How to reset Mercedes tyre pressure?

Resetting the TPMS (Tyre Pressure Monitoring System) requires a few simple steps:

  1. Ensure all tyres are properly inflated by following the recommended guide so that the PSI is correct on all 4 tyres.
  2. Insert the key into the ignition and turn it to the "on" position, but do not start the engine.
  3. Locate the "Menu" or "Settings" button on the dashboard, then press it to access the vehicle settings menu. Use the arrow keys or rotary knob to navigate to the "Tyre Pressure" or "TPMS" option and select it.
  4. Look for the option labelled "Reset" or "Relearn" and select it. Depending on the Mercedes model, you may need to hold down the "OK" button for a few seconds to initiate the reset process.
  5. After initiating the TPMS reset, drive the vehicle at speeds above 20 mph for at least 10-15 minutes to allow the system to recalibrate and recognise the new tyre pressure levels.
  6. After driving the vehicle for the required time, check the TPMS status to ensure that all four tyre pressure readings are being displayed correctly. If any tyre pressure readings are still incorrect, there may be an issue with the sensors or the tyres themselves, and it may be necessary to have the vehicle inspected by a qualified technician.
