If the SRS airbags deploy (inflate) ●
Slight abrasions, burns, brui sing 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, side and rear pillars and roof side rails, may be hot for sev-
eral minutes. The airbag itself may also be hot.●
The windshield may crack. ●
For Lexus Enform Safety Connect subscribers, if the SRS airbags deploy or in the event
of a severe rear-end collision, 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” button) and an agent will attempt to speak with the occupa nts 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 dispatch the
necessary emergency services. ( → P. 452)WARNING ■

Front passenger occupant classification system precautions
Observe the following precau tions regarding the front passenger occupant classifica-
tion system.
Failure to do so may cause death or serious 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.●
Make sure the “AIR BAG OFF” indicator li ght is not illuminated when using the seat
belt extender for the front passenger seat. If the “AIR BAG OFF” indicator light is illu-
minated, disconnect the extender tongue from the seat belt buckle, and reconnect
the seat belt. Reconnect the seat belt extender after making sure the “AIR BAG ON”
indicator light is illuminated. If you use the seat belt extender while the “AIR BAG
OFF” indicator light is illuminated, the SRS airbags for the front passenger will not
activate, which could cause death or seri ous injury in the event of a collision.●
Do not apply a heavy load to the front pa ssenger seat or equipment (e.g. seatback
pocket). ●
Do not put weight on the front passenger 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 passenger seat.

For safety and security WARNING ■
Front passenger occupant classification system precautions ●
Do not recline the front passenger seatback so far that it touches the rear seat. This
may cause the “AIR BAG OFF” indicator ligh t to be illuminated, which indicates that
the SRS airbags for the front passenger will no t activate in the ev ent of a severe acci-
dent. If the seatback touches the rear seat, return the seatback to a position where it
does not touch the rear seat. Keep the fron t passenger seatback as upright as possi-
ble when the vehicle is moving. Reclining the seatback excessively may lessen the
effectiveness of the seat belt system.●
If an adult sits in the fron t passenger seat , the “AIR BAG ON” indicator light is illumi-
nated. If the “AIR BAG OFF” indicator is illuminated, ask the passenger 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 remain s illuminated, either ask the passenger to
move to the rear seat, or if that is not possible, move the fron t passenger seat fully
rearward. ●
When it is unavoidable to in stall a forward-facing child re straint system on the front
passenger seat, install the ch ild restraint system on the front passenger seat in the
proper order. ( → P. 62)●
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 indica te a malfunction of the front passenger
occupant classification system. In this cas e, contact your Lexus dealer immediately.●
Child restraint systems installe d on the second seat should not contact the front seat-
backs. ●
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 upholstery of the front seat.

LX570_OM_OM60Q78U_(U) WARNING ■
Child restraint precautions ●
For effective protection in automobile accidents and sudden stops, a child must be
properly restrained, using a seat belt or child restraint system depending on the age
and size of the child. Holding a child in your arms is not a su bstitute for a child restraint
system. In an accident, the child can be crushed against the windshield, or between
you and the vehicle’s interior. ●
Lexus strongly urges the use of a proper ch ild restraint system that conforms to the
size of the child, installed on the rear seat. According to accident statistics, the child is
safer when properly restrained in th e rear seat than in the front seat.●
Never install a rear-facing child restraint sy stem on the front passenger seat even if
the “AIR BAG OFF” indicator light is illuminated.
In the event of an accident, the force of the rapid inflation of the front passenger air-
bag can cause death or serious injury to the child if the rear-facing child restraint sys-
tem is installed on th e front passenger seat.●
A forward-facing child restraint system ma y be installed on the front passenger 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. Adjust the seatback as upright as possible and
always move the seat as far back as possible even if the “AIR BAG OFF” indicator
light is illuminated, because the front passenger airbag co uld inflate with considerable
speed and force. Otherwise, the chil d may be killed or seriously injured.●
Do not use the seat belt extender when inst alling a child restraint system on the front
or rear passenger seat. If in stalling a child restraint system with the seat belt extender
connected to the seat belt, th e seat belt will not securely hold the child restraint sys-
tem, which could cause death or serious injury to the chil d or other passengers in the
event of a sudden stop, sudden swerve or accident. ●
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, side and rear pillars or roof side rails from which the
SRS side airbags or SRS curtain shield airbags deploy even if the child is seated in the
child restraint syst em. It is dangerous if the SRS side airbags and curtain shield air-
bags inflate, and the impact could caus e death or serious injury to the child.●
Make sure you have complied with all insta llation instructions provided by the child
restraint manufacturer and that the system is properly secured. If it is not secured
properly, it may cause death or serious inju ry to the child in the event of a sudden
stop, sudden swerve or accident.

LX570_OM_OM60Q78U_(U) WARNING ■
When installing a booster seat
To prevent the belt from going into ALR lock mode, do not fully extend the shoulder
belt. ALR mode causes the belt to tighten on ly. This could cause injury or discomfort to
the child. ( → P. 34)■
When installing a child restraint system
Follow the directions given in the child rest raint system installation manual and fix the
child restraint system securely in place.
If the child restraint system is not correctly fixed in place, the child or other passengers
may be seriously injured or even killed in th e event of sudden braking, sudden swerving
or an accident.
●
When installing a child restraint system on the second center seat, adjust both seat
cushions to the same position and align bo th seatbacks at the sa me angle. The seat-
backs must be adjusted to the same angle. Otherwise, the child restraint system can-
not be securely restrained an d this may cause death or seri ous injuries in the event of
sudden braking, sudden swerving or an accident. ●
When using the LATCH anchors for a child restraint system, move the seat as far
back as possible, with the seatback close to the child restraint system.●
If the driver’s seat interferes with the child
restraint system and prevents it from being
attached correctly, atta ch the child restraint
system to the right-hand rear seat. ●
Adjust the front passenger seat so that it does
not interfere with the child restraint system. ●
Vehicles with third seat s: Child restraint sys-
tem installed on the thir d seat should not con-
tact the second seatbacks. ●
Only put a forward-faci ng child restraint sys-
tem on the front seat when unavoidable.
When installing a forward-facing child
restraint system on the front passenger seat,
move the seat as far back as possible even if
the “AIR BAG OFF” indicator light is illumi-
nated. Failure to do so may result in death or
serious injury if the airbags deploy (inflate).
