SRS airbag ( Supplemental Restraint System airbag )
! SRS curtain airbag
S01AH0303
Your vehicle is equipped with a SUBARU SRS curtain airbag system that complies with the Federal Motor Vehicle Safety Standard ( FMVSS ) No . 226 .
The SRS curtain airbag on each side of the cabin is stored in the roof side ( between the front pillar and a point over the rear seat ). An “ SRS AIRBAG ” mark is located at the top of each center pillar .
In a moderate to severe side impact collision , the SRS curtain airbag on the impacted side of the vehicle deploys between the occupant and the side window and supplements the seatbelt by reducing the impact on the occupant ’ s head .
In a rollover , SRS curtain airbags on both sides of the vehicle deploy between the occupant and the side window and supplement the seatbelt by reducing the impact to the occupant ’ s head .
In an offset frontal collision , SRS curtain airbags on both sides of the vehicle deploy between the occupant and the side window and supplement the seatbelt by reducing the impact to the occupant ’ s head and chest .
! Operation
S01AH0301
The following SRS airbags are active only when the ignition switch is in the “ ON ” position .
. Driver ’ s SRS side airbag . Front passenger ’ s SRS side airbag . SRS curtain airbag ( right-hand side ) . SRS curtain airbag ( left-hand side )
When the following sensors detect a certain amount of impact to the side of the vehicle or detect that the vehicle is leaning , airbag control units send signals to the airbag control modules to deploy the airbags .
. The side impact sensors
. The impact sensor in the airbag control module
. The rollover sensor in the airbag control module
SRS airbags are controlled by their airbag control units and deploy as necessary to effectively protect passengers depending on the accident type . Therefore , these airbags may deploy simultaneously .
For the locations of the sensors and control modules , refer to “ Components ” FP90 .
! After deployment
S01AH0304
After the deployment , the SRS side airbag immediately starts to deflate . The time required from detection of an impact to deflation of an SRS side airbag after deployment is shorter than the blink of an eye .
The SRS curtain airbag remains inflated for a while following deployment then slowly deflates .
The SRS side airbag and SRS curtain airbag deploy even when no one occupies the seat on the side on which an impact is applied .
When the SRS side airbag and SRS curtain airbag deploy , 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 .
CAUTION
Do not touch the SRS side airbag system components around the front seat seatback with bare hands right after deployment . Doing so can cause burns because the components can be very hot as a result of deployment .
