You have to use SetVehicleParamsEx. Example for engine command:

pawn Код:

CMD:carengine(playerid,params[])
{
     new engine,lights,alarm,doors,bonnet,boot,objective;
     GetVehicleParamsEx(vid,engine,lights,alarm,doors,bonnet,boot,objective);
     SetVehicleParamsEx(vid,1,lights,alarm,doors,bonnet,boot,objective);
     SendClientMessage(playerid, -1, "Engine turned ON");
     return 1;
}
