Jean Todt insists he is happy with the safety of Brazil's formula one circuit at Interlagos.
Following recent stock car fatalities at the Sao Paulo venue's high speed Cafe corner, organisers vowed to make significant changes that will involve demolishing a grandstand.
But the work will only be done after November's 2011 season finale, and it recently emerged that a temporary chicane in place for recent stock car races will not be used by the formula one cars.
FIA president Todt, however, insists he is not worried.
"We are aware of the incidents that occurred at Interlagos in another category," the Frenchman is quoted as saying by Agencia Estado.
"We made detailed inquiries about the cars (involved in the crashes), not the track. Everyone can rest assured that all measures will be taken to avoid repetition of such accidents," added Todt.
He insisted that, in general, the level of safety in F1 is "excellent".
"For 17 years there have been no deaths in formula one. We know it is a dangerous sport, but the FIA works constantly to avoid problems like accidents and to reduce the risks."
