How to Remove Mercedes Back Seat: A Step-by-Step Guide

Removing the back seat of a Mercedes-Benz is a process that can often be tackled with a bit of automotive know-how and the right tools at hand.

Whether you’re looking to make a repair, clean thoroughly, install new seat covers, or gain better access to interior components, taking out the rear seat can be quite advantageous. It can enhance the space for carrying cargo, make cleaning more efficient, and allow for more significant modifications or customizations to your vehicle’s interior.

We understand that your time is valuable; therefore, we’ve streamlined the process to make it as efficient as possible, minimizing the time your project takes from start to finish.

By using the appropriate tools and methods, you’ll find that the performance gain in accessing and maintaining the space beneath or behind the rear seats can be substantial. Moreover, this task can be accomplished by most DIY enthusiasts and is a great starting point for those new to car modifications, often requiring only basic tools like a wrench and a plastic pry tool.

Preparing for Seat Removal

Before we dive into the task of removing the rear seats from a Mercedes, it’s crucial to have all the necessary tools at hand and understand the scope of the project.

Removing the rear seats is a manageable task, but it does require attention to detail and the right equipment.

Gathering Necessary Tools

Tools Required:
  • Wrench set
  • Trim removal tool
  • Torx drivers or Allen keys, depending on the model
  • Socket set
  • Extension bars for reaching recessed bolts
  • Screwdrivers (flat-head and Phillips)

Gathering the right tools is the first step to ensure that the process goes smoothly.

A wrench set and trim removal tool are essential components. Different Mercedes models may require different tools like Torx drivers or Allen keys.

Having a complete socket set, along with extension bars, will help you reach any recessed bolts without straining. Ensure you also have both flat-head and Phillips screwdrivers.

Understanding the Project Scope

Understanding what removing the rear seats entails will help us avoid surprises during the process.

We’ll need to be mindful of the seat’s power connection if it’s equipped with electric seat features. It’s not just a matter of using brute force; it involves precision and a bit of finesse.

Always disconnect any power connections before starting to ensure a safe working environment.

We’re not just pulling out a couple of bolts; we may encounter a complex array of fasteners and retaining clips that secure the seats in place. Also, if our project car has front seats that are obstructive, we might need to adjust or temporarily remove them to create enough space to work.

Removal Process for Rear Seats

When removing the rear seats from a Mercedes, it’s essential to have a clear outline of the steps involved. From detaching the cushions to accessing seat belts, each stage requires specific actions to ensure a safe and efficient removal process.

Detaching the Rear Seat Cushions

First, fold down the rear headrests if applicable.

We locate the locking tabs for the rear seat cushion underneath the front of the seat. Upon finding these, we disengage them by pulling them toward us, which will free the cushions for removal.

Unbolting the Backrest and Headrests

The removal of the rear backrest generally involves the loosening of bolts securing it to the car’s frame.

Typically, we would find three 10mm bolts, one in the middle and one at each end of the backrest.

Once the bolts are removed, we push the backrest and slide it upward to release it from its final holding points. Careful attention is given to the headrests, as they may have their own securing mechanisms.

Accessing and Removing Seat Belts

To fully remove the back seat, it’s necessary to access the points where the seat belts are bolted to the car.

Underneath the rear seat cushions or behind the backrest, depending on model, we would find bolted attachments usually secured by T45 Torx bolts or similar.

We remove these bolts, making sure to keep track of all attachments and components for reinstallation later.

It’s also vital to handle the seat belt mechanisms delicately to avoid impairing their functionality.

Throughout the removal process, we maintain an organized approach by keeping screws, bolts, nuts, and removed components in a safe and labeled manner.

This systematic method aids in preventing any loss of parts and in ensuring a smooth reassembly process.

Interior and Seat Components

When removing the rear seats in a Mercedes, we gain access not only to the car’s interior base but also the components beneath the seats. This process allows us to thoroughly vacuum and clean, or service switches and wiring without obstruction.

Vacuuming and Cleaning Beneath the Seats

Removing the back seats of your Mercedes opens up a significant area for cleaning.

Access to the space beneath the seats enables an in-depth clean of the carpets and interior. Here’s our approach:

  1. Using a vacuum, we meticulously remove debris and dirt from the exposed carpet.
  2. We then proceed with spot-cleaning any stains on the carpet or adjacent interior surfaces.

It’s crucial not to overlook the gaps between the seats and the console, often collecting dust and small particles.

Servicing Seat Switches and Wiring

The removal of rear seats also exposes the electrical components, such as seat switches and wiring. It’s our chance to inspect and service these parts.

Always disconnect the battery before handling electrical components to avoid any short circuits or electrical shocks.

We follow these steps:

  • Carefully inspect the wiring and connectors for any signs of wear or damage.
  • If necessary, we replace or repair any faulty parts to ensure all seat functions operate correctly.

This also provides an opportunity to check the connections and wiring leading to the trunk and other adjacent areas, ensuring everything is in working order.

Reinstallation and Finishing Touches

After successfully removing the rear seats from your Mercedes-Benz, it’s essential for us to ensure that reinstallation is performed with precision. Meticulously securing each component ensures a solid fit and safe operation thereafter.

Securing Seats and Components

We begin by carefully aligning the rear bench seat with the corresponding hooks on the floor of the car.

Using a new thread, if available, will minimize the possibility of stripping old threads, helping us avoid any unnecessary delays.

For fastening, we’ll need the appropriate sockets and fasteners specific to the Mercedes model.

It’s crucial to:
  • Tighten all bolts to the manufacturer’s specified torque.
  • Ensure that the flat rear bench seat is secure and snapped into its proper place.

Alignment of seat switches and the use of a flathead screwdriver may be required for some models, particularly the Mercedes C-Class, to effectively reconnect and secure the seat’s components.

Final Inspection and Test

A thorough inspection ensures that all components are correctly installed. This includes visually checking that no tools are left under the seats or within the fastening components.

Giving the newly installed seats a firm shake can verify stability.

We also make sure the seat switches are fully operational and the seat moves as intended.

If you have documented your project with photos, comparing your final installation with the project photos can be a final step to ensure every component looks as it should.

If everything checks out, our last step is to take a test drive—listening for any unusual movements or noises—confirming the job was done correctly.
