3. Verify that the seat belt locks when braking firmly.
4. If the belt does not lock, proceed with steps 5 through 8.
5. Remove seat belt retractor assembly.
6. Tilt the seat belt retractor slowly.
7. Check that the seat belt webbing can be pulled from the retractor at an inclination of 15 degrees or less and cannot be pulled from the retractor at an inclination of 45 degrees or more.
8. If the seat belt retractor does not operate as described, replace the retractor assembly.
