Kia started partial production at its plant in Zilina, Slovakia, on Monday after a two-week stop due to the coronavirus crisis.
The factory will operate on a limited basis initially with only two of the normal three shifts operating, Kia Europe told Automotive News Europe in an emailed statement.
The Zilina plant is Kia's only European production base. It builds the Ceed compact-car range and Sportage SUV.
Output will be influenced by factors including the availability of components, as well as guidance issued by local public health authorities, Kia said.
"We are adapting production of certain models and specifications based on the supply of parts," Kia said in its statement.
Among safety measures put in place to protect the health of workers are two tents with thermocameras where employees' temperatures are measured before they enter the factory, Kia Slovakia said on its Facebook page.
Kia temporarily closed the plant on March 23 as the coronavirus outbreak worsened.
