 Do not attach a cupholder or any other device or
object on or around the door. When the side airbag
inflates, the cupholder or any other device or object
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 objects in their arms or on their
knees.

In the following cases, contact your Lexus dealer as soon as
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
damaged.
NOTICE
Do not disconnect the battery cables before contacting
your Lexus dealer.
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.

OCCUPANT RESTRAINT SYSTEMS
158
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”.

OCCUPANT RESTRAINT SYSTEMS
161
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
162
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
163
Never install a rearfacing child restraint system on
the front passenger seat even if the front passenger
occupant classification indicator light indicates
“OFF”. In the event of an accident, the force of the
rapid inflation of the front passenger airbag can
cause death or serious injury to the child if the
rearfacing child restraint system is installed on the
front passenger seat.
 A forwardfacing child restraint system should be
allowed to be installed on the front passenger seat
only when it is unavoidable. Always move the seat
as far back as possible even if the front passenger
occupant classification indicator light indicates
“OFF”, because the front passenger airbag could
inflate with considerable speed and force. Otherwise,
the child may be killed or seriously injured. 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 or 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.
 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.
 Make sure you have complied with all installation
instructions provided by the child restraint
manufacturer and that the system is properly
secured. If it is not secured properly, it may cause
death or serious injury to the child in the event of a
stop or accident.

OCCUPANT RESTRAINT SYSTEMS

Child restraint system
A child restraint system for a small child or baby must
itself be properly restrained on the seat with the lap
portion of the lap/shoulder belt. You must carefully
consult the manufacturer’s instructions which
accompany the child restraint system.
To provide proper restraint, use a child restraint system
following the manufacturer’s instructions about the
appropriate age and size of the child for the child restraint
system.
Install the child restraint system correctly following the
instructions provided by its manufacturer. General directions
are also provided under the following illustrations.
The child restraint system should be 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.
When not using the child restraint system, keep it secured with
the seat belt or place it somewhere other than the passenger
compartment. This will prevent it from injuring passengers in
the event of a sudden stop or accident.
Types of child restraint system
Child restraint systems are classified into the following 3 types
depending on the child’s age and size.
(A) Infant seat
(B) Convertible seat
(C) Booster seat
Install the child restraint syst em following the instructions
provided by its manufacturer.
Your vehicle has anchor brackets for securing the top strap of
a child restraint system.
For instructions about how to use the anchor bracket, see
“Using a top strap” on page 184.
The child restraint lower anchorages approved for your vehicle
may also be used. See “Installation with child restraint lower
anchorages” on page 186.

CAUTION
Do not install a rearfacing child restraint system on
the third seat if it interferes with the lock mechanism
of the second seats. Otherwise, the child or second
seat occupant(s) may be killed or seriously injured in
case of sudden braking or a collision.
 Child restraint systems installed on the third seat
should not contact the second seat backs.

1. Run the center lap belt through or around the infant seat
following the instructions provided by its manufacturer and
insert the tab into the buckle taking care not to twist the lap belt.
CAUTION
After inserting the tab, make sure the tab and buckle
are locked and that the lap belt is not twisted.
 Do not insert coins, clips, etc. in the buckle as this
may prevent you from properly latching the tab and
buckle.
 If the seat belt does not function normally, it cannot
protect your child from death or serious injury.
Contact your Lexus dealer immediately. Do not
install the child restraint system on the seat until the
seat belt is fixed.
