off the circuit. Michael Schumacher stayed fastest for the final day's running. The Autódromo José Carlos Pace underwent safety changes following the previous year's race. Twenty-one cabins were installed to protect marshals across the track in response to the death of marshal Graham Beveridge at the Australian Grand Prix. Animals roaming near the circuit perimeter were rounded up and taken to another location. A guard rail was installed at the Bico do Pato curve after the speed of Formula One cars had greatly increased from 2000. The gravel trap on the Reta Oposta straight was reinforced and the circuit's drainage system was repaired. The renovation work had been disrupted on 17 March when a contractor became dissatisfied with São Paulo city administration and enquiries were initiated. The dispute, over the delayed delivery of tables and chairs, was confirmed by race organisers and would not interfere with the Grand Prix. Barrichello was critical of the Grand Prix citing the dissatisfaction of some drivers in past years and the quality of the local facilities.

The drivers, however, were unhappy at the work as the track still remained bumpy. McLaren driver Mika Häkkinen described the track as "very bumpy indeed. It seems to get worse and worse every year." Minardi's Fernando Alonso claimed that the bumping was so bad that the drivers could have lost their vision of the circuit. Practice Four practice sessions were held before the Sunday race—two on Friday, and two on Saturday. The Friday morning and afternoon sessions each lasted an hour. The third and final practice sessions were held on Saturday morning and lasted 45 minutes. The Friday practice sessions were held in dry weather conditions and on a dirty track which gradually cleaned up as the session progressed. Michael Schumacher outpaced the other drivers in the first practice session, setting a lap of 1:16.832. Häkkinen was second-fastest and was initially quickest during the first quarter of the session. The formation continued with Barrichello and Coulthard third- and fourth-fastest, respectively. Olivier Panis was fifth-quickest, ahead of both Jaguars of Eddie Irvine and Luciano Burti. Juan Pablo Montoya, Heidfeld and Jarno Trulli rounded out the top ten fastest drivers in the session. In the second practice session, Coulthard set the fastest lap of the day,
