amount of electromagnetic waves as the co nventional gasoline powered vehicles or
home electronic appliances despite of their electromagnetic shielding.
Unwanted noise may occur in the rece ption of the mobile two-way radio.
Installation of a mobile two-way radio system

10
RX450h_U_OM0E013UYour 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 (tract ion battery) status
The recorded data varies accord ing to the vehicle grade level and options with which it is
equipped. Furthermore, these computers do no t record conversations, sounds or pic-
tures.
●Data usage
Lexus may use the data recorded in these computers 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 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 law suit
• For research purposes where the data is not tied to a specific vehicle or vehicle
owner
●Usage of data collected thro ugh Safety Connect / Lexus Enform (U.S. mainland only)
If your Lexus has Safety Connect or Lexus En form and if you have subscribed to those
services, please refer to the Safety Connect / Lexus Enform Telematics Subscription
Service Agreement for information on data collected and its usage.
Vehicle data recordings

11
RX450h_U_OM0E013UThis 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 a ssist 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 ti me, typically 30 seconds or less.
The EDR in this vehicle is desi gned to record such data as:
• How various systems in your vehicle were operating;
• Whether or not the driver and passenge r safety belts were buckled/fastened;
• How far (if at all) the driver was depressi ng 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 norm al 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 vehi-
cle or the EDR is needed. In addition to the vehicle manufacturer, other parties, such as
law enforcement, that have the special equipm ent, 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 law suit
However, if necessary, Lexus may:
• Use the data for research on vehicle safety performance
• Disclose the data to a third party for rese arch purposes without disclosing informa-
tion about the specific vehicle or vehicle owner

■Regenerative braking
In the following situations, kinetic energy is converted to electric energy and decelera-
tion force can be obtained in conjunction with the recharging of the hybrid battery (trac-
tion battery).
●The accelerator pedal is released while driving with the shift lever in D or S.
●The brake pedal is depressed while driving with the shift lever in D or S.
■EV indicator
■Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops automati cally. However, it may not stop automati-
cally in the following conditions:
●During gasoline engine warm-up
●During hybrid battery (traction battery) charging
●When the temperature of the hybrid battery (traction battery) is high or low
●When the heater is switched on
■Charging the hybrid battery (traction battery)
As the gasoline engine charges the hybrid battery (traction battery), the battery does not
need to be charged from an ou tside source. However, if the vehicle is left parked for a
long time the hybrid battery (traction batter y) will slowly discharge. For this reason, be
sure to drive the vehicle at least once every few months for at least 30 minutes or 10
miles (16 km). If the hybrid battery (traction battery) beco mes fully discharged and you
are unable to start the hybrid system, contact your Lexus dealer.
■Charging the 12-volt battery
 P. 570
■After the 12-volt battery has discharged or when the terminal has been removed and
installed during exchange, etc.
The gasoline engine may not stop even if the vehicle is being driven by the hybrid battery
(traction battery). If this continues fo r a few days, contact your Lexus dealer.
The EV indicator comes on when the vehicle is
driven using only the el
ectric motor (traction
motor) or the gasoline engine is stopped.

■Sounds and vibrations specific to a hybrid vehicle
There may be no engine sound or vibration even though the vehicle is able to move with
the “READY” indicator is illuminated. For safety, make sure to shift the shift lever to P and
apply the parking brake when parked.
The following sounds or vibrations may occu r when the hybrid system is operating and
are not a malfunction:
●Motor sounds may be heard from the engine compartment.
●Sounds may be heard from the hybrid battery (traction battery) behind the rear seats
when the hybrid system starts or stops.
●Relay operating sounds such as a snap or so ft clank will be emitted from the hybrid bat-
tery (traction battery), behind the rear se ats, when the hybrid system is started or
stopped.
●Sounds from the hybrid system may be heard when the back door is open.
●Sounds may be heard from the transmission wh en the gasoline engine starts or stops,
when driving at low spee ds, or during idling.
●Engine sounds may be heard when accelerating sharply.
●Sounds may be heard due to regenerative braking when the brake pedal is depressed
or as the accelerator pedal is released.
●Vibration may be felt when the ga soline engine starts or stops.
●Cooling fan sounds may be heard from th e air intake vents under the rear seats.
■Vehicle proximity notification system
In the following cases, the vehicle proximity notification system may be difficult for sur-
rounding people to hear.
●In very noisy areas
●In the wind or the rain
Also, as the vehicle proximity notification system is installed on the front of the vehicle, it
may be more difficult to hear from the re ar of the vehicle compared to the front.
■Maintenance, repair, recycling, and disposal
Contact your Lexus dealer regarding mainte nance, repair, recycling and disposal. Do
not dispose of the vehicle yourself.
■Customization
Some functions can be customized. ( P. 607)

WARNING
■Road accident cautions
Observe the following precautions to reduce the risk of death or serious injury:
●Pull your vehicle off the road, shift the shift lever to P, apply the parking brake, and
turn the hybrid system off.
●Do not touch the high voltage parts, cables and connectors.
●If electric wires are exposed inside or outside your vehicle, an electric shock may
occur. Never touch exposed electric wires.
●If a fluid leak occurs, do not touch the flui d as it may be strong alkaline electrolyte
from the hybrid battery (traction battery). If it comes into contact with your skin or
eyes, wash it off immediately with a large amount of water or, if possible, boric acid
solution. Seek immedi ate medical attention.
●If a fire occurs in the hybrid vehicle, leave the vehicle as soon as possible. Never use a
fire extinguisher that is not meant for el ectric fires. Using even a small amount of
water may be dangerous.
●If your vehicle needs to be towed, do so with front wheels (2WD models) or four
wheels (AWD models) raised. If the wheels connected to the electric motor (traction
motor) are on the ground when towing, the motor may continue to generate electric-
ity. This may cause a fire. ( P. 530)
●Carefully inspect the ground under the vehicle. If you find that liquid has leaked onto
the ground, the fuel system may have been damaged. Leave the vehicle as soon as
possible.
