RX350_U_OM48E90U 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 sen-
sors etc. shown in the system compon ents 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 non-toxic gas to
help restrain the moti on of the occupants.SRS airbag system components

SRS airbag precautions ●
If breathing becomes difficult after the SRS airbags have deployed, open a door or
window to allow fresh air in, or leave the vehicl e if it is safe to do so. Wash off any resi-
due as soon as possible to prevent skin irritation. ●
If the areas where the SRS airbags are stored, such as the steering wheel pad and
front and rear pillar garnishes, are damaged or cracked, have them replaced by your
Lexus dealer. ●
Do not place anything, such as a cushion, on the front passenger’s seat. Doing so will
disperse the passenger’s weight, which prevents the sensor from detecting the pas-
senger’s weight properly. As a result, th e SRS front airbags for the front passenger
may not deploy in the event of a collision. ■
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 de ath or serious injury.●

There is a malfunction in the system
* 1
: The system judges a person of adult size as an adult. When a smaller adult sits in the
front passenger seat, the system may not recognize him/her as an adult depending on
his/her physique and posture.
* 2
: In the event the front passenger is wearing a seat belt.
* 3
: In the event the front passenger does not wear a seat belt.
* 4
: For some children, child in se at, child in booster seat or child in convertible seat, the
system may not recognize him/her as a child. Factors which may affect this can be the
physique or posture.
* 5
: Never install a rear-facing child restraint system on the front passenger seat. A for-
ward-facing child restraint system should on ly be installed on the front passenger seat
when it is unavoidable. (  P. 5 7 )
* 6
: In case the indicator light is not illuminated, consult this manual on how to install the
child restraint system properly. (  P. 5 9 )Indicator/

Front passenger occupant classification system precautions
Observe the following precautions 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 th e seat belt extender while the “AIR BAG
OFF” indicator light is illumi nated, the SRS airbags for the front passenger will not
activate, which could cause death or serious 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 se at 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.

Front passenger occupant classification system precautions ●
Do not recline the front passenger 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 the front passenger will not activate in the event 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 pa ssenger 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 front 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 remains illuminated, either ask the passenger to
move to the rear seat, or if that is not possible, move the front passenger seat fully
rearward. ●
When it is unavoidable to install a forward- facing child restraint system on the front
passenger seat, install the child restraint sy stem on the front passenger seat in the
proper order. (  P. 5 9 )●
Do not modify or remove the front seats. ●
Do not kick the front passenger seat or subj ect it to severe impact. Otherwise, the
SRS warning light may come on to indicat e a malfunction of the front passenger
occupant classification system. In this ca se, contact your Lexus dealer immediately.●
Child restraint systems installed on the rear seat should not contact the front seat-
backs. ●
Do not use a seat accessory, such as a cu shion and seat cover, that covers the seat
cushion surface. ●
Do not modify or replace the upholstery of the front seat.
