The FIA will take a no-nonsense approach to Formula 1 drivers abusing track limits at the first sequence of corners at the Singapore Grand Prix.
Cutting inside the apex at Turn 2 as the track turns to the right gives drivers a clear benefit, so the FIA has moved to deter anyone from trying to gain an advantage this way.
In the pre-event note sent to teams on Thursday, the FIA revealed a cone has been situated further down the run-off area on the outside of the complex.
F1 race director Charlie Whiting wrote: "Any driver who fails to negotiate Turn 2 by using the track, and who passes completely to the right of the orange kerb element, must keep to the right of the red and white polystyrene block and rejoin the track on the outside of Turn 3."
The FIA has also confirmed that several areas of the Marina Bay track have been resurfaced.
This includes Turn 1 and Turn 2, a 100-metre section after Turn 5, and areas between Turns 12 and 13, and around Turns 15, 16 and 17.
There has also been a minor change to the width of the pitlane, with the pit wall having been moved 275mm away from the garages, to increase the width of the fast lane.
More TecPro barriers have been installed throughout the circuit as well.
