* Lap 1: On pole position for the sixth time in his career – but the first as a Toyota driver – Ralf Schumacher leads away. Fellow front-row starter Jenson Button’s engine appears to be smoking shortly before the start and Giancarlo Fisichella passes him for second before the first turn. Button settles into third ahead of David Coulthard who makes a terrific start from sixth. Local hero Takuma Sato runs wide at the first corner – and Rubens Barrichello follows him into the gravel. Both rejoin, Barrichello pitting at the end of the first lap and Sato at the end of the second. Mark Webber grabs fifth from Christian Klien, Jacques Villeneuve and Michael Schumacher (a great start from 14th) but the German and Fernando Alonso demote Villeneuve before the lap is through. Felipe Massa, Kimi Räikkönen, Narain Karthikeyan, Christijan Albers, Tiago Monteiro, Robert Doornbos and Jarno Trulli (who started from the pits) complete the order. Approaching the chicane, Juan Pablo Montoya runs wide while challenging Villeneuve and smacks into the tyre wall. His car comes to rest by the edge of the track with a significant level of left-side damage.

* Lap 6: Barrichello makes his second stop while the safety car is still running.
