The seat belt pretensioner system consists mainly of the above
components, and their locations are shown in the illustration.
The seat belt pretensioners are controlled by the airbag sensor
assembly. The airbag sensor assembly consists of a safing
sensor and airbag sensor.
When the seat belt pretensioners are activated, an operating
noise may be heard and a small amount of non− toxic gas may
be released. This does not indicate that a fire is occurring. This
gas is normally harmless.
Once the seat belt pretensioners have been activated, the seat
belt retractors remain locked.

SRS DRIVER AIRBAG AND FRONTPASSENGER AIRBAG
The SRS (Supplemental Restraint System) front airbags
are designed to provide further protection for the driver
and front passenger in addition to the primary safety
protection provided by the seat belts.
Your vehicle is equipped with “ADVANCED AIRBAGS”
designed based on US motor vehicle safety standards
(FMVSS208). The airbag system controls airbag deployment
power for the driver and front passenger. The driver airbag
system consists of the driver seat’s position sensor etc. The
front passenger’s airbag system consists of the front
passenger occupant classification sensor etc. In response to a severe frontal impact, the SRS front airbags
work with the seat belts to help reduce injury by inflating. The
SRS front airbags help reduce injuries mainly to the driver’s or
front passenger’s head or chest caused by hitting the vehicle
interior.
The SRS front passenger airbag will not activate if there is no
passenger sitting in the front passenger seat. However, the
front
passenger airbag may deploy if luggage is put in the seat,
or the seat belt is buckled up, regardless of the presence of an
occupant in the seat. (As for the front passenger occupant
classification system, see “Front passenger occupant
classification system” on page cxliii.)
Always wear your seat belt properly.

10Airbag sensor assembly
The SRS front airbag system consists mainly of the above
components, and their locations are shown in the illustration.
The airbag sensor assembly consists of a safing sensor and
airbag sensor. The front airbag sensors constantly monitor the forward
deceleration of the vehicle. If an impact results in a forward
deceleration beyond the designed threshold level, the system
triggers
the airbag inflators. At this time a chemical reaction in
the inflators very quickly fills the airbags with non− toxic gas to
help restrain the forward motion of the occupants. The front
airbags then quickly deflate, so that there is no obstruction of
the driver’s vision should it be necessary to continue driving.
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 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, primarily to the
head and chest, it may also cause other, less severe injuries
to the face, chest, arms and hands. These are usually in the
nature of minor burns or abrasions and swelling, but the force
of a deploying airbag can cause more serious injuries,
especially if an occupant’s hands, arms, chest or head are in
close proximity to the airbag module at the time of deployment.
This is why it is important for the occupant to: avoid placing any
object or part of the body between the occupant and the airbag
module; sit straight and well back into the seat; wear the
available seat belt properly; and sit as far as possible from the
airbag module, while still maintaining control of the vehicle.

OCCUPANT RESTRAINT SYSTEM
cxxviiiParts of the airbag module (steering wheel hub, airbag cover
and inflator) may be hot for several minutes after deployment,
so do not touch! The airbags inflate only once. The windshield
may be damaged by absorbing some of the force of the
inflating airbag.
CAUTION
The driver or front passenger who is too close to the
steering wheel or dashboard during airbag deployment
can be killed or seriously injured. Lexus strongly
recommends that:

The driver sit as far back as possible from the
steering wheel while still maintaining control of the
vehicle.
 The front passenger sit as far back as possible from
the dashboard.
 All vehicle occupants be properly restrained using
the available seat belts.
For instructions and precautions concerning the
seating position, see “Front seat precautions” on page
cv.
 Do not sit on the edge of the seat or lean over the
dashboard when the vehicle is in use, since the front
passenger airbag could inflates with considerable
speed and force. Anyone who is up against, or very
close to, an airbag when it inflates, can be killed or
seriously injured. Sit up straight and well back in the
seat, and always use your seat belt properly.

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.

clxviiiBy repeating these two steps and pressing the remaining
button,
the driving position for another driver can be recorded.
To set a new memorized position, select the desired position
and perform step 2. The previous memory will be erased and
the new position will be set.
To make only slight changes to an already memorized position,
the easiest way is to first activate the memorized position, then
make the desired changes and perform step 2 above.
Recalling the memorized position
When you push button “1” or “2”, the driving position will
be automatically adjusted to the position recorded for that
button. Conditions for memorized position activation

Ignition key “ON” and selector lever in “P” position
 Ignition switch off and within 30 seconds of opening driver’s
door
If any driving position memory switch is pushed while one of the
memorized driving position profiles is being activated, the
operation will stop.
To activate the system, push the desired button (“1” or “2”)\
again.
The driving position memory control system cannot be
operated while the vehicle is moving.
If the vehicle’s battery is disconnected, the computer’s
memory will be erased and the memorized positions will have
to be set again.
CAUTION
 Do not start the vehicle while the adjustments are
being made.
 Take care not to select the wrong button, or the seat
could strike the rear passenger or hit your body
against the steering wheel. If this happens, you can
stop the movement by pressing another driving
position memory switch.
