The noise that occurs when the belt is reeling in is normal. If the noise is excessive, the belt must be replaced. Never use oil or grease to eliminate the noise. For safety reasons, the belt reeling and tensioning machine must not be disassembled.
1. Pull the seat belt out completely and check the webbing for damaged threads. If there are any frayed threads without any separation of the fibers, the belt should not be replaced.
2. Damage may be caused by, for example, a pinched belt or exposure to a burning cigarette. In this case, the belt should be replaced.
3. If there is wear and tear without signs of damage to the threads, there is no need to replace the belt.
4. A belt that is difficult to move should be checked for twists. If necessary, remove the trim on the central pillar.
5. If the automatic rewinder does not work, the belt must be replaced (work of the service station).
6. The belt webbing should only be cleaned with soap and water. Never use solvents or chemical cleaners.
