possible:

Any of the SRS side airbags and curtain shield airbags have
been inflated.
 The portion of the doors (shaded in the illustration) were
involved in an accident that was not severe enough to cause
the SRS side airbags and curtain shield airbags to inflate.
 The surface of the seats with the side airbags (shaded in the
illustration) is scratched, cracked, or otherwise damaged.
 The portion of the front, center and rear pillar garnish, roof
interior containing the curtain shield airbags inside (shaded
in the illustration) is scratched, cracked, or otherwise

FRONT PASSENGER OCCUPANT CLASSIFICATION SYSTEM
Your vehicle is equipped with a front passenger occupant
classification system. This system detects the conditions
1. through 4. in the table on page 160 and based on these
conditions activates or deactivates the following
systems;
 Front passenger airbag
 Side airbag on the front passenger seat
 Front passenger’s seat belt pretensioner
The system monitors the weight and load on the front
passenger seat, and the seat belt buckle switch to
determine conditions 1. through 4.
In order for the system to detect the conditions correctly,
do not do any of the following:
 Apply a heavy load to the front passenger seat or equipment
(e.g. armrest).
 Attach a commercial seatback table, etc. to the front
passenger seatback.
 Put weight on the front pa ssenger seat by putting your
hands or feet on the seatback from the rear passenger seat.

The front passenger occupant classification indicator
light indicates the actuation of the front passenger airbag,
side airbag on the front passenger seat and front
passenger’s seat belt pretensioner.
The indicator light will indicate “OFF” when the ignition switch
is in the “ON” position with the condition 2 in the table shown
below.
If the front passenger occupant classification system
determines that a person of adult size sits in the front
passenger seat but the “OFF” indicator is illuminated, one of
the following is likely to have occurred:
 A rear passenger lifts the front passenger seat cushion with
their legs.
 Objects are placed under the front passenger seat.
 The front passenger seatback is in contact with the rear
seat. To ensure the system correctly detects an adult sitting in the
front passenger seat, make sure the above do not occur.
Make sure that the “ON” indicator is illuminated when an adult
is seated in the front passenger seat. If the “OFF” indicator is
illuminated, ask the passenger to sit up straight, well back in
the seat, and with the seat belt worn correctly. If the “OFF”
indicator still
remains illuminated, either ask the passenger to
move to the rear seat, or if that is not possible, move the front
passenger seat fully rearward.
The front passenger occupant classification indicator
light will indicate “ON” and “OFF” when the ignition key
is turned to the “ON” position. After about 4 seconds, it
will go off. After about 2 seconds, the front passenger
occupant classification system operates and judges
whether to indicate “ON” or “OFF”.

*1: The system judges a person of adult size as an adult. When a smaller adu\
lt sits in the front passenger seat, the system may
recognize him/her as a child depending on his/her physique and posture.
*2: When a larger child who has outgrown a child restraint system sits in the front\
passenger seat, the system may recognize him/heras an adult depending on his/her physique or posture.
*3: Never install a rear −facing child restraint system on the front passenger seat. A forward −facing child restraint system should only
be installed on the front passenger seat when it is unavoidable. (See “\
Child restraint” on page 162 as for installing the child restraint system.)
*4: When the front passenger does not wear a seat belt.

CAUTION
To avoid potential death or serious injury when the front
passenger occupant classification system does not
detect the conditions correct ly, observe the following:
Make sure the front passenger occupant
classification indicator light indicates “ON” when
using the seat belt extender for the front passenger
seat. If the indicator light indicates “OFF”,
disconnect the extender t ongue from the seat belt
buckle, then reconnect the seat belt. Reconnect the
seat belt extender after making sure the indicator
light indicates “ON”. If you use the seat belt extender
while the indicator light indicates “OFF”, the front
passenger airbag and side airbag on the front
passenger side may not ac tivate correctly, which
could cause death or serious injury in the event of
collision.
Do not recline the front passenger seatback so far
that it touches a rear seat. This may cause the “OFF”
indicator to be illuminated, which indicates that the
passenger’s airbags will not deploy in the event of a
severe accident. If the seat back touches the second
seat, return the seatback to a position where it does
not touches the second seat.
Keep the front passenger seatback as upright as
possible when the vehicle is moving. Reclining the
seatback excessively may lessen the effectiveness of
the seat belt system.
If an adult sits in the front passenger seat, the
occupant classification indicator light should
indicate “ON”. If the “OFF” indicator is illuminated,
ask the passenger to sit up straight, well back in the
seat, feet on the floor, and with the seat belt worn
correctly. If the “OFF” indicator still remains
illuminated, either ask the passenger to move to the
second seat, or if that is not possible, move the front
passenger seat fully rearward.
Wear the seat belt properly.
Make sure the front passenger’s seat belt tab has not
been left inserted into the buckle before someone sits
in the front passenger seat.
Do not apply a heavy load to the front passenger seat
or equipment (e.g. armrest).
Do not put weight on the front passenger seat by
putting your hands or feet on the front passenger
seatback from the second seat.
Do not let a second seat passenger lift the front
passenger seat with their feet or press on the
seatback with their legs.
Do not put objects under the front passenger seat.
 Do not modify or replace the upholstery of the front seat.
Child restraint systems inst alled on the second seat
should not contact the front seatbacks.

