Well, the vivbration begins at 130km/hyy begins by vibrating the car and then it is transmitted to all sides, steering wheel, dashboard, etc ... It doesn't matter the march that you wear gear and that goes to celerando or not, it is more you can put the car in point dead and continue to vibrate the same, what if it gives me the impression is that it vibrates a little more when it goes in charge, that is, that is, that is,也就是说,也就是说,这更多。
