Seat Belt Does Not Roll Up Correctly

If you receive customer reports in the above model vehicles of the front or rear seat belts not rolling up fully, the cause could be dirt deposits on the seat
belt guide due to a soiled seat belt. Cleaning the belt guide and seat belt should restore proper function of the seat belt retraction. 

To resolve, perform the following.

1. Clean the belt guide using MB Plastic Cleaner (Figures 1 and 2).
