when the track was ready for intermediates, and Juan Pablo Montoya, who did his qualifying lap on intermediates as it began to rain. Race Trulli's Renault had a good start from pole position, but second-placed Schumacher's Ferrari did not, and he lost positions to Fernando Alonso's Renault and David Coulthard's McLaren. At La Source, Mark Webber's Jaguar collided with Barrichello's Ferrari, causing Webber to lose his front wing and Barrichello to suffer rear wing damage. In a separate incident, Räikkönen's McLaren made contact with Felipe Massa's Sauber, which caused Massa to lose his front wing. In a third incident, Nick Heidfeld's Jordan and Olivier Panis's Toyota made contact. Going into Eau Rouge, Webber was side-by-side with Takuma Sato's BAR, and they collided in the middle of the corner whilst they were overtaken by Montoya's Williams. The contact broke Sato's left rear suspension and Webber's front right suspension. Sato consequently spun in the middle of the track. The rest of the field attempted to avoid the spinning BAR, but in doing so, Zsolt Baumgartner and Gianmaria Bruni, both driving for Minardi, made contact, putting Bruni out of the race and getting him hit by Giorgio Pantano's Jordan. Sato, Webber, Bruni, and Pantano were out of the race. A small fire on Bruni's car, caused by the contact with Pantano, forced the safety car to come out. During this time, Button, Massa, Barrichello, Heidfeld, Baumgartner, and Olivier Panis stopped for repairs caused by debris. Massa and Barrichello stopped twice. The safety car came in at the end of lap four and Trulli led Alonso and Coulthard. Räikkönen overtook Schumacher for fifth position and Button overtook Ricardo Zonta's Toyota. Schumacher continued to be slow, losing 1.1 seconds to Räikkönen in the middle sector on lap five, enabling Montoya to overtake him around the outside of the Bus Stop chicane on lap five. On lap six, Räikkönen overtook his teammate, Coulthard, for third, going up the inside at the Les Combes chicane. On lap eight, Barrichello overtook Baumgartner and Heidfeld, putting him into 14th place. Christian Klien, in the sole remaining Jaguar, was the first driver to make a scheduled pit stop, on lap nine, and race leader Trulli made a pit stop on lap 10, rejoining in ninth place. Alonso now led the race, but on lap 12 he had an oil leak and spun twice at Les Combes, losing the lead to
