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 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 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. 370)WARNING ■

RC F_U 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 may 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.

RC F_U WARNING ■
Front passenger occupant classification system precautions ●
Do not recline the front passeng er seatback so far that it  touches a rear seat. This may
cause the “AIR BAG OFF” indicator light to  be illuminated, whic h indicates that the
SRS airbags for th e front passenger will no t activate in the even t 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 effec-
tiveness 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. 60)●
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 insta lled on the rear se at 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. ●
Do not place anything between the cons ole box and front passenger seat. Other-
wise, the system may not de tect the front passenger pr operly, leading to improper
operation of the airbags. ●
Adjust the front passenger seat so that the head restraint does not touch the ceiling. If
the head restraint is left in contact with the ceiling, the system may not detect the front
passenger properly, leading to improper operation of the airbags.

RC F_U WARNING ■
When installing a child restraint system
Observe the following when installing child re straint system to the front passenger seat
if it is unavoidable. The front passenger SR S airbag inflates with considerable speed
and force that if not observed may lead  to death or serious injury to the child.●
Never install a rear-facing child restraint sy stem on the front passenger seat even if
the “AIR BAG OFF” indicator lig ht is illuminated. In the even t of an accident, the force
of the rapid inflation of the front passenger  airbag can cause death or serious injury to
the child if the rear-facing ch ild restraint system is inst alled on the 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.
●
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 pillars or  roof side rails from  which the SRS side air-
bags or SRS curtain shield airbags 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 en sure that the 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 coul d fall off the child’s shoulder.●
A forward-facing child restraint system may
be installed on the front passenger seat only
when it is unavoidable. When installing a for-
ward-facing child restrain t system on the front
passenger seat, adjust the seatback to the
most upright position, move the seat to the
rearmost position, and raise the seat to the
highest position, even if the “AIR BAG OFF”
indicator light is illuminated. 
If the head restraint interferes with the instal-
lation of the child re straint system, and the
head restraint can be  removed, remove the
head restraint.
