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 sit on the edge of the seat or lean over the
dashboard when the vehicle is in use. The
airbags inflate with considerable speed and
force; you may be killed or seriously injured. Sit
up straight and well back in the seat, and always
use your seat belt.Do not allow a child to stand up, or to kneel on the
front passenger seat. The airbag inflates with
considerable speed and force; 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 ªChild restraintº on page 76.

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.
