Key functional features of this component include:

• Post-accident repairs – when the seat belt needs replacement after the safety system has deployed.
• Addressing wear and tear issues – such as mechanical wear, belt damage, or problems with the retractor mechanism.
• Restoring the vehicle to factory condition – in cases of previous, non-original safety system modifications.

Using an original seat belt helps maintain consistency with factory service documentation and repair procedures for the Mercedes Vito W639.
