Toto Wolff insists he is "not worried" Mercedes’ controversial suspension system will be declared illegal by the FIA.
A dispute is raging between Mercedes and Red Bull, who are using a linked suspension concept, and another camp led mainly by Ferrari.
It has raised the spectre of a controversy and protest-riddled 2017 season opener in Melbourne.
But Mercedes team boss Wolff said: "I am not worried.
"The FIA has assured us several times that we are legal," he is quoted by Auto Motor und Sport. "It is the usual sabre-rattling before the season."
