1.HANDLING PRECAUTIONS FOR SRS AIRBAG SYSTEM

  1. The vehicle is equipped with an SRS (Supplemental Restraint System) such as airbags. Failure to carry out service operations in the correct sequence could cause the SRS to unexpectedly deploy during servicing. This may cause a serious accident.
    Before servicing (including inspection, replacement, removal and installation of parts), be sure to read the precautionary notices for the Supplemental Restraint System (Click here).
