Follow live coverage of FP2 and the rest of Mexican Grand Prix weekend from the Autodromo Hermanos Rodriguez with F1i.
Max Verstappen set the pace during an eventful first practice session, with the Toro Rosso driver actually cutting a corner on his fastest lap but being allowed to keep his time. Daniil Kvyat was second quickest - setting an identical time to Kimi Raikkonen in third - with Sebastian Vettel and Daniel Ricciardo fourth and fifth respectively.
Mercedes endured a tricky opening session, with Nico Rosberg sixth and Lewis Hamilton down in 11th place. Rosberg spent a number of minutes in the pits after his rear brakes caught fire when he overtook Vettel in to Turn 12.
The circuit is low on grip at this early stage of the weekend, with a number of drivers struggling for traction. Valtteri Bottas and Felipe Nasr both had spins during the first session with the latter coming dangerously close to hitting the wall on the outside of the penultimate corner.
A busy start to FP2 is expected, with a threat of rain increasing after a largely dry opening session on Friday morning.
Formula One returns to Mexico for the first time since 1992, with the refurbished circuit in Mexico City having previously hosted a round of the world championship from 1963-70 and 1986-92.
The teams will face a unique challenge at the Autodromo Hermanos Rodriguez, with the circuit situated 2219 metres above sea level, with the altitude impacting on downforce. While the cars will run maximum downforce, the difference in air pressure means they are predicted to perform as if using Monza-specification low downforce levels.
