Some days ago, I was meddling with some settings in the menu. After that, the truck beeps many times (a long string of beeps, maybe 7 or 8 times or even more) when I close the door and leave the truck. But sometimes, it does not make any beeps at all, even I forget the key inside the truck. I could not find out which setting change cause the problem. Anyone could shed a light on it? Thank you!
