1-7. Safety information ■ 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 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 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 sensor, 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 curtain 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 passenger’s seatbelt pretensioners also operate at the same time. 114
