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 hybr id 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.
Installation of a mobile two-way radio system

10
LS600hL_U(OM50E41U)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. Furthermore, these computers do not record conversations,
sounds or pictures.
● 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 law suit
• For research purposes where the data is not tied to a specific vehicle or vehicle owner
● Usage of data collected through Safety Connect / Lexus Enform (U.S. mainland
only)
If your Lexus has Safety Connect or Lexus Enform and if you have subscribed to
those services, please refer to the Safety Connect / Lexus Enform Telematics Sub-
scription Service Agreement for informat ion on data collected and its usage.
Vehicle data recordings

11
LS600hL_U(OM50E41U)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 desi gned to record data related to vehicle
dynamics and safety systems for a short peri od 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 passenge r 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 unde rstanding 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 ac quired 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 law suit
However, if necessary, Lexus may:
• Use the data for research on vehicle safety performance
• Disclose the data to a third party for re search purposes without disclosing infor-
mation about the specific vehicle or vehicle owner

LS600hL_U(OM50E41U)
■Regenerative braking
In the following situations, kinetic energy is converted to electric energy and decel-
eration force can be obtained in conjunction with the recharging of the hybrid bat-
tery (traction battery).
●The accelerator pedal is released while driving with the shift position in D or S.
●The brake pedal is depressed while driving with the shift position in D or S.
■EV indicator
■Conditions in which the gasoline engine may not stop
The gasoline engine starts and stops auto matically. However, it may not stop auto-
matically in the following conditions:
●During gasoline engine warm-up
●During hybrid battery (t raction 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 outside source. However, if the vehicle is left
parked for a long time the hybrid battery 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 becomes fully discharged and you are unable
to jump-start the vehicle with the 12-v olt battery, contact your Lexus dealer.
●If the shift lever is in N, the hybrid ba ttery (traction battery) will not be charged.
Always put the shift lever in P when the vehicle is stopped. When driving in heavy
traffic, operate the vehicle with the shift le ver in D or S to avoid discharging the bat-
tery.
●To help prevent the 12-volt battery from becoming discharged, drive the vehicle at
least once a month, and operate the acces sories only when the “READY” indicator
is on. When parking the vehicle, make sure the doors and trunk are closed and all
lights are turned off.
■Charging the 12-volt battery
 P. 5 2 8
The EV indicator comes on when the vehicle
is driven using only the electric motor (trac-
tion motor) or the gasoline engine is stopped.

■After the 12-volt battery has discharged or has been changed or removed
The gasoline engine may not stop even if the vehicle is running on the hybrid battery
(traction battery). If this continues for a few days, contact your Lexus dealer.
■Sounds and vibrations specific to a hybrid vehicle
There may be no engine sounds or vibration even though the vehicle is able to move.
For safety, apply the parking brake and make sure to shift the shift lever to P when
parked.
The following sounds or vibrations may occur 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.
●Sounds from the hybrid system may be heard when the trunk lid is open.
●Sounds may be heard from the hybrid tran smission when the hybrid system starts
or stops.
●Engine sounds may be heard when accelerating sharply.
●Sounds may be heard due to regenerative braking when the accelerator pedal is
released or the brake pedal is depressed.
●Vibration may be felt or sounds may be heard when the gasoline engine starts or
stops.
●Cooling fan sounds may be heard from the air intake vents on the package tray.

CAUTION
■Road accident cautions
Observe the following precautions to reduce the risk of death or serious injury:
●Pull your vehicle off the road, apply the parking brake, shift the shift lever to P, 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 imme diate 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 electric fires. Using even a small
amount of water may be dangerous.
●If your vehicle needs to be towed, do so with four wheels raised. If the wheels con-
nected to the electric motor (traction mo tor) are on the ground when towing, the
motor may continue to generate electricity. This may cause an electricity leakage
leading to a fire. ( P. 4 8 6 )
●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.
