1-7. Safety information
BRZ_U (A4450BE-A)
■ Operation
The SRS side airbag and SRS curtain airbag can function only when the
ignition switch is in the “ON” position.
The driver’s and front passenger’s SRS side airbags and SRS curtain air-
bags deploy independently of each other since each has its own impact sen-
sor. Therefore, they may not both deploy in the same accident. Also, the
SRS side airbag and SRS curtain 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 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 airbag on the impacted side to inflate.
If the rollover sensor detects rollover of the vehicle, the control module
inflates the SRS curtain airbags. At this time, the driver’s and front passen-
ger’s seatbelt pretensioners also operate at the same time.
