WARNING
■When using a child restraint
system
NEVER INSTALL A CHILD
RESTRAINT SYSTEM IN THE
FRONT PASSENGER’S SEAT
EVEN IF THE FRONT PASSEN-
GER’S SRS FRONTAL AIRBAG
IS DEACTIVATED. Be sure to
install it in the REAR seat in a cor-
rect manner. Also, it is strongly
recommended that any forward
facing child seat o r booster seat
be installed in the REAR seat, and
that even children who have out-
grown a child restraint system be
also seated in the REAR seat.
This is because children sitting in
the front passenger’s seat may be
killed or severely injured should
the front passenger’s SRS frontal
airbag deploy. REAR seats are
the safest place for children.
■General Precautions regard-
ing front passenger’s SRS
frontal airbag
When the front passenger's seat
is occupied by an adult, observe
the following precautions. Failure
to do so may lessen the load on
the front passenger 's seat, deacti-
vating the front passenger's SRS
frontal airbag despite the fact that
the seat is occupied by an adult.
This may result in personal injury.
●Do not allow the rear seat occu-
pant to lift the front passenger's
seat cushion using his/her feet.
●Do not place any article under
the front passenger's seat, or
squeeze any article from behind
and under the seat.
●Do not squeeze any article
between the front passenger's
seat and side trim /pillar, door or
center console box. This may lift
the seat cushion.
■When a small adu lt is seated
in the front passenger’s seat
When a small adult is seated in
the front passenger’s seat, the
Toyota advanced frontal airbag
system may or may not activate
the front passenger’s SRS frontal
airbag depending on the occu-
pant’s seating posture. If the OFF
indicator rema ins illuminated
while the ON indicator turns off
when a small adult is seated in
the front passenger's seat, refer to
P.43.
■General Precautions regard-
ing occupant detection sys-
tem
Do not kick the front passenger
seat or subject it to severe impact.
Otherwise, the SRS warning light
may illuminate to indicate a mal-
function of the front passenger
occupant detection system. In this
case, contact your Toyota dealer
immediately.
■After deployment
Do not touch the SRS airbag sys-
tem components around the
steering wheel and dashboard
with bare hands right after deploy-
ment. Doing so can cause burns
because the components can be
very hot as a result of deploy-
ment.

For safety and security
■SRS side airbag
The SRS side airbag is stored in
the door side of each front seat
seatback, which bears an “SRS
AIRBAG” mark.
In a moderate to severe side
impact collision, the SRS side
airbag on the impacted side of
the vehicle deploys between the
occupant and the door panel
and supplements the seatbelt by
reducing the impact on the
occupant’s chest and waist. The
SRS side airbag operates only
for front seat occupants.
■SRS curtain shield airbag
Your vehicle is equipped with a
SRS curtain shield airbag sys-
tem that complies with the Fed-
eral Motor Vehicle Safety
Standard (FMVSS) No. 226. The SRS curtain shield airbag
on each side of the cabin is
stored in the roof side (between
the front pillar and a point over
the rear seat). An “SRS AIR-
BAG” mark is located at the top
of each center pillar.
In a moderate to severe side
impact collision, the SRS curtain
shield airbag on the impacted
side of the vehicle deploys
between the occupant and the
side window and supplements
the seatbelt by reducing the
impact on the occupant’s head.
In a rollover, SRS curtain shield
airbags on both sides of the
vehicle deploy between the
occupant and the side window
and supplement the seatbelt by
reducing the impact to the occu-
pant’s head.
In an offset frontal collision, SRS
curtain shield airbags on both
sides of the vehicle deploy
between the occupant and the
side window and supplement
the seatbelt by reducing the
impact to the occupant’s head
and chest.
■Operation
The SRS side airbag and SRS
curtain shield airbag can func-
tion only when the engine switch
is in ON.
The following airbags deploy
independently of each other
since each has its own impact
NOTICE
If the device continues to cause
interference, the use of that
device in the vehicle should be
discontinued.

experienced in the passenger
compartment during a side
impact collision. That level dif-
fers from one type of collision to
another, and it may have no
bearing on the visible damage
done to the vehicle itself.
Example of the type of acci-
dent in which the SRS side
airbag will most likely deploy.
A severe side impa ct near the front
seat.
 Examples of the types of acci-
dents in which the SRS cur-
tain shield airbag will most
likely deploy.
• The vehicle is involved in a
severe side impac t near the front
seat or the rear seat.
• The vehicle rolls onto its side or the roof.
• The angle of vehicle tip-up is marginal or the skidding vehicle’s
tires hit a curbstone laterally.
• An offset frontal collision that is severe enough to deploy the front
airbag.
 Examples of the types of acci-
dents in which it is possible
that the SRS side airbag and
the SRS curtain shield airbag
will deploy.

• The vehicle is involved in a side-on impact from a motorcycle.
• The vehicle rolls onto its side or
the roof.
 Examples of the types of acci-
dents in which the SRS cur-
tain shield airbag is unlikely to
deploy.
There are many types of collisions
which might not necessarily require
SRS curtain shield airbag deploy-
ment. In the event of accidents like
those illustra ted, the SRS curtain
shield airbag may not deploy
depending on the level of accident
forces involved.
• The vehicle is involved in an oblique side-on impact. • The vehicle is involved in a
side-on impact in an area outside
the vicinity of the passenger com-
partment.
• The vehicle strikes a telephone pole or similar object.
• The vehicle is involved in a side-on impact from a motorcycle.
