Do not sit on the edge of the seat or lean against the
dashboard when the vehicle is in use, since the front
passenger airbag could inflate 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.

 Lexus strongly recommends that all infants and
children be placed in the rear seat of the vehicle and
be properly restrained.
 Do not allow a child to stand up or kneel on the front
passenger seat, since the front passenger airbag
could inflate with considerable speed and force.
Otherwise, the child may be killed or seriously
injured.
 Do not hold a child on your lap or in your arms. Use
a child restraint system in the rear seat. For
instructions concerning the installation of a child
restraint system, see “Child restraint” on page 199.

Do not put anything or any part of your body on or in
front of the dashboard, lower portion of instrument
panel, steering wheel pad that houses the front
airbag system or in the areas where the SRS knee
airbags will inflate. 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.
 If a vinyl cover is put on the area where the SRS knee
airbag will deploy, be sure to remove it.
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, strike or open any components, such as the
steering wheel pad, steering wheel, column cover,
dashboard near the front passenger airbag, front
passenger airbag cover, front passenger airbag,
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.

Do not attach any heavy, sharp or hard objects such
as keys or accessories to the ignition key. The
objects may restrict the SRS knee airbag inflation or
be thrust into the driver’s seat area by the force of the
deploying airbag, causing a danger.
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
twoway radio, cassette tape player or CD 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,
lower portion of instrument panel or dashboard near
the front passenger airbag.

The indicator comes on when the ignition switch is turned
to the “ON” position. It goes off after about 6 seconds.
This means the SRS front 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,
occupant detection sensor, 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 82.) 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.

When the ignition switch is turned to the “ON” position, the
light does not come on or remains on for more than 6
seconds.
 The light comes on while driving.

SRS SIDE AIRBAGS AND CURTAINSHIELD AIRBAGS
16L620
 1Curtain shield airbag 2Side airbag
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 side airbags help reduce injuries
mainly to the driver’s or front passenger’s chest, and the SRS
curtain shield airbags help reduce injuries mainly to the
driver’s, front passenger’s or rear outboard passenger’s head. The SRS 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 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.
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 168.

OCCUPANT RESTRAINT SYSTEMS

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
restraint” on page 199 .

 1 Collision 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.

OCCUPANT RESTRAINT SYSTEMS
193
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.
