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 cxi.
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 cxlvii.

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 are suffers a
severe impact from the side.
Always wear your seat belts properly.
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.

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 se rious 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.
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.

This indicator comes on when the ignition key is turned to
the “ON” position. It goes off after about 6 seconds. This
means the SRS side airbags and curtain shield airbags are
operating properly.
This warning light system monitors the airbag sensor
assembly, front airbag sensors, side and curtain shield airbag
sensor assemblies, curtain shield airbag sensor assemblies,
driver’s seat position sensor, driver’s seat belt buckle switch,
front passenger occupant classification system, “AIRBAG
OFF” indicator light, “AIRBAG ON” indicator light, front
passenger’s seat belt buckle switch, seat belt pretensioner
assemblies, inflators, warning light, interconnecting wiring and
power sources. (For details, see “Service reminder indicators
and warning buzzers” on page lviii for instructions.) If any of the following conditions occurs, this indicates a
malfunction of the airbags or seat belt pretensioners. Contact
your Lexus dealer as soon as possible.
The light does not come on when the ignition key is turned
to the “ON” position or remains on for more than 6 seconds.
The light comes on while driving.
The SRS warning light and “AIRBAG OFF” indicator light will
be illuminated if there is a malfunction in the front passenger
occupant classification system.

FRONT PASSENGER OCCUPANTCLASSIFICATION SYSTEM
Your vehicle is equipped with a front passenger occupant
classification system. This system detects the conditions
1 — 4 in the table shown below, and based on these
conditions activates or deactivates the following
systems;
Front passenger airbag
Side airbag on the front passenger seat
Front passenger’s seat belt pretensioner
The system monitors the weight and load on the front
passenger seat, and the seat belt buckle switch in
determining conditions correctly, do not do any of the
following:
Apply a heavy load to the front passenger seat or equipment
(e.g. seatback pocket).
Attach a commercial seatback table, etc. to the front
passenger seat seatback.
Put weight on the front passenger seat by putting your
hands or feet on the seatback from the rear passenger seat.
The “AIRBAG OFF” indicator light will be illuminated
when the ignition switch is in the “ON” position and a child
restraint system is in the front passenger seat (see
table condition 2). This indicates that in the event of a
severe frontal or passenger’s side impact, the front
passenger airbag and side airbag on the front passenger
seat are deactivated and will not deploy.
If the front passenger occupant classification system
determines that a person of adult size sits in the front
passenger seat but the “AIRBAG OFF” indicator light is
illuminated, one of the following is likely to have occurred:
A rear passenger lifts the front passenger seat cushion with
their legs.
Objects are placed under the front passenger seat.
The front passenger seat seatback is in contact with the rear
seat.

OCCUPANT RESTRAINT SYSTEM
cxlivTo ensure the system correctly detects an adult sitting in the
front passenger seat, make sure the above do not occur.
Make
sure the “AIRBAG ON” indicator light is illuminated when
an adult is seated in the front passenger seat. If the “AIRBAG
OFF” indicator light is illuminated, ask the passenger to sit up
straight, well back in the seat, and with the seat belt worn
correctly. If the “AIRBAG OFF” indicator light still remains
illuminated, either ask the passenger to move to the rear seat,
or if that is not possible, move the front passenger seat fully
rearward.
The “AIRBAG OFF” and “AIRBAG ON” indicator lights will
be initially illuminated when the ignition switch is turned
to the “ON” position. It will remain for about four seconds
and then go off. After the two seconds, the front
passenger occupant classification system operates and
judges which indicator light to turn on.
The SRS warning light and “AIRBAG OFF” indicator light
will be illuminated if there is a malfunction in the front
passenger occupant classification system.
