1. Preparation:
* Gather Tools: You'll likely need a set of trim removal tools (plastic pry tools are ideal to avoid scratching), possibly a ratchet and sockets (depending on whether any bolts are involved), and potentially a helper.
* Safety First: Park on a level surface, engage the parking brake, and disconnect the negative battery terminal to prevent accidental shorts.
2. Accessing the Seat:
* Headrests: Remove the headrests (usually by pulling up on a release lever or button at the base of each headrest).
* Seat Belts: Unlatch and detach the rear seat belts from their anchoring points, if necessary.
3. Removing the Seat:
* Backrest: The process for removing the backrest will vary. You might find:
* Release Levers/Buttons: Look closely along the bottom of the seatback (where it meets the seat cushion) for release levers or buttons. These often need to be pressed or pulled to release retaining clips or mechanisms.
* Bolts: In some cases, you may need to remove bolts securing the backrest to the seat frame. These are typically located under the seat cushion or along the bottom edge of the backrest itself.
* Cushion: Once the backrest is detached (if applicable), the seat cushion typically folds forward or lifts out, revealing any further fasteners (bolts or clips) holding it to the floor.
* Removal: Once all fasteners are removed, carefully lift and remove the seat cushion and backrest. They may be heavy, so have a helper if needed.
Important Considerations:
* Clips and Fasteners: Be very gentle when using trim removal tools to avoid breaking plastic clips. Take pictures as you disassemble to help with reassembly.
* Electrical Connections: There might be small electrical connectors for seat heaters or other options. Gently disconnect these if present.
* Weight: Rear seat sections can be heavy. Take precautions to avoid injury.
If you're unsure about any step, consult your Cadillac DTS owner's manual or seek professional help from a qualified mechanic or auto upholstery specialist. Attempting to remove the seat without proper understanding can lead to damage to your vehicle.
