On my (new to me) 12 Grand Cherokee - I have 3 arrow buttons on the left spoke of the steering wheel, as well as the phone and the other one. I can't get any thing to happen with the arrow buttons - like tire pressure, engine temp or anything. Am I doing something wrong? My wife is able to use the hands free telephone option, but I'm only interested in engine status and such. I have read the owners manual but I guess my reading comprehension is not what it should be. Any help would be greatly appreciated.
