Seat Cushion Heater Mat: Removal

NOTE: The passenger seat is equipped with an OCS bladder system, to prevent system failure, it is necessary to carry out the OCS reset when a front passenger seat cushion is disassembled, a new cushion cover is installed or an OCS service kit is installed. A scan tool is used to carry out the OCS reset.

NOTE: Do not reinstall any heater mat after removal. The adhesive will not adhere correctly, causing it to bunch up or shift out of place. A new heater mat and a new foam pad must be installed. If a new heater mat is needed for a passenger seat cushion, an OCS service kit must be installed. Failure to follow these instructions can result in heated seat component damage, system failure or incorrect OCS operation.
