2013 RDX base. Battery was completly dead. Needed to shift to neutral to push out of garage to get a jump. How do you shift from P to N with no power??????

 

Pry up the little piece of plastic to the right of the shifter (shift lock lid). There will be a release you have to press down on to shift. This should be outlined in your owner's manual.

Look at picture under item #17 on this link:
