Robert Kubica says he expects his pace through Saturday afternoon's stages to be affected by the hydraulic problem that hampered his Citroen DS3 RRC during the morning.
Kubica was forced to use the manual shift on his Citroen after the specially designed paddle system failed on leg two's opener.
Not being able to try the stages at competitive speed on the first run will force the Pole to slow down this afternoon.
"The second loop [this afternoon] will be very hard," Kubica told AUTOSPORT. "We cannot use the experience of the first loop because the pace will be different.
"We will just go through those stages, but they are very difficult. There are a lot of tricky places; the pace notes were better yesterday than today. This afternoon, I think we concentrate on correcting the notes in case we come here next year."
Despite his early retirement on Friday - when he ran out of tyres following two punctures - and his Saturday problem, Kubica remained upbeat about his performance.
"I am very pleased with the hand," he said. "I saw some video from the inside of the car yesterday and I was very surprised and very pleased to see some of the things I am doing with it.
"Yesterday we went off the road and, OK, I prefer not to go off the road at all, but we made the good decision [to stay on the throttle] and come back to the road."
Citroen confirmed the hydraulic problem had been rectified in service, meaning Kubica can use the paddle gearshift and handbrake, which also runs off the same system.
