I have not read my owners manual yet to see if this is in it or not but by luck I found that if you have your radio playing and just after you open the door you push the on/off button the radio will continue to play with the ignition switch in the off position. This allows you to listen to the radio with the doors open if you are detailing it or whatever and you don't have to listen to the door warning audible alarm. I just thought this was cool since all previous vehicles I don't recall this working this way but maybe they did? I just found it by luck when I went to push the button right after opening the door and noticed the radio keeps playing! Mike
