SRS AIRBAG SYSTEM


  1. General


    1. If the vehicle is rolling sideways, the RSCA (Roll Sensing Curtain Shield Airbags) helps to reduce the impact applied to the occupants by operating the seat belt pretensioners for the driver, front passenger and rear No. 1 seat outer passengers and the left and right curtain shield airbags.


      1. If the vehicle rolls over due to an incline, the 2 roll rate sensors built into the airbag sensor assembly detect the vehicle's roll angle and rotation speed.

      2. If the vehicle has rolled over due to a side collision, the side airbag sensor or rear airbag sensor detects the impact of the collision and deploys the front or rear seat side airbag and curtain shield airbag on the side which experienced the collision. By detecting the roll over using 2 roll rate sensors and deceleration sensor 1 which can detect lateral deceleration, the airbag sensor assembly activates the seat belt pretensioners for the driver, front passenger and rear No. 1 seat outer passengers and deploys the curtain shield airbag on the opposite side of the collision.

  2. RSCA OFF Switch


    1. In consideration of off-road driving, an RSCA OFF switch is used to enable the driver to cut off the RSCA control at will.


      1. If the RSCA OFF switch remains pressed for approximately 2 or more seconds, the airbag sensor assembly cuts off the operation of the RSCA.

      2. In the case of a side collision, the airbag sensor assembly will operate the curtain shield airbags regardless of whether the RSCA OFF switch is ON or OFF.
