So I did a 100 or so moles today and have to say I was really pleased with everything about my new car. I thought to myself I'll check the mpg only to realise the trip computer wasn't available. I've checked the manual etc to see if it needs to be switched on somewhere (I thought unlikely) but figured I'd check with the people that know best. So before I go and make myself look silly does the trip computer need some intervention other than the odometer reset button? I would have expected something to be in the display at all times.
