular breaks before you start to feel
tired. Also, if you feel tired or sleepy
while driving, do not force yourself to
continue driving and take a break
immediately.
Correct use of the seat belts
Make sure that all occupants are wearing their seat belts before driving the
vehicle. (→P.27)
Use a child restraint system appropriate for the child until the child becomes
large enough to properly wear the
vehicle’s seat belt. (→P.46)

For safety and security
Observe the following precautions.
Failure to do so may result in death or
serious injury.

Make sure that you can see the rear of
the vehicle clearly, by adjusting the
inside and outside rear view mirrors
properly. (→P.126, 128)

WARNING
1-1. For safe use
Seat belts
Make sure that all occupants are
wearing their seat belts before driving the vehicle.
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 properly.
● Each seat belt should be used by one
person only. Do not use a seat belt for
more than one person at once, including children.
● Lexus recommends that children be
seated in the rear seat and always use
a seat belt and/or an appropriate child
restraint system.
■ Pregnant women
Obtain medical advice and wear the seat
belt in the proper way. (→P.25)
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
completely over the shoulder and avoiding belt contact with the rounding of the
abdominal area.
If the seat belt is not worn properly, not
only the pregnant woman, but also the
fetus could suffer death or serious injury
as a result of sudden braking or a collision.
● 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.
LEXUS NX300 Owners Manual_USA_OM78211U
■ People suffering illness
Obtain medical advice and wear the seat
belt in the proper way. (→P.25)
■ When children are in the vehicle
Do not allow children to play with the
seat belt. If the seat belt becomes twisted
around a child’s neck, it may lead to
choking or other serious injuries that
could result in death. If this occurs and
the buckle cannot be unfastened, scissors should be used to cut the belt.
■ Seat belt damage and wear
● Do not damage the seat belts by allow-
ing the belt, plate, or buckle to be
jammed in the door.

WARNING
WARNING
Do not twist the seat belt.

● Inspect the seat belt system periodi-
cally. 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 Lexus
dealer.
● Replace the seat assembly, including
the belts, if your vehicle has been
involved in a serious accident, even if
there’s 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 Lexus dealer. Inappropriate handling may lead to incorrect operation.
Correct use of the seat belts
■ 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.46)
● When the child becomes large enough to
properly wear the vehicle’s seat belt, follow the instructions regarding seat belt
usage. (→P.26)
■ 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 Lexus dealer free of charge.

For safety and security
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 possi-
ble over the hips.
Adjust the position of the seatback.
Sit up straight and well back in the
seat.

■ 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.
● Do not wear the seat belt extender if
you can fasten the seat belt without the
extender.
● Do not use the seat belt extender
when installing a child restraint system
because the belt will not securely hold
the child restraint system, increasing
the risk of death or serious injury in the
event of an accident.

■ Seat belt pretensioners
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.
● Do not place anything, such as a cush-
ion, on the front passenger’s seat.
Doing so will disperse the passenger’s
weight, which prevents the sensor
from detecting the passenger’s weight
properly. As a result, the seat belt pretensioner for the front passenger’s seat
may not activate in the event of a collision.
● If the pretensioner has activated, the
SRS warning light will come on. In that
case, the seat belt cannot be used
again and must be replaced at your
Lexus dealer.
