As Alonso eases up, the following Giancarlo Fisichella spins and provokes a chain-reaction accident that involves Nick Heidfeld, Kimi Räikkönen (who suffers a cut left-rear tyre and spins), Ralf Schumacher, Scott Speed (who spins), Takuma Sato and Tiago Monteiro. Heidfeld, Räikkönen, R. Schumacher, Speed and Sato pit at the end of the lap. Sato remains there until lap 16. Monteiro retires.
