Removal and Installation

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 injuring the event of an accidental deployment.
- To reduce the risk of personal injury, do not use any memory saver devices.

NOTE:
- If a seat equipped with a SRS component is being serviced, the SRS must be depowered.
- The air bag warning lamp illuminates when the restraints control module (RCM) fuse is removed and the ignition switch is ON. This is normal operation and does not indicates SRS fault.
- The SRS must be fully operational and free of faults before releasing the vehicle to the customer.
- The backrest thermo-electric device (TED) filter is detachable from the TED assembly housing and can be replaced without TED removal.
