To reset the 2009 Ford Focus' service light. Close all the doors and turn the key to the "off" position. Press and hold the brake and accelerator pedals down together.

Remember to schedule regular oil and filter changes for the Focus every 7,500-10,000 miles or 12 months when using synthetic products and every 3,000-5,000 miles when using conventional products. Cost for a lube and filter change averages between $110-$122 in materials and labor.
