Nissan Sentra Service Manual: Precaution for Seat Belt Service
CAUTION:
- Before removing the seat belt pre-tensioner assembly, turn the
ignition switch OFF, disconnect both
battery terminals and wait at least three minutes. For approximately three
minutes after the battery
terminals have been removed, it is still possible for the air bag and seat
belt pre-tensioner to deploy.
Therefore, do not attempt work on any SRS connectors or wires until at least three minutes have passed.
- After replacing or reinstalling seat belt pre-tensioner assembly or reconnecting seat belt pre-tensioner assembly connector, make sure entire SRS operates properly. Refer to SRC-41, "ADDITIONAL SERVICE WHEN REPLACING CONTROL UNIT : Special Repair Requirement".
- Do not disassemble buckle or seat belt assembly.
- Replace anchor bolts if they are deformed or worn out.
- Do not oil tongue or 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 NISSAN seat belt assembly.
