■
If the front passenger’s frontal airbag ON indicator illuminates and the
OFF indicator turns off even when an in fant or a small child is in a child
restraint system (inc luding booster seat)
Turn the engine switch to the “LOCK” position if the front passenger’s frontal
airbag ON indicator illuminates and the OFF indicator turns off even when an
infant or a small child is in a child restraint system (including booster seat).
Remove the child restraint system from the seat. By referring to the child
restraint manufacturer’s recommendations as well as the child restraint sys-
tem installation procedures in “Child restraint systems” ( →P. 112), correctly
install the child restraint system. Turn the engine switch to the “ON” position
and make sure that the front passenger’s frontal airbag ON indicator turns
off and the OFF indicator illuminates.
If still the ON indicator remains illuminated while the OFF indicator turns off,
take the following actions.
● Ensure that no article is placed on the seat other than the child restraint
system and the child occupant.
● Ensure that the backward-forward position and seatback of front passen-
ger’s seat are locked into place securely by moving the seat back and
forth.
If the ON indicator still remains illuminated while the OFF indicator turns off
after taking relevant corrective actions described above, relocate the child
restraint system to the rear seat and immediately contact your Toyota dealer
for an inspection.
NOTE
When a child who has outgrown a child restraint system or a small adult is
seated in the front passenger’s seat, the Toyota advanced frontal airbag sys-
tem may or may not activate the front passenger’s SRS frontal airbag
depending on the occupant’s seating posture. The child should always wear
the seat belt when sitting in the seat irrespective of whether the airbag is
deactivated or activated. If the front passenger’s SRS frontal airbag is acti-
vated (the ON indicator remains illuminated while the OFF indicator turns
off), take the following actions.

If the passenger’s frontal airbag OFF indicator illuminates and the ON
indicator turns off even when the fr ont passenger’s seat is occupied by
an adult
This can be caused by the adult incorrectly sitting in the front passenger’s
seat. Turn the engine switch to the “LOCK” position. Ask the front passenger
to set the seatback to the upright position, sit up straight in the center of the
seat cushion, correctly fasten the seat belt, position his/her legs out forward,
and adjust the seat to the rearmost position. Turn the engine switch to the
“ON” position. If the OFF indicator remains illuminated while the ON indica-
tor remains off, take the following actions.
● Turn the engine switch to the “LOCK” position.
● Make sure that the front passenger does not use a blanket, seat cushion,
seat cover, seat heater or massager, etc.
● 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.
● Next, turn the engine switch to the “ON” position and wait 6 secon\
ds to
allow the system to complete self-checking. Following the system check,
both indicators turn off for 2 seconds. Now, the ON indicator should illu-
minate while the OFF indicator remains off.
If the OFF indicator still remains illuminated while the ON indicator remains
off, ask the occupant to move to the rear seat and immediately contact your
Toyota dealer for an inspection.

The SRS airbag can function only when the engine switch is in the “ON”
position.
The Toyota advanced frontal airbag system is designed to determine the
activation or deactivation condition of the front passenger’s SRS frontal air-
bag depending on the characteristic of the item(s) or person on the front
passenger’s seat monitored by the front passenger’s occupant classification
system sensor. 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 sys-
tem.
If the front sub sensors and the impact sensors in the airbag control module
detect a predetermined amount of force during a frontal collision, the control
module sends signals to the airbag modu
le(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 driver’s and front passenger’s SRS frontal airbags use dual stage infla-
tors. The two inflators of each airbag are triggered 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
characteristic of the item(s) or person on the seat in the case of the front
passenger’s SRS frontal airbag.
After deployment, the SRS airbag immediately starts to deflate so that t\
he
driver’s vision is not obstructed. The time required from detecting impact to
the deflation of the SRS airbag after deployment is shorter than the blink of
an eye.
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 passen-
ger’s seat belt pretensioners operate at the same time.
Although it is highly unlikely that the SRS airbag would activate in a non-
accident situation, should it occur, the SRS airbag will deflate quickly, not
obscuring vision and will not interfere with the driver's ability to maintain con-
trol of the vehicle.
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.

88 1-7. Safety information
■Operation
The SRS side airbag and SRS curtain shield airbag can function only when
the engine switch is in the “ON” position.
The driver’s and front passenger’s SRS side airbags and SRS curtain shield
airbags deploy independently of each other since each has its own impact
sensor. 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 front airbags in the steering wheel and
instrument panel.
A rollover sensor is also located inside the airbag control module.
An impact sensor, which senses impact force, is located in each of the left
and right center pillars, doors and rear wheel houses. Another impact sen-
sor, which also senses impact force, is located under the center of the rear
seats.
If the impact sensor that is located under the center of the rear seats and
one of the center pillar impact sensors or door impact sensors together
sense an impact force above a predetermined level in a side collision, the
control module causes both the SRS side airbag and curtain shield airbag on
the impacted side to inflate regardless of whether the rear wheel house
impact sensor on the same side senses an impact.
If the impact sensor that is located under the center of the rear seats and
one of the rear wheel house impact sensors together sense an impact force
above a predetermined level, the control module causes only the SRS cur-
tain shield airbag on the impacted side to inflate.
If the rollover sensor detects rollover of the vehicle, the control module
inflates the SRS curtain shield airbags. At this time, the driver's and front
passenger’s seat belt pretensioners also operate at the same time.
