CAUTION
■SRS airbag precautions
●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 the parts where the SRS side airbags
inflate as they may interfere with inflation of the 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 significant levels of force to the area of the SRS airbag
components.
Doing so can cause the SRS airbags to malfunction.
●Do not touch any of the component parts immediately after the SRS airbags have
deployed (inflated) as they may be hot.
●If breathing becomes difficult after the SRS airbags have deployed, open a door
or window to allow fresh air in, or leave the vehicle if it is safe to do so. Wash off
any residue 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, center and rear pillar garnishes, are damaged or cracked, have them
replaced by your Lexus dealer.

ing).
■Operating conditions when the “RSCA OFF” indicator is on
●The curtain shield airbag and seat belt pretensioner will not activate in a vehicle
rollover.
●The curtain shield airbag will activate in a severe side impact.
●The seat belt pretensioner will activate in a severe frontal or side collision.

CAUTION
■Front passenger occupant classification system precautions
●Make sure the “AIR BAG OFF” indicator light is not illuminated when using the
seat belt extender for the front passenger seat. If the “AIR BAG OFF” indicator
light is illuminated, 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 front passenger airbag
and front passenger knee airbag 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 pocket).
●Do not put weight on the front passenger seat by putting your hands or feet on
the front passenger seat seatback from the second seat.
●Do not let a second seat 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.
●Do not recline the front passenger seatback so far that it touches a second seat.
This may cause the “AIR BAG OFF” indicator light to be illuminated, which indi-
cates that the passenger’s airbags will not deploy in the event of a severe acci-
dent. If the seatback touches the second seat, return the seatback to a position
where it does not touch the second seat. Keep the front passenger seatback as
upright as possible when the vehicle is moving. Reclining the seatback exces-
sively may lessen the effectiveness of the seat belt system.

■Selecting an appropriate child restraint system
●Use a child restraint system appropriate for the child until the child becomes
large enough to properly wear the vehicle’s seat belt.
●If the child is too large for a child restraint system, sit the child on a rear seat and
use the vehicle’s seat belt. (→P. 8 5 )
CAUTION
■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 substitute for a
child restraint system. In an accident, the child can be crushed against the wind-
shield, or between you and the vehicle’s interior.
●Lexus strongly urges the use of a proper child 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 the rear seat than in the front seat.
●Never install a rear-facing child restraint system on the front passenger seat even
if the “AIR BAG OFF” indicator light illuminated. In the event of an accident, the
force of the rapid inflation of the front passenger airbag can cause death or seri-
ous injury to the child if the rear-facing child restraint system is installed on the
front passenger seat.
