I got a 2010 E350 Coupe with P1, P2, and appearance.
I'm guessing that the camera sensor options should be included in either P1, or P2. When I drive close to objects (either side or front of the car) the car doesn't alarm me. How can I know whether my car has this option or not, or if the sensors don't function properly?

 

The E350 coupe isn't cheap, and its standard-equipment list lacks some of the mundane fare found on cheaper premium/luxury cars, such as heated seats, iPod connectivity, a backup camera, parking sensors, active xenon headlights.
