1-7. Safety information

Before driving
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.
■SRS warning light
This warning light system monitors the airb ag sensor assembly, front airbag sensors,
side and curtain shield airbag sensor assemblies, curtain shield airbag sensor
assemblies, driver's seat position sensor, driver's seat belt buckle switch, seat belt
pretensioner assemblies, inflators, inte rconnecting wiring and power sources.
(  P. 3 6 1 )
■If the SRS airbags deploy (inflate)
●Bruising and slight abrasions 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 front seats, and parts of the front pillar, rear pillar and roof side rail,
may be hot for several minutes. The airbag itself may also be hot.
●The front 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 airbag will not activate if there is no passenger sitting
in the front passenger seat. However, the front passenger airbag may deploy if
luggage is put in the seat, or the seat belt is fastened, even if the seat is unoccu-
pied. ( P. 9 0 )

1-7. Safety information
■When to contact your Lexus dealer
In the following cases, contact your Lexus dealer as soon as possible. Do not dis-
connect the battery cables before contacting your Lexus dealer.
●Any of the SRS airbags have been inflated.
●The 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.
●A 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.
●The pad section of the steering wheel, front
passenger airbag cover or lower portion of
the instrument panel is scratched, cracked,
or otherwise damaged.
●The surface of the seats with the side air-
bag is scratched, cracked, or otherwise
damaged.
●The 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
■SRS airbag precautions
●Do not sit on the edge of the seat or lean
against the dashboard.
●Do not allow a child to stand in front of the
SRS front passenger airbag unit or sit on
the knees of a front passenger.
●Do not drive the vehicle while the driver or
passenger have items resting on their
knees.
●Do not lean against the door, the roof side
rail or the front, side and rear pillars.
●Do not allow anyone to kneel on the pas-
senger seat toward the door or put their
head or hands outside the vehicle.

CAUTION
■SRS airbag precautions
●If the vinyl cover is put on the area where the SRS knee airbag will deploys, be
sure to remove it.
●Do not use seat accessories which cover the parts where the SRS side airbags
inflate as they may interfere with inflation of the airbags.
●Do not strike or apply significant levels of force to the area of the SRS airbag
components shown on P. 80.
Doing so can cause the SRS airbags to malfunction.
●Do not touch any of the component parts immediately after the SRS airbags have
deployed (inflated) as they may be hot.
●If breathing becomes difficult after the SRS airbag has deployed, open a door or
window to allow fresh air in, or leave the vehicle if it is safe to do so. Wash off any
residue as soon as possible to prevent skin irritation.
●If the areas where the SRS airbags are stored, such as the steering wheel pad and
front pillar garnish, are damaged or cracked, have them replaced by your Lexus
dealer.
●Do not attach anything to or lean anything
against areas such as the dashboard, steer-
ing wheel pad or lower portion of the
instrument panel.
These items can become projectiles when
SRS driver, front passenger and knee air-
bags deploy.
●Do not attach anything to areas such as the
door, windshield glass, side door glass,
front and rear pillars, roof side rail or assist
grip.
●Do not hang coat hangers or other hard
objects on the coat hooks. All of these
items could become projectiles and seri-
ously injure or kill you, should the SRS cur-
tain shield airbag deploy.

■Modification and disposal of SRS airbag system components
Do not dispose of your vehicle or perform any of the following modifications with-
out consulting your Lexus dealer.
The SRS airbag may malfunct ion or deploy (inflate) accidentally, causing death or
serious injury.
●Installation, removal, disassembly and repair of the SRS airbags
●Repairs, modifications, removal or replace ment of the steering wheel, instrument
panel, dashboard, seats or seat upholstery, front, side and rear pillars or roof side
rails

CAUTION
■Child restraint precautions
●Lexus strongly urges the use of a proper child restraint system that conforms to
the size of the child, installed 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 a rear-facing child restrain t system on the front passenger seat. In
the event of an accident, the force of the rapid inflation of the front passenger air-
bag can cause death or serious injury to the child if the rear-facing child restraint
system is installed on the front passenger seat.
●A forward-facing child restraint system shou ld allowed to be installed on the front
passenger seat only when it is unavoidable. Always move the seat as far back as
possible, because the front passenger airbag could inflate with considerable
speed and force. Otherwise, the child may be killed or seriously injured.
●Do not use the seat belt extender when installing a child restraint system on the
front or rear passenger seat. If installing a child restraint system with the seat belt
extender connected to the seat belt, the seat belt will not securely hold the child
restraint system, which could cause death or serious injury to the child or other
passengers in the event of collision.
●Do not allow the child to lean his/her head or any part of his/her body against the
door or the area of the seat, front pillar, rear pillar or roof side rail from which the
side airbags or curtain shield airbags deploy even if the child is seated in the child
restraint system. It is dangerous if the side airbags and curtain shield airbags
inflate, and the impact could cause death or serious injury to the child.
●Make sure you have complied with all inst allation instructions provided by the
child restraint manufacturer and that the sy stem is properly secured. If it is not
secured properly, it may cause death or seri ous injury to the child in the event of a
sudden stop or accident.
■When the child restraint system is not in use
●Keep the child restraint system properly secu red on the seat even if it is not in use.
Do not store the restraint unsecured in the passenger compartment.
●If it is necessary to detach the child restraint system, remove it from the vehicle or
store it securely in the trunk. This will prevent it from injuring passengers in the
event of a sudden stop or accident.
