DIC Vehicle Customization (With DIC Buttons) Your vehicle may have customization capabilities that allow you to program certain features to one preferred setting. Customization features can only be programmed to one setting on the vehicle and cannot be programmed to a preferred setting for two different drivers. All of the customization options may not be available on your vehicle. Only the options available will be displayed on your DIC. The default settings for the customization features were set when your vehicle left the factory, but may have been changed from their default state since then. The customization preferences are automatically recalled. To change customization preferences, use the following procedure.
