SRS airbag system components
The main SRS airbag system components are shown above. The SRS air-
bag system is controlled by the airbag sensor assembly. 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.Airbag manual on-off switch

CAUTION
■SRS airbag precautions
●If a vinyl cover is put on the area where the SRS knee airbags 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 and rear pillar garnishes, are damaged or cracked, have them replaced by
any authorized Lexus dealer or repairer, or another duly qualified and equipped
professional.

CAUTION
■Child restraint precautions
●Never use a rear-facing child restraint system on the front passenger seat when
the airbag manual on-off switch is on. (→P. 1 6 3 )
In the event of an accident, the force of the rapid inflation of the front passenger
airbag can cause death or serious injury to the child.
●A forward-facing child restraint system may be allowed to 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. Adjust the seat-
back as upright as possible and always move the seat as far back as possible
because the front passenger airbag could inflate with considerable speed and
force. Otherwise, the child may be killed or seriously injured.
●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 and rear pillars or roof side rails from which the
SRS side airbags or SRS curtain shield airbags deploy even if the child is seated in
the child restraint system. It is dangerous if the side airbags and curtain shield air-
bags inflate, and the impact could cause death or serious injury to the child.
●Make sure you have complied with all installation instructions provided by the
child restraint manufacturer and that the system is properly secured. If it is not
secured properly, it may cause death or serious injury to the child in the event of a
sudden stop, sudden swerve or an accident.
■When children are in the vehicle
Do not allow children to play with the seat belt. If the seat belt becomes twisted
around a child’s neck, it may lead to choking or other serious injuries that could
result in death.
If this occurs and the buckle cannot be unfastened, scissors should be used to cut
the belt.
■When the child restraint system is not in use
●Keep the child restraint system properly secured on the seat even if it is not in use.
Do not store the child restraint system unsecured in the passenger compartment.
●If it is necessary to detach the child restraint system, remove it from the vehicle or
store it securely in the luggage compartment. This will prevent it from injuring
passengers in the event of a sudden stop, sudden swerve or an accident.

CAUTION
■When installing a child restraint system
●Never use a rear-facing child restraint sys-
tem on the front passenger seat when the
airbag manual on-off switch is on.
(→P. 1 6 3 )
The force of the rapid inflation of the front
passenger airbag can cause death or seri-
ous injury to children in the event of an
accident.
There is a label(s) on the passenger side
sun visor, indicating it is forbidden to attach
a rear-facing child restraint system to the
front passenger seat.
Details of the label(s) are shown in the illus-
tration below.
