New spectroscopic estimations of effective temperatures and absolute stellar magnitudes in various phases of the unique Cepheid V473 Lyr are presented. These estimations are obtained using the new spectroscopic method based on calibrations of absolute stellar magnitudes with effective temperatures and new spectroscopic indicators-line-depth ratios. New data and photometric observational data were analyzed. We conclude that V473 Lyr really pulsates in the 2nd or higher overtone mode.
