Mercedes executive director Toto Wolff has warned his drivers to keep their concentration when they look to extend their winning run at next weekend's Monaco Grand Prix.
The Silver Arrows' Lewis Hamilton and Nico Rosberg have won all fives races so far this season, with the Briton registering four victories in a row and taking the lead in the drivers' championship.
However, Wolff is under no illusions about what Mercedes will need to do win in Monte Carlo.
He told reporters: "It's about avoiding mistakes. The drivers have no room for error and neither does the team."
"We have been pushing hard since the last race and nobody will be backing off in our teams at Brackley, Brixworth and Stuttgart. We are heading to Monaco with our feet on the ground because it is a place that can bite you if you get over-confident.
"We have a quick Silver Arrow and Lewis and Nico are specialists around the streets. But we need to bring every piece of the puzzle together if we want to maintain our run of success next weekend."
Mercedes have opened up a lead of 123 points in the constructors' championship, with Red Bull as distant second.
