Welcome to the forum.
If you'd like the owners manual that fits in the glove box (rather than the downloaded copy), go to Ebay, click on "MOTORS", then search on your year, the word "owners manual", "Ford F150" (Ex: 2005 owners manual Ford F150). They are available for cheap, and are sold with the black zip bag for under 10 bucks.
At the very least, download one from the link that was posted above; it provides good information. Lots of questions get asked here that can be answered from reading the owners manual, such as buying/reprogramming spare key proceedure, your fuse assignments/location, etc.
Give an answer, they learn for the day; suggest a search, they learn for a lifetime.
