The SRS front airbags may also deploy
if a serious impact occurs to the under-
side of your vehicle. Some examples
are shown in the illustration.The SRS front airbag system consists
mainly of the following components, and
their locations are shown in the illustra-
tion. 1. Front airbag sensors
2. SRS warning light
3. “AIRBAG ON” and “AIRBAG OFF” indi- cator lights
4. Airbag module for front passenger (airbag and inflator)
5. Front passenger occupant classification system (ECU and sensors)
6. Front passenger ’s seat belt buckle switch
7. Driver ’s seat belt buckle switch 8. Driver ’s seat position sensor
9. Airbag sensor assembly
10. Airbag module for driver (airbag and inflator)
The airbag sensor assembly consists of a
safing sensor and airbag sensor.
The front airbag sensors constantly moni-
tor the forward deceleration of the vehicle.
If an impact results in a forward decelera-
tion beyond the designed threshold level,
the system triggers the airbag inflators. At
this time a chemical reaction in the infla-
tors 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 can safely exit
from the vehicle, you should do so imme-
diately.

Improperly seated and/or restrained
infants and children can be killed
or seriously injured by the deploy-
ing airbags. An infant or child who
is too small to use a seat belt
should be properly secured using a
child restraint system. Toyota
strongly recommends that all in-
fants and children be placed in the
rear seats of the vehicle and prop-
erly restrained. The rear seats are
the safest for infants and children.
For instructions concerning the
installation of a child restraint sys-
tem, see “Child restraint” on page
76 in this Section.
The SRS side airbag and curtain shield
airbag system may not activate 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 side airbags and curtain shield
airbags are designed to inflate when the
passenger compartment area suffers a se-
vere impact from the side.
Always wear your seat belts properly.
Collision from the rear
Collision from the front Vehicle rollover
The SRS side airbags and curtain shield
airbags are not generally designed to
inflate if the vehicle is involved in a
front or rear collision, if it rolls over,
or if it is involved in a lowspeed side
collision.

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 ON” and “AIRBAG OFF” 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 sensors 8. 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 desi
gned 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
rear 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 rearfacing child re-
straint system on the front passen-
ger seat even if the “AIRBAG OFF”
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
rearfacing child restraint system is
installed on the front passenger
seat.
A forwardfacing 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
OFF” 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 you have complied with
all installation instructions provided
by the child restraint manufacturer
and that the system is properly se-
cured. If it is not secured properly,
it may cause death or serious injury
to the child in the event of a sud-
den 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 in the trunk or somewhere other than
the passenger compartment. This will pre-
vent it from injuring passengers in the
event of a sudden 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 “—Using a top strap” on
page 89 in this Section.
The child restraint lower anchorages ap-
proved for your vehicle may also be used.
See “—Installation with child restraint low-
er anchorages” on page 91 in this Sec-
tion.

4. To remove the infant seat, press thebuckle release button and allow the
belt to retract completely. The belt will
move freely again and be ready to
work for an adult or older child passen-
ger.(B) CONVERTIBLE SEAT INSTALLATION
A convertible seat must be used in for-
wardfacing or rearfacing position de-
pending on the age and size of the
child. When installing, follow the
manufacturer ’s instructions about the
applicable age and size of the child as
well as directions for installing the
child restraint system. Install the child restraint system on the
front passenger seat only when it is un-
avoidable. Your vehicle is equipped with a
front passenger occupant classification
system. In order to activate the occupant
classification system correctly, install the
forward
−facing child restraint system on
the front passenger seat in the following
order:
1. Turn the ignition key to the “ON” posi- tion.
2. Move the front passenger seat to the rearward position.
3. Put the child restraint system on the front passenger seat without putting
your weight on the front passenger
seat.
4. Insert the seat belt tab into the seat belt buckle.
5. Fully extend the shoulder belt to put it in the lock mode. When the belt is
then retracted even slightly, it cannot
be extended. To hold the seat securely,
make sure the belt is in the lock mode
before letting the belt retract.

6. While pressing the convertible seatfirmly against the seat cushion and
seatback, let the shoulder belt retract
as far as it will go to hold the convert-
ible seat securely.
CAUTION
Push and pull the child restraint sys-
tem in different directions to be sure
it is secure. Follow all the installation
instructions provided by its manufac-
turer.
7. Put a child on the child restraint sys-tem and secure the child, complying
with the instructions provided by the
child restraint system manufacturer. The “AIRBAG OFF” indicator light should
be illuminated when the ignition key is
“ON” and the child is in the child restraint
system after following these proc
edures.
The “AIRBAG OFF” indicator light indi-
cates the SRS front passenger airbag and
side airbag on the passenger side will not
deploy. If the “AIRBAG ON” indicator light
is illuminated, remove the child restraint
system and reinstall it with the ignition
key in the “ACC” or “LOCK” position. If
the “AIRBAG ON” indicator light is illumi-
nated when the ignition key is turned to
the “ON” position, then the SRS front pas-
senger airbag and side airbag on the pas-
senger side may deploy in an accident.
Do not drive the vehicle in this condition.
Remove the child restraint system and
contact your Toyota dealer.
CAUTION
Never install a rearfacing child re-
straint system on the front passen-
ger seat. A forwardfacing child re-
straint system should only be
installed on the front passenger
seat when unavoidable. If you must
install the child restraint system on
the front passenger seat, put the
seat in its most rearward position,
and install the forwardfacing child
restraint system in the proper or-
der. Otherwise, the front passenger
occupant classification system can
not detect the presence of the child
restraint system and the front pas-
senger airbag and side airbag on
the front passenger seat could
deploy.
