The results from XMM-Newton observations of the relaxed cluster of galaxies Abell~496 are presented. The spatially-resolved X-ray spectra taken by the European Photon Imaging Cameras show a temperature drop and a Fe abundance increase in the intra-cluster medium (ICM) towards the cD galaxy at the cluster center. The abundances of Si and S also show a central enhancement. High resolution soft X-ray spectra obtained with the Reflection Grating Spectrometers provides a strong constraint on the temperature structure in the central cool plasma. Furthermore, the O abundance at the cluster core is accurately measured based on the OVIII Ly alpha line detected with the RGS. Contrary to the Si, S, and Fe abundances, the O abundance is radially constant over the cluster.
