Disassembly

WARNING:
- Always wear safety glasses when repairing an air bag supplemental restraint system (SRS) vehicle and when handling an airbag module. This will reduce the risk of injury in the event of an accidental deployment.
- 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.
- 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.
- 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.
- Never probe the connectors on the air bag module. Doing so can result in air bag deployment, which can result in personal injury.
- Side air bag modules with damaged covers must be replaced.
- Front seat back trim covers installed on seats equipped with side air bags cannot be repaired; they are to be replaced (cleaning is permissible).
- To reduce the risk of personal injury, do not use any memory saver devices.

NOTE:
- If a side air bag deployment took place a new backrest foam pad, trim cover, side air bag module, bracket and nuts, U-nuts and bolts must be installed. The seat back frame should be replaced if necessary.
- If a seat equipped with a supplemental restraint system (SRS) component is being serviced, the supplemental restraint system (SRS) must be depowered.
- The air bag warning lamp illuminates when the RCM fuse is removed and the ignition switch is ON. This is normal operation and does not indicate a supplemental restraint system (SRS) fault.
- The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
