The first-generation Mercedes GLC Mk1 (X253) (2015–2022) replaced the boxy GLK with a sleek, comfortable mid-size SUV on the MRA platform, sold in petrol, diesel and plug-in hybrid forms. After servicing, several electronic systems expect resetting. The oil service reset through the Assyst Plus service system clears the wrench from the instrument display once fresh oil and a filter are in. A TPMS reset relearns tyre pressures after a rotation, the brake pad wear warning needs clearing when new pads and sensors are fitted, and steering angle calibration follows alignment work. A replacement 12V battery should be registered so the energy management adapts. Choose the service reset procedure that matches your GLC from the list shown directly below.
