Michael Schumacher remains in a stable but critical condition in hospital, his manager Sabine Kehm has said.
Sabine Kehm said he was being carefully looked after, and that she would not comment on rumors about his condition.
Michael Schumacher is in a medically induced coma in hospital in Grenoble, after he suffered head injuries in a skiing accident in the French Alps on Sunday.
Doctors said on Tuesday that the F1 champion had shown signs of improvement.
But they added that he was still “not out of danger”.
They will not give any update on Michael Schumacher’s condition on Wednesday unless it changes significantly, Sabine Kehm said.
“The good news for today is… there’s no significant changes,” Sabine Kehm told reporters and well-wishers outside the hospital.
But she added that the situation remained critical.
Doctors say they cannot give a prognosis for his condition in the coming days and months.
But it is medically possible for someone to spend several weeks in an induced coma and fully recover from it.
Michael Schumacher had been skiing off-piste when he fell and hit his head. His helmet cracked on impact after hitting a rock.
Sabine Kehm said that Michael Schumacher was not skiing with just his teenage son, as had been reported, but also with a group of friends.
