Failure to carry out service operations in the correct sequence could cause the SRS to unexpectedly deploy during servicing, possibly leading to a serious accident. Before servicing (including removal/installation, inspection and replacement of parts), be sure to read the precautionary notices for the supplemental restraint system (See page ). |
