The SRS side airbag and curtain shield
airbag system consists mainly of the fol-
lowing components, and their locations are
shown in the illustration.
1. SRS warning light
2. AIRBAG ONº and AIRBAG OFFº indi-
cator lights
3. Curtain shield airbag modules
(airbag and inflator)
4. Front passenger occupant classification
system (ECU and sensors)
5. Side airbag modules
(airbag and inflator)
6. Curtain shield airbag sensors
7. Side and curtain shield airbag sensors8. Front passenger 's seat belt buckle
switch
9. Airbag sensor assembly
The SRS side airbag and curtain shield
airbag system is controlled by the airbag
sensor assembly. The airbag sensor as-
sembly 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 occu-
pants.
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 imme-
diately.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 inju-
ries, it may also cause minor burns or
abrasions and swelling.
Front seats as well as parts of the front
and rear pillars, and roof side rail may be
hot for several minutes, but the airbags
themselves will not 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 in-
flate, the driver, front passenger and
second outside passengers must:

Wear their seat belts properly.

Remain properly seated with their
backs upright and against the seats
at all times.

Toyota strongly urges use of a
proper child restraint system which
conforms to the size of the child,
installed on the rear seat. Accord-
ing to accident statistics, the child
is safer when properly restrained in
the rear seat than in the front seat.

Never install a rear- facing child re-
straint system on the front passen-
ger seat even if the AIRBAG OFFº
indicator light is illuminated. In the
event of an accident, the force of
the rapid inflation of the front pas-
senger airbag can cause death or
serious injury to the child if the
rear- facing child restraint system is
installed on the front passenger
seat.

A forward- facing child restraint sys-
tem should be allowed to be
installed on the front passenger
seat only when it is unavoidable.
Always move the seat as far back
as possible even if the AIRBAG
OFFº indicator light is illuminated,
because the front passenger airbag
could inflate with considerable
speed and force. Otherwise, the
child may be killed or seriously in-
jured.

On vehicles with side airbags and
curtain shield airbags, do not allow
the child to lean his/her head or
any part of his/her body against the
door or the area of the seat, front
or rear pillar or roof side rail from
which the side airbags or curtain
shield airbags deploy even if the
child is seated in the child restraint
system. It is dangerous if the side
airbag and curtain shield airbag in-
flate, and the impact could cause
death or serious injury to the child.

Do not use the seat belt extender
when installing a child restraint
system on the front or rear passen-
ger seat. If installing a child re-
straint system with the seat belt
extender connected to the seat belt,
the seat belt will not securely hold
the child restraint system, which
could cause death or serious injury
to the child or other passengers in
the event of collision.

Make sure that you have complied
with all installation instructions pro-
vided by the child restraint
manufacturer and that the system is
properly secured. If it is not se-
cured properly, it may cause death
or serious injury to the child in the
event of a sudden stop or accident.

A child restraint system for a small
child or baby must itself be properly
restrained on the seat with the lap por-
tion of the lap/shoulder belt. You must
carefully consult the manufacturer 's in-
structions which accompany the child
restraint system.
To provide proper restraint, use a child
restraint system following the manufactur-
er 's instructions about the appropriate age
and size of the child for the child restraint
system.
Install the child restraint system correctly
following the instructions provided by its
manufacturer. General directions are also
provided under the following illustrations.
The child restraint system should be
installed on the rear seat. According to
accident statistics, the child is safer when
properly restrained in the rear seat than
in the front seat.
When not using the child restraint system,
keep it secured with the seat belt or place
it somewhere other than the passenger
compartment. This will prevent it from in-
juring passengers in the event of a sud-
den stop or accident.Child restraint systems are classified into
the following 3 types depending on the
child's age and size.
(A) Infant seat
(B) Convertible seat
(C) Booster seat
Install the child restraint system following
the instructions provided by its manufac-
turer.
Your vehicle has anchor brackets for se-
curing the top strap of a child restraint
system.
For instructions about how to use the an-
chor bracket, see ÐUsing a top strapº on
page 105 in this Section.
The child restraint lower anchorages ap-
proved for your vehicle may also be used.
See ÐInstallation with child restraint low-
er anchoragesº on page 107 in this Sec-
tion.

Do not install a child restraint sys-
tem on the second (or third) seat if
it interferes with the lock mecha-
nism of the front (or second) seats.
Otherwise, the child or front (or
second) seat occupant(s) may be
killed or seriously injured in case
of sudden braking or a collision.

If the driver 's seat position does
not allow sufficient space for safe
installation, install the child re-
straint system on the right second
seat.
Same angle Same position

When installing a child restraint
system in the second seat center
position, adjust both seat cushions
to the same position and align both
seatbacks at the same angle. Other-
wise, the child restraint system can-
