LS500_OM_(U)_1810 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
engine 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.
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:
 Multiport fuel injection sys-
tem/sequential multiport fuel injec-
tion system
 Lexus Safety System + A
 Lexus Safety System + 2.0
 Anti-lock brake system
 Vehicle dynamics integrated man-
agement
 SRS airbag system
 Seat belt pretensioner system
Be sure to check with your Lexus
dealer for precautionary measures or
special instructions regarding installa-
tion of a mobile two-way radio system.
The vehicle is equipped with sophisti-For your information Main Owner’s Manual

Vehicle data recordings

LS500_OM_(U)_1810 ics 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 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 non-trivial 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.
Special handling may apply, See
www.dtsc.ca.gov/hazard-
ouswaste/perchlorate.
Your vehicle has components that may
contain perchlorate. These compo-
nents may include airbag, seat belt pre- Scrapping of your Lexus

Your vehicle is equipped with ADVANCED AIRBAGS designed based on the US
motor vehicle safety standards (FMVSS208). The airbag sensor assembly (ECU)
controls airbag deployment based on information obtained from the sensors etc.
shown in the system components diagram above. This information includes crash
severity and occupant information. As the airbags deploy, a chemical reaction in
the inflators quickly fills the airbags with no n-toxic gas to help restrain the motion of
the occupants. ■
If the SRS airbags deploy (inflate)●
Slight abrasions, burns, bruising etc., may
be sustained from SRS airbags, due to the
extremely high speed deployment (infla-
tion) by hot gases.●
A loud noise and white powder will be
emitted.●
Parts of the airbag module (steering
wheel hub, airbag cover and inflator) as
well as the seats, parts of the front and
rear pillars, and roof side rails, may be hot
for several minutes. The airbag itself may
also be hot.●
The windshield may crack.●
All of the doors will be unlocked.

The brakes and stop lights will be con-
trolled automatically. (  P.294)
●
The interior lights will turn on automati-
cally. (  P.334)
●
The emergency flashers will be turned on
automatically. (  P.406)

For Lexus Enform Safety Connect sub-
scribers, if any of the following situations
occur, the system is designed to send an
emergency call to the response center,
notifying them of the vehicle’s location
(without needing to push the “SOS” but- ton) and an agent will attempt to speak
with the occupants to ascertain the level
of emergency and assistance required. If
the occupants are unable to communi-
cate, the agent automatically treats the
call as an emergency and helps to dis-
patch the necessary emergency services.
(  P.58)
• An SRS airbag is deployed.
• A seat belt pretensioner is activated.
• The vehicle is involved in a severe
rear-end collision. ■
PCS-linked SRS airbag deployment
control (vehicles with Lexus Safety Sys-
tem + A)
If the PCS (Pre-Collision System) deter-
mines that the possibility of a side collision is
high, the SRS side and curtain shield air-
bags will be prepared to operate.
■
SRS airbag deployment conditions (SRS
front airbags/SRS seat cushion airbags)
●
The SRS front airbags and SRS seat cush-
ion airbags will deploy in the event of an
impact that exceed s the set threshold
level (the level of fo rce corresponding to
an approximately 12 - 18 mph [20 - 30
km/h] frontal collision with a fixed wall
that does not move or deform).
However, this threshol d velocity will be
considerably higher in the following situa-
tions:
