OCCUPANT RESTRAINT SYSTEM
130
Do not sit on the edge of the seat or lean over the
dashboard when the vehicle is in use, since the front
passenger airbag could inflates with considerable
speed and force. Anyone who is up against, or very
close to, an airbag when it inflates, can be killed or
seriously injured. Sit up straight and well back in the
seat, and always use your seat belt properly.

OCCUPANT RESTRAINT SYSTEM
132
Do not put anything or any part of your body on or in
front of the dashboard or steering wheel pad that
houses the front airbag system. They might restrict
inflation or cause death or serious injury as they are
projected rearward by the force of the deploying
airbags. Likewise, the driver and front passenger
should not hold objects in their arms or on their
knees.

OCCUPANT RESTRAINT SYSTEM
133
Do not modify or remove any wiring. Do not modify,
remove, strike or open any components, such as the
steering wheel pad, steering wheel, column cover,
front passenger airbag cover, front passenger airbag
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.
Installation of electronic devices such as a mobile
two-way radio, cassette tape player or compact disc
player
Modification of the suspension system
Modification of the front end structure
Attachment of a grille guard (bull bar, kangaroo bar,
etc.), snowplow, winches or any other equipment to
the front end
Repairs made on or near the front fenders, front end
structure, console, steering column, steering wheel
or dashboard near the front passenger airbag

In the following cases, contact your Lexus dealer as soon as
possible:
The SRS front airbags have been inflated.
The front of the vehicle (shaded in the illustration) was
involved in an accident that was not severe enough to cause
the SRS front airbags to inflate.The pad section of the steering wheel or front passenger
airbag cover (shaded in the illustration) is scratched,
cracked, or otherwise damaged.

SRS SIDE AIRBAGS AND CURTAIN
SHIELD AIRBAGS
The SRS (Supplemental Restraint System) side airbags
and curtain shield airbags are designed to provide further
protection for the driver, front passenger and rear outside
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 side airbags help reduce injuries
mainly to the driver's or front passenger's torso and the SRS
curtain shield airbags help reduce injuries mainly to the
driver's, front passenger's or rear outside passenger's head.The side airbag on the passenger seat will not activate if there
is no passenger sitting in the front passenger seat. However,
the 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 the occupant in the seat. (As for the front
passenger occupant classification system, see Front
passenger occupant classification systemº on page 152.)
The SRS curtain shield airbag on the passenger side are
activated even with no passenger in the front seat or rear
outside seat.
The curtain shield airbags may activate even when the side
airbags are not activated.
Always wear your seat belt properly.
Your vehicle is equipped with a crash sensing and diagnostic
module, which will record the use of the seat belt restraint
system by the driver and front passenger when the SRS side
airbags are inflated.

OCCUPANT RESTRAINT SYSTEM

CAUTION
The SRS side airbag and curtain shield airbag system
is designed only as a supplement to the primary
protection of the driver and front passenger and rear
outside 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 beltsº on page 112.
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 airbags 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
restraintº on page 156.

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
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.

OCCUPANT RESTRAINT SYSTEM
141 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 outside passengers must:
Wear their seat belts properly.
Remain properly seated with their backs upright and
against the seats at all times.
