How can I remove the rear seat from my 2012 E-350 Mercedes Benz?

Removing the middle seats from a R350 Mercedes Benz 4matic can vary depending on the model year and specific configuration of your vehicle. Here are some general steps on how to remove the middle seats from an R350 Mercedes Benz 4matic:

1. Begin by locating the seat release lever or button. This will typically be located on the bottom of the seat, near the floor.
2. Press the seat release lever or button and then pull the seat forward. This will release the seat from its locked position.
3. Once the seat is released, you will need to remove the seat belt from the seat. This is typically done by pressing a button or lever on the seat belt retractor and then pulling the seat belt out of the seat.
4. After the seat belt is removed, you can lift the seat out of the vehicle.
5. To remove the back seat, you will need to locate the release lever or button on the seat back. This will typically be located near the top of the seat back, on the side that faces the rear of the vehicle.
6. Press the release lever or button and then pull the seat back forward. This will release the seat back from its locked position.
7. Once the seat back is released, you can lift it out of the vehicle.

Keep in mind that the specific steps may vary depending on the model year and configuration of your R350 Mercedes Benz 4matic. It is recommended to consult the owner's manual for your specific vehicle for more detailed instructions, or contact a professional technician for assistance.

It is located under the passenger seat. May have to loosen the pass front seat mounting screws and remove the two rear screws and lift the seat up at the rear about 3 inches to replace it.

You will need to remove the rear seats to access the hole just above the shock. Remove the bottom seat cushion first, then find the small bolts that hold the upper seat to the frame. Once removed, you will see access to the top of the shocks (might have a plastic covering the hole).
