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 to reduce injuries mainly to
the driver ’s or front passenger ’s chest and
the SRS curtain shield airbags help to
reduce injuries mainly to the driver ’s and
all window
−side passengers’ heads. The
SRS side airbag and curtain shield airbag
on the passenger side are activated even
with no passenger in the seat.
The curtain shield airbags may activate
even when the side airbags are not acti-
vated.
Be sure to wear your seat belt properly.
Your vehicle is equipped with a crash
sensing and diagnostic module, which will
record the use of the seat belt restraint
system by the driver and front passenger
when the SRS side airbags and curtain
shield airbags are inflated.

CAUTION
SRS side airbags and curtain shield
airbags inflate with considerable
force. To avoid potential death or se-
rious injury when they inflate, the
driver and all windowside passen-
gers must:
Wear their seat belts properly.
Remain properly seated with their
back upright and against the seat at
all times.
This indicator comes on when the igni-
tion key is turned to the “ON” position.
It goes off after about 6 seconds. This
means the SRS side airbags and curtain
shield airbags are operating properly.
This warning light system monitors the
airbag sensor assembly, front airbag sen-
sors, side and curtain shield airbag sen-
sors, curtain shield airbag sensors, driv-
er ’s seat position sensor, driver ’s seat belt
buckle switch, front seat belt pretensioner
assemblies, inflators, warning light, inter-
connecting wiring and power sources. (For
details, see “Service reminder indicators
and warning buzzers” on page 167 in Sec-
tion 1−5.)The SRS side airbag and curtain shield
airbag system 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 side airbags and curtain shield
airbags are designed to inflate when the
passenger compartment area suffers a se-
vere impact from the side.
For the safety of all occupants, 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 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. Curtain shield airbag modules (airbag and inflator)
3. Side airbag modules (airbag and inflator)
4. Curtain shield airbag sensors
5. Side and curtain shield airbag sensors
6. 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 and curtain shield airbag inflat-
ors and/or the curtain shield airbag inflat-
ors. 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 occupants.
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 gas is nor-
mally 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 desi gned to reduce serious inju-
ries, it may also cause minor burns or
abrasions and swelling.

Front seats as well as parts of all the
pillars, and roof side may be hot for sev-
eral minutes, but the airbags themselves
will not be hot. The airbags are designed
to inflate only once.
CAUTION
The SRS side airbag and curtain
shield airbag system is designed
only as a supplement to the prima-
ry protection of the driver side, and
all windowside passenger side seat
belt systems. To ensure maximum
protection in an accident, the driver
and all passengers in the vehicle
must wear their seat belts. Wearing
a seat belt during an accident re-
duces the chances of death or seri-
ous injury or being thrown out of
the vehicle. For instructions and
precautions concerning the seat
belt system, see “Seat belts” on
page 95 in this Section.
Improperly seated and/or restrained
infants and children can be killed
or seriously injured by a deploying
airbag. 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 infants and
children be placed in the rear seat
of the vehicle and properly re-
strained. The rear seat is the safest
for infants and children. For in-
structions concerning the installa-
tion of a child restraint system, see
“Child restraint” on page 121 in this
Section.Do not allow a child to lean his/her
head or any part of his/her body
against the side window or the area
of the seat, pillar or roof side from
which the side airbag and curtain
shield airbag deploy even if he/she
is seated in the child restraint sys-
tem. It is dangerous if the side air-
bag and curtain shield airbag in-
flate, and the impact could cause
death or serious injury to the child.
For instructions concerning the
installation of a child restraint sys-
tem, see “Child restraint” on page
121 in this Section.

Do not lean against the door when
the vehicle is in use, since the side
airbag and curtain shield airbag in-
flate with considerable speed and
force. Otherwise, you may be killed
or seriously injured. Special care
should be taken especially when
you have a small child in the ve-
hicle.
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 front
seats with a side airbag, and to the
front pillar, rear pillar and roof side
rail with a curtain shield airbag.
Do not get your head closer to the
area where the side airbag and cur-
tain shield airbag inflate, since
these airbags inflate with consider-
able speed and force. Otherwise,
you may be killed or seriously in-
jured. Special care should be taken
especially when you have a small
child in the vehicle.Do not allow a child to kneel on the
seat facing the side window, since
the side airbag and curtain shield
airbag inflate with considerable
speed and force. Otherwise, the
child may be killed or seriously in-
jured.

Do not get your head or hands out
of windows and do not allow a
child to do so. Since the curtain
shield airbags inflate with consider-
able speed and force, you may be
killed or seriously injured.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
part where the curtain shield airbag
activates such as on the windshield
glass, side door glass, front and
side pillars, roof side and assist
grips. When the curtain shield air-
bag inflates, the microphone or oth-
er device or object will be thrown
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. 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 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.
Do not disassemble or repair the
front pillar and roof side rail con-
taining the curtain shield airbags.
Such changes may disable the sys-
tem or cause the curtain shield air-
bags to inflate accidentally, result-
ing in death or serious injury.
Failure to follow these instructions
can result in death or serious injury.
Consult your Toyota dealer about any
repairs and modifications.
