102 1-7. Safety information
■If the passenger’s frontal airbag OFF indicator illuminates and the ON
indicator turns off even when the front passenger’s seat is occ upied by
an adult
This can be caused by the adult incorrectly sitting in the fron t passenger’s
seat. Turn the engine switch to the “LOCK” position (vehicles w ithout a smart
key system), or turn the “ENGINE START STOP” switch off (vehicl es with a
smart key system). 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 ad just the seat to
the rearmost position. Turn the engine switch to the “ON” posit ion (vehicles
without a smart key system), or turn the “ENGINE START STOP” sw itch to
IGNITION ON mode (vehicles with a smart key system). If the OFF indicator
remains illuminated while the ON indicator remains off, take th e following
actions.
● Vehicles without a smart key system:
Turn the engine switch to the “LOCK” position.
Vehicles with a smart key system:
Turn the “ENGINE START STOP” switch off.
● 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 se conds to
allow the system to complete self-checking. Following the syste m 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 ind icator remains
off, ask the occupant to move to the rear seat and immediately contact your
Toyota dealer for an inspection.

104 1-7. Safety information
The SRS airbag can function only when the engine switch is in the “ON”
position (vehicles without a smart key system) or when the “ENGINE START
STOP” switch is in IGNITION ON mode (vehicles with a smart key system).
The Toyota advanced frontal airbag system is designed to determ ine the
activation or deactivation condition of the front passenger’s S RS 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 cl assification
system sensor. For this reason, only the driver’s SRS frontal a irbag may
deploy in the event of a collision, but this does not mean fail ure of the sys-
tem.
If the front sub sensors and the impact sensors in the airbag c ontrol module
detect a predetermined amount of force during a frontal collisi on, the control
module sends signals to the airbag module(s) (only driver’s mod ule 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 seq uentially or
simultaneously, depending on the severity of impact, in the cas e of the
driver’s SRS frontal airbag and depending on the severity of im pact 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 the
driver’s vision is not obstructed. The time required from detec ting impact to
the deflation of the SRS airbag after deployment is shorter tha n 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 activa te in a non-
accident situation, should it occur, the SRS airbag will deflat e quickly, not
obscuring vision and will not interfere with the driver's abili ty to maintain con-
trol of the vehicle.
When the SRS airbag deploys, a sudden, fairly loud inflation no ise 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 i n the vehicle.

Operation
The SRS side airbag and SRS curtain shield airbag can function only when
the engine switch is in the “ON” position (vehicles without a s mart key sys-
tem) or when the “ENGINE START ST OP” switch is in IGNITION ON mode
(vehicles with a smart key system).
The driver’s and front passenger’s SRS side airbags and SRS cur tain shield
airbags deploy independently of each other since each has its o wn impact
sensor. Therefore, they may not both deploy in the same acciden t. Also, the
SRS side airbag and SRS curtain shield airbag deploys independe ntly of the
driver’s and front passenger’s SRS front airbags in the steerin g wheel and
instrument panel.
A rollover sensor is also located inside the airbag control mod ule.
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 re ar 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 col lision, the
control module causes both the SRS side airbag and curtain shield airbag on
the impacted side to inflate regardless of whether the rear whe el house
impact sensor on the same side senses an impact.
If the impact sensor that is located under the center of the re ar seats and
one of the rear wheel house impact sensors together sense an im pact 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 ti me.

SRS airbag system monitors
A diagnostic system continually
monitors the readiness of the
SRS airbag system (including
front seat belt pretensioners)
while the vehicle is being driven.
The SRS warning light will show
normal system operation by illu-
minating for approximately 6
seconds when the engine switch
is turned to the “ON” position
(vehicles without a smart key
system), or the “ENGINE START
STOP” switch is turned to IGNI-
TION ON mode (vehicles with a
smart key system).
The following components are mo nitored by the indicator:
● Front sub sensor (right-hand side)
● Front sub sensor (left-hand side)
● Airbag control module (including impact sensors and rollover se n-
sors)
● Frontal airbag modu le (driver’s side)
● Frontal airbag module ( front passenger’s side)
● Side airbag sensor (center pillar right-hand side)
