10Airbag 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 sensor.
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.
At this time a chemical reaction in the inflators quickly fills the
airbags with non −toxic gas to help restrain the lateral motion
of the occupants. In a vehicle rollover, the airbag sensor assembly triggers the
curtain shield airbag inflator.
At this time, a chemical reaction
in the inflators quickly fills the airbags with non −toxic gas to
help restrain the lateral motion of the occupants.
When the airbags inflate, they produce a fairly 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 se rious 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.
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.

OCCUPANT RESTRAINT SYSTEMS

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
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.

CAUTION
When using the lower anchorages for the child
restraint system, be sure that there are no irregular
objects around the anchorages or that the seat belt is
not caught.
 Push and pull the child restraint system in different
directions to be sure it is secure. Follow all the
installation instructions provided by its
manufacturer.
 Do not install a child restraint system on the second
seat if it interferes with the lock mechanism of the
front seats. This can cause death or serious injury to
the child and front passenger in case of sudden
braking or a collision.
 When using the left side lower anchorages for the
child restraint system, do not sit in the center seat.
The performance of the center seat belt cannot be
brought out sufficiently because the belt may be
highpositioned or the seat belt may be loosefitting,
posing the risk of serious injury in the case of
collision.

AIR CONDITIONING
221
This button allows the air intake to select the OUTSIDE AIR
mode automatically. This is to clean up the front view more
quickly. If you want to return the setting to the
RECIRCULATED
AIR mode, push the air intake control button
once again.
Push the “A/C” button for dehumidified heating or cooling. This
setting clears the front view more quickly.
CAUTION
Do not use the windshield air flow button during cooled
air operation in extremely humid weather. The
difference between the temperature of the outside air
and that of the windshield could cause the outer surface
of the windshield to fog up blocking your vision.
(c) Operating tips
 To help cool down the interior after parking in the hot sun,
drive for the first few minutes with the windows open. After
the excess heat has blown away, close the windows.
 Make sure the air inlet grilles in front of the windshield are
not blocked by leaves or other obstructions.
 If air flow control is not satisfactory, check the side vents and
rear vents. (See “(d) Center vents and side vents”.)
 On humid days, do not blow cold air on the windshield. The
windshield could fog up because of the difference in air
temperature on the inside and outside of the windshield.
 Keep the area under the front seats clear to allow air to
circulate throughout the vehicle.
 On cold days, set the fan speed to high for a minute to help
clear the intake ducts of snow or moisture. This can reduce
the amount of fogging on the windows.
 When driving on dusty roads, close all windows. If dust
thrown up by the vehicle is still drawn into the vehicle after
closing the windows, it is recommended that the air intake
be set to the OUTSIDE AIR mode and the fan speed to any
setting except “OFF”.

AUDIO
257
To clean a CDs: Wipe it with a soft, lint−free cloth that has been
dampened with water. Wipe in a straight line from the center
to the edge of the CD (not in a circle). Do not use a
conventional record cleaner or anti −static device.
REAR SEAT AUDIO SYSTEM
The rear seat audio system is designed for the rear seat
passengers to enjoy the audio sound separately between
the front seats and the rear seats.
The rear seat audio system can be turned on with the rear
audio system remote control even if the front audio system is
off. When the front audio is turned off, the rear audio system
will be turned off simultaneously.
The rear passengers can enjoy all the modes (AM and FM
radio, cassette tape player and CD player with changer) with
the rear seat audio system when a cassette tape and a CD are
loaded in the front audio system.
When the same mode is selected on the front and rear audio
systems at the same time, the system can be operated on the
front audio system.
If the radio mode is selected on the front and rear audio
systems at the same time, AM and FM modes cannot be
changed on the rear seat audio system.
