The formation lap in F1, also known as the warmup lap, is the slow lap drivers take before the start of the Grand Prix

The pitlane and grid open 40 minutes before the race and the teams set the cars up in their grid box. The start of the race is preceded by the cars doing a low-speed lap of the circuit, a formation lap, behind the safety car to warm their tyres and have one last look at the track before the race starts. 

Once all the cars have returned to the grid and positioned themselves in their grid box the starting procedure is initiated.
