I cant seem to get the bonnet up! I pull the lever in the car and it releases but the safety catch in the middle of the griulle doesnt want to move any direction. Hence the bonnet wont release from the safety catch. I didnt get an owners book with the car. Is there another safety catch, or is the thing in the middle of the grille not the safety catch at all? It needs some oil and im on a motorway trip tommorrow..... Mal
