Your Lexus is equipped with several sophisticated computers that will record certain
data, such as:• Engine speed
• Accelerator status
•Brake status
• Vehicle speed
•Shift position
The recorded data varies accord ing to the vehicle grade level and options with which it is
equipped. These computers do not record conversations or sounds, and only record
images outside of the vehicle in certain situations.
●Data Transmission
Your vehicle may transmit the data recorded in these computers to Lexus without noti-
fication to you.
●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 lawsuit
• For research purposes where the data is not tied to a specific vehicle or vehicle
owner
●Usage of data collected through Le xus Enform (U.S. mainland only)
If your Lexus has Lexus Enform and if you have subscribed to those services, please
refer to the Lexus Enform Telematics Subs cription Service Agreement for information
on data collected and its usage.

Vehicle data recordings

10
GX460_OM_OM60Q09U_(U)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 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 lawsuit
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

For safety and security
CAUTION
Observe the following precautions.
Failure to do so may cause the driver’s floor mat to slip, possibly interfering with the ped-
als while driving. An unexpectedly high spee d may result or it may become difficult to
stop the vehicle. This could lead to an ac cident, resulting in death or serious injury.
■When installing the driver’s floor mat
●Do not use floor mats designed for other models or different model year vehicles,
even if they are Lexus Genuine floor mats.
●Only use floor mats designed for the driver’s seat.
●Always install the floor mat securely using the retain ing hooks (clips) provided.
●Do not use two or more floor mats on top of each other.
●Do not place the floor mat bottom-side up or upside-down.
■Before driving
●Check that the floor mat is securely fixed in
the correct place with all the provided retain-
ing hooks (clips). Be especially careful to per-
form this check after cleaning the floor.
●With the engine stopped and the shift lever in
P, fully depress each pedal to the floor to
make sure it does not interfere with the floor
mat.

For safe driving
Adjust the angle of the seatback so
that you are sitting straight up and so
that you do not have to lean forward
to steer. (→P. 122)
Adjust the seat so that you can
depress the pedals fully and so that
your arms bend slightly at the elbow
when gripping the steering wheel.
(→ P. 122)
Lock the head restraint in place with th e center of the head restraint closest to
the top of your ears. ( →P. 140)
Wear the seat belt correctly. ( →P. 30)
Make sure that all occupants are wearing their seat belts before driving the vehi-
cle. ( →P. 30)
Use a child restraint system appropriate for the child until the child becomes
large enough to properly wear the vehicle’s seat belt. ( →P. 55)

For safety and security
Make sure that you can see backward clearly by adjusting the inside and outside
rear view mirrors properly. ( →P. 145, 147)
Adjusting the mirrors
CAUTION
Observe the following precautions.
Failure to do so may result in death or serious injury.
●Do not adjust the position of the driver’s seat while driving.
Doing so could cause the driver to lose control of the vehicle.
●Do not place a cushion between the dr iver or passenger and the seatback.
A cushion may prevent correct posture from being achieved, and reduce the effec-
tiveness of the seat be lt and head restraint.
●Do not place anything under the front seats.
Objects placed under the fr ont seats may become jammed in the seat tracks and stop
the seat from locking in plac e. This may lead to an accident and the adjustment mech-
anism may also be damaged.
●Always observe the legal speed limi t when driving on public roads.
●When driving over long distances, take regular breaks before you start to feel tired.
Also, if you feel tired or sleepy while drivin g, do not force yourself to continue driving
and take a break immediately.

For safety and security
Push the seat belt shoulder anchor
down while pressing the release but-
ton.
Push the seat belt shoulder anchor
up.
Move the height adjuster up and down
as needed until you hear a click.
The pretensioners help the seat belts to
quickly restrain the occupants by
retracting the seat belts when the vehi-
cle is subjected to certain types of
severe frontal or side collision or a vehi-
cle rollover.
The pretensioners do not activate in the
event of a minor frontal or side impact,
or a rear impact.
If the system determines that a collision is unavoidable, the front seat belts will
retract before the collision. ( →P. 368)

■Emergency locking retractor (ELR)
The retractor will lock the belt during a sudden stop or on impact. It may also lock if you
lean forward too quickly. A slow, easy motion w ill allow the belt to extend so that you can
move around fully.
■Automatic locking retractor (ALR)
When a passenger’s shoulder belt is completely extended and then retracted even
slightly, the belt is locked in that position and cannot be extended. This feature is used to
hold the child restraint system (CRS) firmly. To free the belt again, fully retract the belt
and then pull the belt out once more. ( →P. 59)
■Child seat belt usage
The seat belts of your vehicle were principally designed for persons of adult size.
●Use a child restraint system appropriate fo r the child, until the child becomes large
enough to properly wear the vehicle’s seat belt. ( →P. 55)
●When the child becomes large enough to properly wear the vehicle’s seat belt, follow
the instructions on P. 30 regarding seat belt usage.
■Replacing the belt after the pr etensioner has been activated
If the vehicle is involved in multiple collisions, the pretensioner will activate for the first
collision, but will not activate for th e second or subsequent collisions.
■Seat belt extender
If your seat belts cannot be fastened securely
because they are not long enough, a personal-
ized seat belt extender is available from your
Lexus dealer free of charge.
