SRS AIRBAGS
The SRS (Supplemental Restraint System) airbags are
designed to provide further protection to the driver and
front passenger when added to the primary protection
provided by the seat belts.
In response to a severe frontal impact, the SRS airbags
work together with the seat belts to help preventing or
reduce injury by inflating, in order to decrease the
likelihood of the driver's or front passenger's head or
chest directly hitting the steering wheel or dashboard.
The passenger airbag is activated even with no passenger
in the front seat.
This indicator comes on when the ignition key is turned
to the ªACCº or ªONº position. It goes off after about 6
seconds. This means the SRS airbags are operating
properly.
The SRS airbag warning light system monitors the front
airbag sensors, center airbag sensor assembly, inflators,
warning light, interconnecting wiring and power sources.

The airbag sensor assembly consists of a safing sensor and
center airbag sensor.
In a severe frontal impact, sensors detect deceleration and
the system triggers the airbag inflators. Then a chemical
reaction in the inflators momentarily fills the airbags with
non±toxic nitrogen gas to help restrain the forward motion of
the occupants.
When the airbags inflate, they produce a fairly loud noise and
release some smoke along with nitrogen gas. This is not
harmful and does not indicate a fire. Be sure to wash off any
residue as soon as possible to prevent minor skin irritation.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 swellings.
Parts of the airbag module (steering wheel hub, dashboard)
may be hot for several minutes, but the airbags themselves
will not be hot. The airbags are designed to operate only
once.
A crash severe enough to inflate the airbags may break the
windshield as the vehicle buckles. In vehicles with a
passenger airbag the windshield may also 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 seat
belt systems of the driver and front passenger.
The front seat occupants are particularly
susceptible to injury if they do not wear their seat
belts; when sudden braking or a collision occurs,
they may be thrown forward. To obtain maximum
protection in an accident, the driver and all
passengers in the vehicle should always wear
their seat belts when driving because death or
serious injuries can result to unrestrained
occupants. For instructions and precautions
concerning the seat belt system, see ªSeat beltsº
on page 63.

Do not put objects on or in front of the dashboard
or steering wheel pad that houses the airbag
system. They might restrict inflation or cause
serious injury as they are projected rearward by
the force of the deploying airbags.
Do not modify or remove any wiring, such as the
steering wheel column cover, front passenger
airbag cover, front passenger airbag, or airbag
sensor assembly. Doing any of these may cause
sudden SRS airbag inflation or disable the
system, which could result in death or serious
injury.
Failure to follow these instructions can result in
death or serious injuries.
NOTICE
Do not perform any of the following changes
without consulting your Lexus dealer. Such
changes can interfere with proper operation of the
SRS airbag system in some cases.
Installation of electronic items 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.), snow plow, winches or any other
equipment to the front end.
Repairs made on or near the front fenders,
console, steering column, steering wheel or
dashboard near the front passenger airbag.

The pad section of the steering wheel or front passenger
airbag cover (shaded in the illustration) is scratched,
cracked, or otherwise damaged.
NOTICE
Do not disconnect the battery cables before
contacting your Lexus dealer.
CHILD RESTRAINT
Child restraint precautions
Lexus strongly urges the use of child restraint system
for children small enough to use it.
The laws of all fifty 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 ªSeat beltsº on page 63 for details.
CAUTION!
For effective protection in automobile accidents
and sudden stops, children must be properly
restrained using a seat belt or child restraint
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 conforms to the size of the child 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 install of 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 installed on the front seat.
Unless it is unavoidable, do not install a
forward±facing child restraint system on the front
seat.
