Seat Backrest — Front

Disassembly

 WARNING: Always carry a live airbag with the deployment door, trim cover or tear seam pointed away from the body. Do not place a live airbag down with the deployment door, trim cover or tear seam facing down. Failure to follow these instructions may result in serious personal injury in the event of an accidental deployment.

NOTICE: Do not reinstall any heater mat or foam pad after removal. The adhesive will not adhere correctly to the foam pad, causing it to bunch up or shift out of place. A new heater mat and a new foam pad must be installed. Failure to follow these instructions can result in heated seat component damage and system failure.

NOTE: If a side air bag deployment took place, install a new seat backrest foam pad, cover, side air bag module, nuts and seat backrest frame (if necessary).

NOTE: For parts identification and location, refer to Seat — Exploded View, Front in this section.
