LS500h_OM_OM50F42U_(U) Please note that this manual applies to
all models and explains all equipment,
including options. Therefore, you may
find some explanat ions for equipment
not installed on your vehicle.
All specifications provided in this man-
ual 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 vehi-
cle shown in the illustrations may differ
from your vehicle in terms of color and
equipment.
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 mal-
function.
A wide variety of non-genuine spare
parts and accessories for Lexus vehi-
cles are currently available in the mar-
ket. 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 vio-
late governmental regulations. In addi-
tion, damage or performance
problems resulting from the modifica-
tion may not be covered under war-
ranty.
The installation of a mobile two-way
radio system in your vehicle could
affect electronic systems such as:
 Hybrid system
 Multiport fuel injection sys-
tem/sequential multiport fuel injec-
tion system
 Lexus Safety System+A
 Lexus Safety System+
 Anti-lock brake system
 Vehicle dynamics integrated man-

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 pas-
senger safety belts were buck-
led/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 nontrivial crash situa-
tion occurs; no data are recorded by
the EDR under normal driving condi-
tions 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, spe-
cial 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
The SRS airbag, seat belt pretensioner
devices and Pop Up Hood system in
your Lexus contain explosive chemi-
cals. If the vehicle is scrapped with the
airbags, seat belt pretensioners and
Pop Up Hood micro gas generators
left as they are, this may cause an acci-
dent such as fire. Be sure to have the
systems of the SRS airbag, seat belt
pretensioner and Pop Up Hood micro
gas generators removed and disposed
of by a qualified service shop or by
your Lexus dealer before you scrap
your vehicle.

LS500h_OM_OM50F42U_(U) WARNING●
Do not lean against the door, the roof
side rail or the front, side and rear pil-
lars.
●
Do not allow anyone to kneel on the
passenger seats towa rd the door or
put their head or hands outside the
vehicle.
●
Do not attach anything to or lean any-
thing against areas such as the dash-
board, steering wheel pad and lower
portion of the in strument panel.
These items can become projectiles
when the SRS driver, front passenger
and knee airbags deploy. ●
Do not attach anything to areas such
as a door, windshie ld, side windows,
front or rear pillar, roof side rail and
assist grip.
●
Do not hang coat hangers or hard
objects on the coat hooks. All of these
items could become projectiles and
may cause death or serious injury,
should the SRS curtain shield airbags
deploy. ●
If a vinyl cover is put on the area where
the SRS knee airbag will deploy, be
sure to remove it. ●
Do not use seat accessories which
cover the parts where the SRS side air-
bags inflate as they may interfere with
inflation of the SRS airbags. Such
accessories may prevent the side air-
bags from activating correctly, disable
the system or cause the side airbags to
inflate accidentally, resulting in death
or serious injury.
●
Do not strike or apply significant levels
of force to the area of the SRS airbag
components or the front doors. Doing
so can cause the SRS airbags to mal-
function.
●
Do not touch any of the component
parts immediately after the SRS air-
bags have deployed (inflated) as they
may be hot.
●
If breathing becomes difficult after the
SRS airbags have deployed, open a
door or window to allow fresh air in, or
leave the vehicle if it is safe to do so.
Wash off any residue as soon as possi-
ble to prevent skin irritation.

■
Front passenger occupant classifica-
tion system precautions
Observe the following precautions
regarding the front passenger occupant
classification system.
Failure to do so may cause death or seri-
ous injury. ●
Wear the seat belt properly.
●
Make sure the front passenger’s seat
belt plate has not been left inserted
into the buckle before someone sits in
the front passenger seat.

