Hi guys,
When it says TANK AVERAGE 14L / 100 Km. what the hell does that meen?

Your using 14 Liters of gas per 100 Km driven. ( kilometers Per Hour)

Car/Tank is averaging 3.7 gallons of gas for every 62 miles that you drive.
Works out to approximately 17 miles per gallon of gas.

Must be city driving but still seems a bit low.
If it's highway mileage it is definitely low.

Thanks
It is city driving
What about the other gages that say Currunt Average and Average, how r they diffrent from the tank average

the "tank average" display resets to zero automatically every time you fill up the gas tank.
The 'average' display resets only when you hit the 'reset' button.
