Use a timed alert to let users know how much time they have to respond before a default action is chosen.

To create a timed alert message, use the Pane view within the[navigation template](https://developer.android.com/design/ui/cars/guides/templates/navigation-template), with[timed buttons](https://developer.android.com/design/ui/cars/guides/components/button)for the default action.
