Oil change interval Auris 2.0

Hello, I have a little understanding problem I think. And the bad… my dealer also believes. Inspection at the Auris -> all 15tkm clear. Fitness and service check. So now the question. When the oil change is due. My dealer meant for the first time stubbornly after 15tkm or all 15tkm. In the manual is written on p. 261f. The following. Diesel engine: Oil service after 30000km (is displayed in the display) without indication of which diesel. One line below: Oil service after 35000km (is displayed in the display) without indication of which diesel. And in the service booklet stands for the work to be carried out: **Oil change after 30000km…. Who or what is correct now? Or should it be called…. Change after 30,000km the oil and if the display signals it before then it must be! I think the dealer is wrong with the 15tkm. How do you interpret this?
