Do not attach any objects except Lexus genuine
parts in the area where the SRS knee airbag for the
front passenger will inflate. When using an ashtray
or auxiliary box on the front passenger’s console
box, be sure to keep it closed. The attached object, or
opened ashtray or auxiliary box might restrict
inflation of the airbag or be thrown away by the force
of the deploying airbag, causing a danger.
 Do not modify or remove any wiring. Do not modify,
remove, st rike or open any components, such as the
steering wheel pad, steering wheel, column cover,
dashboard near the front passenger airbag, front
passenger airbag cover, knee airbags or airbag
sensor assembly. Doing so may prevent the front
airbag system from activating correctly, cause
sudden activation of the system or disable the
system, which could result 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.NOTICE
Do not perform any of the following changes without
consulting your Lexus dealer. Such changes can
interfere with proper operation of the SRS front airbag
system in some cases.

SRS SIDE AIRBAGS AND CURTAINSHIELD AIRBAGS
G16028
 1Curtain shield airbag
2Front side airbag
3Rear side airbag (for some models)
The SRS (Supplemental Restraint System) side airbags
and curtain shield airbags are designed to provide further
protection for the driver, front passenger and rear
outboard passengers in addition to the primary safety
protection provided by the seat belts. In response to a severe side impact, the SRS side airbags and
curtain shield airbags work with the seat belts to help reduce
injury by inflating. The SRS front side airbags help reduce
injuries mainly
to the driver’s or front passenger’s chest. The
SRS curtain shield airbags help reduce injuries mainly to the
driver’s, front passenger’s or rear outboard passenger’s head.
The SRS front side airbag on the passenger seat will not
activate if there is no passenger sitting in the front passenger
seat. However, the front side airbag on the passenger seat
may deploy if luggage is put in the seat, or the seat belt is
buckled up, regardless of the presence of an occupant in the
seat.
The SRS curtain shield airbags may activate even when the
side airbags are not activated.
Always wear your seat belt properly.
Vehicles equipped with SRS rear side airbags—
The SRS rear side airbags help reduce injuries mainly to the
rear outboard passenger’s chest.
The SRS rear side airbags will activate regardless of the
presence of the occupant.

CAUTION
The SRS side airbag and curtain shield airbag system
is designed only as a supplement to the primary
protection of the driver, front passenger and rear
outboard passenger seat belt systems. To ensure
maximum protection in an accident, the driver and all
passengers in the vehicle must wear their seat belts
properly. Wearing a seat belt properly during an
accident reduces the chances of death or serious
injury or being thrown out of the vehicle. For
instructions and precautions concerning the seat
belt system, see “Seat belts” on page 151.
 Do not allow anyone to lean his/her head or any part
of his/her body against the door or the area of the
seat, front pillar, rear pillar or roof side rail from which
the SRS side airbag and curtain shield airbag deploy
even if he/she is a child seated in the child restraint
system. It is dangerous if the SRS side airbag and
curtain shield airbag inflate, and the impact of the
deploying airbag could cause death or serious injury
to the occupant.
 Improperly seated and/or restrained infants and
children can be killed or seriously injured by the
deploying airbags. An infant or child who is too small
to use a seat belt should be properly secured using
a child restraint system. Lexus strongly
recommends that all infants and children be placed
in the rear seats of the vehicle and properly
restrained. The rear seats are the safest for infants
and children. For instructions concerning the
installation of a child restraint system, see “Child
restraint” on page 182 .

 1Collision from the side to the vehicle body other
than the passenger compartment
2Collision from the side at an angle
The SRS side airbag and curtain shield airbag system 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 as
shown in the illustration.
The SRS side airbags and curtain shield airbags are designed
to inflate when the passenger compartment area suffers a
severe impact from the side.
Always wear your seat belts properly.
G16030
 1 Collision 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 lowspeed side collision.

Rear side airbag modules (airbag and inflator)
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 (and outboard rear) seats as well as the parts of the front
and rear pillars, and roof side rail may be hot for several
minutes, but the airbags themselves will 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.
G16137
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.

G16033
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 front passenger
(and outboard rear )seat, facing the front passenger’s
side (and rear outboard 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.
G16034
 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

G16035a
Do not attach a cupholder or any other device or
object on or around the doors. When the side airbag
inflate, 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.
G16036
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.
