\"Cons\" Has anyone worked out what the CONS reading is meant to tell me? Bottom RH corner of LCD display. I read the manual, and they don't say anything beyond "Consumption Indicator)... I tried looking at it as I'm going along, and I think it's trying to say "You've got 20 miles left in the tank", but it seems so variable as to be totally useless... I'm certainly not going to trust it, but I'd be interested to know all the same Ned |
