Force India driver Adrian Sutil has been cautioned for overtaking under yellow flags during the rain-affected Monaco Grand Prix.
Sutil and the team's chief technical officer Mike Gascoyne were summoned to the steward's office after the race, and the German was reprimanded for passing Rubens Barrichello, Kazuki Nakajima and Nelson Piquet on lap 13.
A statement read: "The stewards do warn the driver of car no.20 as to his future behaviour in relation to appendix H, Chapter 2, Article 4.1.2b of the International Sporting Code."
Gascoyne also indicated to UK broadcaster ITV that he had contacted the stewards in relation to the incident that eliminated Sutil from the race.
The 25-year-old was heading for a career-best fourth-placed finish when Kimi Raikkonen collided with him after losing control under braking for the chicane.
