I have just px'd a 2011 308 sw with cruises control for a new 308 sw allure. I travel to France a lot, and it was useful to be able to change the speed display settings to km and litres on the Eurotunnel so the cruise control displayed in km - much quicker than calculating en route. On the 2017 308, it is possible to change to ltrs/km for the engine performance monitor, but does not seem to change the cruise control display. Am I missing something, or is it just not possible? Fortunately the km display on the speedometer is larger than the old 308, but not what I would prefer.
