Front Seat Backrest: Disassembly
WARNING:
Always wear safety glasses when repairing an air bag supplemental restraint system (SRS) vehicle and when handling an air bag module. This will reduce the risk of injury in the event of an accidental deployment.
WARNING:
Carry a live side air bag module with the air bag and tear seam pointed away from your body. This will reduce the risk of injury in the event of an accidental deployment.
WARNING:
Do not set a live side air bag module down on the cover tear seam. This will reduce the risk of injury in the event of an accidental deployment.
WARNING:
After deployment, the air bag surface can contain deposits of sodium hydroxide, a product of the gas generant combustion that is irritating to the skin. Wash your hands with soap and water afterwards.
WARNING:
Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury.
WARNING:
Before installing the side air bag module, check it for damage and foreign objects. If the air bag module is damaged, replace it. If any foreign objects are found, remove them. Failure to do so can result in personal injury in the event of an air bag deployment.
WARNING:
Vehicle sensor orientation is critical for correct system operation. If a vehicle equipped with an air bag supplemental restraint system (SRS) is involved in a collision, inspect the sensor mounting bracket and wiring pigtail for deformation. Replace and correctly position the sensor or any other damaged supplemental restraint system (SRS) components whether or not the air bag is deployed.
CAUTION:
When removing the seat backrest trim panel, be careful not to damage the J-hooks. If the J-hooks are damaged, the seat backrest trim panel must be replaced.
NOTE:
Front seat backrest trim covers installed on seats with side air bags cannot be repaired. The front seat backrest trim covers are to be installed new. Cleaning is permissible.
NOTE:
If a side air bag deployment took place, a new seat back pad, trim cover and side air bag module must be installed. Install a new seat back frame only if necessary.
