CAUTION
To avoid serious personal injury, you must do the
following.
While the vehicle is moving, always keep the heads,
hands and other parts of the bodies of all occupants
away from the roof opening. Otherwise, they could
be seriously injured if the vehicle stops suddenly or
if the vehicle is involved in an accident.
 Before you close the moon roof, always make sure
there is nobody around the moon roof. You must also
make sure nobody places his or her head, hands and
other parts of the body in the roof opening. If
someone’s neck, head or hands get caught in the
closing roof, it could result in death or serious injury.
When anyone closes the moon roof, first make sure
it is safe to do so.
 Be sure to remove the ignition key when you leave
your vehicle.
 Never leave anyone (particularly a small child) alone
in your vehicle, especially with the ignition key still
inserted. Otherwise, he/she could use the moon roof
switches and get trapped in a moon roof. Unattended
person (particularly a small child) can be involved in
a serious accident.
 Never sit on top of the vehicle around the roof
opening.
 Never try jamming any part of your body to activate
the jam protection function intentionally, as it could
result in a serious injury.
 The jam protection function may not work if
something gets caught just before the moon roof
fully closed.

CAUTION
Do not modify, remove, strike or open the seat belt
pretensioner assemblies, airbag sensor or
surrounding area or wiring. Failure to follow these
instructions may prevent the seat belt pretensioners
from activating correctly, cause sudden operation of
the system or disable the system, which could result
in death or serious injury.
 Do not use tires or wheels other than the
manufacturer’s recommended size. Such a use may
cause the curtain shield airbags and seat belt
pretensioners to inflate accidentally, resulting in
death or serious injury. For details, see “Checking
and replacing tires” on page 438.
 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, resulting in death or serious
injury. For details, see “Roof luggage carrier” on
page 88.
 Do not modify or change the suspension system.
Such changes may cause the curtain shield airbags
to inflate accidentally, resulting in death or serious
injury.
Failure to follow these instructions can result in death
or serious injury. Consult your Lexus dealer before
performing any repair and modification.

The SRS side airbag on the passenger seat will not activate if
there is no passenger sitting in the front passenger seat.
However, the side airbag on the passenger seat may deploy
if luggage is put in the seat, or the seat belt is buckled up
regardless of
the presence of the occupant in the seat. (As for
the front passenger occupant classification system, see “Front
passenger occupant classification system” on page 157.)
Roll sensing function:
In response to a vehicle rollover, the curtain shield airbags on
both sides inflate. The curtain shield airbags work together
with the seat belts to help to reduce injuries mainly to the
driver’s head, front passenger’s head and second seat
passengers’ heads and can help the driver, front passenger
and second seat passengers to retain inside the vehicle.
The SRS curtain shield airbag on the passenger side is
activated even with no passenger in the front seat or second
seat.
The SRS curtain shield airbags may activate even when the
side airbags are not activated.
Always wear your seat belt properly.
CAUTION
 The SRS side airbag and curtain shield airbag system
is designed only as a supplement to the primary
protection of the driver, front and second outboard
seat passenger seat belt systems. The front and
second seat occupants can be killed or seriously
injured by the inflating airbags if they do not wear the
available seat belts properly . During sudden braking
just before a collision, an unrestrained driver, front
passenger or second seat passenger can move
forward or sideways into direct contact with or close
proximity to the airbag which may then deploy during
the collision. To ensure maximum protection in an
accident, the driver and all passengers in the vehicle
must wear their seat belts properly. Wearing a seat
belt properly during an accident reduces the chances
of death or serious injury or being thrown out of the
vehicle. For instructions and precautions
concerning the seat belt system, see “Seat belts” on
page 121.
 Do not allow anyone 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 SRS side airbag and curtain shield airbag deploy
even if he/she is a child seated in the child restraint
system. It is dangerous if the SRS side airbag and
curtain shield airbag inflate, and the impact of the
deploying airbags could cause death or serious
injury to the occupant.

9Airbag sensor assembly
The SRS side airbag and curtain shield airbag system consists
mainly of the above components, and their locations are
shown in the illustration.
The SRS side airbag and curtain shield airbag system is
controlled by the airbag sensor assembly. The airbag sensor
assembly consists of a safing sensor and airbag sensors. In a severe side impact, the side and curtain shield airbag
sensor and/or the curtain shield airbag sensor trigger(s) the
side airbag inflators and/or the curtain shield airbag inflators.
In a vehicle rollover, the airbag sensor assembly triggers the
curtain shield airbag inflator. At this time a chemical reaction
in the inflators very quickly fills the airbags with non
−toxic gas
to help restrain the forward or lateral motion of the front and
second seat occupants.
When the airbags inflate, they produce a loud noise and
release some smoke and residue along with non −toxic gas.
This does not indicate a fire. This smoke may remain inside
the vehicle for some time, and may cause some minor irritation
to the eyes, skin or breathing. Be sure to wash off any residue
as soon as possible to prevent any potential skin irritation with
soap and water. If you can safely exit from the vehicle, you
should do so immediately.
Deployment of the airbags happens in a fraction of a second,
so the airbags must inflate with considerable force. While the
system is designed to reduce serious injuries, it may also
cause minor burns or abrasions and swelling.
Front seats as well as parts of the front and rear pillars, and roof
side rail may be hot for several minutes, but the airbags
themselves will not be hot. The airbags are designed to inflate
only once.

CAUTION
SRS side airbags and curtain shield airbags inflate with
considerable force. To reduce the possibility of death
or serious injury when they inflate, the driver, front
passenger and rear outboard passengers must:
Wear their seat belts properly.
 Remain properly seated with their backs upright and
against the seats at all times.
16x520a
Do not allow anyone to lean against the door when
the vehicle is in use, since the side airbag and curtain
shield airbag 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.
 Sit up straight and well back in the seat, distributing
your weight evenly in the seat. Do not apply
excessive weight to the outer side of the seats with a
side airbag,and to the front pillar, rear pillar, and roof
side rail with a curtain shield airbag.
 Improper sitting and wearing of the seat belts may
not retain you inside the vehicle.

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, center and roof side garnish,
roof interior or 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 hurled away with great force or the
curtain shield airbag may not activate correctly,
which could result 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. Su ch 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.
 Do not use tires or wheels other than the

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.

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.
