RC F_U Your vehicle is equipped with ADVA NCED AIRBAGS designed based on the
US motor vehicle safety standards (F MVSS208). 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 motion of the occupants.SRS airbag system components

RC F_U WARNING ■
SRS airbag precautions ●
Do not hang coat hangers or hard objects on the coat hooks. All of these items could
become projectiles and may cause death or serious injury, should the SRS curtain
shield airbags deploy. ●
If a vinyl cover is put on the area where the SRS knee airbag will deploy, be sure to
remove it. ●
Do not use seat accessories which cover th e parts where the SRS side airbags inflate
as they may interfere with inflation of th e airbags. Such accessories may prevent the
side airbags from activating correctly, disable the system or cause the side airbags to
inflate accidentally, resulting in death or serious injury.●
Do not strike or apply signif icant levels of force to the area of the SRS airbag compo-
nents.
Doing so can cause the SRS airbags to malfunction. ●
Do not touch any of the component part s immediately after the SRS airbags have
deployed (inflated) as they may be hot. ●
If breathing becomes difficult after the SR S 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, the SRS front airbags for the front passenger
may not deploy in the event of a collision.

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 ma y 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 seat, 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 sy stem should only be inst alled on the front passenger
seat when it is unavoidable. (  P. 58)
* 6
: In case the indicator light is not illuminated, consult this manual on how to install the
child restraint system properly. (  P. 60)Indicator/

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.
