Scrapping of your Lexus
The SRS airbag and seat belt pretensioner devices in your Lexus contain explosive
chemicals. If the vehicle is scrapped with the airbags and seat belt pretensioners left
as they are, this may cause an accident such as fire. Be sure to have the systems of
the SRS airbag and seat belt pretensioner removed and disposed of by a qualified
service shop or by your Lexus deal er before you scrap your vehicle.
Perchlorate Material
Special handling may apply, See www.d tsc.ca.gov/hazardouswaste/perchlorate.
Your vehicle has components that may contain perchlorate. These components may
include airbag, seat belt pretensioners, and wireless remote control batteries.
CAUTION
■General precautions while driving
Driving under the influence: Never drive your vehicle when under the influence of
alcohol or drugs that have impaired your ability to operate your vehicle. Alcohol
and certain drugs delay reaction time, impair judgment and reduce coordination,
which could lead to an accident that will hurt or kill you, your occupants or others.
Defensive driving: Always drive defensively. Anticipate mistakes that other drivers
or pedestrians might make and be ready to avoid accidents.
Driver distraction: Always give your full at tention to driving. Anything that distracts
the driver, such as adjusting controls, ta lking on a cellular phone or reading can
result in a collision with resulting death or serious injury to you, your occupants or
others.
■General precautions regarding children’s safety
Never leave children unattended in the vehi cle, and never allow children to have or
use the key.
Children may be able to start the vehicle or shift the vehicle into neutral. There is
also a danger that children may injure themselves by playing with the cigarette
lighter, the windows, the moon roof, or other features of the vehicle. In addition, heat
build-up or extremely cold temperatures inside the vehicle can be fatal to children.

SRS airbags
The SRS airbags inflate when the vehicle is subjected to certain types of
severe impacts that may cause signific ant injury to the occupants. They
work together with the seat belts to he lp reduce the risk of death or serious
injury.
Front airbags
Driver airbag/front passenger airbag 
Can help protect the head and ches t of the driver and front passen-
ger from impact with interior components.
Knee airbag 
Can help provide driver and front passenger protection.
Side and curtain shield airbags
Front side airbag/rear side airbag (rear side airbags are optional)
Can help protect the torso of th e front occupants and rear out-
board occupants.

May 13, 2008 5:14 pm
Your vehicle is equipped with “ADVANCED AIRBAGS” designed based
on US motor vehicle safety standards (FMVSS208). The airbag system
controls airbag deployment power for the driver and front passenger. The
driver airbag system consist s of the driver’s seat position sensor etc. The
front passenger’s airbag system consist s of the front passenger occupant
classification sensor etc.
The main SRS airbag system componen ts are shown above. The SRS air-
bag system is controlled by the airb ag sensor assembly. The airbag sen-
sor assembly consists of a safing sensor and an airbag sensor.
In certain types of severe frontal or side impacts, the SRS airbag system
triggers the airbag inflators. A chemica l reaction in the inflators quickly
fills the airbags with non-toxic gas to he lp restrain the motion of the occu-
pants.
■If the SRS airbags deploy (inflate)
●Bruising and slight abrasion s may result from contact with a deploying (inflating)
SRS airbag.
●A loud noise and white powder will be emitted.
●Parts of the airbag module (steering wheel hub, airbag cover and inflator) as
well as the seats, and parts of the front pillar and roof side rail, may be hot for
several minutes. The airbag itself may also be hot.
●The windshield may crack.

■Operating conditions (front airbags)
●The SRS front airbags will deploy if the severity of the frontal impact is above the
designed threshold level, comparable to an approximate 15 mph (25 km/h) col-
lision when the vehicle impacts straight into a fixed barrier that does not move
or deform.
However, this threshold velocity will be considerably higher if the vehicle strikes
an object, such as a parked vehicle or sign pole, which can move or deform on
impact, or if the vehicle is involved in an underride collision (e.g. a collision in
which the front of the vehicle “underrides”, or goes under, the bed of a truck, etc.).
●It is possible that in some collisions where the forward deceleration of the vehi-
cle is very close to the designed thresh old level, the SRS front airbags and the
seat belt pretensioners ma y not activate together.
●The SRS front passenger airbags will not activate, if there is no passenger sitting
in the front passenger seat. However, th e front passenger airbag may deploy, if
the heavy luggage is put in the seat , even if the seat is unoccupied.
■Operating conditions (side and curtain shield airbags)
●The SRS side airbags and curtain shield ai rbags are designed to inflate when the
passenger compartment is subjected to a severe impact from the side.
●The SRS front side airbag on the passenger seat will not activate if there is no
passenger sitting in the front passenger seat. However, the front side airbag on
the passenger seat may deploy if the heavy luggage is put in the seat, even if the
seat is unoccupied. ( P. 9 2 )
