good evening sentence. While the 2011 model uses an LPG in 30,000 vehicles with an ATKER brand LPG in 113,000, it does not knock, even though it is not continuous when shifting from 1st gear to 2nd gear. There is no problem in other gear shifts. When I use the vehicle in gasoline, the knob that shifts from 1st gear to high disappears from there. Thank you from now.
