The FIA has warned against running wide at turn eight with punishment likely should they do it repeatedly during the race.
Several drivers had their fastest qualifying lap time deleted on Saturday after all four wheels crossed the white line denoting the circuit boundary.
A note issued by Charlie Whiting on Sunday morning said the stewards would be keeping an eye out for any drivers who gain an unfair advantage by running wide, or those who do it on several occasions.
“During the race, any driver leaving the track on the exit of turn 8 who appears to have gained a clear and lasting advantage by doing so, will be reported to the stewards,” it read.
“We would not, for example, expect a driver who left the track on the exit of turn 8 to attempt to pass a driver in front of him into turn 1.
“Furthermore, any drivers who repeatedly leave the track on the exit of turn 8 will also be reported to the stewards.
“Drivers are reminded that if they leave the track they may re-join but only if they do so safely and without gaining any lasting advantage.”
