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 module for front passenger (airbag and inflator)
4. “AIRBAG ON” and “AIRBAG OFF” indi- cator lights
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 air bags 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 im-
mediately. 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, 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 seri-
ous injuries, especially if an occupant’s
hands, arms, chest or head is 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 ve-
hicle.
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 inflat-
ing 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.
Toyota strongly recommends that:
The driver sit as far back as pos-
sible from the steering wheel while
still maintaining control of the ve-
hicle.
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 con-
cerning the seating position, see
“—Front seat precautions” on page
58 in this Section.Do not sit on the edge of the seat
or lean against the dashboard when
the vehicle is in use, since the
front passenger airbag could inflate
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.Toyota 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 rear seat. For instruc-
tions concerning the installation of
a child restraint system, see “Child
restraint” on page 139 in this Sec-
tion.

2007 SIENNA from Oct. ’06 Prod. (OM45437U)
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 sys-
tem. They might restrict inflation or
cause death or serious injury as
they are projected rearward by the
force of the deploying airbags. Like-
wise, the driver and front passenger
should not hold objects in their
arms or on their knees.
Do not modify or remove any wir-
ing. Do not modify, remove, strike
or open any components such as
the steering wheel pad, steering
wheel, column cover, dashboard
near the front passenger airbag,
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 sys-
tem, which could result in death or
serious injury.
Failure to follow these instructions
can result in death or serious injury.
Consult your Toyota dealer about any
repair and modification.
If you wish to modify your vehicle for
a person with a physical disability,
consult your Toyota dealer. It may
dangerously interfere with the SRS
front airbags operation.NOTICE
Do not perform any of the following
changes without consulting your
Toyota dealer. Such changes can in-
terfere 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 compact
disc player
 Modification of the suspension sys-
tem
 Modification of the front end struc-
ture
 Attachment of a grille guard (bull
bar, kangaroo bar, etc.), snowplow,
winches or any other equipment to
the front end

This indicator comes on when the igni-
tion switch is turned to the “ON” posi-
tion. It goes off after about 6 seconds.
This means the SRS front airbags are
operating properly.This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sensor
assemblies, curtain shield airbag sensor
assemblies, driver ’s seat position sensor,
driver’s seat belt buckle switch, front pas-
senger occupant classification system,
“AIRBAG ON” indicator light, “AIRBAG
OFF” indicator light, front passenger ’s seat
belt buckle switch, seat belt pretensioner
assemblies, inflators, interconnecting wir-
ing and power sources. (For details, see
“Service reminder indicators and warning
buzzers” on page 191 in Section 1
−6.)
If any of the following conditions occurs,
this indicates a malfunction of the airbags
or seat belt pretensioners. Contact your
Toyota dealer as soon as possible.
When the ignition key is turned to the
“ON” position, the light does not come
on, remains on for more than 6 sec-
onds or flashes.
The light comes on or starts flashing
while driving. If the light stays on, it indicates that the
SRS driver and front passenger airbag
system and/or front passenger occupant
classification system and “AIRBAG ON”
and “AIRBAG OFF” indicator lights have a
problem. If the light flashes, the SRS side
airbag system and/or curtain shield airbag
system have a problem.
The SRS warning light and “AIRBAG OFF”
indicator light will come on if there is a
malfunction in the front passenger occu-
pant classification system.

In the following cases, contact your Toyota
dealer as soon as possible:
The SRS front airbags have been in-
flated.
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 dashboard (shaded in the illustra-
tion) is scratched, cracked, or other-
wise damaged.
NOTICE
Do not disconnect the battery cables
before contacting your Toyota dealer.
The SRS (Supplemental Restraint Sys-
tem) side airbags and curtain shield air-
bags are designed to provide further
protection for the driver and all win-
dowside passengers in addition to the
primary safety protection provided by
the seat belts.
In response to a severe side impact, the
SRS side airbags and curtain shield air-
bags work with the seat belts to help
reduce injury by inflating. The SRS side
airbags help reduce injuries mainly to the
driver ’s or front passenger ’s chest and the
SRS curtain shield airbags help reduce
injuries mainly to the driver’s and all win-
dow −side passengers’ heads.

