Fuel Level
The Fuel Level menu displays the amount of fuel you
have remaining in the fuel tank.
The units are displayed as a percentage (%) of the full
fuel level. A full tank is represented as 100%. If you've
used a quarter tank of fuel, the gauge shows 75%, half
a tank shows 50%, a quarter tank remaining is dis-
played as 25%, and so on.
