Starting in seventh position, the Olympic champion in the discipline finished her course in 53 sec 79/100th, ahead of the German Lena Duerr by 18 hundredths of a second and the American Mikaela Shiffrin by 42 hundredths.
The Slovak, third in the giant slalom in Sölden (Austria) two weeks ago for the opening of the World Cup, has already won the Levi slalom five times, notably achieving the 2020/2021 double.
Last year in Lapland, she was relegated to third place during the two weekend races, where Shiffrin, winner last season of the general classifications and the specialty, won each time.
The second round is scheduled to begin at 1:00 p.m. French time.
