Removal Procedure

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.

Notice: To prevent possible seat belt damage, refer to the following items before servicing or replacing lap and shoulder belts, including single loop belt systems:

   • Lap and shoulder belts will be serviced as follows:
      - Replace only the part in question.
      - Do not intermix standard and deluxe belts on front or rear seats.
      - All attachment hardware must be replaced, not reused.
   • Keep sharp edges and damaging objects away from belts.
   • Avoid bending or damaging any portion of the belt buckle or latch plate.
   • Do not bleach or dye belt or strap webbing. Clean with a mild soap solution and water.
   • When installing lap or shoulder belt anchor bolts, start the bolts by hand to ensure that the bolts are threaded straight.
   • Do not attempt repairs on lap or shoulder belt retractor mechanisms to lap belt retractor covers. Replace defective assemblies with new service replacement parts.
   • Do not attempt to remove the seat belt retractor cover. The cover and the long rivet securing the cover to the retractor are not available as service replacement parts.

Installation Procedure

  1. Install the lap retractor over the stud. Align the tab on the retractor with the notch in the seat frame.

Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
