The SRS airbag sensor assemblies consist of a safing
sensor and driver and front passenger airbag sensors.
In a severe frontal impact, the driver and front passenger
airbag sensors detect deceleration and the system
triggers the front airbag inflators and seat belt
pretensioners. In a severe side impact, the side airbag
sensor triggers the side airbag inflator. Then a chemical
reaction in the inflators momentarily fills the airbags with
non±toxic gas to help restrain the forward or lateral
motion of the occupants. Then the inflators fill the
airbags and the seat belts are quickly drawn back in by
the retractors to help restrain forward motion of the
occupants.When the SRS operates, it produces a fairly loud noise
and release some smoke and residue along with
non±toxic gas. This does not indicate a fire. This gas is
normally harmless, however, for those who have
delicate skin, it may cause minor skin irritation. 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, front seats) may be hot for several minutes,
but the airbags themselves will not be hot. The airbags
are designed to inflate only once.
A crash severe enough to inflate the driver and front
passenger airbags may break the windshield as the
vehicle buckles. In vehicles with a front passenger
airbag, the windshield may also be damaged by
absorbing some of the force of the inflating airbag.

Do not lean against the front door when the
vehicle is in use. The side airbag inflates with
considerable speed and force; you may be
killed or seriously injured.
Do not apply excessive weight to the outer side
of the front seats on vehicles with side airbags.
The child head should not be leaned against
the vicinity of the part where the side airbag
activates.

COMFORT ADJUSTMENT

Do not use accessories for the seats which
cover the parts where the side airbags should
inflate. Such accessories may prevent the side
airbags from activating correctly, causing
death or serious injury.
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 seats, airbag sensor
assembly or seat belt assemblies. Doing any of
these may cause sudden SRS operation or
disable the system, which could result in death
or serious injury.
Do not modify or replace the seats or surface of
the front seats with side airbags. Such
changes may disable the system or cause the
side airbags to inflate, resulting in death or
serious injury. Consult your Lexus dealer.
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 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 and side
structure of the passenger compartment.
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, front
end structure, console, steering column,
steering wheel, dashboard near the front
passenger airbag, front seats or seat belt
assembly.

soon as possible:
Any of the SRS airbags have been inflated.
If either front seat belt does not retract or cannot be
pulled out due to a malfunction or activation of the
pretensioner.The front seat belt retractor assembly or surrounding
area has been damaged.
The front part of the vehicle and portion of the doors
(shaded in the illustration) were involved in an
accident that did not cause the SRS to work.
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.
