WARNING
■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 a dult is seated
in the front passenger’s seat
When a small adult is seated in
the front passeng er’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 remains illuminated
while the ON indi cator turns off
when a small adult is seated in
the front passenger's seat, refer to
P. 4 5 .
■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.
NOTICE

■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

For safety and security
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
i m p a c t c o l l i s i o n , t h e S R S c u r t a i n
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
sensor. 
Driver’s SRS side airbag
 Front passenger’s SRS side
airbag
 SRS curtain shield airbag
(right-hand side)
 SRS curtain shield airbag
(left-hand side)
Therefore, they may not both
deploy in the same accident.
Also, the SRS side airbag and
SRS curtain shield airbag
deploys independently of the
driver’s and front passenger’s
SRS frontal airbags in the steer-
ing wheel and instrument panel.
For the locations of the sensors
and control modules, refer to
P. 2 9 .
■After deployment
After the deployment, the SRS
side airbag immediately starts to
deflate. The time required from
detection of an impact to defla-
tion of an SRS side airbag after
deployment is shorter than the
blink of an eye.
The SRS curtain shield airbag
remains inflated for a while fol-
lowing deployment then slowly
deflates.
The SRS side airbag and SRS
curtain shield airbag deploy
even when no one occupies the
seat on the side on which an
impact is applied.
When the SRS side airbag and
SRS curtain shield airbag

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.
It is possible that the SRS side and
curtain shield air bags will deploy if
a serious impact occurs to the underside of your vehicle. Some
examples are shown
in the illustra-
tion.
• Hitting a curb, edge of pavement or hard surface
• Falling into or jumping over a
deep hole
• Landing hard or vehicle falling

dents in which the SRS side
airbag is unlikely to deploy.

■Front passenger occupant
classification system precau-
tions
Observe the following precautions
regarding the front passenger
occupant classification system.
Failure to do so may cause the
occupant classifi cation system to
not function correctly, resulting in
death or serious injury.
●Wear the seat belt properly.
●Do not apply excessive force to
the seat.
●Do not put sharp object(s) on
the seat or pierce the seat
upholstery.
●Do not put objects under the
front passenger seat.
●Do not use a seat accessory,
such as a cushion or seat cover,
that covers the seat cushion
surface.
●Do not spill liqui d on the front
passenger seat. If liquid is
spilled, wipe it off immediately
and dry the seat. If the SRS
warning light illumi nates, dry the
seat until the warning light turns
off. If the SRS warning light
stays on even when the seat
has dried, do not allow anyone
to sit on the front passenger
seat and have the system
checked by your Toyota dealer.
If the SRS warning light does
not illuminate, check that the
airbag ON/OFF indicator light
works properly. If the indicator
light does not work properly, do
not allow anyone to sit in the
front passenger’s seat and have
the system inspected by your
Toyota dealer.
●Do not remove or disassemble
the front passenger seat. Also,
do not replace or modify the
seat upholstery or foam inside
the seat.
●Do not install any accessory
(such as an audio amplifier)
other than a genuine Toyota
accessory under t he front pas-
senger’s seat.
●Do not place a magnetized
items near the seat belt buckle.
●Never install a rearward facing
child seat in the front passen-
ger’s seat even if the front pas-
senger’s SRS frontal airbag is
deactivated. Be sure to install it
in the rear seat in a correct
manner. Also, it is strongly rec-
ommended that any forward
facing child seat or booster seat
be installed in the rear seat, and
that even children who have
outgrown a child restraint sys-
tem 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 passen-
ger’s SRS frontal airbag deploy.
Toyota believes that the rear
seats are the safest place for
children.
●If luggage or electronic devices
are placed on the front passen-
ger seat, the OFF indicator may
turn off and the ON indicator
may illuminate. If this occurs,
the front passenger’s airbag
may deploy during a collision. If
this is not desirable, remove the
luggage or electronic devices
from the front passenger seat.
