NotificationCompat.CarExtender

public static final class NotificationCompat.CarExtender
extends Object implements NotificationCompat.Extender

java.lang.Object
↳	android.support.v4.app.NotificationCompat.CarExtender

Helper class to add Android Auto extensions to notifications. To create a notification with car extensions:

Create an NotificationCompat.Builder, setting any desired properties.
Create a NotificationCompat.CarExtender.
Set car-specific properties using the add and set methods of NotificationCompat.CarExtender.
Call extend(NotificationCompat.Extender) to apply the extensions to a notification.
Post the notification to the notification system with the NotificationManagerCompat.notify(...) methods and not the NotificationManager.notify(...) methods.

 Notification notification = new NotificationCompat.Builder(context)
         ...
         .extend(new CarExtender()
                 .set*(...))
         .build();

Car extensions can be accessed on an existing notification by using the CarExtender(Notification) constructor, and then using the get methods to access values.
