NAV traffic question
 

Bought ES 2011 few weeks back. I know XM service provided real time traffic info in NAV. Say i am driving in a particular location, is it possible to get list of all the traffic warning (accidents/construction etc) covering 50 mile radius?
I used to have this feature in my Audi Q5. Just wondering whether i can get this in Lexus. I have not come across the answer so far from the manuals.
