For 1990-2009 cars only
  1. Loosen the bracket set screw.
  2. Grasp the spotlamp.
  3. Slowly rotate the spotlamp inboard to the point where the shaft contacts the parkstop.

  4. Slowly rotate the spotlamp outboard to a position 5 degrees past vertical in order to accomplish the following results:
  5. • The backstop is in motion.
    • The outer tube shaft rotates.
  6. Tighten the bracket set screw enough in order to prevent the shaft tube from rotating while the stoplamp moves between stop positions.
  7. Rotate the spotlamp head inboard in order to position the parkstop.
  8. This prevents the stoplamp from making contact with the body components.

  9. Position the parkstop of the shaft in order to accomplish the following results:
  10. • Rotation of the spotlamp on the axis
    • Clearance of the spotlamp from the nearest body components by 0.5-13.0 mm (0.02-0.50 in)
  11. Tighten the bracket set screw in order to prevent rotation of the spotlamp shaft.
  12. Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. 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.

  13. Adjust the spotlamp head clamping screw in order to accomplish the following results:
  14. • The spotlamp rotates easily on the shaft.
    • The spotlamp head clamping screw holds the spotlamp in any adjusted position between the parkstop and the backstop.
    • The total range of motion of the spotlamp head is approximately 90 degrees.

    Tighten
    Tighten the head clamping screw to 3 N·m (27 lb in).
