Turn the ignition switch to the first position. Simultaneously press and hold the 'OK' button (S110s6) on the multifunction steering wheel and the 'Answer/End' button on the right side for about 5 seconds. Select 'ASSYSTPlus workshop' and confirm by pressing the 'OK' button (S110s6). Use the 'Forward/Backward' button (S110s1) to select 'Service Performed' and confirm by pressing the 'OK' button (S110s6). Choose 'Complete (Full) Service' or 'Individual'.
