Although the world champion was ultimately given a reprimand for aborting his entry into the pits with 15 laps to go, radio communications with the pitwall revealed how seriously Mercedes took the risk of a penalty.
It had already called off Hamilton's fight with team-mate Valtteri Bottas, and then denied Hamilton's request to turn his engine down in the closing stages.
Instead Hamilton's engineer Peter Bonnington pushed Hamilton to keep building up a gap over Bottas right the way to the finish line.

Those messages alerted Hamilton who, just after taking the chequered flag, queried whether he had already been given a penalty.
Speaking about the reasoning for Hamilton being urged to extend his advantage over Bottas, Mercedes boss Toto Wolff said: "We were covering all bases. You know these things. [There] is pretty much room for interpretation.
"We just wanted to disappear in the distance as much as we could."
Here is an edited transcript of how conversations between Hamilton and Bonnington played out in the closing laps:
