Stop chicane, which caused Frentzen to run onto the grass. He retaliated by slowing Coulthard into La Source corner at the start of his following lap. Herbert and Barrichello were ninth and tenth; Barrichello spun at the chicane during his third run after locking his brakes. Fisichella, eleventh, missed the top ten by three-tenths of a second on his only quick run of the session. Herbert's teammate, Eddie Irvine, qualified twelfth with tyre-grip problems. He was ahead of Zonta in the slower of the two BARs (which lost a half-second through Eau Rouge), Heidfeld in the faster Prost, Sauber's Pedro Diniz and Arrows driver Pedro de la Rosa. Alesi qualified 17th, despite spinning at the Bus Stop chicane and triggering a yellow flag, which prevented several drivers from lapping quicker. Salo qualified 18th due to car issues caused by a lack of grip, ahead of Wurz (who had engine problems that caused smoke to billow from it on the entry to the Bus Stop chicane on his out-lap and shared the spare Benetton monocoque with Fisichella). Verstappen, after a braking error at La Source, and the two Minardi drivers of Gené and Mazzacane qualified at the back of the grid, in positions 20 to 22. Qualifying classification Warm-up The drivers took the track at 09:30 Central European Summer Time (UTC+2) for a 30-minute warm-up in wet weather, with lap times 13 seconds slower than the previous days' practice and qualifying sessions. Heavy rain fell early in the morning from 5:00 am and it increased incrementally before stopping; a rising mist formed low on the track by dawn. Drivers used full-wet tyres on the slippery racing surface and later intermediate rain tyres when the track began drying out. Häkkinen set the fastest lap time of the session at 2:03.392. Michael Schumacher was the second-fastest driver; Button was third, two-thousands of a second slower than Schumacher. Barrichello was fourth and Coulthard completed the five fastest drivers. After spinning sideways because one of his rear wheels touched a damp white line, Fisichella struck the tyre barriers at Stavelot corner with enough force to launch him into the air. He landed upside-down on the roll-hoop of the vehicle; the session was suspended for approximately 20 minutes while marshals cleared the track of debris and repaired the wall. Fisichella sustained a bruised left knee, and was forced to start the race with his team's spare
