It's important that you make sure the car is in park and turned off before beginning the process of replacing your battery cables.

If you cannot locate your battery, refer to your owner's manual. It will show you how to locate and access your battery. Once you have located the battery, you will need to differentiate between the positive and negative terminals. Car battery cables are usually colored to match their use: red cables are positive, black cables are negative. In some cases, the wires may both be black, but they will have red and black boxes or accents at the ends of the cable. If there are no discernible colors visible, you can easily determine which is the negative cable by following them from the battery to the other end. Negative cables bolt directly to the body of the car or engine block, positive cables attach to the starter. The battery will have labels marked with a + and a sign. The plus is the positive cable terminal, the is the negative.
Summary: Put on safety glasses and gloves. Ensure the car is turned off. Locate the battery. Determine which is the positive and which is the negative terminal.