OCCUPANT RESTRAINT SYSTEMS

When it is unavoidable to install the forwardfacing
child restraint system on the front passenger seat,
install the child restraint system on the front
passenger seat in the proper order. (As for the
installation order, see “Ins tallation with 3point type
seat belt” on page 171.)
Do not remove the front seats.
Do not kick the front passe nger seat or subject it to
severe impact. Otherwise, the SRS warning light may
come on to indicate a malfunction of the detection
system. In this case, cont act your Toyota dealer
immediately.
The front passenger occupant classification indicator light may
indicate “ON” when a child sits in, or a forward −facing child
restraint system is installed on the front passenger seat. If the
“OFF” indicator is not illuminated in these circumstances, the
front passenger airbag and side airbag on the front passenger
side are in an active condition—the airbags will deploy if an
impact meets the deployment criteria. Refer to all the cautions
in this section, and “Child restraint” that follows.
CHILD RESTRAINT
Child restraint precautions
Lexus strongly urges the use of appropriate child
restraint systems for children.
The laws of all 50 states in the U.S.A. and Canada now require
the use of 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 “Seat belts” on page 121 for details.
CAUTION
 For effective protection in automobile accidents and
sudden stops, a child must be properly restrained,
using a seat belt or child restraint depending on age
and size of the child. 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.
 Lexus strongly urges use of a proper child restraint
system which 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.

OCCUPANT RESTRAINT SYSTEMS
176Install the child restraint system on the front passenger seat
only when it is unavoidable. Your vehicle is equipped with a
front passenger occupant classification system. In order to
activate
the occupant classification system correctly, install the
forward−facing child restraint system on the front passenger
seat in the following order:
1. Turn the ignition key to the “ON” position.
2. Move the front passenger seat to the rearward position.
3. Put the child restraint system on the front passenger seat
without putting your weight on the front passenger seat.
4. Insert the seat belt tab into the seat belt buckle.
5. Fully extend the shoulder belt to put it in the lock mode.
When the belt is then retrac ted even slightly, it cannot be
extended. To hold the seat securely, make sure the belt is in the
lock mode before letting the belt retract.
6. While pressing the convertible seat firmly against the seat
cushion and seatback, let the shoulder belt retract as far as it
will go to hold the convertible seat securely.
CAUTION
Push and pull the child r estraint system in different
directions to be sure it is secure. Follow all the
installation instructions pr ovided by its manufacturer.
7. Put a child on the child restraint system and secure the child,
complying with the instructions provided by the child restraint
system manufacturer. The occupant classification indicator light should indicate
“OFF”
when the ignition key is in the “ON” position and the child
is in the child restraint system after following these procedures.
The “OFF” indicator indicates the SRS front passenger airbag
will not deploy. If the indicator light indicates “ON”, remove the
child restraint system and reinstall it with the ignition key in the
“ACC” or “LOCK” position. If the indicator light still indicates
“ON” when the ignition key is turned to the “ON” position, then
the SRS front passenger airbag may deploy in an accident. Do
not drive the vehicle in this condition. Remove the child
restraint system and contact your Lexus dealer.
CAUTION
Never install a rearfacing child restraint system on
the front passenger seat. A forwardfacing child
restraint system should only be installed on the front
passenger seat when unavoidable. If you must install
the child restraint system on the front passenger
seat, put the seat in its mo st rearward position, and
install the forwardfacing child restraint system in
the proper order. Otherw ise, the front passenger
occupant classification system cannot detect the
presence of the child rest raint system and the front
passenger airbag could deploy.
