72 1-7. Safety information
Your vehicle is equipped with ADVANCED AIRBAGS designed based
on US motor vehicle safety standards (FMVSS208). The airbag sys-
tem controls airbag deployment power for the driver and front pas-
senger. The front passenger's airbag system consists of the front
passenger occupant detect ion control module etc.
The main SRS airbag system components are shown above. The
SRS airbag system is controlled by the airbag control module. The
airbag control module consists of an airbag sensor.
In certain types of severe front or side impacts, the SRS airbag sys-
tem triggers the airbag inflators. A chemical reaction in the inflators
quickly fills the airbags with non-toxic gas to help restrain the motion
of the occupants.

If the SRS airbags deploy (inflate)
●Slight abrasions, burns, bruising etc., may be sustained from SRS air-
bags, due to the extremely high speed deployment (inflation) by hot
gases.
● A loud noise and white powder will be emitted.
● Parts of the airbag module (steering wheel hub, airbag cover and inflator)
as well as the front seats, parts of the front and rear pillars, and roof side
rails, may be hot for several minutes. The airbag itself may also be hot.
● The windshield may crack.

74 1-7. Safety information
■Driver’s SRS frontal airbag
The driver’s SRS frontal airbag uses a dual stage inflator. The inflator oper-
ates in different ways depending on the severity of impact.
Have the system inspected by your Toyota dealer immediately if the SRS
warning light illuminates.
NOTE
The driver’s SRS side airbag and SRS curtain shield airbag are not con-
trolled by the Toyota advanced frontal airbag system.
■ Front passenger’s SRS frontal airbag
The front passenger’s SRS frontal airbag uses a dual stage inflator. The
inflator operates in different ways depending on the severity of impact.
The occupant classification system sensor is installed under the seat uphol-
stery and monitors the physique and posture of the front passenger. Using
this information, the occupant classification system determines whether \
the
front passenger’s SRS frontal airbag should be deployed or not.
The occupant classification system may not inflate the front passenger’s
SRS frontal airbag even when the driver’s SRS frontal airbag deploys. This
is normal. In this case, although the front passenger’s SRS frontal airbag
does not operate, the front passenger’s seat belt pretensioner operates with
the driver’s seat belt pretensioner. For details about the seat belt preten-
sioner, refer to “Seat belt pretensioners”. ( →P. 43)
Observe the following precautions. Failure to do so may prevent the Toyota
advanced frontal airbag system from functioning correctly or cause the sys-
tem to fail.
● Do not apply any strong impact to the front passenger’s seat.
● Do not spill liquid on the front passenger’s seat. If liquid is spilled, wipe it
off immediately.
● Do not remove or disassemble the front passenger’s seat.
● Do not install any accessory (such as an audio amplifier) other than a
genuine Toyota accessory under the front passenger’s seat.
● Do not place anything (shoes, umbrella, etc.) under the front passenger’s
seat.
● Do not place a magnet near the seat belt buckle.

Before driving
If the seat belt buckle switch and/or front passenger’s occupant classification
system have failed, the SRS warning light will illuminate. Have the system
inspected by your Toyota dealer immediately if the SRS warning light illumi-
nates.
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 Toyota dealer.
NOTE
The front passenger’s SRS side airbag an
d SRS curtain shield airbag are
not controlled by the Toyota advanced frontal airbag system.
■ Passenger’s frontal airbag ON and OFF indicators
→P. 104
■ Occupant classification system
The occupant classification system sensor is installed under the seat uphol-
stery and monitors the physique and posture of the front passenger. Using
this information, the occupant classification system determines whether the
front passenger’s SRS frontal airbag should be deployed or not.
If the front passenger’s seat cushion is wet, this may adversely affect the
ability of the system to determine deployment. If the seat cushion is wet, the
front passenger should stop sitting on the front passenger’s seat. Wipe off
liquid from the seat immediately, let the seat dry naturally and then check the
SRS warning light as follows.
●If the SRS warning light illuminates, keep the seat dry 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’s seat and have
the system checked by your Toyota dealer.
● If the SRS warning light does not illuminate, check that the front passen-
ger’s frontal airbag ON and OFF indicators work properly. If the indicators
do not work properly, do not allow anyone to sit on the front passenger’s
seat and have the system checked by your Toyota dealer.

1-7. Safety information

Before driving
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.

■SRS warning light
If the warning light exhibits any of the following conditions, there may be a
malfunction in the seat belt pretensioners, SRS airbag system and/or front
passenger occupant classification system. Immediately take your vehicle to
your nearest Toyota dealer to have the system checked. Unless checked
and properly repaired, the seat belt pretensioners, SRS airbag and/or front
passenger occupant classification system will not operate properly in the
event of a collision, which may increase the risk of death or serious injury.
●Flashing or flickering of the warning light
● No illumination of the warning light when the engine switch is first turned to
the “ON” position.
● Continuous illumination of the warning light
● Illumination of the warning light while driving

1-7. Safety information
Front passenger occupant classification system
Your vehicle is equipped with a front passenger occupant classifica-
tion system. Using the sensors installed under the seat cover, the
system detects the conditions of the front passenger seat and acti-
vates or deactivates the frontal ai rbag for front passenger seat. The
occupant classification system may not inflate the front passenger’s
SRS frontal airbag even when the driver’s SRS frontal airbag
deploys. This is not a malfunction. If the seat belt buckle switch and/
or front passenger’s occupant classification system have failed, the
SRS warning light will illuminate. Have the system inspected by your
Toyota dealer immediately if the SRS warning light illuminates.
If your vehicle has sust ained impact, this may affect the proper func-
tion of the Toyota advanced frontal airbag system. Immediately con-
tact your Toyota dealer and have your vehicle inspected. Do not use
the front passenger seat while driv ing to your Toyota dealer.
