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:

   ā€¢ 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.
   ā€¢ Keep sharp edges and damaging objects away from belts.
   ā€¢ Avoid bending or damaging any portion of the belt buckle or latch plate.
   ā€¢ Do not bleach or dye belt or strap webbing. Clean with a mild soap solution and water.
   ā€¢ When installing lap or shoulder belt anchor bolts, start the bolts by hand to ensure that the bolts are threaded straight.
   ā€¢ Do not attempt repairs on lap or shoulder belt retractor mechanisms to lap belt retractor covers. Replace defective assemblies with new service replacement parts.
   ā€¢ 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.
