Is it common that it beeps in normal circumstances? Like even when the car is parked it beeps for me.
The reason why it is beeping is because it may sense that there is something nearby that may cause a collision. I had the same problem when I was driving in rush hour and it would beep alll the time. I really dont see how this function is helpful specially in a place like India where the traffic is dense and collision chances are 99% unless the driver is very sharp.
What I did was i just turned off the front and lane collision warnings from the menu.
If you feel you need it then keep it. But i personally feel that its of no use to me in India.
