"After steering clear of mistakes for so long, it's really disappointing that such a small thing caused us to retire," Raikkonen said. "I just didn't quite understand the note, so we were a bit too quick into the corner.
"I tried to get the car back but unfortunately there was nothing to do and we went off. If there had been some spectators around then we would have had no problem to get back onto the road but it was in a place where nobody was there so unfortunately that was it."
Britain's Matthew Wilson had a similar problem to Raikkonen, but on Saturday, when he got stuck in a ditch in SS11. He re-joined under the SupeRally today and was classified 22nd.
The 2010 FIA World Rally Championship now returns to asphalt later this month with the new-look Rallye de France. The event has moved from its traditional home on the island of Corsica and will be based in Strasbourg, running from 30 September - 3 October.
