for the rest of the lap as Webber and Räikkönen pressured him. Further down the order, Montoya moved from ninth to fifth. Heidfeld became the Grand Prix's first retirement on lap nine when his engineers informed him over the radio of an oil feed problem that cut out his engine. He pulled off to the side of the track to ensure that no oil was deposited on the racing line. On lap ten, Räikkönen overtook Barrichello for second at the Senna S chicane and lost third when Montoya passed him later that lap. There were overtakes further down the field on that lap. Ralf Schumacher moved past Trulli for sixth and Pizzonia passed Verstappen for fifteenth. On the 11th lap, Räikkönen closed up to his teammate Coulthard and passed him to take the lead on the approach to the Senna S chicane.

Ralf Schumacher began to recover lost positions with an overtake on Villeneuve for tenth on the 12th lap. At the front of the field, Räikkönen had increased his lead over Montoya to five seconds by lap 14. On the same lap, Montoya reported a loss of rear tyre grip to his team over the radio and ran wide leaving Juncao turn. Coulthard overtook Montoya for second. As the circuit began to dry, except for turn three which continued to have water stream across it, Coulthard began to close up to his teammate Räikkönen, as Michael Schumacher overtook Webber on the inside for fourth on lap 15 leaving Arquibancdas turn. On the 16th lap, Michael Schumacher moved into third position with a pass on the slower Montoya around the outside at the Bico de Pato corner. Wilson drove through a river at the Curva do Sol turn and aquaplaned off another on the following lap. He retired after he was unable to restart his car. Coulthard drew close enough to his teammate Räikkönen by the 18th lap, just as Barrichello moved past Webber for fifth place.
