How do I reset the oil change indicator on a Ford Fiesta?

I just got my Ford Fiesta serviced and the oil change indicator is still on. How do I reset it?

To reset the oil change indicator, start by turning on your car's ignition without starting the engine. Then, press down on the accelerator and brake pedal simultaneously for 20 seconds. This should reset the indicator.

You can also reset the oil change indicator by disconnecting the car's battery for 10 minutes and then reconnecting it. This will reset all of the car's sensors.
