Just go to: http://gmownercenter.yahoo.com (The Chevrolet Owner Center - Hosted by Yahoo) If you don't have a Yahoo account, you will need to create one to enter (no cost). From there, just answer the questions about the vehicle you have. After you add your vehicle, you'll see a link to download the owners manual. If you add your truck based on year and model, you won't see Silverado in the list under Chevrolet. You will have to choose 1500 but it will be the correct owner's manual.