411-1. For safe use
LS500h_OM_OM50F42U_(U) 1
For safety and security WARNING●
Make sure the “AIR BAG OFF” indica-
tor light is not illuminated when using
the seat belt extender for the front pas-
senger seat. If the “AIR BAG OFF”
indicator light is illuminated, discon-
nect the extender tongue from the seat
belt buckle, and reconnect the seat
belt. Reconnect the se at belt extender
after making sure the “AIR BAG ON”
indicator light is illu minated. If you use
the seat belt extender while the “AIR
BAG OFF” indicator light is illumi-
nated, the SRS airbags for the front
passenger will not activate, which
could cause death or serious injury in
the event of a collision.●
Do not apply a heavy load to the front
passenger seat or equipment (e.g.
seatback pocket).●
Do not put weight on the front passen-
ger seat by putting your hands or feet
on the front passenger seat seatback
from the rear passenger seat.●
Do not let a rear passenger lift the
front passenger seat with their feet or
press on the seatback with their legs.●
Do not put objects under the front pas-
senger seat.
●
Do not recline the front passenger
seatback so far that it touches a rear
seat. This may cause the “AIR BAG
OFF” indicator light to be illuminated,
which indicates that the SRS airbags
for the front passenger will not activate
in the event of a severe accident. If the
seatback touches the rear seat, return
the seatback to a position where it
does not touch the rear seat. Keep the
front passenger seatback as upright as
possible when the vehicle is moving.
Reclining the seatback excessively
may lessen the effectiveness of the
seat belt system. ●
If an adult sits in the front passenger
seat, the “AIR BAG ON” indicator light
is illuminated. If the “AIR BAG OFF”
indicator is illuminated, ask the passen-
ger to sit up straight, well back in the
seat, feet on the floor, and with the seat
belt worn correctly. If the “AIR BAG
OFF” indicator still remains illumi-
nated, either ask the passenger to
move to the rear seat, or if that is not
possible, move the front passenger
seat fully rearward. ●
When it is unavoidable to install a for-
ward-facing child re straint system on
the front passenger seat, install the
child restraint system on the front pas-
senger seat in the proper order.
( → P.46)●
Do not modify or remove the front
seats. ●
Do not kick the front passenger seat or
subject it to severe impact. Otherwise,
the SRS warning light may come on to
indicate a malfunction of the front pas-
senger occupant clas sification system.
In this case, contact your Lexus dealer
immediately. ●
Child restraint systems installed on the
rear seat should not contact the front
seatbacks.
●
Do not use a seat accessory, such as a
cushion and seat cover, that covers the
seat cushion surface.
●
Do not modify or replace the uphol-
stery of the front seat.

WARNING
■
When using a child restraint system
Observe the following precautions.
Failure to do so may result in death or
serious injury.
●
Never install a rear-facing child
restraint system on the front passenger
seat even if the “AIR BAG OFF” indi-
cator light is illuminated. In the event of
an accident, the force of the rapid infla-
tion of the front passenger airbag can
cause death or serious injury to the
child if the rear-fac ing child restraint
system is installed on the front passen-
ger seat.

491-2. Child safety
LS500h_OM_OM50F42U_(U) 1
For safety and security
A child restraint system for a small
child or baby must itself be properly
restrained on the seat with the lap por-
tion of the lap/shoulder belt. ■
Installing child restraint system
using a seat belt (child restraint
lock function belt)
Install the child restraint system in
accordance to the operation manual
enclosed with the child restraint sys-
tem.WARNING●
A forward-facing child restraint system
may be installed on the front passen-
ger seat only when it is unavoidable. A
child restraint system that requires a
top tether strap should not be used in
the front passenger seat since there is
no top tether strap anchor for the front
passenger seat.●
A forward-facing child restraint system
may be installed on the front passen-
ger seat only when it is unavoidable.
When installing a forward-facing child
restraint system on the front passenger
seat, adjust the seatback angle to the
most upright position, move the seat to
the rearmost position, and raise the
seat to the upper most position, even if
the “AIR BAG OFF” indicator light is
illuminated.
●
Do not allow the child to lean his/her
head or any part of his/her body
against the door or the area of the seat,
front or rear pillars, or roof side rails
from which the SRS side airbags or
SRS curtain shield ai rbags deploy even
if the child is seated in the child
restraint system. It is dangerous if the
SRS side and curtain shield airbags
inflate, and the impact could cause
death or serious injury to the child. ●
When a booster seat is installed,
always ensure that th e shoulder belt is
positioned across the center of the
child’s shoulder. The belt should be
kept away from the child’s neck, but
not so that it could fall off the child’s
shoulder. ●
Use child restraint system suitable to
the age and size of the child and install
it to the rear seat. ●
If the driver’s seat interferes with the
child restraint system and prevents it
from being attached correctly, attach
the child restraint system to the
right-hand rear seat.
●
Adjust the front passe nger seat so that
it does not interfere with the child
restraint system.
