ATTENTION:
HSV vehicles are equipped with a Supplemental Restraint System (SRS). An SRS consists of seat belt pre-
tensioners (fitted to all front se ats), a dri ver’s-side air b ag, a p asseng er’s-side air b ag and left and right han d side
air bags. Refer to CAUTIONS, Section 12M Occupant Protection System in the MY 2005 VZ Series Service
Information or Section 12M Occupant Protection System in the MY 2005 WL Series Service Information before
performing any service operation on or around SRS components, the steering mechanism or wiring. Failure to
follow the CAUTIONS could result in personal injury or unnecessary SRS s ystem repairs.
