The distance remaining to be travelled may be
wei
ghted by the time factor, depending on theuse made of the vehicle.

the distance which can still be travelled with thefuel remaining in the tankbased on the average
fuel consumption over the
last few miles/kilometres
travelled.

This value may vary following a change
in the style of driving or the relief,resulting in a large variation in the current fuel consumption.
If you only add a few litres, the value
displayed will be incorrect. Therefore,you must fill the tank whenever possible.
