System Description

  1. GENERAL 
    1. Airbag for Frontal Collision
      1. The dual-stage SRS driver and front passenger airbags deploy simultaneously in the event of a frontal impact collision as supplements to the seat belts. The dual-stage SRS airbag system controls the airbag inflation output by judging the extent of the impact, the seat position and whether the seat belt is fastened.
