The Tire Pressure Monitoring System (TPMS) in your Mercedes-Benz S-Class is designed to alert you when tire pressure is too low, ensuring your safety and optimal vehicle performance. Understanding how the system works and knowing how to reset it after adjusting tire pressures can help prevent unnecessary alerts and keep your driving experience smooth.

How the TPMS Works

The TPMS uses sensors located in each tire to monitor air pressure levels continuously. When the pressure drops below the recommended threshold, the system triggers a warning light on your dashboard. This prompt allows you to check and correct tire pressure before it affects handling or fuel efficiency.

Steps to Reset the TPMS on Your Mercedes-Benz S-Class

  • Ensure all tires are inflated to the manufacturer’s recommended pressure, found on the driver’s door jamb or owner’s manual.
  • Turn on the ignition without starting the engine.
  • Navigate to the vehicle settings menu on the infotainment screen.
  • Select the “Service” or “Vehicle” submenu, then choose “TPMS Reset” or “Tire Pressure Reset.”
  • Confirm the reset and wait for the system to recalibrate, which may take a few minutes.
  • Drive the vehicle at speeds above 20 mph for several minutes to complete the reset process.

If the TPMS warning light remains on after resetting, double-check tire pressures or consult your Mercedes-Benz dealer for further diagnostics. Regular maintenance of your tires and TPMS ensures safer driving and extends the life of your tires.
