Every model year of the Mini Cooper S is equipped with a service reminder system that triggers a warning light when it is time for maintenance. The internal computer tracks engine conditions to calculate when service is needed. After the routine service has been performed, the warning indicator should be reset so the computer can track the changes thereafter. Many automotive technicians will reset the service warning when they perform maintenance on your Mini Cooper, but if they don't, you can reset the light yourself.

Press the "Start" button. Wait for the service warning light to appear in the display.
Press and hold both the left and right side buttons beside the odometer as soon as the service warning light disappears.
Release the right side button for no more than one second after the current time is shown on the display. Press and hold the right button again.
