The rear bench seat in the Mercedes-Benz G-Class W465 (2001–2018) is an integral part of the vehicle's interior, providing seating for rear passengers while also playing a role in the cargo space configuration of the vehicle. While the G-Class is primarily known for its off-road capabilities and rugged build, its interior is designed for both comfort and utility, and the rear bench seat contributes significantly to both.

Overview of the Rear Bench Seat in the G-Class W465

• Seating Capacity: The G-Class W465 typically accommodates two or three passengers in the rear bench, depending on the configuration. In some models, the split-folding rear seat feature allows for flexibility in seating and cargo space.
• Position and Design: The rear bench seat is located at the back of the cabin, facing forward. It's designed to offer comfort and support for rear passengers during long journeys or off-road expeditions. The seat is generally upholstered in materials that match the overall interior, such as leather or premium fabric.

Features of the Rear Bench Seat

1. Adjustable Backrests:
   • Depending on the specific model and trim level, the rear bench seat may feature adjustable backrests that can be reclined to provide more comfort to passengers. This can be especially useful for long trips.
2. Split-Folding Design:
   • Many G-Class models have a split-folding rear bench seat, which means each side of the bench can be folded down independently to increase the cargo area. This is useful for transporting larger items when the rear seats are not needed for passengers.
3. Seatbelts:
   • The rear bench seat is equipped with seat belts for all passengers, ensuring that they are secured during driving. These are typically three-point seatbelts for safety.
4. Storage and Utility:
   • Some versions of the rear bench seat feature storage compartments underneath or behind the seat. These compartments can be used to store tools, emergency equipment, or personal items. This is particularly useful in the G-Class, which is often used for off-road driving where extra gear is necessary.
5. Heated and Powered Options:
   • On higher-end models or in some optional packages, the rear bench seat may have heating elements for comfort in cold weather. Additionally, some versions of the G-Class may feature power-adjustable rear seats for increased comfort and convenience.

Common Issues with the Rear Bench Seat

The rear bench seat in the G-Class W465, like any component of a luxury vehicle, can encounter issues due to wear and tear or misuse. Some common problems include:

1. Seatback Latch Failure:
   • If the latch or locking mechanism that keeps the seatback in an upright position fails, the seat may not lock properly and could move or rattle during driving.
2. Stiff or Jammed Reclining Mechanism:
   • If the seat has a reclining function, the mechanism could become stiff, jammed, or fail entirely due to dirt, rust, or mechanical issues.
3. Seat Upholstery Damage:
   • The upholstery on the rear bench seat can suffer from tearing, scratches, or fading, especially if the vehicle is frequently used in off-road conditions or if passengers wear rough clothing (e.g., outdoor gear).
4. Broken Seatbelt Mechanism:
   • Seatbelts can occasionally fail to retract properly or can become tangled, preventing them from functioning as they should. Regular inspection and cleaning can help maintain their proper function.
5. Difficulty Folding the Seat:
   • If the rear bench seat is a split-folding model, the folding mechanism might become difficult to operate over time. This could be caused by dirt, rust, or mechanical failure of the release latches.

How to Maintain the Rear Bench Seat

1. Regular Cleaning:
   • Keep the upholstery clean by vacuuming and using appropriate cleaners for leather, fabric, or vinyl, depending on your seat material. This prevents dirt buildup that can lead to wear over time.
2. Check the Folding Mechanism:
   • If the rear seat has a folding mechanism, check periodically for smooth operation. Ensure that the latch and release handle are functioning properly and that there are no obstructions.
3. Lubricate Moving Parts:
   • Apply a silicone-based lubricant to the seat adjustment mechanisms (such as recliners or folding parts) to keep them operating smoothly and to avoid stiffness or jamming.
4. Inspect Seatbelts:
   • Regularly check that the seatbelts in the rear are not frayed or damaged. Make sure they retract smoothly and lock into place when extended.
5. Protect from Wear and Tear:
   • Consider using seat covers to protect the upholstery from excessive wear, especially if you frequently transport heavy items or have pets that travel with you.

How to Fold the Rear Bench Seat (If Applicable)

For G-Class models equipped with a split-folding rear bench seat, folding the seat can be done in the following general steps:

1. Locate the Release Mechanism:
   • The release lever or handle for the rear seatback latch is typically located near the top of the seat or in the middle section of the rear seat. In some models, the release mechanism may be a handle on the seat itself, while in others, it may be a button or lever on the seat's base.
2. Pull the Release Lever:
   • To fold the seat, pull the release lever or button, which will release the seatback from its locked position.
3. Fold the Seatback Forward:
   • After releasing the latch, carefully fold the seatback forward to increase the cargo space. In some models, you may need to push the seat forward manually to fully lock it into the folded position.
4. Ensure the Seat Locks Back into Place:
   • When you’re ready to return the rear seat to the upright position, simply pull the seatback back up and ensure the latch clicks into place. This locks the seat back into its secure position.

Replacing the Rear Bench Seat

If the rear bench seat has suffered from damage (e.g., broken frame, torn upholstery, faulty latch mechanisms), replacing the seat can be done by following these steps:

1. Remove the Seat from the Vehicle:
   • Depending on the design, you may need to remove bolts or screws securing the seat to the floor. Disconnect any electrical connectors, such as those for seat heating or power adjustments (if applicable).
2. Replace the Seatback Mechanism:
   • If the issue is with the reclining or folding mechanism, you may need to replace the locking mechanism, latch, or the entire frame if it's broken.
3. Install the New Rear Bench Seat:
   • Once the old seat is removed, install the replacement seat by reversing the removal process. Make sure it’s securely bolted to the floor and connected properly if there are electrical systems involved.
4. Test the Seat:
   • After installing the replacement seat, test the seat’s folding mechanism, reclining function, and seatbelt operation to ensure everything works properly.

Summary

The rear bench seat in the G-Class W465 is a key part of the vehicle’s interior, offering rear passenger seating and flexibility for additional cargo space. The split-folding design in many models allows for increased utility, while features like seat heaters and adjustable recliners provide comfort. Regular maintenance of the seat’s mechanisms and upholstery ensures the rear bench remains functional, clean, and comfortable.
