Vehicle data recordings

10
RX350/RX350L_UThis 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

WARNING
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.

WARNING
■SRS airbag precautions
Observe the following precautions regarding the SRS airbags.
Failure to do so may cause death or serious injury.
●The driver and all passengers in the vehicle must wear their seat belts properly.
The SRS airbags are supplemental devices to be us ed with the seat belts.
●The SRS driver airbag deploys with considerable force, and can cause death or seri-
ous injury especially if the driver is very close to the airbag. The National Highway
Traffic Safety Administration (NHTSA) advises:
Since the risk zone for the driver’s airbag is the first 2 - 3 in. (50 - 75 mm) of inflation,
placing yourself 10 in. (250 mm) from your driver airbag provides you with a clear
margin of safety. This distance is measured from the center of the steering wheel to
your breastbone. If you sit less than 10 in . (250 mm) away now, you can change your
driving position in several ways:
• Move your seat to the rear as far as you can while still reaching the pedals com-
fortably.
• Slightly recline the back of the seat. Although vehicle designs vary, many drivers can achieve the 10 in. (250 mm) dis-
tance, even with the driver seat all the wa y forward, simply by reclining the back of
the seat somewhat. If reclining the back of your seat makes it hard to see the road,
raise yourself by using a firm , non-slippery cushion, or raise the seat if your vehicle
has that feature.
• If your steering wheel is ad justable, tilt it downward. This points the airbag toward
your chest instead of your head and neck.
The seat should be adjusted as recommended by NHTSA ab ove, while still maintain-
ing control of the foot pedals, steering whee l, and your view of the instrument panel
controls.
●The SRS front passenger airbag also deploy s with considerable force, and can cause
death or serious injury especially if the front passenger is very close to the airbag. The
front passenger seat should be as far from the airbag as possible with the seatback
adjusted, so the front passenger sits upright.
●If the seat belt extender has been connected
to the front seat belt buckles but the seat belt
extender has not also been fastened to the
latch plate of the seat belt, the SRS front air-
bags will judge that the driver and front pas-
senger are wearing the seat belt even though
the seat belt has not been connected. In this
case, the SRS front airbags may not activate
correctly in a collision, resulting in death or
serious injury in the event of a collision. Be
sure to wear the seat belt with the seat belt
extender.

■If the SRS airbags deploy (inflate)
●Slight abrasions, burns, bruising etc., may be sustained from SRS airbags, due to the
extremely high speed deployment (inflation) 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
front 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.
●For Lexus Enform Safety Connect subscribers, if any of the following situations occur,
the system is designed to send an emerge ncy call to the response center, notifying
them of the vehicle’s location (without needing to push the “SOS” button) and an agent
will attempt to speak with the occupants to ascertain the level of emergency and assis-
tance required. If the occupants are unable to communicate, the agent automatically
treats the call as an emergency and helps to dispatch the necessary emergency ser-
vices. ( P. 568)
• An SRS airbag is deployed.
• A seat belt pretensioner is activated.
• The vehicle is involved in a severe rear-end collision.
WARNING
■Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications without
consulting your Lexus dealer. The SRS airb ags may malfunction or deploy (inflate)
accidentally, causing death or serious injury.
●Installation, removal, disassembly and repair of the SRS airbags
●Repairs, modifications, removal or replacement of the steering wheel, instrument
panel, dashboard, seats or seat upholstery, front, side and rear pillars, roof side rails,
front door panels, front door trims, or front door speakers
●Modifications to the front door panel (such as making a hole in it)
●Repairs or modifications of the front fend er, front bumper, or side of the occupant
compartment
●Installation of a grille guard (bull bars, ka ngaroo bar, etc.), snow plows, winches or
roof luggage carrier
●Modifications to the vehicle’s suspension system
●Installation of electronic devices such as mobile two-way radios and CD players
●Modifications to your vehicle for a person with a physical disability

■SRS airbag deployment conditions (SRS front airbags)
●The SRS front airbags will deploy in the event of an impact that exceeds the set threshold
level (the level of force corresponding to an approximat ely 12-18 mph [20-30 km/h]
frontal collision with a fixed wall that does not move or deform).
However, this threshold velocity will be cons iderably higher in the following situations:
• If the vehicle strikes an object, such as a parked vehicle or sign pole, which can move
or deform on impact
• If the vehicle is involved in an underride collision, such as a collision in which the
front of the vehicle “underrides”, or goes under, the bed of a truck
●Depending on the type of collision, it is possi ble that only the seat belt pretensioners will
activate.
●The SRS front airbags for the fr ont passenger will not activate if there is no passenger
sitting in the front passenger seat. However, the SRS front airbags for the front passen-
ger may deploy if luggage is put in the seat, even if the seat is unoccupied. ( P. 47)
●The SRS seat cushion airbag on the front pa ssenger seat will not operate if the occu-
pant is not wear ing a seat belt.
■SRS airbag deployment conditions (S RS side and curtain shield airbags)
●The SRS side and curtain shield airbags w ill deploy in the event of an impact that
exceeds the set threshold level (the level of force corresponding to the impact force
produced by an approximately 3300 lb. [15 00 kg] vehicle colliding with the vehicle
cabin from a direction perpendicular to the vehicle orientation at an approximate
speed of 12 -18 mph [20 -30 km/h]).
●Both SRS curtain shield airbags will de ploy in the event of vehicle rollover.
●All SRS side and curtain shield airbags will de ploy in the event of a severe frontal colli-
sion.
■Conditions under which the SRS airbags may deploy (inflate), other than a collision
The SRS front airbags and SRS si de and curtain shield airbags may also deploy if a seri-
ous impact occurs to the underside of your vehicle. Some examples are shown in the
illustration.
●Hitting a curb, edge of pavement or hard sur-
face
●Falling into or jumping over a deep hole
●Landing hard or falling
