LS500h_OM_OM50F42U_(U) hybrid vehicles emit approximately the
same amount of electromagnetic
waves as the conventional gasoline
powered vehicles or home electronic
appliances despite of their electro-
magnetic shielding.
Unwanted noise may occur in the
reception of the mobile two-way radio.
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
 Images from the camera sensor
(available only in situations when
sudden inputs o ccur while driving
[sudden acceleration, etc.], the
pre-collision braking function or the
pre-collision brake assist function
was operating, the Parking Support
Brake function [static objects] was
operating, or your vehicle was
involved in a collision)
The recorded data varies according to
the vehicle grade level and options
with which it is equipped. These com-
puters do not record conversations or sounds, and only record images out-
side of the vehicle in certain situations.
 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 vehi-
cle 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
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 refe r to the Safety Con-
nect / Lexus Enform Telematics Subscrip-
tion Service Agreement for information on
data collected and its usage.
This vehicle is equipped with an event
data recorder (EDR). The main pur-
pose 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 dynam-Vehicle data recordings

Before driving airport or other faci lity that generates
strong radio waves or electrical noise●
When carrying a portable radio, cellular
phone, cordless phone or other wireless
communication device●
When the electronic key is in contact
with, or is covered by the following metal-
lic objects
• Cards to which aluminum foil is attached
• Cigarette boxes that have aluminum foil
inside
• Metallic wallets or bags
•Coins
• Hand warmers made of metal
• Media such as CDs and DVDs ●
When other wireless ke ys (that emit radio
waves) are being used nearby●
When carrying the electronic key
together with the following devices that
emit radio waves
• Another vehicle’s electronic key or a
wireless key that emits radio waves
• Personal computers or personal digital
assistants (PDAs)
• Digital audio players
• Portable game systems ●
If window tint with a metallic content or
metallic objects are attached to the rear
window●
When the electronic key is placed near a
battery charger or electronic devices●
When the vehicle is parked in a pay park-
ing spot where radio waves are emitted.■
Note for the entry function●
Even when the electronic key is within the
effective range (detection areas), the sys-
tem may not operate properly in the fol-
lowing cases:
• The electronic key is too close to the win-
dow or outside door handle, near the
ground, or in a high place when the doors
are locked or unlocked.
• The electronic key is near the ground or
in a high place, or too close to the center
of the rear bumper when the trunk is
opened.
• The electronic key is on the instrument
panel, rear package tray or floor, or in the
door pockets or glove box when the
hybrid system is star ted or power switch modes are changed. ●
Do not leave the electronic key on top of
the instrument panel or near the door
pockets when exiting the vehicle.
Depending on the radio wave reception
conditions, it may be detected by the
antenna outside the cabin and the doors
will become lockable from the outside,
possibly trapping the electronic key
inside the vehicle. ●
As long as the electronic key is within the
effective range, the doors may be locked
or unlocked by anyone. However, only
the doors detecting the electronic key
can be used to unlock the vehicle. ●
Even if the electronic key is not inside the
vehicle, it may be po ssible to start the
hybrid system if the el ectronic key is near
the window. ●
The doors may unlock or lock if a large
amount of water splashes on the door
handle, such as in the rain or in a car
wash, when the electronic key is within
the effective range. (The doors will auto-
matically be locked after approximately
60 seconds if the doors are not opened
and closed.) ●
If the wireless remote control is used to
lock the doors when the electronic key is
near the vehicle, there is a possibility that
the door may not be unlocked by the
entry function. (Use the wireless remote
control to unlock the doors.) ●
Touching the door lock sensor while
wearing gloves may delay or prevent lock
operation. ●
When the lock operation is performed
using the lock sensor, recognition signals
will be shown up to two consecutive
times. After this, no recognition signals
will be given.
●
If the door handle becomes wet while the
electronic key is within the effective
range, the door may lock and unlock
repeatedly. In this case, follow the follow-
ing correction procedures to wash the
vehicle:
• Place the electronic key in a location 6 ft.
(2 m) or more away from the vehicle.
(Take care to ensure that the key is not
stolen.)

Stopping the hybrid system WARNING■
Stopping the hybrid system in an
emergency ●
If you want to stop the hybrid system in
an emergency while driving the vehi-
cle, press and hold the power switch
for more than 2 seconds, or press it
briefly 3 times or more in succession.
( → P.420)
However, do not touch the power
switch while driving except in an emer-
gency. Turning the hybrid system off
while driving will not cause loss of
steering or braking control, however,
power assist to the st eering will be lost.
This will make it more difficult to steer
smoothly, so you should pull over and
stop the vehicle as soon as it is safe to
do so. ●
If the power switch is operated while
the vehicle is running, a warning mes-
sage will be shown on the multi-infor-
mation display and a buzzer sounds. ●
