1Collision from the front
2Collision from the rear
3Vehicle rollover
The SRS side airbags and curtain shield airbags are not
generally designed to inflate if the vehicle is involved in a
front or rear collision, if it rolls over, or if it is involved in
a low speed side collision.

6Airbag sensor assembly
The SRS side airbag and curtain shield airbag system consists
mainly of the above components, and their locations are
shown in the illustration.
The SRS side airbag and curtain shield airbag system is
controlled by the airbag sensor assembly. The airbag sensor
assembly consists of a safing sensor and airbag sensor.

In a severe side impact, the side and curtain shield airbag
sensor and/or the curtain shield airbag sensor trigger(s) the
side airbag inflators and/or the curtain shield airbag inflators.
At this time a chemical reaction in the inflators quickly fills the
airbags with non
−toxic gas to help restrain the lateral motion
of the occupants.
When the airbags inflate, they produce a fairly loud noise and
release some smoke and residue along with non −toxic gas.
This does not indicate a fire. This smoke may remain inside
the vehicle for some time, and may cause some minor irritation
to the eyes, skin or breathing. Be sure to wash off any residue
as soon as possible to prevent any potential skin irritation with
soap and water. If you can safely exit from the vehicle, you
should do so immediately.
Deployment of the airbags happens in a fraction of a second,
so the airbags must inflate with considerable force. While the
system is designed to reduce serious injuries, it may also
cause minor burns or abrasions and swelling.
Front seats as well as parts of the front and rear pillars, and roof
side rail may be hot for several minutes, but the airbags
themselves will not be hot. The airbags are designed to inflate
only once.
CAUTION
SRS side airbags and curtain shield airbags inflate with
considerable force. To reduce the possibility of death
or serious injury when they inflate, the driver, front
passenger and rear outboard passengers must:
Wear their seat belts properly.
Remain properly seated with their backs upright and
against the seats at all times.

16L344
Do not allow anyone to lean against the door when
the vehicle is in use, since the side airbag and curtain
shield airbag could inflate with considerable speed
and force. Otherwise, he/she may be killed or
seriously injured. Special care should be taken
especially when you have a small child in the vehicle.
Sit up straight and well back in the seat, distributing
your weight evenly in the seat. Do not apply
excessive weight to the outer side of the seats with a
side airbag and to the front pillar, rear pillar and roof
side rail with a curtain shield airbag.
16L583
Do not allow anyone to get his/her head close to the
area where the side airbag and curtain shield airbag
inflate, since these airbags could inflate with
considerable speed and force. Otherwise, he/she
may be killed or seriously injured. Special care
should be taken especially when you have a small
child in the vehicle.
Do not allow anyone to kneel on the passenger seat,
facing the passenger’s side door, since the side
airbag and curtain shield airbag could inflate with
considerable speed and force. Otherwise, he/she
may be killed or seriously injured. Special care
should be taken especially when you have a small
child in the vehicle.

16L623
Do not allow anyone to get his/her head or hands out
of windows, since the curtain shield airbags could
inflate with considerable speed and force.
Otherwise, he/she may be killed or seriously injured.
Special care should be taken especially when you
have a small child in the vehicle.
16L640
Do not attach a cupholder or any other device or
object on or around the door. When the side airbag
inflates, the cupholder or any other device or object
will be thrown with great force, or the side airbag may
not activate correctly, resulting in death or serious
injury. Likewise, the driver and front passenger
should not hold objects in their arms or on their
knees.

16L348
Do not attach a microphone or any other device or
object around the area where the curtain shield
airbag activates such as on the windshield glass,
side door glass, front and rear pillars, roof side rail
and assist grips. When the curtain shield airbag
inflates, the microphone or other device or object will
be thrown away with great force or the curtain shield
airbag may not activate correctly, resulting in death
or serious injury.
Do not hook a hanger , heavy or sharp pointed objects
on the coat hook. If the curtain shield airbag inflates,
those items will be thrown away with great force or
the curtain shield airbag may not activate correctly,
resulting in death or serious injury. When you hang
clothes, hang them on the coat hook directly.
Do not use seat accessories which cover the parts
where the side airbags inflate. Su ch accessories may
prevent the side airbags from activating correctly,
causing death or serious injury.
Do not modify or replace the seats or upholstery of
the seats with side airbags. Such changes may
prevent the side airbag system from activating
correctly, disable the system or cause the side
airbags to inflate accidentally, resulting in death or
serious injury.
Do not disassemble or repair the front and rear pillars
and roof side rails containing the curtain shield
airbags. Such changes may disable the system or
cause the curtain shield airbags to inflate
accidentally, resulting in death or serious injury.
Failure to follow these instructions can result in death
or serious injury. Consult your Lexus dealer about any
repair and modification.

In the following cases, contact your Lexus dealer as soon as
possible:
Any of the SRS side airbags and curtain shield airbags have
been inflated.
The portion of the doors (shaded in the illustration) was
involved in an accident that was not severe enough to cause
the SRS side airbags and curtain shield airbags to inflate.
The surface of the seats with the side airbag (shaded in the
illustration) is scratched, cracked, or otherwise damaged.
The portion of the front pillars, rear pillars or roof side rail
garnishes (padding) containing the curtain shield airbags
inside (shaded in the illustration) is scratched, cracked, or
otherwise damaged.
NOTICE
Do not disconnect the battery cables before contacting
your Lexus dealer.
CHILD RESTRAINT
Child restraint precautions
Lexus strongly urges the use of appropriate child
restraint systems for children.
The laws of all 50 states in the U.S.A. and Canada now require
the use of a child restraint system.
Your vehicle conforms to SAE J1819.
If a child is too large for a child restraint system, the child should
sit in the rear seat and must be restrained using the vehicle’s
seat belt. See “Seat belts” on page 168 for details.
CAUTION
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 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
windshield, or between you and the vehicle’s interior.
Lexus strongly urges use of a proper child restraint
system which 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.
