Abstract: We clarify the problematic aspects of gravitational interaction in the weak field limit of Kaluza-KIein models. We explain why some models meet the classical gravitational tests, while the others do not. We show that variation of the total volume of the internal spaces generates the fifth force. This is the main reason of the problem. It happens for all considered models (linear with respect to the scalar curvature and nonlinear f(R), with toroidal and spherical compactifications). We explicitly single out the contribution of the fifth force to nonrelativistic gravitational potentials.
