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 hybrid system
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 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
damage 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.
RX450h_RX450hL_U_OM48F85U
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:
● Hybrid system
● Multiport fuel injection system/sequential multiport fuel injection system
● Lexus Safety System+
● Anti-lock brake system
● Vehicle dynamics integrated management
● 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.
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 electromagnetic shielding.
Unwanted noise may occur in the reception of the mobile two-way radio.

Vehicle data recordings
Your Lexus is equipped with several sophisticated computers that will record certain
data, such as:
• Engine speed
• Electric motor speed (traction motor speed)
• Accelerator status
•Brake status
• Vehicle speed
•Shift position
• Hybrid battery (traction battery) status
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/
.
RX450h_RX450hL_U_OM48F85U
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 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 informa-
tion about the specific vehicle or vehicle owner

WARNING
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.
■ General precaution regarding children’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 addition, heat build-up or
extremely cold temperatures inside the vehicle can be fatal to children.

Floor mat
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.
Insert the retaining hooks (clips) into

1-1. For safe use
WARNING
● Check that the floor mat is securely fixed in
the correct place with all the provided retaining hooks (clips). Be especially careful to perform this check after cleaning the floor.
● With the hybrid system stopped and the shift
lever in P, fully depress each pedal to the floor
to make sure it does not interfere with the
floor mat.
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.
● Do not use two or more floor mats on top of each other.
● Do not place the floor mat bottom-side up or upside-down.
