The SRS airbag system mainly consists of the above
components, and their locations are shown in the illustration.
The airbag sensor assembly consists of a safing sensor and
airbag sensors.

The front airbag sensors constantly monitor the forward
deceleration of the vehicle. If an impact results in a forward
deceleration beyond the designed threshold level, the system
triggers the airbag inflators. In a severe side impact, the side
and curtain shield airbag sensor triggers the side and curtain
shield airbag inflator. At this time a chemical reaction in the
inflators very quickly fills the airbags with non±toxic gas to help
restrain the forward or lateral motion of the occupants. The
airbags then quickly deflate, so that here is no obstruction of
the driver's vision should it be necessary to continue driving.
When the airbags inflate, they produce a 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 physically and safely exit the
vehicle after a collision, you should do so at the first
opportunity.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, primarily to the
head and chest, it may also cause other, less severe injuries
to the face, chest, arms and hands. These are usually in the
nature of minor burns or abrasions and swelling, but the force
of a deploying airbag can cause more serious injuries,
especially if an occupant's hands, arms, chest or head is in
close proximity to the airbag module at the time of deployment.
This is why it is important for the occupant to; avoid placing any
object or part of the body between the occupant and the airbag
module; sit straight and well back into the seat; wear the
available seat belt properly; and sit as far as possible from the
airbag module, while still maintaining control of the vehicle.
Parts of the airbag module (steering wheel hub, airbag cover
and inflator) may be hot for several minutes after deployment,
so do not touch! The airbags inflate only once. The windshield
may be damaged by absorbing some of the force of the
inflating airbag.

CAUTION
The SRS airbag system is designed only as a
supplement to the primary protection of the driver
side and front passenger side seat belt systems. The
front seat occupants can be killed or seriously
injured by the inflating airbags if they do not wear the
available seat belts properly. During sudden braking
just before a collision, an unrestrained driver or front
passenger can move forward into direct contact with
or close proximity to the airbag which may then
deploy during the collision. 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 ºSeat beltsº on page 88.
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 seat of the vehicle and properly restrained.
The rear seat is the safest for infants and children.
For instructions concerning the installation of a child
restraint system, see ºChild restraintº on page 111 .
16G057a
Never put a rear±facing child restraint system on the
front passenger seat because the force of the rapid
inflation of the front passenger airbag can cause
death or serious injury to the child.

16G059±2

Move seat fully back
A forward±facing child restraint system should be
allowed to be put on the front passenger seat only
when it is unavoidable. Always move the seat as far
back as possible, because the force of the deploying
front passenger airbags could cause death or
serious injury to the child.
Do not allow the child to lean against the front door
or around the front door even if the child is seated in
a child restraint system. It is dangerous if the side
airbag and curtain shield airbag inflate, because the
impact could cause death or serious injury to the
child.
For instructions concerning the installation of a child
restraint system, see ºChild restraintº on page 111.
16G029a
Do not sit on the edge of the seat or lean against the
dashboard when the vehicle is in use, since the front
passenger airbags inflate with considerable speed
and force. Otherwise, you may be killed or seriously
injured. Sit up straight and well back in the seat, and
always use your seat belt properly.

The surface of the seats with the side airbags or the pad
section of the steering wheel or front passenger airbag
cover (shaded in the illustration) is scratched, cracked, or
otherwise damaged.
The portion of the front pillar and roof side rail garnish
(padding) containing the curtain shield airbags inside
(shaded in the illustration) is scratched, cracked, or
otherwise damaged.CHILD RESTRAINT
Child restraint precautions
Lexus strongly urges the use of child restraint systems for
children small enough to use them.
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 ºSeat beltsº on page 88 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. 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
if you are unrestrained.
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.

Never put a rear±facing child restraint system on the
front seat. In the event of an accident, the force of the
rapid inflation of the airbag can cause death or
serious injury if a rear±facing child restraint system
is put on the front seat.
Unless it is unavoidable, do not put a forward±facing
child restraint system on the front seat.
A forward±facing child restraint system should be
allowed to be put on the front passenger seat only
when it is unavoidable. Always move the seat as far
back as possible, because the force of the deploying
front passenger airbag could cause death or serious
injury to the child.
Make sure you have complied with all installation
instructions provided by the child restraint
manufacturer and that the system is properly
secured.
Do not allow the child to lean against the front door
or around the front door even if the child is seated in
a child restraint system. It is dangerous if the side
airbag and curtain shield airbag inflate, because the
impact could cause death or serious injury to the
child.Child restraint system
A child restraint system for a small child or baby must
itself be properly restrained on the seat with the lap
portion of the lap/shoulder belt. You must carefully
consult the manufacturer's instructions which
accompany the child restraint system.
To provide proper restraint, use a child restraint system
following the manufacturer's instructions about the
appropriate age and size of the child for the restraint system.
Install the child restraint system correctly following the
instructions provided by its manufacturer. General directions
are also provided under the following illustrations.
The child restraint system should be 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.

CAUTION
Never put a rear±facing child restraint system on the
front seat. In the event of an accident, the force of the
rapid inflation of the airbag can cause death or
serious injury if a rear±facing child restraint system
is put on the front seat.
Unless it is unavoidable, do not put a forward±facing
child restraint system on the front seat.
A forward±facing child restraint system should be
allowed to be put on the front passenger seat only
when it is unavoidable. Always move the seat as far
back as possible, because the force of the deploying
front passenger airbag could cause death or serious
injury to the child.
Do not allow the child to lean against the front door
or around the front door even if the child is seated in
a child restraint system. It is dangerous if the side
airbag and curtain shield airbag inflate, because the
impact could cause death or serious injury to the
child.
After installing the child restraint system, make sure
it is secured in place according to the manufacturer's
instructions. If it is not restrained securely, it may
cause death or serious injury to the child in the event
of a sudden stop or accident.
When not using the child restraint system, keep it secured with
the seat belt or place it in the trunk or somewhere other than
in the passenger compartment. This will prevent it from
injuring passengers in the event of a sudden stop or accident.
Your vehicle has anchor brackets for securing the top strap of
a child restraint system.
For instructions about how to use the anchor bracket, see
ªUsing a top strapº on page 126.
