Caution: When you are performing service on or near the SIR components or the SIR wiring, you must disable the SIR system. Refer to Disabling the SIR System. Failure to follow the correct procedure could cause air bag deployment, personal injury, or unnecessary SIR system repairs.

Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure.
