Added sound equipment may interfere with the operation of your vehicle's engine, radio, or other systems, and even damage them. Your vehicle's systems may interfere with the operation of sound equipment that has been added. Notice: The chime signals related to seat belts, parking brake, and other functions of your vehicle operate through the GM radio/entertainment system. If that equipment is replaced or additional equipment is added to your vehicle, the chimes may not work. Make sure that replacement or additional equipment is compatible with your vehicle before installing it. See Accessories and Modifications on page 5-3. Figure out which audio system is in your vehicle, find out what your audio system can do, and how to operate all of its controls. Your vehicle has a feature called Retained Accessory Power (RAP). With RAP, the audio system can be played even after the ignition is turned off. See Retained Accessory Power (RAP) on page 2-20 for more information.
