WARNING:
The following procedure prescribes critical repair steps required for correct restraint system operation during a crash. Follow all notes and steps carefully. Failure to follow step instructions may result in incorrect operation of the restraint system and increases the risk of serious personal injury or death in a crash.
NOTE:
To prevent system failure, carry out the OCS reset when a front passenger seat cushion is disassembled, a new trim cover is installed or an OCS service kit is installed. Use a diagnostic scan tool to carry out the OCS reset command.
NOTE:
The cushion heater mat on a front outboard passenger seat is not serviced separately. If a new cushion heater mat is needed on the front passenger seat, install an OCS service kit equipped with a heater mat. Failure to follow this instruction may result in incorrect operation of the OCS.

The OCS components (seat cushion foam, heater mat (if equipped) and OCS) are calibrated to each other and are serviced as an assembly. The OCS components are not to be installed separately. If a new OCS, seat cushion foam or heater mat (if equipped) are needed, a new OCS service kit must be installed.
