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 co llision, 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 83.
Improperly seated and/or restrained infants and
children can be killed or seriously injured by the
deploying front 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 104 .

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 104.
SV16065
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 objects in their arms or on
their knees.

SV16066
Do not attach a cup holder or any other device or
object on or around the door. When the side airbag
inflates, the cup holder or any other device or object
will be thrown with great force, or the side airbag may
not activate correctly, resulting in death or serious
injury. Likewise, the driver and front passenger
should not hold objects in their arms or on their
knees.
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 remove any wiring. Do not modify,
remove, strike or open any components, such as the
steering wheel pad, steering wheel, column cover,
front passenger airbag cover, front seats or airbag
sensor assembly. Doing so may cause sudden SRS
front airbag inflation or disable the system, which
could result in death or serious injury.
Do not modify or replace the seats or the upholstery
of front seats with side airbags. Such changes may
disable the system or cause the side 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 if you insist
on modifications of this kind.

This SRS front airbag system has an indicator to inform the
driver of operating problems. If either of the following
conditions occurs, this indicates a malfunction of the airbags.
Contact your Lexus dealer as soon as possible to service the
vehicle.
When the ignition key is turned to the ºACCº or ºONº
position, the light does not come on, stays on or flashes.
The light comes on or starts flashing while driving.
If the light stays on, it indicates that the driver and front
passenger airbags fail. If the light flashes, the side airbags fail.

In the following cases, contact your Lexus dealer as soon as
possible:
Any of the SRS airbags have been inflated.
The front of the vehicle and portion of the doors (shaded in
the illustration) were involved in an accident that was not
severe enough to cause the SRS airbags to inflate.

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
