Passenger’s sideSRS AIRBAG deploy as soon
as a collision occurs.
After deployment, SRS AIR-
BAG start to deflate immedi-
ately so that the driver’s
vision is not obstructed.
The SRS airbags can function
only when the engine switch is
in ON.
The Toyota advanced frontal air-
bag system is designed to deter-
mine the activation or
deactivation condition of the
front passenger’s SRS frontal
airbag depending on the charac-
teristic of item(s) or person on
the front passenger’s seat moni-
tored by the front passenger’s
occupant detection system sen-
sor. For this reason, only the
driver’s SRS frontal airbag may
deploy in the event of a collision,
but this does not mean failure of
the system.
If the following sensors detect a predetermined amount of force
during a frontal collision, the
control module sends signals to
the airbag module(s) (only
driver’s module or both driver’s
and front passenger’s modules)
instructing the module(s) to
inflate the SRS frontal airbag(s).

The front impact sensors
 The impact sensors in the air-
bag control module
On the driver’s side, the SRS
knee airbag also inflates with
the SRS frontal airbag.
The driver’s and front passen-
ger’s SRS frontal airbags use
dual stage inflators. The two
inflators of each airbag are trig-
gered either sequentially or
simultaneously, depending on
the severity of impact, in the
case of the driver’s SRS frontal
airbag and depending on the
severity of impact and the char-
acteristic of item(s) or person on
the seat in the case of the front
passenger’s SRS frontal airbag.
■After deployment
After deployment, the SRS air-
bag immediately starts to deflate
so that the driver’s vision is not
obstructed and the driver’s abil-
ity to maintain control of the
vehicle is not impaired. The time
required from detecting impact
to the deflation of the SRS air-
bag after deployment is shorter
than the blink of an eye.
A

421-1. For safe use
Both when only the driver’s SRS
frontal airbag deploys and the
driver’s and front passenger’s
SRS frontal airbags deploy, the
driver’s and front passenger’s
seatbelt pretensioners operate
at the same time.
When the SRS airbag deploys,
a sudden, fairly loud inflation
noise will be heard and some
smoke will be released. These
occurrences are a normal result
of the deployment. This smoke
does not indicate a fire in the
vehicle.
■Example of the type of acci-
dent
The driver’s SRS frontal airbag
and front passenger’s SRS fron-
tal airbag are designed as fol-
lows.
 To deploy in the event of an
accident involving a moderate
to severe frontal collision
 To function on a one-time-only
basis
The driver’s SRS frontal airbag
and front passenger’s SRS fron-
tal airbag are not designed as
follows.
 To deploy in most lesser fron-
tal impacts
*1
To deploy in most side or rear
impacts or in most rollover
accidents
*2
*1: Because the necessary protec-
tion can be achieved by the seat- belt alone.
*2: Because deployment of only the
driver’s SRS fron tal airbag or
both the driver’s and front pas-
senger’s SRS frontal airbags
would not protect the occupant in
those situations.
SRS airbag deployment
depends on the level of force
experienced in the passenger
compartment during a collision.
That level differs from one type
of collision to another, and it
may have no bearing on the vis-
ible damage done to the vehicle
itself.
 Example of accident in which
the driver’s/driver’s and front
passenger’s SRS frontal air-
bag(s) will most likely deploy
A head-on collision against a thick
concrete wall at a vehicle speed of
12 to 19 mph (20 to 30 km/h) or
higher activates only the driver’s
SRS frontal airbag or both driver’s
and front passenger’s SRS frontal
airbags. The air bag(s) will also be
activated when the vehicle is
exposed to a front al impact similar
in fashion and magnitude to the col-
lision described above.
 Examples of the types of acci-

431-1. For safe use

For safety and security
dents in which it is possible
that the driver’s/driver’s and
front passenger’s SRS frontal
airbag(s) will deploy
Only the driver’s SRS frontal airbag
or both driver’s and front passen-
ger’s SRS frontal airbags may be
activated when the vehicle sustains
a hard impact in the undercarriage
area from the road surface (such as
when the vehicle plunges into a
deep ditch, is seve rely impacted or
knocked hard against an obstacle
on the road such as a curb).
 Examples of the types of acci-
dents in which deployment of
the driver’s/driver’s and front
passenger’s SRS frontal air-
bag(s) is unlikely to occur
There are many types of collisions
which might not necessarily require
deployment of driver’s/driver’s and
front passenger’s SRS frontal air-
bag(s). In the eve nt of accidents
like those illu strated, the
driver’s/driver’s and front passen-
ger’s SRS frontal airbag(s) may not
deploy depending on the level of
accident forces involved.
• The vehicle strikes an object, such as a telephone pole or sign
pole. • The vehicle slides under the load
bed of a truck.
• The vehicle sustains an oblique offset frontal impact.
• The vehicle sustains an offset frontal collision.

441-1. For safe use
• The vehicle strikes an object that can move or deform, such as a
parked vehicle.
 Examples of the types of acci-
dents in which the
driver’s/driver’s and front pas-
senger’s SRS frontal air-
bag(s) are not designed to
deploy in most cases
The driver’s and front passenger’s
SRS frontal ai rbags are not
designed to deploy in most of the
following cases.
• If the vehicle is struck from the side or from behind
• If the vehicle rolls onto its side or
roof • If the vehicle is involved in a
low-speed fron tal collision
In an accident where the vehicle
is impacted more than once, the
driver’s and/or front passenger’s
SRS frontal airbag(s) will deploy
only once on the first impact of
sufficient severity.
Example: In the case of a dou-
ble collision, first with another
vehicle, then against a concrete
wall in immediate succession,
once either or both of the
driver’s and front passenger’s
SRS frontal airbags is/are acti-
vated on the first impact, it/they
will not be activated on the sec-
ond impact.

