his feeling he could have improved further as he ran over gravel scattered by Luciano Burti's Prost at turn 13 causing him to make a minor mistake. His teammate Häkkinen had minor engine vibrations and an error on his final timed lap put him fourth. Trulli and Frentzen took fifth and seventh for the Jordan team. Trulli was pleased with the balance of his car and later apologised to Michael Schumacher for slowing the Ferrari driver while Frentzen was baulked by Panis. They were separated by Montoya's slower Williams who was pleased with how his car felt but was annoyed with Alesi who blocked Montoya during his last timed lap towards its conclusion. A handling balance problem that made his car anxious under braking and launched over the kerbs at the turn 13/14 chicane restricted Barrichello to eighth. Heidfeld made minor adjustments to improve the vehicle's balance and took ninth. Villeneuve used the first half an hour to adjust his front and rear flaps and took tenth, although he lost time through turn one. Panis took 11th after heavy traffic slowed his final timed lap. Irvine, 12th, spun twice during the session and Räikkönen in 13th expressed disappointment of the balance of his car. 14th-placed De La Rosa was kept from the circuit due to an electrical fault at his part of the garage and engine overheating and driver errors affected his on-track running. Burti's car was altered at midday and pirouetted his car on his third timed lap as he qualified 15th. Fisichella and Button of the Benetton outfit took 16th and 17th: Button was prevented from setting a faster lap because he forgot to change the setting of his differential exiting Estroil corner because he was too focused on the lap and he only remembered to alter the differential setting when he got to the Adelaide hairpin. Verstappen in 18th could not adapt the Arrows A22 to the track and he was ahead of 19th-placed Alesi spun at high-speed leaving the Imola chicane. Bernoldi was unable to extract additional speed from his car and took 20th. The two Minardis qualified at the rear of the field in 21st and 22nd places: Fernando Alonso was slowed on his final timed lap by Bernoldi, and his teammate Tarso Marques had a large amount of understeer that affected the handling of his chassis, which could not be rectified.
