Coming out of a store and when I hit my unlock button on the keey fob the tail lights don't light up to let me know where the car is anto let me know the car unlocked. The only thing that happens is the interior ligh comes on. Ths sucks. I'm used to my GM autos working like this and for some reason I thought this car did it as well. Is there a way to make this happen? Or am I stuck with no exterior lights when I use the fob?
