The indicator comes on when the ignition key is turned to
the ºONº position. It goes off after about 6 seconds. This
means the SRS airbags are operating properly.
This warning light system monitors the airbag sensor
assembly, front airbag sensors, side airbag sensors, curtain
shield airbag sensors, front seat belt pretensioner assemblies,
inflators, warning light, interconnecting wiring and power
sources. (For details, see ºService reminder indicators and
warning buzzersº on page 41.)
16G023
The front airbags are designed to activate in response to
a severe frontal impact within the shaded area between
the arrows in the illustration.
The front airbags will work if the severity of the impact is above
the designed threshold level, comparable to an approximate
25 km/h (15 mph) collision in the U.S.A. and 30 km (18 mph)
collision in Canada when impacting straight into a fixed barrier
that does not move or deform.
If the severity of the impact is below the above threshold level,
the front airbags may not work.
However, this threshold velocity will be considerably higher if
the vehicle strikes an object, such as a parked vehicle or sign
pole, which can move or deform on impact, or if it is involved
in an underride collision (e.g. a collision in which the nose of
the vehicle ºunderridesº, or goes under, the bed of a truck,
etc.).

sensor detection and activation the SRS airbags and seat belt
pretensioners will not operate all together.
For the safety of all occupants, always wear your seat belts
properly.
16G024
1Collision from the rear
2Vehicle rollover
The front airbags are not designed to inflate if the vehicle
is involved in a rear collision, if it rolls over, or if it is
involved in a low±speed frontal collision.
The side and curtain shield airbags are designed to inflate
when the passenger compartment area suffers a severe
impact from the side.
16G025
1Collision from the side at an angle
2Collision from the side to the vehicle body other
than the passenger compartment
The side and curtain shield airbags may not inflate if the
vehicle is subjected to a collision from the side at certain
angles, or a collision to the side of the vehicle body other
than the passenger compartment as shown in the
illustration.

The SRS 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 sensors.In a severe frontal impact, the driver and front passenger
airbag sensors detect deceleration and the system triggers the
front airbag inflators. In a severe side impact, the side and
curtain shield airbag sensor triggers the side and curtain shield
airbag inflator. Then a chemical reaction in the inflators quickly
fills the airbags with non±toxic gas to help restrain the forward
or lateral motion of the occupants.
When the SRS operates, it produces a fairly loud noise and
release some smoke and residue along with non±toxic gas.
This does not indicate a fire. This gas is normally harmless;
however, for those who have delicate skin, it may cause a
minor skin irritation. Be sure to wash off any residue as soon
as possible to prevent any potential skin irritation.
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.
Parts of the airbag module (steering wheel hub, dashboard,
front seats) may be hot for several minutes, but the airbags
themselves will not be hot. The airbags are designed to inflate
only once.
A crash severe enough to inflate the driver and front passenger
airbags may break the windshield as the vehicle buckles. In
vehicles with a front passenger airbag, the windshield may
also be damaged by absorbing some of the force of the
inflating airbag.

CAUTION
The SRS airbag system is designed only as a
supplement to the primary protection of the driver
side and front passenger side seat belt systems. The
front 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 or front
passenger can move forward 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 ºSeat beltsº on page 86.
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 seat of the vehicle and properly restrained.
The rear seat is the safest for infants and children.
For instructions concerning the installation of a child
restraint system, see ºChild restraintº on page 108 .
16G057a
Never put a rear±facing child restraint system on the
front passenger seat because the force of the rapid
inflation of the front passenger airbag can cause
death or serious injury to the child.

Move seat fully back
A forward±facing child restraint system should be
allowed to be put on the front passenger seat only
when it is unavoidable. Always move the seat as far
back as possible, because the force of the deploying
front passenger airbags could cause death or
serious injury to the child. Do not allow the child to
lean against the front door or around the front door
even if the child is seated in a child restraint system.
It is dangerous if the side and curtain shield airbag
inflates, and the impact could cause death or serious
injury to the child.
For instructions concerning the installation of a child
restraint system, see ºChild restraintº on page 108.
16G029a
Do not sit on the edge of the seat or lean over the
dashboard when the vehicle is in use. The front
passenger airbags inflate with considerable speed
and force; you may be killed or seriously injured. Sit
up straight and well back in the seat, and always use
your seat belt properly.

Do not lean against the front door when the vehicle
is in use. The side and curtain shield airbags inflate
with considerable speed and force; you may be killed
or seriously injured.
Do not apply excessive weight to the outer side of the
front seats.
16g244
Do not allow a child to kneel on the front passenger
seat facing the front passenger's side door when the
vehicle is in use. The side and curtain shield airbags
inflate with considerable speed and impact; the child
may be killed or seriously injured.

16G031a
Do not allow a child to stand up, or to kneel on the
front passenger seat. The front airbag inflates with
considerable speed and force; the child may be killed
or seriously injured.
Do not hold a child on your lap or in your arms. Use
a child restraint system in the rear seat. For
instructions concerning the installation of a child
restraint system, see ºChild restraintº on page 108.
16G032
Do not put objects or your pets on or in front of the
dashboard or steering wheel pad that houses the
driver and front passenger 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 things in their arms or on
their knees.