The SRS side airbag on the passenger
seat will not activate if there is no pas-
senger sitting in the front passenger seat.
However, the side airbag on the passen-
ger seat may deploy if luggage is put on
the seat, or the seat belt is buckled up
regardless of the presence of the occu-
pant in the seat. (As for the front passen-
ger occupant classification system, see
“—Front passenger occupant classification
system” on page 135 in this Section.)
The SRS curtain shield airbag on the pas-
senger side are activated even with no
passenger in the front seat or all window−
side seat.
The SRS curtain shield airbags may acti-
vate even when the side airbags are not
activated.
Always wear your seat belt properly.CAUTION
The SRS side airbag and curtain
shield airbag system is designed
only as a supplement to the prima-
ry protection of the driver and all
windowside passenger seat belt
systems. 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 con-
cerning the seat belt system, see
“Seat belts” on page 108 in this Sec-
tion.
Do not allow anyone to lean his/her
head or any part of his/her body
against the side window or the area
of the seat, front or side pillars or
roof side rail from which the SRS
side airbag and curtain shield air-
bag deploy even if he/she is a child
seated in the child restraint system.
It is dangerous if the SRS side air-
bag and curtain shield airbag in-
flate, and the impact of the deploy-
ing airbag could cause death or se-
rious injury to the occupant.
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
139 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 buckleswitch
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 air bags 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 front and
side pillars, and roof side rails may be hot
for several minutes, but the airbags them-
selves 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 and all windowside
passengers must:
Wear their seat belts properly.
Remain properly seated with their
backs upright and against the seats
at all times.
Do not allow anyone to lean against
the door when the vehicle is in use,
since the side airbag and curtain
shield airbag could inflate with con-
siderable speed and force. Other-
wise, he/she may be killed or seri-
ously injured. Special care should
be taken especially when you have
a small child in the vehicle.
Sit up straight and well back in the
seat, distributing your weight evenly
in the seat. Do not apply excessive
weight to the outer side of the
seats with a side airbag, and to the
front and side pillars and roof side
rail with a curtain shield airbag.

Do not allow anyone to get his/her
head closer to the area where the
side airbag and curtain shield air-
bag inflate, since these airbags
could inflate with considerable
speed and force. Otherwise, he/she
may be killed or seriously injured.
Special care should be taken espe-
cially when you have a small child
in the vehicle.Do not allow anyone to kneel on
the seat facing the side window,
since the side airbag and curtain
shield airbag could inflate with con-
siderable speed and force. Other-
wise, he/she may be killed or seri-
ously injured. Special care should
be taken especially when you have
a small child in the vehicle.Do not allow anyone to get his/her
head or hands out of windows
since the curtain shield airbags
could inflate with considerable
speed and force. Otherwise, he/she
may be killed or seriously injured.
Special care should be taken espe-
cially when you have a small child
in the vehicle.

Do not attach a cup holder or any
other device or object on or around
the door. When the side airbag in-
flates, 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 attach a microphone or any
other device or object around the
area where the curtain shield airbag
activates such as on the windshield
glass, side door glass, front or side
pillars, roof side rails and assist
grips. When the curtain shield air-
bag inflates, the microphone or oth-
er device or object will be thrown
away with great force or the curtain
shield airbag may not activate cor-
rectly, resulting in death or serious
injury.
Do not hook a hanger, heavy or
sharp pointed objects on the coat
hook. If the curtain shield airbag
inflates, those items will be thrown
away with great force or the curtain
shield airbag may not activate cor-
rectly, resulting in death or serious
injury. When you hang clothes,
hang them on the coat hook direct-
ly.
Do not use seat accessories which
cover the parts where the side air-
bags inflate. Such accessories may
prevent the side airbags from acti-
vating correctly, causing death or
serious injury.
Do not modify or replace the seats
or upholstery of the seats with side
airbags. Such changes may prevent
the side airbag system from activat-
ing correctly, disable the system or
cause the side airbags to inflate ac-
cidentally, resulting in death or seri-
ous injury.
