Judging from the Google referral that this website received, fuel consumption is one of top search I guest. As you can see above, fuel gauge warning LED turn ON while there's single bar left and blinking. 65 means estimated distance in KM before empty while 503.7 means distance in KM I have travel so far since last fill up. One perculiar data about distance to empty reading is whenever I fill up to full, it shows 600++ but as you can see above, it's only 500++. Maybe software bug.
