What is the reason why the leg rest of the Mercedes-Benz driver's seat cannot be fully raised?
2 Answers
Mercedes-Benz driver's seat leg rest cannot be fully raised possibly due to the adjustment knob or severe wear of the mechanical lifter gears. This can be repaired or replaced at a decoration shop. Advantages of the leg rest: Thanks to the additional front, rear, and height adjustments, the front passenger seat can be further moved forward to the so-called legroom expansion position. This provides ample space for rear passengers, making the journey more comfortable. The significantly increased legroom allows rear passengers to adopt a more comfortable sitting posture. Use of the leg rest: The leg rest has also been extended to car seats, mainly used to assist in increasing the leg support area for passengers to improve riding comfort. The seat leg rest adjustment can adjust the angle to support the lower leg, divided into front seat and rear seat leg rest adjustments; The leg rest adjustment first appeared in luxury sedans, providing a relaxed sitting posture for rear bosses, and later developed in MPV models accordingly.
I've fixed many Mercedes seat leg rest issues. The driver's side leg rest not lifting fully is often due to mechanical jamming, like deformed rails or small objects stuck inside. For electric versions, it might be insufficient motor torque causing it to stop when encountering resistance. Another possibility is rusted pivot shafts on the leg rest brackets, common in humid regions. Some owners overlook incorrect seat memory settings. One case I encountered involved floor mats pressing on wiring under the seat, disrupting signals. If this occurs in new cars, it's likely assembly defects; for older vehicles, it's usually wear and tear. Don't force it - the aluminum rails are brittle. Have a professional disassemble it for inspection and replace rails if necessary.
