Seat Belt, Buckles, Retractors, Anchors And Adjusters: Inspection

WARNING: This page is about a different car, the 2019 Infiniti QX60. However, it is still accessible from the selected car via links, so may be relevant.

For details, refer to Diagnosis Procedure in SB service information.

Check anchors for loose mounting.
Check belts for damage.
Check retractor for smooth operation.
Check function of buckles and tongues when buckled and released.

CAUTION:

After any collision, inspect all seat belt assemblies, including retractors and other attached hardware (i.e., anchor bolt, guide rail set). INFINITI recommends replacing all seat belt assemblies in use during a collision, unless not damaged and properly operating after minor collision.
Also inspect seat belt assemblies not in use during a collision and replace if damaged or improperly operating.

Seat belt pre-tensioner should be replaced even if the seat belts are not in use during a frontal collision where the driver and passenger air bags are deployed.
If any component of seat belt assembly is questionable, do not repair.
Replace as seat belt assembly.
If webbing is cut, frayed, or damaged, replace belt assembly.
Do not oil tongue and buckle.
Use a genuine INFINITI seat belt assembly.
