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 dealer before you scrap your vehicle.
Perchlorate Material
Special handling may apply, See www.dtsc.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
nGeneral 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 could result in death or serious injury.
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 attention to driving. Anything that distracts
the driver, such as adjusting controls, talking on a cellular phone or reading can
result in a collision with resulting death or serious injury to you, your occupants or
others.
nGeneral precaution regarding children’s safety
Never leave children unattended in the vehicle, 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 significant injury to the occupants. They
work together with the seat belts to help reduce the risk of death or serious
injury.
SRS front airbags
SRS driver airbag/front passenger airbag
Can help protect the head and chest of the driver and front passen-
ger from impact with interior components
SRS knee airbags
Can help provide driver and front passenger protection

SRS airbag system components
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 consists of the driver’s seat position sensor etc. The
front passenger’s airbag system consists of the front passenger occupant
classification sensor etc.

1-7. Safety information
The main SRS airbag system components are shown above. The SRS air-
bag system is controlled by the airbag 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 chemical reaction in the inflators quickly
fills the airbags with non-toxic gas to help restrain the motion of the occu-
pants.
nIf the SRS airbags deploy (inflate)
lBruising and slight abrasions may result from contact with a deploying (inflating)
SRS airbag.
lA loud noise and white powder will be emitted.
lParts of the airbag module (steering wheel hub, airbag cover and inflator) as
well as the seats, and parts of the front and rear pillars, and roof side rails, may
be hot for several minutes. The airbag itself may also be hot.
lThe windshield may crack.
lFor Safety Connect subscribers, if the SRS airbags deploy or in the event of a
severe rear-end collision, the system is designed to send an emergency call to
the response center, notifying them of the vehicle’s location (without needing to
push the “SOS” button) and an agent will attempt to speak with the occupants
to ascertain the level of emergency and assistance required. If the occupants
are unable to communicate, the agent automatically treats the call as an emer-
gency and helps to dispatch the necessary emergency services. (→P. 4 3 6 )

Before driving
nSRS airbag deployment conditions (SRS front airbags)
lThe SRS front airbags will deploy in the event of an impact that exceeds the
set threshold level (the level of force corresponding to an approximately 12 -
18 mph [20 - 30 km/h] frontal collision with a fixed wall 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.).
lIt is possible that in some collisions where the forward deceleration of the vehi-
cle is very close to the designed threshold level, the SRS front airbags and the
seat belt pretensioners may not activate together.
lThe SRS front passenger airbag will not activate if there is no passenger sitting
in the front passenger seat. However, the SRS front passenger airbag may
deploy if luggage is put in the seat, or the seat belt is fastened, even if the seat is
unoccupied. (→P. 7 5 )
nSRS airbag deployment conditions (SRS side airbags and curtain shield airbags)
The SRS side airbags and curtain shield airbags will deploy in the event of an impact
that exceeds the set threshold level (the level of force corresponding to the impact
force produced by an approximately 3300 lb. [1500 kg] vehicle colliding with the
vehicle cabin from a direction perpendicular to the vehicle orientation at an
approximate speed of 12 - 18 mph [20 - 30

km/h
]).

nConditions under which the SRS airbags may deploy (inflate), other than a colli-
sion (SRS front airbags)
The SRS front airbags may also deploy if a serious impact occurs to the underside of
your vehicle. Some examples are shown in the illustration.
The SRS curtain shield airbags may also deploy under the situations shown in the
illustration.
nTypes of collisions that may not deploy the SRS airbags (SRS front airbags)
The SRS front airbags are generally not designed to inflate if the vehicle is involved
in a side or rear collision, if it rolls over, or if it is involved in a low-speed frontal colli-
sion. But, whenever a collision of any type causes sufficient forward deceleration of
the vehicle, deployment of the SRS front airbags may occur.
lHitting a curb, edge of pavement or hard
surface
lFalling into or jumping over a deep hole
lLanding hard or vehicle falling
lThe angle of vehicle tip-up is marginal.
lThe vehicle skids and hits a curb stone.
lCollision from the side
lCollision from the rear
lVehicle rollover

nTypes of collisions that may not deploy the SRS airbags
(SRS side airbags and curtain shield airbags)
The SRS side airbag and curtain shield airbag system may not activate if the vehicle
is subjected to a collision from the side at certain angles, or a collision to the side of
the vehicle body other than the passenger compartment.
The SRS side airbags and curtain shield airbags are not generally designed to
inflate if the vehicle is involved in a frontal or rear collision, if it rolls over, or if it is
involved in a low-speed side collision.
lCollision from the side to the vehicle body
other than the passenger compartment
lCollision from the side at an angle
lCollision from the front
lCollision from the rear
lVehicle rollover

nWhen to contact your Lexus dealer
In the following cases, contact your Lexus dealer as soon as possible.
lAny of the SRS airbags has been inflated.
lThe front of the vehicle is damaged or
deformed, or was involved in an accident
that was not severe enough to cause the
SRS airbags to inflate.
lA portion of the doors is damaged or
deformed, or the vehicle was involved in an
accident that was not severe enough to
cause the SRS side airbags and curtain
shield airbags to inflate.
lThe pad section of the steering wheel,
dashboard near the front passenger airbag
or lower portion of the instrument panel is
scratched, cracked, or otherwise dam-
aged.
lThe surface of the seats with the side air-
bag is scratched, cracked, or otherwise
damaged.
lThe portion of the front pillars, rear pillars
or roof side rail garnishes (padding) con-
taining the curtain shield airbags inside is
scratched, cracked, or otherwise dam-
aged.

CAUTION
nSRS airbag precautions
Observe the following precautions regarding the SRS airbags.
Failure to do so may cause death or serious injury.
lThe driver and all passengers in the vehicle must wear their seat belts properly.
The SRS airbags are supplemental devices to be used with the seat belts.
lThe SRS driver airbag deploys with considerable force, and can cause death or
serious injury especially if the driver is very close to the airbag. The National
Highway Traffic Safety Administration (“NHTSA”) advises:
Since the risk zone for driver’s airbag is the first 2 - 3 in. (50 - 75 mm) of inflation,
placing yourself 10 in. (250 mm) from your driver airbag provides you with a
clear margin of safety. This distance is measured from the center of the steering
wheel to your breastbone. If you sit less than 10 in. (250 mm) away now, you can
change your driving position in several ways:
