  We consider Einstein-Maxwell-dilaton theory in four dimensions including the
Kaluza-Klein theory and obtain the general asymptotic solutions in Bondi gauge.
We find that there are three different types of news functions representing
gravitational, electromagnetic, and scalar radiations. The mass density at any
angle of the system can only decrease whenever there is any type of news
function. The solution space of the Kaluza-Klein theory is also lifted to five
dimensions. We also compute the asymptotic symmetries in both four dimensional
Einstein-Maxwell-dilaton theory and five dimensional pure Einstein theory. We
find that the symmetry algebras of the two theories are the same.
