So in summary, watch your coolant level and expect to add 1 litre between 15,000 and 20,000 miles.
It's difficult to believe that hoses could expand enough to accomodate about 15% more coolant. I'm curious, when people had the low coolant message, was there any coolant visible in the reservoir? If some was visible, I wouldn't have a problem driving it to the dealer for a top-up. If not visible, then you really have no clue how low it is and I would be hesitant to risk driving it.
