NOTE:
There are two ways to stop the retractor from "free wheeling". One way is to "buckle up" and the retractor will lock immediately.
The second way is to pull approximately 12" of webbing from the lap belt retractor, wait approximately 15 seconds, and a
thermal timer will deactivate the "free wheeling" feature.
Webbing Cannot Be Fully Extracted From Lap Belt Retractor
1.
If the webbing cannot be pulled from the lap belt retractor, it may be twisted and jammed in a partially extended position. If the twist can be
removed without retractor disassembly, allow the webbing to fully retract and then withdraw a minimum of 18 inches (460mm) of webbing
from the retractor, return 2 inches (50mm) and check for lock-up. If OK, allow to retract fully and buckle up while sitting in the seat. Repeat
five times to ensure proper operation. Verify that belt webbing can be extended far enough to expose the manufacturer's certification label.
2.
If not OK, replace the seat belt assembly and repeat appropriate portions of Step 1, above.
