ask ko lang po sana regarding backup sensor if normal ba to hear an initial long beep when you shift to reverse? I was expecting kase to just hear a short beep telling you that backup sensor has been activated. It's been like this since I acquired the vehicle, kahit walang obstruction, nakakahiya sa mga passengers ko coz talagang masakit sa tenga. the rest of the beeps naman works normally when detecting obstructions.
