SUPPLEMENTAL RESTRAINT SYSTEM(SRS)
The Supplemental Restraint System (SRS) consists of driver and front
passenger airbags, side airbags and seat belt pretensioners. The
combination of these 3 systems is designed to provide further protection
for the driver and front passenger when added to the primary pr otection
provided by the seat belts.
16E124

Driver and front passenger airbags, and seat belt pretensioners
Driver and front passenger airbags:
In response to a severe frontal impact, the driver and front passenger
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 heads or chests from directly hitting the steering wheel
or dashboard. Seat belt pretensioners:
In response to a severe frontal impact, the seat belts are quickly drawn
back in by the retractors so that the belts snugly restrain the driver and
front passenger.
The front passenger airbag is activated even with no passenger in the front\
seat.
The seat belt pretensioners are activated together with the driver and fron\
t
passenger airbags, even with no passenger in the front seat.
Be sure to wear your seat belt.
CAUTION
The driver or front passenger too close to the steering wheel
or dashboard during airbag deployment can be killed or
seriously injured. Lexus strongly recommends that:

The driver sit as far back as possible from the steering
wheel while still maintaining control of the vehicle.
 The front passenger sit as far back as possible from the
dashboard.
 All vehicle occupants be properly restrained using the
available seat belts.

Vehicle roll±over
The side airbags are not designed to inflate if the vehicle is rolled over.
If the impact on the body of the passenger compartment is not strong as
illustrated above, the relevant side airbag may not inflate.

6SRS warning light
7Driver and front passenger airbag sensor assembly
The SRS airbag sensor assemblies consist of a safing sensor and driver and
front passenger airbag sensor.
In a severe frontal impact, the driver and front passenger airbag sensor d\
etects
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 along with non±toxic gas. This 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 happen in a fraction of a second, so the airbags
must inflate with considerable force. While the system is designed to reduc\
e

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 passeng\
er
airbag, the windshield may also be damaged by absorbing some of the force
of the inflating airbag.
CAUTION
 The SRS is designed only as a supplement to the primary
protection of the driver side and front passenger side seat
belt systems. The front seat occupants can be killed or
seriously injured by an inflating airbag if they do not wear
the available seat belts. During sudden braking just before
a collision, an unrestrained driver or front passenger can
move forward into direct contact with or close proximity to
the airbag which may then deploy during the collision. To
obtain maximum protection in an accident, the driver and
all passengers in the vehicle must wear their seat belts.
Wearing a seat belt during an accident reduces the chances
of death or serious injuries or being thrown out of the
vehicle. For instructions and precautions concerning the
seat belt system, see ºSeat beltsº on page 64.
 Improperly seated and/or restrained infants and children
can be killed or seriously injured by a deploying airbag. An
infant or child who is too small to use a seat belt should be
properly secured using a child restraint system. Lexus
strongly recommends that all infants and children be
placed in the rear seat of the vehicle and properly
restrained. The rear seat is the safest for infants and
children. For instructions concerning the installation of a
child restraint system, see ºChild restraintº on page 80 .

COMFORT ADJUSTMENT77
16E029
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 r estraint
system in the rear seat. For instructions concerning the installation
of a child restraint system, see ºChild restraintº on page 80.
16E030
 Do not put objects or your pets on or in front of the dashboard or
steering wheel pad that houses the driver and front passenger
airbag system. They might restrict inflation or cause death or
serious injury as they are projected rearward by the force of the
deploying airbags. Likewise, the driver and front passenger should
not hold things in their arms or on their knees.

COMFORT ADJUSTMENT

16E127
Do not attach a cup holder or any other device on or around the door.
When the side airbag inflates, the cup holder or any other device will
be thrown with great force, or the side airbag may not activate
correctly, resulting in death or serious injury. Likewise, the driver
and front passenger should not hold things in their arms or on their
knees.
 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 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.

CHILD RESTRAINT
Child restraint precautions
Lexus strongly urges the use of child restraint systems for children small
enough to use them.
The laws of all fifty states in the U.S.A. and Canada now require the use o\
f
a child restraint system.
Your vehicle conforms to SAE J1819.
If a child is too large for a child restraint system, the child should sit in the rear
seat and must be restrained using the vehicle's seat belt. See ºSeat beltsº on
page 64 for details.
CAUTION
For effective protection in automobile accidents and
sudden stops, children must be properly restrained using a
seat belt or child restraint depending on age and size.
Holding a child in your arms is not a substitute for a child
restraint system. In an accident, the child can be crushed
against the windshield, or between you and the vehicle's
interior if you are unrestrained.
 Lexus strongly urges use of a proper child restraint which
conforms to the size of the child and is put on the rear seat.
According to accident statistics, the child is safer when
properly restrained in the rear seat than in the front seat.
