Nico Rosberg gave the team their first win since their 2010 return to Formula 1 with victory at the Shanghai International Circuit last season.
The team's CEO told Autosport.com: "One year on from Nico's win, a lot of people will be asking whether this is something our team can repeat in 2013. But like they say, yesterday's home runs don't win today's games, and that's definitely true for us.
"We start again from zero this year and need to work hard to adapt the car to suit the circuit and the tyre compounds we have available, in the conditions that we find on track next weekend.
"Our aim has to be to improve on our good start to the season and continue scoring good points in both championships."
Mercedes sit fourth in the constructors' standings after two races.
