Seat belt pretensioners
G16015
Both front seats and the two outboard rear seats are
equipped with seat belt pretensioners and are designed to
be activated in response to a severe frontal impact.
When the sensor detects a severe frontal impact, the seat belts
are quickly drawn back by the retractor so that the belts snugly
restrain the occupants.
The front passenger seat belt pretensioner will not activate if
there is no passenger sitting in the front passenger seat.
However, the front passenger seat belt pretensioner may
activate if luggage is put in the seat, or the seat belt is buckled
up regardless of the presence of the occupant in the seat.
The outboard rear seat belt pretensioners are activated even
with no passengers in the outboard rear seats.
The seat belt pretensioners and SRS airbags may not operate
together in all collisions.

CAUTION
The SRS side airbag and curtain shield airbag system
is designed only as a supplement to the primary
protection of the driver, front passenger and rear
outboard passenger seat belt systems. 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 151.
 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 airbag could cause death or serious injury
to the occupant.
 Improperly seated and/or restrained infants and
children can be killed or seriously injured by the
deploying airbags. An infant or child who is too small
to use a seat belt should be properly secured using
a child restraint system. Lexus strongly
recommends that all infants and children be placed
in the rear seats of the vehicle and properly
restrained. The rear seats are the safest for infants
and children. For instructions concerning the
installation of a child restraint system, see “Child
restraint” on page 182 .

Rear side airbag modules (airbag and inflator)
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.
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 serious injuries, it may also
cause minor burns or abrasions and swelling.
Front (and outboard rear) seats as well as the parts of the front
and rear pillars, and roof side rail may be hot for several
minutes, but the airbags themselves will 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.
G16137
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.

OCCUPANT RESTRAINT SYSTEMS
179
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 front (and outboard rear)
seats or upholstery of the seats with front (and rear)
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.
Failure to follow these instructions can result in death
or serious injury. Consult your Lexus dealer about any
repair and modification.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, front (or
outboard rear) seats .

Installation with child restraint lower
anchorages
G16065
Lower anchorages for the child restraint systems
complying with the FMVSS225 or CMVSS210.2
specifications are installed in the rear seat.
The anchorages are installed in the gap between the seat
cushion and seatback of both outboard rear seats.
Child restraint system comp lying with the FMVSS213 or
CMVSS213 specification can be fixed to these anchorages. In
this case, it is not necessary to fix the child restraint system
with a seat belt on the vehicle.

AIR CONDITIONING
270However, when the outside temperature is low, the indicator
light
comes on and the “A/C” switch turns on, but the air intake
control remains the same. When the interior is purified
sufficiently with fresh air after about 1 minute, this mode will be
turned off automatically and the indicator light will go out, but
the “A/C” switch remains on.
When the micro dust and pollen filter is activated, this mode will
be turned off by pushing any of the following buttons:
 Micro dust and pollen filter button
 “A/C” button
 Windshield air flow button
The indicator light will go out when the mode is turned off.
INFORMATION
 Use and push the windshield air flow button to
remove the fog on the windshield in rainy days.
 Fresh air is delivered even when the micro dust and
pollen filter button is turned off.
(d) 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 dashboard
vents and rear vents. (See (e) “Center vents, side vents and
rear vents”.)
 Only 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
control button be set to the OUTSIDE AIR mode to take in
the fresh air and the fan speed selector to any setting except
OFF.
