SRS Airbag( Supplemental Restraint System Airbag)
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 is active only when the ignition switch is in the“ ON” position.
. SRS front seat side airbag( driver’ s side)
. SRS front seat side airbag( passenger’ s side)
. SRS rear seat side airbag( right-hand side)
. SRS rear seat side airbag( left-hand side)
. 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” FP85. 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” FP83.
! After deployment s01ah0304
After the deployment, the SRS front seat side airbag and SRS rear seat side airbag immediately start to deflate.
The SRS curtain airbag remains inflated for a while following deployment then slowly deflates.
The SRS front seat side airbag, SRS rear seat 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 front seat side airbag, SRS rear seat 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 front seat 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 front seat side airbag, SRS rear seat 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 front seat side airbag, SRS rear