If you think that the Front passen-
ger's frontal airb ag ON/OFF indica-
tor is incorrect, take the following
actions.
●Ensure that no article is placed on
the seat other than the occupant.
●Ensure that the backward-forward
position and seatback of front pas-
senger’s seat are locked into
place securely by moving the seat
back and forth.
If the ON indicator still remains illu-
minated while the OFF indicator
turns off after taking relevant correc-
tive actions descr ibed above, imme-
diately contact your Toyota dealer
for an inspection.

dealer inspection, it is recom-
mended that on subsequent trips
the small adult alwa ys take the rear
seat.

461-1. For safe use
■If the passenger’s frontal airbag
OFF indicator illuminates and
the ON indicator turns off even
when the front passenger’s seat
is occupied by an adult
This can be caused by the adult
incorrectly sitting in the front pas-
senger’s seat.
1 Turn the engine switch off.
2 Ask the front passenger to set
the seatback to the upright posi-
tion, sit up straight in the center
of the seat cushion, correctly fas-
ten the seatbelt, position his/her
legs out forward, and adjust the
seat to the rearmost position.
3 Turn the engine switch to ON.
If the OFF indicator remains illumi-
nated while the ON indicator
remains off, take the following
actions.
1 Turn the engine switch off.
2 Make sure that the front passen-
ger does not use a blanket, extra
seat cushion, sea t cover, extra
seat heater or massager, etc.
3 If wearing excessive layers of
clothing, the front passenger
should remove any unnecessary
items before sitting in the front
passenger’s seat, or should sit in
a rear seat.
4 Turn the engine switch to ON
and wait 6 seconds to allow the
system to complete self-check-
ing. Following the system check,
both indicators turn off for 2 sec-
onds. Now, the ON indicator
should illuminate while the OFF
indicator remains off.
If the OFF indicator still remains illu-
minated while the ON indicator
remains off, ask the occupant to
move to the rear seat and immedi-
ately contact your Toyota dealer for
an inspection.■If the seatbelt buckle switch
and/or front passenger’s occu-
pant detection system have
failed
If the seatbelt buckle switch and/or
front passenger’s occupant detec-
tion system have failed, the SRS
warning light will illuminate. Have
the system inspected by your Toyota
dealer immediately if the SRS warn-
ing light illuminates.
■When to contact your Toyota
dealer
If your vehicle has sustained impact,
this may affect the proper function of
the Toyota advanced frontal airbag
system. Have your vehicle
inspected at your Toyota dealer. Do
not use the front passenger’s seat
while driving the vehicle to your Toy-
ota dealer.
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 or 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.

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
■Toyota advanced frontal air-
bag system precautions
Observe the following precau-
tions. Failure to do so may pre-
vent the Toyota advanced frontal
airbag system from functioning
correctly or cause the system to
fail.
●Do not apply any strong impact
to the front passenger’s seat
such as by kicking.
●Do not let rear passengers rest
their feet between the front
seatback and seat cushion.
●Do not spill liquid on the front
passenger’s seat. If liquid is
spilled, wipe it o ff immediately.
●Do not remove or disassemble
the front passenger’s seat.

481-1. For safe use
■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
NOTICE
●Do not install any accessory
(such as an audio amplifier)
other than a genuine Toyota
accessory under the front pas-
senger’s seat.
●Do not place anything (shoes,
umbrella, etc.) under the front
passenger’s seat.
●Do not place any objects
(books, etc.) around the front
passenger’s seat.
●Do not use the front passen-
ger’s seat with the head
restraint removed.
●Do not leave any articles on the
front passenger’ s seat or the
seatbelt tongue and buckle
engaged when you leave your
vehicle.
●Do not put sharp object(s) on
the seat or pierce the seat
upholstery.
●Do not place a magnet near the
seatbelt buckle and the seatbelt
retractor.
●Do not use front seats with their
backward-forward position
adjuster and seatback adjuster
not being locked into place
securely. If any of them are not
locked securely, adjust them
again. For adjusting procedure,
refer to P.119.
■When using the front passen-
ger’s seat
Observe the following precautions
as it increase the load on the front
passenger's seat and not work
properly.
●Do not install any accessory
such as a table or TV onto the
seatback.
●Do not allow the rear seat occu-
pant to place his/her hands or
legs on the front passenger's
seatback, or allow him/her to
pull the seatback.
SRS side airbag and SRS
curtain shield airbag

491-1. For safe use
1
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

501-1. For safe use
deploy, a sudden, fairly loud
inflation noise will be heard and
some smoke will be released.
These occurrences are a normal
result of the deployment. This
smoke does not indicate a fire in
the vehicle.
■Example of the type of acci-
dent
The SRS side airbag and SRS
curtain shield airbag are
designed as follows:
 To deploy in the event of an
accident involving a moderate
to severe side impact collision
 To function on a one-time-only
basis.
The SRS side airbag and SRS
curtain shield airbag are not
designed to deploy in the follow-
ing cases:
 In most lesser side impact
 In most frontal or most rear
impacts (because the SRS
side airbag and SRS curtain
shield airbag deployment
would not protect the occu-
pant in those situations)
The SRS curtain shield airbags
are also designed to deploy
when the vehicle is in an
extremely inclined state such as
during a rollover. They are not
designed to deploy in most
lesser inclined states.
SRS side airbag and SRS cur-
tain shield airbag deployment depend on the level of force
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 impact 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 impact near the front
seat or the rear seat.
• The vehicle rolls o nto its side or
the roof.
