Functional Inspection

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2004 Porsche Boxster, 2003 Porsche Boxster, 2002 Porsche Boxster, 2001 Porsche Boxster, and 2000 Porsche Boxster. However, it is still accessible from the selected car via links, so may be relevant.

It must be possible to unroll the belt strap smoothly from the belt retractor via the deflector fitting by pulling evenly, and the tongue of the seat belt must engage audibly in the buckle.
An abrupt pull on the belt strap must lock the belt retractor.
