Gothenburg - Volvo chief Stefan Jacoby has suffered a "mild stroke" and will be absent from work for at least a month, the Swedish carmaker said on Sunday.
The 54-year-old German received prompt medical attention and has "already started the recovery process," Volvo said.
Jacoby, a former Volkswagen boss, took over at Volvo in August 2010 after it was sold by Ford to Chinese firm Geely.
"I was lucky that it was a mild stroke," said Jacoby. "I am currently experiencing limited movement abilities in my right arm and, to some extent, also in my right leg. I have started to recuperate and already notice certain improvements."
The company's finance chief Jan Gurander is to serve as acting chief executive during Jacoby's absence.
