The team, who won the Hungarian Grand Prix before the summer break, have installed an update on the W04 for Sunday's race, which will take place on the Korean International Circuit.
"The Yeongam circuit is a combination of long straights and mainly slow to medium-speed corners that should suit our car, which will also receive an aerodynamic update for this race," ESPN quotes Wolff as saying.
"We have six races to go this season and a clear target of securing second place in the constructors' championship. To achieve that, we need to maximise every opportunity that comes our way with both Nico and Lewis, beginning this weekend."
Mercedes have secured just one podium place since their win in Hungary.
