Hi I am in the UK and have had a new Rio 1.1CRDi for about a month and the ISG has never worked. I have been through the list of items in the handbook which are listed as to why it may not work but do not think it is any of them. We have had cold weather over here lately and only in the last week or so has the temp got above 4 degrees so that may have been preventing it coming on but as I say now we are at 5-6 deg but still nothing. When I come to rest at traffic lights or some such stop I have noticed the override light comes on as if to say it cannot switch on. Any ideas or should I return to the dealership? Thanks in advance.
