Do not allow anyone to get his/her head or hands out
of windows, since the curtain shield airbags could
inflate with considerable speed and force.
Otherwise, he/she may be killed or seriously injured.
Special care should be taken especially when you
have a small child in the vehicle. Do not attach a cupholder or any other device or
object on or around the door. When the side airbag
and curtain shield airbag inflate, the cupholder or any
other device or object will be thrown with great force,
or the side airbag and curtain shield 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.

OCCUPANT RESTRAINT SYSTEMS
165
Do not attach a microphone or any other device or
object around the area where the curtain shield
airbag activates such as on the windshield glass,
side door glass, front and rear pillars, roof side rail
and assist grips. When the curtain shield airbag
inflates, the microphone or other device or object will
be thrown away with great force or the curtain shield
airbag may not activate correctly, resulting in death
or serious injury.
 Do not hook a hanger , heavy or sharp pointed objects
on the coat hook. If the curtain shield airbag inflates,
those items will be thrown away with great force or
the curtain shield airbag may not activate correctly,
resulting in death or serious injury. When you hang
clothes, hang them on the coat hook directly.
 Do not use seat accessories which cover the parts
where the side airbags inflate. Such accessories may
prevent the side airbags from activating correctly,
causing death or serious injury.
 Do not modify or replace the seats or upholstery of
the seats with side airbags. Such changes may
prevent the side airbag system from activating
correctly, disable the system or cause the side
airbags to inflate accidentally, resulting in death or
serious injury.
 Do not disassemble or repair the front and rear pillars
and roof side rail containing the curtain shield
airbags. Such changes may disable the system or
cause the curtain shield airbags to inflate
accidentally, resulting in death or serious injury.
 Do not modify or change the suspension system.
Such changes may cause the curtain shield airbags
to inflate accidentally, which could result in death or
serious injury . Consult your Lexus dealer about any
repair and modification.
 Do not use tires or wheels other than the
manufacture’s recommended size. Such a use may
cause the curtain shield airbags and seat belt
pretensioners to inflate accidentally, which could
result in death or serious injury. For details, see
“Checking and replacing tires” on page 538.

OCCUPANT RESTRAINT SYSTEMS
166
Do not place luggage heavier than specified on the
roof luggage carrier. Such luggage may cause the
curtain shield airbags and seat belt pretensioners to
inflate accidentally, which could result in death or
serious injury. For details, see “Roof luggage
carrier” on page 107.
Failure to follow these instructions can result in death
or serious injury. Consult your Lexus dealer about any
repair and modification.
If you wish to modify your vehicle for a person with a
physical disability, consult your Lexus dealer. It may
dangerously interfere with the SRS side airbags and
curtain shield airbags operation.
NOTICE
Do not perform any of the following changes without
consulting your Lexus dealer. Such changes can
interfere with proper operation of the SRS side airbag
and curtain shield airbag system in some cases.
 Installation of electronic devices such as a mobile
twoway radio, cassette tape player or CD player
 Modification of the suspension system
 Modification of the structure of the passenger
compartment
 Repairs made on or near the console or front seat
The indicator comes on when the ignition key is turned to
the “ON” position. It goes off after about 6 seconds. This
means the SRS side airbags and curtain shield airbags are
operating properly.

sensor assemblies, curtain shield airbag sensor assemblies,
driver’s seat position sensor, driver’s seat belt buckle switch,

OCCUPANT RESTRAINT SYSTEMS
168In 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) was
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 airbag (shaded in the
illustration) is scratched, cracked, or otherwise damaged.
 The portion of the front pillars, rear pillars or roof side rail
garnishes (padding) 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 — 4 in the table on page 171, 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 in
determining conditions 1 — 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 passenger seat by putting your
hands or feet on the seat seatback from the rear passenger
seat.

169
The “AIRBAG OFF” indicator lights will be illuminated
when the ignition switch is in the “ON” position and a child
or child restraint system is in the front passenger seat (see
tablecondition 2). This indicates that in the event of a
severe frontal or passenger’s side impact, the front
passenger airbag and side airbag on the front passenger
seat are deactivated and will not deploy. If the front passenger occupant classification system
determines that a person of adult size sits in the front
passenger seat but the “AIRBAG OFF” indicator light is
illuminated, one of the following is likely to have occurred:

The rear passenger lifts the front passenger seat cushion
with their legs.
 Objects are placed under the front passenger seat.
 A front passenger seat seatback is in contact with a 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 the “AIRBAG ON” indicator light is illuminated when
an adult sits in the front passenger seat. If the “AIRBAG OFF”
indicator light is illuminated, ask the passenger to sit up
straight, well back in the seat, and with the seat belt worn
correctly. If the “AIRBAG OFF” indicator light 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.

OCCUPANT RESTRAINT SYSTEMS
170The “AIRBAG ON” and “AIRBAG OFF” indicator light will
be initially illuminated when the ignition switch is turned
to the “ON” position. It will remain for about four seconds
and then go off. After about two seconds, the front
passenger occupant classification system operates and
judges whether to turn the indicator light on or not.
The SRS warning light and “AIRBAG OFF” indicator light
will be illuminated if there is a malfunction in the front
passenger occupant classification system.

*1: The system judges a person of adult size as an adult. When a smaller ad\
ult 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/her as 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 system” on page 176 as for installing
the child restraint system.)
