  A chirally-motivated coupled-channel $\bar{K}N$ potential, reproducing all
low-energy experimental data on $K^- p$ scattering and kaonic hydrogen and
suitable for using in accurate few-body calculations, was constructed. The
potential was used for calculations of low-energy amplitudes of the elastic
$K^- d$ scattering using Faddeev-type AGS equations with coupled $\bar{K}NN$
and $\pi \Sigma N$ channels. A complex $K^- - d$ potential reproducing the
three-body $K^- d$ amplitudes was constructed and used for calculation of $1s$
level shift and width of kaonic deuterium. The predicted shift $\Delta
E_{1s}^{K^- d} \sim -830$ eV and width $\Gamma_{1s}^{K^- d} \sim 1055$ eV are
close to our previous results obtained with phenomenological $\bar{K}N$
potentials.
