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 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.
Parts 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
112.
 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.

Lexus strongly recommends that all infants and
children be placed in the rear seat of the vehicle and
be properly restrained.
 Do not hold a child on your lap or in your arms. Use
a child restraint system in the second or third seat.
For instructions concerning the installation of a child
restraint system, see “Child restraint” on page 175.Do not put anything or any part of your body on or in
front of the dashboard or steering wheel pad that
houses the front airbag system. They might restrict
inflation or cause death or serious injury as they are
projected rearward by the force of the deploying
airbags. Likewise, the driver and front passenger
should not hold objects in their arms or on their
knees.

Do not modify or remove any wiring. Do not modify,
remove, st rike or open any components, such as the
steering wheel pad, steering wheel, column cover,
front passenger airbag cover, front passenger airbag
or airbag sensor assembly. Doing so may prevent the
front airbag system from activating correctly, cause
sudden activation of the system or disable the
system, which could result 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.
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 front 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 front 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 front end structure
 Attachment of a grille guard (bull bar, kangaroo bar,
etc.), snowplow, winches or any other equipment to
the front end
 Repairs made on or near the front fenders, front end
structure, console, steering column, steering wheel
or dashboard near the front passenger airbag

In the following cases, contact your Lexus dealer as soon as
possible:
The SRS front airbags have been inflated.
 The front of the vehicle (shaded in the illustration) was
involved in an accident that was not severe enough to cause
the SRS front airbags to inflate.
 The pad section of the steering wheel or front passenger
airbag cover (shaded in the illustration) is scratched,
cracked, or otherwise damaged.
NOTICE
Do not disconnect the battery cables before contacting
your Lexus dealer.

DRIVING POSITION MEMORYSYSTEM
A microcomputer will memorize the position of the driver’s
seat, and the positions of the tilt and telescopic steering, and
outside rear view mirrors. Two dif ferent driving position profiles
can be entered into the computer’s memory.
Recording the driving position in the computer’s memory can
only be done when the ignition key is in the “ON” position and
the selector lever is in the “P” position.
Setting the driving position
1. Adjust the driver’s seat, tilt and telescopic steering and
outside rear view mirrors to the desired position.
2. While pushing the “SET” button, push button “1” or “2”
until the signal beeps. The beep sound means that the positions are recorded in the
computer’s memory.
By 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.

OCCUPANT RESTRAINT SYSTEMS
199
Conditions for memorized position activation

Ignition key “ON” and selector lever in “P” position.
All parts of the memorized positions can be activated.
 Key not in ignition switch and within 30 seconds of opening
driver’s door.
The memorized position can be activated, except for the tilt
and telescopic steering.
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.
