CAUTION:
  • Before handling the airbag system components, refer to "CAUTION" of "General Description" in "AIRBAG SYSTEM". Ref. to AIRBAG SYSTEM>GENERAL DESCRIPTION>CAUTION .
  • Side impact sensor (under the rear center seat) for the airbag system is located under the front center of the rear seat cushion. Be careful not to apply strong impact to the sensor when working with the rear seat cushion removed.
  • Before discarding a pretensioner, always perform an activation process to prevent any false activation.
  • Wear protective gloves, safety goggles and earplugs during this operation. Wash your hands afterwards.
