It has an automatic shut off so sometimes when your sitting at the stoplight or thought a drive though it sounds like your car has died but it hasn't.
IT IS A LUXURY CAR AND IS AN EXTREMELY COMFORTABLE RIDE. I LOVE THE BACKUP CAMERA IT HAS COME IN HANDY MANY OF TIMES. I DON'T LIKE ALL THE FEATURES THOUGH ONE I DISLIKE THE MOST IS WHEN YOU GO TO GET OUT OF THE CAR THE SEAT MOVES BACK, YES THIS WOULD BE NICE IN THEORY, BUT THE SEAT DOESN'T LIKE TO MOVE BACK TO WHERE IT WAS SO EVEN JUST A QUICK RUN INTO THE STORE LEADS YOU TO HAVING TO ADJUSTING YOUR SEAT EVERY TIME. THEN at other times the seat will move up to much, it really is a no win situation. I also believe there are almost to many features on the car that are overwhelming.
