CAUTION:
+Before removing the seat belt pre-tensioner assembly (if equipped), turn the ignition switch off,
disconnect both battery cables and wait at least 3 minutes.
+After replacing or reinstalling seat belt pre-tensioner assembly, or reconnecting seat belt pre-ten-
sioner connector, check the system function. Refer to ``SRS Operation Check'' (RS-30) for details.
+Do not disassemble buckle or seat belt assembly.
+Replace anchor bolts if they are deformed or worn out.
+Never oil tongue and buckle.
+If any component of seat belt assembly is questionable, do not repair. Replace the whole seat belt
assembly.
+If webbing is cut, frayed, or damaged, replace seat belt assembly.
+When replacing seat belt assembly, use a genuine seat belt assembly.
+After any collision, inspect all seat belt assemblies, including retractors and other attached hard-
wares (i.e., guide rail set).
