HANDLING PRECAUTIONS ON SRS AIRBAG SYSTEM

Failure to carry out service operation in correct sequence could cause the SRS to unexpectedly deploy during servicing, possibly leading to a serious accident. Before servicing (including removal or installation of parts, inspection or replacement), be sure to read the precautionary notice for the supplemental restraint system (See AIR BAG SAFETY PRECAUTIONS ).
