Switch ignition on. The standard display of the control system appears. Press the up or down button on the multifunction steering wheel until the FSS indicator appears in the multifunction display. Press the reset button for about four seconds. This message will appear in the multifunction display: SERVICE INTERVAL? RESET WITH R BUTTON FOR 3 SEC.
