SRS Airbag ( Supplemental Restraint System Airbag )
! Operation s01ah0301
The following SRS airbags is 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
Some of the airbags will deploy in a frontal collision . For details , refer to “ SUBARU Advanced Frontal Airbag System ” FP81 . 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 ” FP79 .
! After deployment s01ah0304
After the deployment , the SRS side airbag immediately starts to deflate .
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 .
After deployment , do not touch any part of the SRS curtain airbag system ( from the front pillar to the part of the roof side over the rear seat ). Doing so can cause burns because the components can be very hot as a result of deployment .
! Example of the type of accident s01ah0305
The SRS side airbag and SRS curtain airbag are designed as follows :
. To deploy in the event of an accident involving a moderate to severe side impact collision
. To function on a one-time-only basis
The SRS side airbag and SRS curtain airbag are not designed to deploy in the following cases :
. In most lesser side impacts
. In most frontal or most rear impacts ( because the SRS side airbag and SRS curtain airbag deployment would not protect the occupant in those situations )
The SRS curtain airbags are also designed to deploy when the vehicle is in an extremely inclined state such as during a rollover . They are not designed to deploy in most lesser inclined state .
