Understanding TPMS in Mercedes-Benz S Class

Before diving into the reset and relearn procedures, it’s important to understand what TPMS is and why it’s crucial for your Mercedes-Benz S Class.<>

What is TPMS?

TPMS is a safety feature that monitors the air pressure inside the tires. It alerts the driver when one or more tires are significantly under-inflated, potentially creating unsafe driving conditions.<>

Why is TPMS Important?

  • Safety: Properly inflated tires provide better vehicle handling and shorter braking distances.
  • Fuel Efficiency: Correct tire pressure helps optimize fuel consumption.
  • Tire Longevity: Maintaining proper tire pressure extends the life of your tires.

TPMS Types in Mercedes-Benz S Class

Mercedes-Benz S Class vehicles use a direct TPMS system. This means that sensors are installed inside each wheel to measure tire pressure directly.<>

Sensor Frequencies

Depending on the model year and region, Mercedes-Benz S Class vehicles may use either 315 MHz or 433 MHz TPMS sensors. It’s crucial to know which frequency your vehicle uses before attempting any sensor replacement or system reset.<>

General Steps for Resetting TPMS in Mercedes-Benz S Class

While the exact procedure may vary slightly between different generations, here’s a general overview of the TPMS reset process:<>

  1. Ensure all tires are properly inflated to the recommended pressure.
  2. Turn the ignition to the “ON” position without starting the engine.
  3. Navigate to the vehicle’s menu system using the steering wheel controls.
  4. Locate the TPMS reset option.
  5. Initiate the reset process.
  6. Drive the vehicle for a short period to allow the system to relearn the tire pressures.
