Toto Wolff says Mercedes must make sure it learns from the failure which caused Nico Rosberg to retire from last week's Italian Grand Prix.
Reliability issues heavily compromised Rosberg's weekend at Monza, with a leak ahead of qualifying forcing him to change to an old specification engine which ultimately failed in the closing laps of the race. Mercedes was also investigated for having tyre pressures lower than the Pirelli minimum on the grid, but escaped punishment.
Wolff says Mercedes needs to understand why it faced the issues it did in Italy and ensure there are no repeats this weekend in Singapore.
"Monza was not an easy weekend," Wolff said. "Both drivers produced very strong performances - but unfortunately only one got the result he deserved. When you are in a position like we currently enjoy, expectations are extremely high - and none more so than among our own people.
"This was our first retirement of the season which shows how far we have come but also that we are not invincible. Every detail matters and we are trying to take care of all of them. So, we take lessons from our failures and look to get back on top with both cars in Singapore.
"This won't be easy, however, at a circuit which provides one of the toughest tests of man and machine on the calendar. We must be at our best here - and at each race that follows - to make sure the job is done."
