Edit... this post is to illustrate typical behaviour of the Auris bar graph fuel gauge and also gives some real world m.p.g figures. I filled up (brim full) 20 days OK and the car has been driven probably 70% or so of those days. Mixed road, urban, town centre and motorway. Climate control (air con) is permanently on. These are the "Fuel Bar" readings... Mileage start 0.00, all bars lit. Mileage 149. First bar goes off. Then comes back on. Then permanently off at 153 miles.
