An Auger-electron-ion coincidence method is applied to study the site-specific formation of metastable CO₂²⁺ in the C1s and O1s Auger decays of CO₂. It is found that only dication states with the electronic configuration of 1π_g^-2 are relevant to the metastable formation. These dication states are favorably produced in the O1s Auger decay, because of the charge distribution of the 1π_g orbital localizing at the O site. Fragmentation channels of dissociative CO ₂²⁺ states are also investigated.
