FRONT SEAT BELT REMOVAL/INSTALLATION [STANDARD DEPLOYMENT CONTROL SYSTEM]

WARNINGHandling the front seat belt (pre-tensioner seat belt) improperly can accidentally deploy the pre-tensioner seat belt, which may seriously injure you. Read the air bag system service warnings and cautions before handling the front seat belt. (See AIR BAG SYSTEM SERVICE WARNINGS .) (See AIR BAG SYSTEM SERVICE CAUTIONS .)
WARNINGThe side air bag sensor is attached to the lower part of the B-pillar. When working around the B-pillar, disconnect the negative battery cable avoiding excessive impact to the lower part of the B-pillar.
CAUTIONThe ELR (emergency locking retractor) has a spring that will unwind if the retractor cover is removed. The spring cannot be rewound by hand. If this occurs, the ELR will not work properly. Therefore, do not disassemble the retractor.
