Lewis Hamilton went fastest despite enduring a less-than-ideal third practice session as drivers made their final preparations for qualifying at the Brazilian Grand Prix.
Having gone fastest in FP1, world champion Hamilton was pipped by Mercedes team-mate Nico Rosberg in Friday's second session.
The British driver, looking for his first win at Interlagos, reclaimed top spot in FP3 on Saturday but was initially hindered by a number of setbacks.
Hamilton spent part of his first out lap parked at the side of the track complaining of gearbox issues - drawing similarities with a concern that briefly affected Rosberg on Friday.
A sensor problem was subsequently blamed for the issue, forcing the car to go into neutral unexpectedly, before Hamilton spun off after losing the back end of his car.
Hamilton was able to continue the session and eventually toppled Rosberg with a lap of one minute and 12.070 seconds after switching to the soft tyre, with Ferrari's Sebastian Vettel third fastest once again.
