I doubt there is much difference between 2014 and 2016 vehicles as far as front-park assist sensors are concerned. They are hopeless.
A) they are not linked to the display, so you don't know which side is causing the beep;
b) an area around the centre at front appears to be out of sensor range, so that you are likely to hit the tow-bar of the vehicle in front, if you tend to rely on the sensors alone.
c) beep unnecessarily after a few seconds after you stop, especially at traffic lights - can't understand why. Sometimes it is a single beep, sometimes a couple of beeps, at times beeps continuously, which is irritating. Especially when there is no traffic on either side or in front when stopped in the center lane.
