1. Check for twisted web in front and rear windows of the housing.

2. To clear a twist, push or pull the web to loosen it on the retractor spool.

3. Side to side movement of the belt may also clear partial twist in the web.

For Reverse Lock:

1. Check for reverse lock.

2. Mount the belt in the seat belt housing.

3. Pull the web forcefully to tighten it on the retractor spool, which allows more web to be wrapped on spool when it retracts.

4. Slowly allow the web to retract back into the retractor housing.
