    Precautions for SRS “AIR BAG” and “SEAT BELT PRE-TENSIONER” Service

    • Never probe the electrical connectors on air bag, side air curtain modules or seat belts.
    • Never disassemble or tamper with safety belt buckle/retractor pretensioners, adaptive load limiting retractors, safety belt inflators, or probe the electrical connectors.
    • Do not use electrical test equipment to check SRS circuits unless instructed to in this Service Manual.
    • Before servicing the SRS, turn ignition switch OFF, disconnect both battery cables and wait at least 3 minutes. For approximately 3 minutes after the cables are removed, it is still possible for the air bag and seat belt pre-tensioner to deploy. Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
    Failure to follow this instruction may result in the accidental deployment of these modules, which increases the risk of serious personal injury or death.
