MapMvcAttributeRoutes() extension method only available in MVC version 5 or higher, because RouteCollectionAttributeRoutingExtensions class doesn't exist in previous versions. Using that method in MVC 4 or below will show this error:

'RouteCollection' does not contain a definition for 'MapMvcAttributeRoutes' and no extension method 'MapMvcAttributeRoutes' accepting a first argument of type 'RouteCollection' could be found.

If you want to use attribute routing in MVC versions older than MVC 5, install AttributeRouting package then use AddRoutesFromController() method to add controller name into routing configuration inside RegisterRoutes method (ControllerName belongs to any controller class name):

public static void RegisterRoutes(RouteCollection routes)
{
    routes.IgnoreRoute("{resource}.axd/{*pathInfo}");
    routes.MapAttributeRoutes(config =>
    {
        config.AddRoutesFromController<ControllerName>();
    });
}

Then, you can use RouteAttribute (and RoutePrefixAttribute) similar to MVC 5 fashion:

[RoutePrefix("Cars")]
public class CarsController : Controller
{
    [Route("Cars/Index")]
    public ActionResult Index()
    {
        // do something
    }
}

You can found detailed information of AttributeRouting package usage here.
