front passenger airbag, etc. 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 or installation of parts, inspection or replacement), be sure to
read the precautionary notice for the supplemental restraint system (see PRECAUTION
