CAUTION:
• After any collision, inspect all seat belt assemblies, including retractors and other attached compo-
nents, such as the guide rail set. NISSAN recommends replacing all seat belt assemblies in use dur-
ing a collision, unless they are not damaged and are inspected to confirm they are operating
properly after a minor collision.
Also inspect all seat belt assemblies that are not in use during a collision, and replace any compo-
nents if damaged or not operating properly. The 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 have
been deployed.
• If any component of the seat belt assembly is suspected of being damaged or not operating prop-
erly, do not repair the component. Replace the components as an assembly.
• If the seat belt webbing is cut, frayed, or damaged then replace the seat belt assembly.
• Never lubricate the seat belt buckle or tongue.
• When replacing any seat belt assembly always use a Genuine NISSAN seat belt assembly.
