  In Kaluza-Klein model with toroidal extra dimensions, we obtain the metric
coefficients in a weak-field approximation for delta-shaped matter sources.
These metric coefficients are applied to calculate the formulas for frequency
shift, perihelion shift, deflection of light and parameterized post-Newtonian
(PPN) parameters. In the leading order of approximation, the formula for
frequency shift coincides with well-known general relativity expression.
However, for perihelion shift, light deflection and PPN parameter $\gamma $ we
obtain formulas $D\pi r_g/[(D-2)a(1-e^2)]$, $(D-1)r_g/[(D-2)\rho]$ and
$1/(D-2)$ respectively, where $D$ is a total number of spatial dimensions.
These expressions demonstrate good agreement with experimental data only in the
case of ordinary three-dimensional $(D=3)$ space. This result does not depend
on the size of the extra dimensions. Therefore, in the considered
multidimensional Kaluza-Klein models the point-like masses cannot produce the
gravitational field which corresponds to the classical gravitational tests.
