Head of Mercedes Motorsport Toto Wolff believes that improving reliability must be the squad's main focus as the Formula 1 season re-commences in Belgium this weekend.
Mercedes has a comfortable lead in the Constructors' championship but has endured reliability problems across the past three events; Nico Rosberg was forced to retire at Silverstone, while failures rendered Lewis Hamilton to the back of the grid at Hockenheim and the Hungaroring.
"Looking ahead to Spa, and also reflecting on our recent performances, it is clear that reliability must be a key focus for the team if we are to maintain the hard-earned advantage established in the opening stages of the year," said Wolff.
"We approach the remaining eight races with the firm target of making this next phase of the season even better than what we have achieved so far.
"Although the team has done a fantastic job, we are fully aware that this Championship is far from decided - as demonstrated clearly in Hungary by the performance of some of our competitors. As always, we are taking nothing for granted."
Championship leader Nico Rosberg added that every last point will count in his battle with team-mate Lewis Hamilton.
"The battle with Lewis has been so close all season - and it could well stay that way right up to the final race - so every last point will be crucial in that contest too," he said.
