In this study, we analyze the implications of the non-universal $Z^\prime$ model to the lepton polarization asymmetries and the cp violation for the decay channel $B\to K^*\ell^+\ell^-$ where $\ell=\mu^+\mu^-$. To study the influence of the $Z^\prime$ on the mentioned observables we used the UTFit constraints for the parameters of $Z^\prime$. We have found that these observables are sensitive to the coupling of the $Z^\prime$ boson with the fermions. Therefore, the accurant measurements of these observables could provide help to extract accurate values of $Z^\prime$ couplings.
