I bought my 2013 Focus hatchback used about three weeks ago, and I learned something new today about the car. A friend of my stepson came over and asked about the spare tire. I showed him the spare tire area, and noticed two plastic pieces laying on the styrofoam area around the tire.there. I didn't think anything of them at the time. Later on I went back into the trunk, pulled up the spare tire cover, and noticed one piece said to replace it after servicing the battery. I pulled both pieces out, and lo and behold, the two pieces fit together to form a battery cover. I then proceeded to install the cover over my battery. Should keep the top of the battery clean.
