■SRS airbag deployment conditions (SRS side and curtain shield airbags)
●The SRS side and curtain shield airbags will 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. [1500 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]).
●The SRS curtain shield airbags may also deploy in the event of a severe frontal colli-
sion.
■Conditions under which the SRS airbags may deploy (inflate), other than a collision
(SRS front airbags, SRS curtain shield airbag and SRS seat cushion airbag)
The SRS front airbags, SRS curtain shield airbag and SRS seat cushion airbag may
also deploy if a serious impact occurs to the underside of your vehicle. Some exam-
ples are shown in the illustration.
■Types of collisions that may not deploy the SRS airbags (SRS front airbags and SRS
seat cushion airbag)
The SRS front airbags and SRS seat cushion airbag do not generally inflate if the
vehicle is involved in a side or rear collision, if it rolls over, or if it is involved in a low-
speed frontal collision. But, whenever a collision of any type causes sufficient for-
ward deceleration of the vehicle, deployment of the SRS front airbags and SRS seat
cushion airbag may occur.
●Hitting a curb, edge of pavement or hard
surface
●Falling into or jumping over a deep hole
●Landing hard or falling
●Collision from the side
●Collision from the rear
●Vehicle rollover

■Types of collisions that may not deploy the SRS airbags (SRS side and curtain shield
airbags)
The SRS side and curtain shield airbags may not activate if the vehicle is subjected to
a collision from the side at certain angles, or a collision to the side of the vehicle body
other than the passenger compartment.
The SRS side airbags do not generally inflate if the vehicle is involved in a frontal or
rear collision, if it rolls over, or if it is involved in a low-speed side collision.
The SRS curtain shield airbags do not generally inflate if the vehicle is involved in a
rear collision, if it rolls over, or if it is involved in a low-speed side or low-speed frontal
collision.

■When to contact your Lexus dealer
In the following cases, the vehicle will require inspection and/or repair. Contact your
Lexus dealer as soon as possible.
●Any of the SRS airbags have been inflated.
●The front of the vehicle is damaged or
deformed, or was involved in an accident
that was not severe enough to cause the
SRS airbags to inflate.
●A portion of a door is damaged or
deformed, or the vehicle was involved in an
accident that was not severe enough to
cause the SRS side and curtain shield air-
bags to inflate.
●The pad section of the steering wheel, dash-
board near the front passenger airbag or
lower portion of the instrument panel is
scratched, cracked, or otherwise damaged.
●Relaxation seat: The seat cushion surface is
scratched, cracked, or otherwise damaged.

CAUTION
■Front passenger occupant classification system precautions
Observe the following precautions regarding the front passenger occupant classi-
fication 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 passen ger seat. If the “AIR BAG OFF” indicator
light is illuminated, discon nect the extender tongue from the seat belt buckle,
then reconnect the seat belt. Reconnect th e 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
passenger may not activate correctly, which could cause death or serious injury
in the event of a collision.
●Do not apply a heavy load to the front passenger seat or equipment (e.g. seat-
back pockets or armrest).
●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.

CAUTION
■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, which indicates
that the passenger’s airbags will not deploy in the event of a severe accident. If the
seatback touches the rear seat, return th e 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
effectiveness of the seat belt system.
●If an adult sits in the front passenger seat, the “AIR BAG ON” indicator light is illu-
minated. If th e “AIR BAG OFF” indicator is illumi nated, ask the passenger to sit
up straight, well back in the seat, feet on the floor, and with the seat belt worn cor-
rectly. If the “AIR BAG OFF” indicator stil l remains illuminated, either ask the pas-
senger 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 rest raint system on the front passenger seat
in the proper order. ( P. 66)
●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 indi cate a malfunction of the detection sys-
tem. In this case, 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 cushion or seat cover, that covers the seat
cushion surface.
●Do not modify or replace the upholstery of the front seat.
