It will tell you when to get it done the first one will pop up at around 5800km which is when mine did and i am pretty sure there were a few others at the same mileage. I am at 11500 now and it hasnt told me to get it done again and i have no idea if it will wait till 13000 km is up or do it before. And 13000 would be in perfect driving conditions on paved roads, ect. So i doubt it would got that long anyways.
